I have been reading up on building my trx450 engine, It is an 06 engine. I came across some stuff online and was told by a couple of engine builders, that most of the GNCC pros preferred the 05 motor over the 06-07. It mentioned the 05 revving slower and something about the stoke being different.
But i thought a lighter or heavier flywheel would get your revs up quicker or a weighted one would remedy the quick rev if you didnt like it,
I had just never heard this or read it anywhere I was asking hasd anyone else heard this information
