i did a search but found only a few usefull answers....can anyone else comment on this? are there any problems after instalation of the flywheel?

 

I'm surprised Jeff has yet to chime in here with his salse pitch

Most people who have them like them.

 

whats is a flywheel? I never knew what it was...

 

I like mine. No real driveabilty issues with the Findanza, just takes a few miles to get used to it.
To me it feels similar to when I switch to light weight wheels at the track, not as much, but the same type of feel in acceleration. The gains are felt mostly in 1st gear and a little in 2nd. Can't tell the difference in 3rd, 4th or 5th.
