Yamaha Rd 350 Top Speed!!!

@@shawnmclean7932 You apparently have not had a crash yet. Losing a bunch of skin is no fun. The suspension and high speed handling of these motorcycles is not great. The RD350's did not have a lot of weight on the front wheel, which is why they are so easy to wheelie. A little patch of gravel, a pothole, or even a dog running into the street would result in a long, painful slide.

RD 350s ran like scalded dogs. I loved mine back in college in the early-mid seventies. Some of my favorite stories of triumph and miraculous survival are about me and my RD 350. With the right tires it would scrape its footpegs off and keep going. Great bike. My ex still has scars from the exhaust pipe.

At last someone alive that had an rd .

[@donsutherland5706]

I raced a 1973 RD350, a 1981 RD350LC and a 1983 RZ350. Top speeds were 107, 112 and 120 mph. I was an expert race tuner and always had the fastest legal production bike on the track. There were lots of little tricks for getting the most out of these bikes. You needed to experiment with the main jets because in Canada, they always came jetted rich so they wouldn't seize in cold weather. The RZ350 had a multi-layer head gasket so I used only one of the layers for more compression. I had a couple of thin washers so I could adjust the needles by half a notch. My best trick was using a rev limiter that cut the ignition off for 55 milliseconds, just long enough for a shift to go through. All I had to do was put pressure on the shift level as the revs approached 10,000 RPM. It didn't hurt that I weighed only 135 lbs.

[@theblytonian3906]

Listen to this guy. He knows what he's talking about and speaks truth without imaginative exaggeration like the rest of you t0ssers. Back in the day I owned and rode an RD350A, rode the new RD350B in '75 when a mate bought one, compared both with a '73 CB350K-4, and currently own a 9/85 RG500G (since 3/86 bought new) and an 9/98 RG250T (since 1/00 also bought new). The RD's strength at the time was its acceleration, not its top speed. All three of those 350s mentioned were good stock for around 105mph/170kph. Nicest street Yamahas to ride (best handling) were the final unfaired mid '80s RZ350s and RZ250s & later faired TZ250s. That '98 RG250T of mine does 210kph true, circa 215kph lying on the tank if you allow it to wind it up. Acceleration to 170kph is linear. The square four 500 is linear to 200kph, tapers off but still steady and quickish to 220kph, steady but slowing to 230, and slow to wind up to 240kph-ish. When near new I had mine through a calibrated Police radar registering it at 242kph.

[@kellyjackson7889]

anytime you shift before 7500 rpm on a 2 stroke you are effectively 'short shifting'

[@EpicMallCop]

.

[@kellyjackson7889]

Moto Mafia First off the bike red lines at 9000 Secondly you assumed my comment was based on modern bikes. I've owned and ridden many 2 stroke both air cooled and water cooled variants. The air cooled bikes are very peaky water cooling then automatic variable exhaust mechanisms (see ATAC YPVS SAEC) broadened the powerband/torque curb.

[@EpicMallCop]

Yes you are right on the last part , Ive ridden one of these before they can go up to 9000 but it produces peak power at 7500 look it up . Secondly I you could have just said power valve instead of all the shit you wrote.

[@kellyjackson7889]

I wasn't arguing peak power as a matter of fact my original comment specifies "anything lower than 7500" You indicated it "redlines at 7500" so what you are saying now is you meant to say it peaks @ 7500 but again thats what my comment suggests so there would be no reason to disagree in the first place -right? :) "Powervalve" yeah I coulda. Also my original comment is being somewhat facetious - if you watch the video again and look at when he shifts Vs the objective you might see what I'm getting at. Peace

[@109goofy]

+Kelly Jackson that RD is a pre water cooled, it's only got reeds, but I agree I was cringing at home short shifting.

Drove one of these across Canada and back. Woke up one morning and the front tire was flat - no other problems.

[@nzmcdonagh]

I have had my RD 350A since 1975.I raced it extensively in production racing in New Zealand back then where the only changes allowed were to handlebars tyres and sprockets. Mine was one of the fastest and timed at 105.8 MPH on a long straight (Hawkesbury). Showing nearly 120 MPH on the speedo!! It had a 16 tooth frort sprocket and a 39 tooth rear sprocket and was pulling 9500RPM in top - flat on the tank in leathers.

[@ronprince1478]

John, 108.2 flying quarter Whangarei area a long long time ago, I miss the sound of that little engine working.

