300 sefr top end
« on: November 20, 2020, 02:16:39 PM »
Hi I plan to do the top end this winter i bought the bike used and it has 110 hours now.  I have the piston kit ,and required gaskets to do the job but should i change anything else in the top end such as  the Cam chain ,tensioner ,chain tensioner sliders , valves etc? or just check them for excessive wear and go from there? Ps is there any suprizes to expect as this will be my first time rebuilding a sherco 4t.
