    Ring end gap check is an a essential step you missed 😱 but the " don't leave things lose until later" is solid advice 👌
    Ride safe 🙏

    You made a top end change interesting. Nice shop. Fix your buddies dirtbikes and show some riding and bet your shop will have to hire more help.

    lucky that circlip didnt fly into the bottom of the crankcase!!!!....lol id be way more worried bout the circlip falling down into the bottom end then somewhere in my yard or garage!!!.... first thing i do is shove some clean shop towels down in there nice and tight and have a magnet stick in case it does fall down into cases but nice video otherewise

    I have a 2017 and there isn't enough room to clear the studs when taking off the cylinder dome . It hits the top motor mount bracket buddy told me I have to basically tip the whole engine . But nowhere have I seen this having to be done

    Can't believe you don't have a rag blocking the bottom end so that nothing can drop in there

    what was the verdict with the piston? Also, knowing the circlips can fly away at any given moment, why not just stuff a rag or paper towels over the opening to the cases? Great video otherwise, explained well, thanks for posting it!

    great video! i have a question tho... how do you know if ur running too lean or too rich on the carb???? u stay w the regular jetting if u use the same piston?

    • @byranmiller5015
      @byranmiller5015 Год назад

      Depends on your place like is it always hot or cold u probably would change jetting but if your to rich your plug with be oily and may had oil coming out the tail pipe if your lean it runs high idle or bogs on low end

    your old piston looks scuffed up around the skirt. is that from the piston rocking around and touching the cylinder wall or is it normal to look like that?

      I couldnt tell you exactly man, but it was a freestyle bike when i was riding it so the use it got wasnt super hard on it.

    If you're going to make a video explaining how to rebuild a top end, you should at least do it right. You should always put a rag in the bottom end, so that nothing can be dropped inside of it.... like a circlip.
