Well.... if the boy would get off the damn thing for a few minutes I could give you my impressions ! Hahaha ! Actually I stole it away from him for a brief ride and it's not bad. Not YET quite as quick as his old mans Bullet now !...
But it ain't bad. I also snuck in a quick compression test of the thing in the middle of the night while the boy was sleeping and the motor was cold..
They build a LOT of compression ... a bit over 200 PSI .... with those short duration cams and that big slug in there . And that's even with the auto decomp still on that cam I believe. Ummmmm..... has me wondering about those early complaints of "pinging" with the GT's. Yeah, a bit of a rattle if it is slightly lugged. Anyways... he's running Super now.
