DOES ANYONE KNOW IF THERE IS A LIGHTER FLYWHEEL AVAILABLE FOR THE GS ? OR HAS ANYONE TRIED MACHINING THEIRS TO REDUCE WEIGHT, IMPROVE ACCELERATION ETC ETC ?

ANY ADVICE WOULD BE GREATLY APPRECIATED. :dunno:

your capslock seems to be broken

i havent heard of a racing flywheel or anything like that.  just do the exhaust and rejet it.  its not impressive on the power increase but it does make it smoother.

What flywheel?

Well people remove that counterbalancer and balance the crank ... Ask Bob Broussard. Evidently in a narrow spread of revs ... like 7-9K its quite smooth ... now what else is there ... this is a damn GS ...  :lol:  ... otherwise it spins up insanely quick ...
Cool.
