Hi are the 350 199 engine and exhaust compatible with a Sherpa T 191 frame, how many of the parts are interchangeable.

The 199 exhaust has a higher rise over the head than the 191 pipe so it will sit a lot closer to the underside of the tank. It also bolts directly to the cylinder so you'd need to remove the manifold from the 191 cylinder. You might also find the outlet doesn't match the inlet of the rear silencer in respect of tube diameters but if so that can be sorted by welding the correct size tube to either one.  You're not really going to know the answer to your question completely without trying it

For interchanging parts it's difficult to give a precise answer as there are differences. Not many engine parts are directly compatible, head and barrel can be changed together but not individually as 199 uses a head gasket, 191 doesn't. Gearbox internals are different, crank probably looks the same but the 191 has a single bearing on the clutch side, the 199 might be a double, can't remember.  Forks and wheels are the same

Hi Woody, thank you so much for sharing your knowledge, that's a great help and I will investigate further.
