    Rupp / Fuji / Gemini 80cc crank removal and seals? ( Fuji 80 F480 )

    pich shows right side up when i save it and view it. looks like the thing never went to waste over the years. it's incredible how much stuff folks recycle. looks like cool little project and possible begging to a cool little rod one day.

    WOW thanks for the pic! That make sense. Now i'm curious to see what some different fire slot patterns would look like on clear head with a slow mo camera. i know it wouldn't change much but, it would be cool to see it not work, i know that sounds odd and or hopeful. I have to wonder if any...

    just came across this reply doing some googling. any context behind your comment? there is little information on fire slots on the internet. or at least not super easily available so any input is appreciated.

    What can you tell me about HS40 ball bearing covers? (HS50?)

    if that's true it sounds like i could just get measurements form someone and pop my crankshaft on the lathe for a quick minute. as if that wasn't cheap enough, i bet someone has measurements for the bearing as well. all i need now is to source a side cover! :)

    What can you tell me about HS40 ball bearing covers? (HS50?)

    What can you tell me about HS40 ball bearing covers? are there different size ball bearing versions? wouldn't be the same part number as an HS50? Does it matter the crankshaft in my HS40? I ask because i'm under the impression there were different crankshafts for the HS40.

    139QMB 50cc GY6 engine build

    yeah it's probably gonna cost $140. you're on the right track trying to source from something else can't believe i didn't think of that. what about chinese pitbike engines and aftermarket kits for the honda trail 50 and 70 or DrATV?
