my atomik reign 150cc has extreme kickback and has had it for ages.I read on here about getting a decomp kit to stop it.Where do i get one from?how much are they?and what is involved in installing it?any info would be great as im totaly frigen sick of nearly breaking my ankle every time i start it.I have set the valves and stuff and i do the tdc thing but still does it.Had bike for about 5 months and it just totaly wrecks the fun.Thanks.
