Loboboy, I'm curious what is different about the front of yours that it can use the T-pin. I have no idea if mine could or not, I never had a whole lot of interest in it. Mine has the adjustable mounting points on the front and I haven't even messed with those yet. What is different about the CR link? I have the no link, which I think is close to the same set-up as your frame.
As far as motors go, mine is in the low to mid 70s and docile as hell down low. I run 16/39 gears if that tells you anything, the powervalves give it alot more down low than I really even need. Having the bike to run the motor is key.
