'79 Yamaha XS750 First Start! (Indy Day 4)

[@BillAndersonNS]

Thanks for taking such good care of the 79 XS759 triple. I really love that bike. I bought one brand new in 1979 and as I didn't drive cars, it was my daily driver until October 1982 when it suddenly ground to a halt on a 460KM road trip. I had it towed to my girlfriend's apartment garage. I lived in a different city so the bike sat there over winter. In the spring I got my car drivers license so I was in no rush to diagnose and repair the XS750. Life got in the way. In a couple years we got married and built a house so the 750 got moved to the house. Five years later we moved across country and the movers moved the 750 as well. Where it sat in my garage for many more years. Then I had the opportunity for the Community College Motorcycle repair program to use the 750 as a project bike. Within days they told me that the problem was caused by gas leaking into the crankcase and diluting the oil to the point that it caused the engine to seize. (Get rid of those damn vacuum petcocks with no OFF position before they destroy your engine too !!!) They asked if I wanted to source parts and try to fix it. Because of temporary money issues, I (stupidly) said no. And I have regretted that for years. The bike was in almost perfect shape except for the engine and the rusted exhaust pipe. I have never wanted a Mulligan so badly. So thanks again for taking such good care of this beauty. It's a gorgeous design, and there is nothing like it on the road.

[@mmichaeldonavon]

Ivan, loved that. I once bought a "basket case" 1984 (I think) Honda 750 - New chain - one new carb (out of the 4) - reworked the front shocks - removed the heavy stock exhaust, installed Headers, from a "4 into 2" exhaust system. Was loud - I had to ride with ear plugs. Was Black in color - all of my riding gear was Black. Put on a tiny wind screen. Was a really cool machine. I had to hang on when in 3rd gear at 6 or 7,000 rpm. :-) Loved it. Rode it two years then sold it to a guy who had been begging me to sell it to him. :-) Love the bikes.

[@Mtechthewise]

I have a 1984 Yamaha XJ750RL, it has the YICS system, doubt that many people remember that innovation!

[@notajp]

I had an XJ1100 several years ago. Had all the bells and whistles with mucho power......

[@PineHollowAutoDiagnostics]

My 1982 Yamaha XJ750RJ Seca has YICS. Sounds like a gimmick...just a passageway helping to balance the intake manifold pressures lol

Nice to see the old bike back on the road, sold mine 1980.

[@StarChasersHere]

I bought mine used a 1978 xs750. She had 10k miles and expired in a fire in our town with 89k miles. After the fire some parts were reusable. I found another one, same model for $250.00 with 11k mileage. Everything was rebuilt to specks. Watching you working on the carbs, you didn't show your viewers the carb syncing with vacuum gauges. This is very important when slowing down to prevent the shot gun effect that will harm the motor. I like the long runs and during hot days you can here knocking going on when you get off a HWY run. The xs850 has the oil cooler on them and the 750 will work too. It's a must have to reach 89k with no problems. She has a full dress, Vetter Windjammer, saddle bags and the large Vetter trunk and King/ Queen seat with back rest. One more note, use the 850 slotted brake disk's, the 750 non-slot's suck.

[@hightttech]

5000 miles! Looks like NEW. AWESOME find.

Got very lucky on that jet thread issue. How nice to find something on your hot list and its in low mile and clean shape !

[@htownblue11]

Good stuff Ivan as usual. KZbinrs and some viewers seem to think a carb rebuild video is worthless.....today you showed it’s not always an easy fix etc. It’s good to see that even experts run into one off problems like a broken jet stuck in the carb. Have fun on your ride friend and be safe.

[@CubasAutomotive]

That bike looks & sounds amazing. I totally agree with taking care of the carbs 1st, as they're usually the worst part on a bike. Besides maybe tank or brakes. Can't wait to see it in motion! 😍🤩

Dear Ivan, great interesting bike, I did not see the entire video, but I noticed that the tires might need to be changed and I am not sure if I am correct or not, so be careful Bro. when handling these motorbikes and never go speeding.

Nice bike! When were the valves last adjusted? Some Yamahas are keen on letting the valves to sink into to the cylinder head and cause zero lash and burn a valve. I recommend adjusting the valves before riding hard.

[@mudemmeonick]

Ivan, WD-40 does eat away rubbers and plastics, it excells as glue remover and that says a lot. Give it enough time and it will even strip paint. So be careful. The most safe are usually those lubricants that can be used for electronics.

[@PineHollowAutoDiagnostics]

I also like WD-40 because if you spray it in your eye, it doesn't burn lol

That was cool seeing the 3 carb running side by side. Neat fix! Now i am curious to know if you and your brother usually talk in Russian or just English? Lol. That is sweet looking bike and that will be fun to ride!!

[@michelbrown1060]

Please be decisif when shifting 2 nd gear, the throw is long and if you miss it too often, you loose the 2 nd gear, and than you must go from 1 to 3. .

[@stevensapyak7971]

4.20.21. These bikes are known to have issues with second gear not staying engaged, due to the dogs on the gears being rounded off because of previous owners slamming the gears ramming up to speed❗️

[@PineHollowAutoDiagnostics]

Earlier models yes. By 1979 I think Yamaha addressed the issue...

[@Blazer02LS]

@@PineHollowAutoDiagnostics Not really, the 78-80 XS bikes all had the second gear dog issue. If they are not an issue already it takes moving one washer to the opposite side of the gear to make it lock in better.

[@jimbe01]

Ivan, Are you sure that those “O” rings are auto fuel tolerant? Don’t want to risk fuel connection degradation and resulting fuel leaks (hopefully initially minor) on the road. Just ask’n.

[@PineHollowAutoDiagnostics]

They were actually viton rings. But never had a problem with regular o-rings in many fuel applications.

[@davidvierling684]

Ivan, please set valve clearance and adjust cam chain. This jewel should not have that much engine noise.

[@gtemnykh]

It might just have something to do with this bike being started for the first time in 5 years. At 5k miles I’m not sure how much valve clearances would change but I suppose that initial break in mileage is when they might

[@PineHollowAutoDiagnostics]

I will check the cam chain for sure 👍

[@dennisbailey4296]

If your headlight is an H4 which it could be you can buy a really good quality LED light bulb for that and they are amazing! I have one on my own bike!! All the best from Canada

[@mudemmeonick]

Thank you for being a disrespectful a-hole caring only about yourself and blinding everyone else on the road. Your headlight enclosure wasn't designed to accommodate a bulb with such higher lumens output and different pattern. It will therefore never ever provide a proper pattern due to bleeding. There's a reason things are done as they are. Retrofitting things usually never ends up giving decent result and when it comes to lights, claptraps from old housings and newer lamps are quite easily the crappiest of them all.

[@PineHollowAutoDiagnostics]

I actually prefer the more yellow light of a Halogen bulb...
