I did the same port job on Jay's moby as I did the first time I ported mine - more for good overall performance.
If you got some lower bars and a lower seat to get you out of the wind it would give you a lot more speed and midrange acceleration.
Thanks for the new rings it is great to have my fast bike ready
no more scootie puff for me!
Yeah the rt 28 to boston ride is a blast but I wouldnt want to do it on a slow bike.
