vectradam Posted August 10, 2019 Report Share Posted August 10, 2019 Hi are GAS GAS and TRS engines the same, as on the S3 website they say that some engine parts fit both bikes thanks Quote Link to comment Share on other sites More sharing options...
lineaway Posted August 10, 2019 Report Share Posted August 10, 2019 No. Similar designs yes. 5 speed vs 6 speed trans. Quote Link to comment Share on other sites More sharing options...
huski Posted August 10, 2019 Report Share Posted August 10, 2019 Top end is the same but that's all Quote Link to comment Share on other sites More sharing options...
gassergod Posted August 11, 2019 Report Share Posted August 11, 2019 So, cylinder, piston and head inserts? Many thanks Quote Link to comment Share on other sites More sharing options...
baldilocks Posted August 11, 2019 Report Share 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 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

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?
