Franz and Grubb Engine
Triumph 750 twin cast piston kit
Regular price $84.95
What if the piston is too small?
Sometimes the machine shop will not be able to clean up the bore for your piston size. This is because a + .020" piston will only take .010" off per side, and the cylinder may also be worn or have a taper. You can exchange any piston set from our shop with another size should you ever discover this is the case, as long as the rings have not been file fit or pistons modified. No problem.
We include installation sheets.
Instead of the typical and lame "refer to your manual" we include our own installation notes written by an experienced engine builder which will help both the installer and/or the machinist doing the work. These include recommended clearances and suggested ring gaps that have been successfully used at our shop on street and racing engines.
