Ripping Phantom 85 hard- and killing it on the first ride

[@TheLouisamite]

I can hear that one tapping like crazy,,,I can't believe it lasted as long as it did,,nice my friend

[@motoredbikemadness2061]

Yeah it got pretty loud when it was revving high, I thought maybe it’s the tank/gas cap vibrating lol. I just put up a vid showing the crank and rod- the big end bearing was way worse, more than 1/8 play because the cage fell apart

[@ronprice1819]

I built a bike like 10-12 years ago. It still runs today. I've put around 800 miles or more on it. The kit was an "SD stinger" . It's on a cheap Walmart cruiser huffy. I bought upgrade stuff from a place called pirate cycles. Which is long gone I think. I have a higher compression head. A straight pipe intake, a hub adaptor (no rag joint crap), think I have an ngk spark plugs and a better plug wire, better air filter, took the baffle out of the exhaust. I got 5 traffic tickets at one time riding it with a girl friend on the back haha. When my speedometer\odometer was working I was easily getting to 40-42mph. It has set long periods.nyears without starting it. I ran it the other night and let a friend try it. Thought he was gonna burn my clutch, but still works just fine. I always used Lucas semi synthetic oil. Broke it in with about 16-20 : 1. Then used 25:1 mix most of the time after that. Not sure what's in that engine or if it's just the same as other cheap ones but it's lasted great for me. Watching stuff now makes me want to get back into it!

[@motoredbikemadness2061]

That strong oil mix should help it out a ton in longevity, most people don’t run them long enough for it to matter anyways but when it’s getting into the thousands of miles it definitely helps keep the internals happy. I remember seeing pirate cycles ads on the forums back in the day lol at least there’s a lot more cheap upgrade parts now!

[@garylee7774]

Sucks man. I hate it when a new toy breaks!! Sounded awesome! Can't wait to see it fixed up. I may get one then.

[@motoredbikemadness2061]

Thx, I was hoping the 16:1 oil mix would make the weak bearing last but I guess not lol. I have the ms380 chainsaw piston for it now tho, gonna richen up the carb too and see how it works out

[@zychozen]

This is what we want

[@Bull3tBikes]

She pulls hard, looks like it can go up an incline pretty good too, I live in the pnw so we’ve got San Francisco type hills here, very long and very steep.

[@motoredbikemadness2061]

Out of the box mine was crazy lean I could tell it was hurting the low end. But was still surprised how well it did those hills with a 36t plus running way lean

[@mikemiller3303]

I have a phantom 85 version 2 with over a 1000 miles on her I'm a firm believer in breaking them in that means no speeds over 20 mph first tank of fuel and even after brake in you don't want to push it more than 85to90% throttle they can't take it even back in the day on my Suzuki RM 250 dirt bike same thing I'm telling you from experience ride safe brother

Don't feel too bad, mine broke on the 5th ride😂 Atleast you had a great view of autumn 👍

[@motoredbikemadness2061]

yeah I'm glad I wasn't babying it since the failure would be inevitable anyways lol. Have the new improved bushing on the way

[@soundqubedkiller5885]

[@trentbikes]

Guys, you're better off building a minarelli or buying a complete engine from california motorbikes for $200 like I did (wildcat ultra minarelli), it produces much more horsepower (5-6hp stock!), i dont think will have cooling issues unlike phantoms, has upgraded conrod bearings etc. I port matched the transfer ports on bottom end, spacer and the jug, going to widen up the exhaust port and the ridge inside (not in the cylinder yet), the skirt etc for more horsepower (up to 8-10hp with jog pipe, vm20 carb.) Next thing I gotta do is hone out the cylinder so the piston won't seize or soft seize when it gets hot and expands while the iron jug doesn't in time. Just make sure to replace bearings and take the metal shields off only in the inside on the crank case lol

[@TheLouisamite]

Is that the first engine they put on the market or the second one,,I have one of both,the first I got didn't last a day and the risk pin bushing failed so they sent me another one with a brass bushing an I have tried hard to kill it ,but it's holding up so far ,, an my first is to,I had to down size the rist pin to a 10mm pin and bearing,,so far it's still going strong

[@motoredbikemadness2061]

It’s the first version engine, the bushing looked like a Teflon layer on top of brass (I opened it up when it was still new). That’s awesome to hear the new brass one is holding up, I haven’t got mine in the mail yet but I was still naturally doubtful since it’s only 1mm thickness

[@TheLouisamite]

Be careful folks, an have a nice day,,to y o u all

[@Littleevil9975]