@John Mcdonagh I had one as well. The only bike I owned that I never fell off, and it was far and away the fastest! I have a brand new set of factory disk pads, still sealed in their bags if you're interested. Threw out the original handlebars when we moved a few years back - I had SS bars on mine rather than Ace bars. I'm in Wellington drop me a line if you're interested in the brake pads.

Had 4 of them over the years growing first one at 15 years old after a KE100 first bike. It was my favorite bike ever was not the biggest fan of the RD400 when it cam out but the RD350 hit the sweet spot for me. 😊

[@harrylime5147]

The mirrors cost you about 8 miles an hour, the turn signals didn’t help either. If you had a number plate that was at a 45degree angle mounted between your headlight and the top of your gauges that you could tuck behind, and if you had a 16 tooth Sprocket, tight leather’s, and high pressures in your tires, with your transmission oil nice and hot, and motor oil instead of Grease in your wheelbearings, you could get over 111 miles an hour by the speedometer, if where are you are riding is not above 3500 feet in elevation. There is also one modification that Yamaha put a service bulletin out saying, two half-inch holes, one on each side of the airbox. Fresh NGK b9hs non resistor spark plugs with only one heat cycle on them, and clean pistons, that were matched gram for gram.. it also helps to modify the way the front fender is installed, get it as close to the tire as you can at the leading edge, but you have to allow for the tire to grow just a bit. Make sure your chain and sprocket‘s are not worn..worn sprockets and chain can cost you up to 6 hp. But don’t start a race on a brand new out-of-the-box chain, because it needs to be broken in, I have seen a brand new chain on a machine I was riding in an endurance race come into the pits on its first gas pitstop, the chain was turning blue. spray with chain lube and the chain lube sizzled....Cut the two lock nuts off of the oil pump cable, and turn the Cable in and adjust the cable so that the oil pump only reaches full stroke, when the throttles are wide open. Oil lowers octain ,low compression ratio engine cannot burn oil. That’s why you see white clouds of exhaust from 2 strokes I made sure all of the information I just gave you was done to my racing machine. I got my bone stock RD 250, not 350, to indicate 111 miles an hour on the front straightaway at Summit point Raceway in Virginia in the 70s& 80s.. I had no mercy on the clutch, but I babied the transmission with every shift. The original clutch lasted me over 100 races. It’s still in the machine today. I never had to touch it. Won 6 championships-2 time national champion on my stock 1974 RD250- with a drum brake (I tried a disc in the front, the machine was slower on acceleration, slower steering, because of that Gyro disc,The handling was worse on bumpy high speed corners because of added weight of the disc and the caliper, made the front wheel chatter and slide around tight bumpy corners because it took longer for the suspension to recover between each compression...energy into the heavier spring,oil in the forks to control the spring.... The heavier the wheel, the longer it takes to complete that cycle. If the wheel isn’t ready for the next ripple, the wheel well chatter/bounce, and you will lose traction...and disc brakes drag) I tried both disk and drum, and I was much faster on lap times with the drum. I also liked the fact that I didn’t have to be as careful with the drum doing 10/10 braking as I would have to be with a disc,Especially in the rain.

[@ColdSmokes]

2vintage Are the point gaps set to EXACTLY .014"? Be sure of this.

[@Bilytkid]

I used to own one. The timing is critical. I used a dial indicator (in the spark plug hole), with an electronic point checker. IIRC, the individual point (for that cylinder) should just begin to open at 2 MM, before TDC. The more accurate your timing, the better it will run. Also, the float levels must be exactly the same on each carb, with synched slides. After 15,000-20,000 miles, I'd install new rings, which is very simple to do. (or if had a few years on it).

If I remember right, it did the quarter mile in 14.2 seconds. I did get it over 100 mph but it sure felt light. My buddy had a Honda 650, and this Yamaha would take it up to 60 mph, then the raw power of the big Honda 650 took over. Loved this bike, great handling. Would buy another one in a heartbeat.

[@swiftyhernandezSr]

Great bike the RD350. I learned to ride a tire to the edge on my RD350. One of my all-time favorite bikes. Pretty nuts to do a top-speed run wearing short pants and short-sleeved shirt, though. I hope you never have to learn that doing any top-speed run, wearing short pants and short-sleeved shirt is not a very smart thing to do...

