Piston to cylinder clearance specifications needed.

PowerFiend · Aug 23, 2004

Hi,
Does anyone have the recommended piston to cylinder clearances? I'm specifically interested in the late models with 100mm pistons. The service guide says 100-99.88mm, but 100mm is unrealistic for a piston if the cylinder is supposed to be 100mm. It also doesn't factor cylinder sizing variations.

thanks for any help.

Hi Powerfiend,
For OEM .0025" - .003"

Hope this helps.
Sincerely,
Dale

Thanks Dale.

Oops, almost overlooked the OEM. How about for a forged piston like the Wossners? :?:

It really depends upon the exact piston alloy and final piston shape.
Best to start with piston manufacturers guidelines and test from there.

FYI:
Some of the "True Forged" 97mm pistons we use require .006" piston / cylinder clearance.

However, based on prior experience you should be good with a minimum piston / cylinder clearance of .0025 with said piston.

Sincerely,
Dale
