XTZ660 -91 Engine in a TT600 -83 frame?
 

Hi.
I'm new to this forum, but I have read most of the topics with great interest. I really hope it's anyone here who knows if and how on the topic?
The engine in my -83 TT600 is getting pretty smoke-blowin' and lazy on low rev, and I have heard a lot of good things about those 660 engines, is it possible to put an -91 660 engine in my TT? If so, what need to be done? By Murphy's law nothing is simple, but then again, they say nothing is impossible for a good mechanic, it only takes more time...
Answers is highly appreciated

I think that it will be VERY difficult to find the place for the liquid-cooled 5-Valve 660 inside the TT frame ...and then you will have to find the place for radiator...

From what you write (smoke, low rev performance) seems a piston rings failure/ valve guides failure...surely much more easier and cheaper to fix !
