I am having my 1996 Ultra 80ci EVO rebuilt with Zippers performance kit. The kit includes new pistons, new PCM, stage 2 head work, cam and upgrade the EFI. They guaranty 80 HP and 90+ tq. Has anyone have any expience with Zippers or their products.

 

No personal experience, but they have been around for a long time. 80/90 numbers should make for a real nice bike.

 

that should restore it's original zip and then some