[@dougiequick1]

Yes of course but one could easily argue that motorcycling in general is not particularly smart unless it were the only transportation one could afford. It's not real smart to take any risk unless one factors in the reward of sheer joy....All things considered compared to other crap done on bikes? Riding in shorts for 5 minutes on an empty dry highway at less than 100miles an hour on a well maintained motorcycle? NOT much risk at all compared to being in full protective gear riding balls to the wall for many hours on the twisty public highways

[@garnetsisler9249]

I've had both a 1974 and 75 rd350. A stock 350 will do 105 mph tops. Stock motor has 32 hp. and if memory serves me right the 1/4mile in roughly 13 -14 seconds. First 3 gears you can pull wheelies. I still own my 75. Changed the reed valves in it and its bored to 4th over.That's the max.Will do 115 mph if not more but never pulled top gear properly. These bikes are very sensitive. If you clean and polish the ports, change the jets cut the carb slides, rework the air box for better air flow and find a better exhaust then the stock you can have a quick cafe racer. You might have to change the plugs to one hotter to much and you'll cook the motor. But you might want a pro tuner to do the engine for you to get it done right. Front forks on these bikes are to soft need a better progressive spring and different oil. The rear shocks rebound is to hard and the bike could use another inch of clearance. Nothing like dragging the pegs going around a corner and hope you don't catch anything to pitch you off. The stock exhaust on them was better then most after market .That's the way Yamaha designed them at the time. They were the bike to beat during the mid 70's on the smaller tracks because they were so light and nimble you could just flick them from corner to corner and beat the 500's and 750's.On bigger tracks they could still win but it was harder because they couldn't get the top end the bigger bikes had going down the longer straights. Overall this is one of my favourite bikes other then a Suzuki Gsx750 a Ducati 900ss. It's fun being the underdog when you can beat a bigger bike in short drags or on those back winding roads.

A friend of mine bought an RD 350 and asked me to ride it home for her as she didn't have a cycle license yet. I got to a long stretch of road with no traffic and decided to see what it would do. Redline started at 8,000 so I had to get to that. I was in second gear wide open throttle and when the tach hit 7,500, it almost immediately jumped to 10,000 with a corresponding jump in power. They were a pocket rocket if you didn't drop the revs below 6,000. They had to run on premium fuel back then and I don't know how well they can run on the crap they call gasoline today.

[@cgdrider]

I bought an RD350 in 1974, added expansion chamber exhaust, clip-ons, full racing fairing that I got from a friend who was sponsored by Webco. After a ride to the mountains on the way home and a slight downhill desert road I got my RD350 beyond the indicated 120 MPH for several miles, maybe to 130MPH.

[@harrywilson822]

95 MPH is slow but fast enough for that road you were riding on, riding safely on it. You were shifting a bit early, not going all the way through the powerband. Never the less nice sound and good safe riding there. Stay safe out there.

You already know, but just in case...it's a TWO stroke engine with a steep power curve...same engine Japan was sweeping all international races with...

[@bobbyphillips2538]

They shriek, like a Banshee, because Yamaha used essentially this same engine for their Yamaha Banshee quad, as the abnormally long shift lever needed for this motor when fitted into a quad chassis. The RD350 itself had phenomenal acceleration, and would run with most 650's and 750's until 65 or 70 mph, then the displacement advantage the bigger bikes had was to great for "light and quick" to overcome. But, and those who rode or owned one will agree, when you accelerated full throttle through the gears, the engine screamed, you heard the intake of air through the intake tract more than anything. It would lift the front tire a few inches, and pull so hard that the frame, no where near as stiff as today's, would flex and the bike would for lack of a better description, "shimmy" or wiggle,and go! This is one of those rare machines, that have heart, a soul if you will. If it finds itself alongside a bigger bike, it will run its heart out to win for you. Then you roll home listening to that cool 2 stroke twins lovely exhaust sound. It's given all it had and reminds me of a young puppy, that's run its heart out, and is wagging it's tail, tongue hanging out, looking at you, "did I do good? "

I had done a lot of that and melted my pistons riding double on an upgrade 120 indicated.on pump gas...I know it was stupid but such are the actions of silly 19 year olds....was like a sudden compression release of a big rig sound I am sure it would have been glorious from behind in the night with all the cherry hot fragments blowing out of the chambers....I just had to be going faster than all the other couples I was riding with lol ....still kicking myself 50 years later whenever I think of it. Nowadays I am riding an MT09 which power nature reminds me so much of the old RD even though though its a 4stroke triple that is WAY WAY faster than the RD ever could be and better handling in every comparable way except pushing them around in a garage since the RD was considerably lighter

Too front heavy for wheelies, but would burn a patch in the road while already doing 30 mph by downshifting into 1st and gunning it.