Hell yeah bro great video that thing is ripping nice

[@motoredbikemadness2061]

thanks man, it was actually pretty lean out of the box at WOT, I think it could pull even better with a larger jet

[@Littleevil9975]

That’s cool bro that should help to

phantom 85 is a good engine stock no so sure ones upgrade they are good on the carb we have a oko 21mm 38 90 jets on a 32 spoket also the cluch pads are upgrade good engine a sound great thanks for sharing

[@motoredbikemadness2061]

Thanks, just wondering do you think the G2 reed would be an upgrade over the Phantom 85 reed if using the stock carb? Since it’s almost the same thing but with 4 petals vs 2. I haven’t tried it yet

[@ELISRACINGTEAM]

@@motoredbikemadness2061 yes the stock carb no good . We use a 21mm / 24mm . Oko carb . The g2 is good

@@ELISRACINGTEAM thanks I’ll look for that special 10mm 044 piston, never knew they were available. I’ve got a ms380 piston in the phantom right now, had to shorten it a bit on a lathe but still using the 12mm bush for now. Hasn’t had much run time, will see how it holds up

[@motoredbikemadness2061]

@@ELISRACINGTEAM my stock carb was crazy lean it was barely able to run right, I’ve drilled out the main jet but I’m thinking of converting over to the G2 reed and a Suzuki AX100 carb

[@sundial6919]

Man too bad they bushed the motor . Was impressed w its responsive torque it pulled good . Did the plug look lean after it blew the bushings ? The chainsaw head dont seem like it would adequitly air cool either prolly heats up quickly

[@motoredbikemadness2061]

Yeah it was definitely lean, it would lose power slightly if I went from 3/4 to full throttle unless the revs were already up. Plug didn’t look ‘lean’ but I was running 16:1 with cheap oil, lots of carbon build up on the plug. I think the temp was around 150c when I checked with an infrared but the reflectivity of the metal throws it off for me unless it’s painted black

[@motoredbikemadness2061]

Did yours pull strong at low rpms? Mine seemed so lean that it was really weak until the rpm picked up, and then had an expansion chamber type powerband lol. Really needed the rpm to get that cfm/vacuum up in the carb. But I wonder if it might have also been ignition timing- did you see LA hovers phantom that would 4 stroke really hard? Mine is the complete opposite of that.. maybe the factory retarded the timing to make it run smooth after he made that video

[@sundial6919]

@@motoredbikemadness2061 my firestorm was really fat from factory i lowered the the needle 2 notches an seems right on now but still runs hot an did muffler mod to make have power . The air cooled motors are new to me . Ive ran the Staton friction drs for almost 3yrs w bullet proof 4k miles on 1 and 2.3k miles on the other and never have to worry bout them running hot . I ride them 30 or 40 miles w out stopping they do fine . Last 2 rides on the firestorm i did 30mile trips cruising 25mph w 36t sprocket heats it up pretty good even in 60degree weather . I dont think its gonna handle the 100degree summer heat we have here . I even have the big fin 6cc head but i only have 200 miles on it . It has really good low end torque . All my riding is street w few stopsigns so the motor is always in the wind

[@Adalbertomatos_]

So the second versión of this engine upgrade the wrisp pin and the bearing from the crankshaft and is better now ?

[@motoredbikemadness2061]

I have the new one installed now, only rode it for an hour or so since but it should be a lot better. Made out of brass/bronze like the old 2 stroke boat motors (just needs to run like 16:1 oil lol)

[@johng2779]

Harping on a it like that. Did you take the time to break it in. ? First run ? Is it any wonder these engines blow up. You have to take the time to break them in.

[@motoredbikemadness2061]

I did test it briefly before this. But it had a known issue at the time, I recorded it because I knew it was already guaranteed to fail. Nothing to do with break in for a bearing problem

[@jeremyclarkson6293]

Hi could you tell me if you got any problems with your phantom yet besides it blowing up after the new replacement piston

[@motoredbikemadness2061]

After I put in the new piston, with their 2nd generation upgraded bushing, I haven’t had any new issues. But the piston I installed was actually a chainsaw piston, I only requested the bushing under warranty since the chainsaw piston thing was already in my plans. One thing that needed addressing tho, is the motor ran very lean from the factory (needed the choke for a very long time before it would run normally), and after I added the chainsaw piston it was even worse and I had to drill out the carb jet larger

[@motoredbikemadness2061]

Yeah the other channel E.R.T. found a 10mm size pin 52mm piston on eBay but usually rare and you need to use 12mm like the stock phantom has. So you still have to use a thin bushing like the original phantom which will always be a weak point, hopefully the newer version phantom bushing (which I have now) is better
