KR-1S.co.uk Forum

hi everybody,bit of help please i have recently had my kr1s of the road because the rh barrel cracked leading to destroying to the water jacket,not repairble so i brought a complete kr1 which is a project in its self mainly for the engine,ive had the engine in the bike and its runs good with bags of power! however the power valves was seized on the left barrel,i tried lubeing and gently loosening but ended up snaping them both and loosing 1 of the linkages! i no.ive still not managed to get the head off,didnt want to risk breaking the other 2 so ive left it for now,what i want to no is can i use my 1s power valves in kr1?im hoping to give the whole engine a re-furb with some new gaskets and seals when ive got a bit of money to throw at her but just curious on what am going to need thanks alot danny

Yeah, they'll fit Danny.
They do have a larger opening than the KR1 though and will leave a slight step wher the ports line up, but this should't noticably effect performance.

thanks Scottakr for the quick reply im glad to hear that!least thats 1 less thing for the list cheers danny
