just got the thing running aninal again (After posting a disappointing
122rwhp at the VMOA Daytona Dyno shoot out) yesterday. thing was pulling like when I first got her back from John Ganey and he presented the ~190 rwhp sheet.

This morning I completely lost 5th gear...ugh
Ironic thing was i wasnt even hitting it hard at the time...It was very very windy so Im thinking there was a good amount of torque on the gears.

all entail. At least it happened right when I am expecting my tax refunsd. My
plan was to dismantle and convert to EFI this month anyway and now it looks like
I have more work to do.

have learned? btw, The bike has been converted to chain drive.
