I lost my old top end because I lost my cooling line. Got it as a running ski and it didn't give me a single issue all year - I promise you'd have never guessed it looked like that in the carb if you rode it.
Anyway, just one of those things I guess.
What do we think went wrong? I think he just had a hone on a scored cylinder and put stock bores pistons back in there, so I'm assuming a cyl might have caught a piston ring.
I hate poop like that. That's way worse than me!
I absolutely reamed that carb body with carb cleaner and compressed air. New oem mikuni build kit, new fuel filter. I was so confident I loaded it up and drove two hours, dumped it in the water and just took off hoping that I'd got it right...

When I was big into pitbike racing I toyed with the idea of just putting together a "pre upgraded" CRF110 for people because everybody buys them, does the same 6 mods and rides them. I'm gonna figure this is similar, but for a RN superjet.
Glad to finally see some thought put into the made in china question. I've had parts made in china that far surpass what local shops will give us, for half the price.
