the time came to check my top-end, so I took off the cylinder and piston.
the last one was a Wossner B
the cylinder was measured by an automatic Zeiss machine. here are the results:
what should be the propper piston diameter?
the manual says:
cylinder-to-piston clearance: 0,020 - 0,045 mm; limit = 0,1 mm
In my opinion a Wossner C (94,98mm) would fit and it would give a clearance of 0,035-0,043 according to my calculations... so that`s close to the upper service limit... what is your opinion?
big thanks for any suggestions. I have to order the pistion ASAP because we have an round #2 of EXTREME ENDURO Tournament soon, and so far I am 5 of 32 and plan to hit the podium next time
