    hello guys, is this normal behavior for the drive chain?
    Clutch lifted and it starts to jump vigorously
    Experienced jerk around 3~4k RPM during 1st or 2nd gear thou. Not sure its related.

    Chain is way too loose

    Pull off the front sprocket cover and check front and rear sprockets

    Chain may also be stretched

    Or if everything is ok then it may just need the right tension put on the chain via the rear adjusters .... and a good lube

    At the midway point bewteen the front and rear wheels you should get arond 20mm vertical movement with the chain with the rear wheel on full extension (ie on the centre stand).
