All things Dwarf discussed here!
We tried a TL1000R 6 years ago because the torque numbers were so impressive. It wasn't very impressive at all in the car. HP wasn't there and it wouldn't keep up with the GSXR cars.
The more I think about it .. The more I think I'll save the V-Twin idea for the golf cart .. It sure would sound good coming out of turn 4 though.