I love your vlogs road to 10k will be easy

[@thinkpadBentnoseTheBlind]

Nice ! I made it to just under 190kmh [117mph} on my 2 stroke kh400 once . Swap that rear sprocket for one with 1 less tooth and then see how fast it goes.

[@babylynpenaranda2873]

Stock gearing on a 1973 RD-350 (maroon wonder) was 80 mph at 6,000 rpm. Theoretically 100 mph at the 7,500 redline. Yes, a lower redline than Honda's CB-350. You could increase it up to 8,500 if you replaced the stock wrist pin caged needle bearingss with the higher rated ones from a TZ-350. The TZ had a 9,500 rpm redline but you could reliable get 8,500 on the RD-350 just by changing the bearing. If you overrevved the stock bearing you would crack the bearing cage. This bike also has the automotive coil hose clamped to the down tubes mod described in "Cycle" which lowered the idle speed and stabilized the idle as well as making starting easier by increasing the spark plug gap to 0.035". Cutting a few coils from a DT-250 fork spring and putting one cut section over each RD-350 fork spring propped up the always sagging front end. I also put a piece of felt soaked in fork oil under each rubber wiper wrapped aroung the fork tubes to keep the fork oil seals lubricated and protected from grit. Those mods as well as Boge Mulholland rear shocks and Goodyear Eagle motorcycle tires helped the suspension and handling. And then Spectro Golden T synthetic oil in the tank stopped the mosquito fogging that happened with mineral oil. This video 350 has rear set foot pegs and expansion chambers so someone had ambitions to race. I LOVED the sound!

[@bretthoffman2128]

Loved the video, I’ve heard of RD 400 also, but you were going fast. I let my bike idle for a minute or two, after most rides, but that’s me

[@superzuki5831]

I had one just like it in 1982. A few friends had them too .

[@crisXD2010]

Awesome videos man .

[@2vintage]

Thanks a lot!

[@james-gb3jk]

I pull that in 2nd gear on the busa.. busa is the only bike to scare me. The 350 is a cool bike .. great vid.

[@edarmstrong9389]

Why did you not pin the throttle wide open till redline?

[@dj6769]

You’ve got some intermittent plug fouling? I bought a brand new one in 75 it was ahead of its time a rocket up to 95 and the wind forces it back. The oil injection was a chore lots of memories 👍

[@bdogjr7779]

Back in the late 70s I had a couple of 73 RD350s with # 250 main jets, some mild port work on intake & exhaust,Wiseco Forged Pistons, Boysen Reeds & some beat up repaired a few time J&R expansion chambers & they would both do more than 120mph. That engine sounds pretty healthy. you may want to try a different gearbox oil to cure that shifting issue. If you ever want to trade for my 02 Busa I will make you a good deal. Good luck with your RD & thanks for sharing the RD experience so I can relive my Teenage Years.

[@ewhornot2205]

I had 5 RD 360 in the old days. Everyone of them ran 114-116 MPH stock out of box. My 250s ran 106MPH OUT OF BOX.

[@jakev9317]

Nice video! I love older bikes!

[@2vintage]

Thanks man! I do too!

[@lespaulplayer23]

The Yamaha RD350 iconic bike along with the RD250LC, RD350LC, RD350 YPVS, RD400, RD500 as well as the Suzuki X7, Suzuki RG500 Gamma all epic 2 strokes 😎 👍

[@jeffpolakiewicz8174]

I had one. Had charing problems.Gave it to my girlfriends brother around '96 or"97.If you got one of these around the Pikeville Kentucky area that one was mine.

[@buzzy1011]

Aaahhh. Rd 350… my first street bike…. That thing used to eat Honda 750’s 4 strokes for breakfast… lots of fun… be safe….

[@davep4610]

I had an RD350 that was made in '76 or '77 and I bought it in '80. Only had it one year before it got stolen........ I know I hit about 95 on it, might have brushed 100, given constraints of finding a long straight road without traffic. Fun bike. I rode it from Seattle to L.A. and remember that the gas tank was very small so it could only go about 75 miles on a tank.

