gassergod Report post Posted August 11, 2019 So, cylinder, piston and head inserts? Many thanks Quote Share this post Link to post Share on other sites
baldilocks Report post Posted August 11, 2019 Cylinder head is different as the TRS has a bleed valve in the cylinder head. I think piston may fit ? Quote Share this post Link to post Share on other sites

The cylinders are not the same, the cylinder heads are not the same. The base gaskets are not the same, Only some of the pistons and little end bearings are interchangeable. The friction plates in the clutch are the same dimensions, but the steels are not. Very very few parts the same in both motors. 4 Quote Share this post Link to post Share on other sites

So for the sake of conjecture if I wanted to renew the clutch on my TRS Gold I could order the Kevlar plates the new gasgas use theoretically? Quote Share this post Link to post Share on other sites
