    Welcome, and very well explained.. I’d say your rollers are a bit Heavy hence the long pick speeds

    Have you tried lighter rollers ?? Maybe 6.5 or 7 grams would suit better ? And also I think the red springs will hinder your acceleration too

    The red spring are very stiff and take a lot of centrifugal force to open the clutch, may explain the issues your having ?

    Well I tried today with 5,8gr but they were light,becouse it was spining in high rounds but it wasnt going really well
    Only problem is in the start,it has really weak start and while driving in full thortle just like I wrote in first post
    The only purpose of this bike is for doing wheelies
    I dont have problem doing wheelie at around 20 km/h becouse that is the timing of the best acceleration
    But again I have problem doing wheelie after first one,becouse then I need to let the thorttle and wait for few seconds for rolls to "calm down"
    Well I wrote long text,didnt wanted :D
    But conclusion is that he wont accelerate in lower rmp and lower speed

    Ok I see, I’ll put my money on the red clutch springs,there too stiff. Too many revs needed to open the clutch, not good for wheelies

    I like your style. I also enjoyed doing a few wheelies back in my younger years :D I'm guessing you are from Croatia right? I've been told pulling wheelies is a very popular pastime in Croatia.
