Thanks rocket,we must think alike,i ordered all the seals and bearings from Alpha sports last night,including the kickstarter shaft seal-doh!!!,ahwell.And i got a nos gasket kit off ebay.Unfortunately when i got the bike there were only 2 parts it didnt come with-the rear gaurd and the piston.So i need to get the bore measured first to see what over size it is,then i'll know what piston to get.I might need another cylinder if its on its last oversize,unless they can resleeve it.Thanks for your help.
