hes scared. dont think the wife will let him.....besides let him get one bike done first. that will give him time to figure out how he wants to build the second one up.
the one that comes on it is suposed to have rubber peices that go over the adjustment part of the caps. if not yamabond them. i got 300s in mine and they are close in mods .
i got pro circuits on my trail bike and i like them they seem to pull great thru all the gears. my boy told me to get them cuase they do better with porting than the t6s i had on it before.
