Wiseco gsx1100e piston i have got measures up the same as the dr250 piston except for the 2mm oversize and 10.25.1 comp Let the rebuild begin!

What year model are the efe pistons from?

Yes sheep those would help!

Hey swiss toni Just building a custom 1984 suzuki dr250 vmx racer going bigbore, flatslide 34mm carb, ported head, custom exhaust, bigger valves etc and trying to find a high comp piston and the gsx1100 uses the same piston rings and 18mm gudgeon pin as the old dr250 so im hoping the piston is the same height except for the high comp raised profile Day job Ducati technician....

Hi all just after some piston dimensions from either a gs1100 or gsx1100 piston with a compression ratio of 10:25.1 Dimensions im after is piston height from bottom of skirt to top of piston and also from bottom of gudgeon pin hole to top of piston Any info appreciated
