I don't think it was this bad before my rebuild so I am going to try and move the kicktart up a couple of splines before i try anything more adventourous 
Good advice on the marking the gap, thanks. What other kickstarts would be worth trying? Do you mean kickstarts from other models of scooters?stokky wrote:Coaster option is a good one.
But I also find the splines on each kickstart can be different, so swapping kickstarts around can sometimes help resolve.
(Note before removing kickstart, always mark in pencil the gap onto the end of kickstart shaft (so you can always get back into same position)
Thats the easiest way to do it.Just remove the kickstart and move it anti-clockwise a couple of splines.Push the kickstart on to the first part of the splines and push down until the kickstart is under the bump stop on the case,then push it all the way home.As long as the teeth dont catch on first gear,your good to go.alanscottj wrote:More work, time, money!coaster wrote:It's a well known problem with the GP as the kickstart it not adjustable.
