Never heard of any engine problems as far as longevity goes, biggest issues have been starting related.
Sherco sent out a kit over here to all the owners that included a new kickstart, ignition/coil, hot start kit for the carb & different camshaft. I was told 1 of the problems with them not starting hot was insufficent exhaust valve clearance which kept the valves open when hot. Shouldn't be too hard to find out if it's been done
The former importer here in NZ put a oko flatslide on 1 & found major improvements in carb performance
The 05 3.2s have a very manageable power delivery which is far better for the average rider than the current model
Not much difference cycle parts wise to the 2 stroke, really only frame with removalable front spars, smaller tank & maybe airbox, rear guard being different
Give it a try & see if you like it.
I tried 1 when they first came out & reckoned if as was rumoured at the time that only 4 strokes were going to be available that I would have been able to switch without too much problem
Hope that helps out
