After 3 months, I'd guess that the replacement parts aren't coming! I got lucky and picked up a returned engine for $35 on Ebay with a good cylinder. Did the mod with an MS380 piston and the 2 bushings, 10mm wrist-pin and cage-needle bearing. Added an KX85 pipe and it screams! Hope it holds up better than the factory one did!

@omargdottin 2 года назад

Wich bushing dimensions did you used??

@myshut9937 2 года назад

@@omargdottin Sorry, I just saw your post. I used 10x12x8mm long, shortened the 10mm pin and used needle bearing.

@gabrielcarvalhog.c.r. 2 года назад

if you polish the exhaut duct it will increase top speed and performance and also get a foam air filter like the uni filter, its because of that the mixture fells rich but in reality it doesnt get enouf air thru

man im glad someone finally showed a proper fix . not that i have a phantom nore would i buy one at this point . good job on that . how ever looking at your expansion chamber pipe . i have to ask the stock pipe that comes with the phantom is way bigger. did you mod the pipe to fit with no restriction? i ask cause in the video it looked like it was a bit small compared to the stock pipe .

@jamesfulerten8494 Год назад

The problem of your motor "4 stroking" may be the reed in the reed valve manifold. If the reed is to stiff it can cause the incoming air not to mix properly with the fuel as it moves over the reeds. Less stiff reeds could be the fix there.

Phantom 85 head, cylinder, piston, crankshaft in a YD100 case? Does this help a lot with airflow through the transfer ports at the bottom or something? Since Phantom 85 case doesn't have those.

You have to drill tiny holes in the bushing to allow oil to penetrate to the pin.

Winner. Not only that the little end will spin round and move. That's bad. And the sides of the bush need machining. No wonder it still rattles

just ordered my phantom v3 they say your supposed to run it 20:1 during breakin period this seems very rich to me but ive heard a lot of people saying they run it 25:1 during breakin and then go down to 36:1 but they reccomend 25:1 after break in. Idk i dont know it all or anything but could this possibly be why some people are having problems with the wristpin bushing and piston rings? someone who knows something lmk cuz im not trying to blow mine up lol

@mikerammelt2420 2 года назад

U'mm that small end bush is no good. It needs to be "pressed" in (interference fit) otherwise is will spin in the small end and cut the oil off to the little end. That's bad. Those oil holes need a drill bit through them with a nice radius to catch the oil. That old bush has come loose and moved around. Being with a split is correct. Every little end bush I pressed in and machined was steel back brass or copper. Go to an engine shop and ask to see a small end bush out of a diesel and that's what you'll see, but Big. That little end failed due to lack of lubrication either because it came loose as is evident by those solid brass Bushes. Your going to have to knurl those and Loctite them. Dodgy as. I'd check the little end with a telescopic ball gauge. Because if that guy made those bushes to size they shouldn't fall through the hole. What's the OD of those. Ones wrong. Don't run it to lean. Two strokes are supposed to smoke. Back to your vid
