This is copied and pasted from another forum. This guy instaled a stroker kit on his bike along with alot of other mods as well.
I did play around with a custom V-Twin probably a S&S powered Big Dog on the I 95 and I had no problem staying with and accelerating quicker from 70 to 90+ or maybe 100+ while passing on the intersatate. He was always attempting to pass me and always behind me until I made my exit when he blew by still accelerating.
Throttle response is also a dramatic change--the rpms hit harder similar to the race bike--but a new clutch is definitely needed--the increased torque is causing slippage anytime you hammer the throttlle. The Barnett kit had about 22k miles --I did not change it because I saw no excessive wear.
This bike has a pile of money in it from appearence, and it's not all in the motor. There was also headwork done to this bike as well.
