    check your compression, also try whipping a new plug in there. but it does sound like the rings are going

    should be over 7 kg/f you can get away with 5kg/f but that will mean your rings are going out

    The wire that goes on top of your ignition coil, it's either slipped off the pin or the ignition coil has had it. Squeeze the metal bit on the end of the wire so it is a tighter fit on the pin and it should be fine, had an identical problem. Btw, yes, you do know me off Instagram ;)

    Bump to anyone that’s reading this so this afternoon after my previous post last night it rained heavy the bike started to splatter all throughout the river range it was ringing alarm bells at the time I did think to myself recording years ago at this with water related get inside the carburettor however today I put a brand-new plug on made sure the top part was tight also carburettor off stripped and cleaned filter box had water in it a little cleaned now the spattering is completely gone away Throw out the throttle range but there is still a hesitation at the start and then it will pull straight away like said a little bit and then automatically is power band around about 5 mph however I did have a standard clutch onrear that was a new when I had that fitted it was creep forward around about 10 mph then it would kick in its now got the Delta malossi delta clutch on the rear white springs for shoes and white contra it now seems that it does kind of bog or hesitate with the original it was a little bit better so could anyone kindly tell me what my next options 85 main jet is in I put the Butterfly clip. To central because it was for the second one from the top of the box but that was advised by Ped Parts to put it in the middle what do you think I should do the now lighter rollers ??? I’ve got 4.0 grams in there most important thing the spluttering has gone away and there is no hesitation to which ever mph want to get to it’s just take off any body recall this fix

    Sounds like maybe it's been a fuel issue the whole time.
    Try different clutch springs for the take off splutter.
    If the change of clutch springs doesn't make any difference I would suggest looking at the carb again, possibly the mixture screw can be turned in or out a quarter of a turn.
    It's difficult to diagnose things without riding the bike