[@karlporath8904]

I had a 74 RD 350 in th late 80s. If tuned right and the reed valves aren't wore out the power should come on like a light switch@ 6500 rpm and pull hard to 9000.

[@427zoh6]

My 350 with 28mm carbs off a 400 and Bassani pipes would wheelie and top out at 125....bet the crank seals on his bike are leaking....doesn't seem to run very well.....should wheelie like a MoFo! even stock.

[@robertjohn9684]

427zoh6 my aprilia rs125 could almost beat that

[@zippytbo]

Same bike, pegged the speedo back in 1975, on an interstate highway late at night.

[@jamesstewart9506]

That is a good tuned RD all the people saying otherwise just do not understand 2 strokes I own 13 RD 350 and 3 RZ 350 and all of mine are well tuned like yours is you can get them to go 100 mph with the stock sprockets and around 110 mph if you put a smaller one in front, great bike glad to see it running like it was intended to run

[@yvonjasser]

James Stewart I've you have a lot of too rich tuned RDs then, that bike was 4 stroking 1/2 throttle like crazy

[@toma9835]

I built the same bike back in the seventies. The tach would spin all the way back to zero as well as the speedo. I miss it a lot.

[@grayharker6271]

In 72 I had a brand new RD 350. I knew how fast would go with me on it. But I didn't know how fast it could go. So I put my little brother on it. He couldn't touch the ground so I would run along side until he got going and stopped. He went down the road and came back. He said your helmet and goggles were too big, the wind got under them, so I couldn't see the speedometer after 110mph!!

[@donalddday7741]

Got mine new in 75,looked like this after I put on the things you have but I had chrome Chambers,ran best at .50 bore,was a blast to run in the Bay area most fun in the Santa Cruz mountains on Skyline Blvd and racing stop light to stop light

[@ronaldcaraway8184]

Yeah I had the R5B, it was before the RD. Mine was a 4 speed. It would do 110 easily then run out of legs. Once that power band kicked in you held on for your life. They put that same motor in Banshee quads later on. With expansion chambers they are frightening beasts. If you ever have to rebuild, go wisco pistons, barnett clutch plates and expansion chamber mufflers and you have never felt anything like it. That high rpm rip is crazy.

[@philipleizgold2332]

5 speed

[@king20jdmjbweld65]

the older they are the more fun they are

[@prasanna8899]

nice pickup

[@pierresassareu5487]

Cool video. I saw a Solex too inside garage👍

[@pamujular]

The sound is music to my ears:) I rode my brothers RX 100 was fun, it’s tiny compare to RD 350

[@abaha9898]

Nice to ride out and relax

[@fredboat]

Thanks for the walk down history road, Enjoyed I had one of thoses in 77, They all had the two cycle Vibration at high speed. And yes wear proper gear. Glove, pants. Don't puss those old girls to hard.

[@richardstump4582]

Alright!! Great JOB

[@shawngleason1345]

All the old 2 strokes had the shakes had something to do with the 750's being called the Widow Maker

[@GlennFromHB]

In 1975 I was about 19 years old and working at a Yamaha shop. I bought a 1975 RD 250, because it had straight primary gears, and the 350 had primary gears to reduce the noise. We put 350 pistons and cylinders on it, We ported the crap out of it, put after market expansion chambers on it and made it into a cafe racer. Boy I have stories. The power band on it started about 8,000 RPM and went past the 10,000 RPM maximum label on the tech. It was grand fun.

[@Drobium77]

My 1973 GT380used to do 97mph , that was flooring it

[@tonieveritt7045]

One of the best bikes in the 70s the good old days

[@colintoghill2251]

You have no clue how to make a 2 stroke perform, as the powers coming in you change up??? You're not even sure what gear you're in, going for one that is not there?? Do revs scare you? Leave 2 strokes alone if you don't know how to get them on the boil.

[@domsteward358]

Hahahah, you didn't, by any chance, used to own a Suzuki gt750 did you? I thought maybe your comment on "getting it to the boil" might have been a reference to you owning a ketttle in the past

[@abaha9898]

Love the smell of 2 stroke sweet smell

[@leecornelius964]

90 mph, that's not it's top end. The one I rode in the 70s would do 120 mph.

[@silevesileve6279]

@john thonig My 1977 RD400 tops out at 110mph - per the speedo, so take in about 10% inaccuracy. No fairing/windshield
