so how did each feel on the road? Dyno's only tell part of the story :). how did each feel seat of the pants. I think I would be happy to see 80/90 with stock heads. Do you think I could do it with the 21's?

Stock heads with the TW21 will produce similar results. As one dyno I posted showing my run with mildly ported heads and a 2001 Ultra with no headwork. Both produced mid 80' HP, high 90's TQ. But more important than numbers, the TQ began down low and climbed very nicely.

IMHO, the 95" bike with TW21 cams made for a very streetable, reliable, stump puller of a ride. You can feel the TQ off idle and I was never disappointed on the interstate cruising 80-85 mph.

I can send you clearer, larger copies of the dynos if you want. Shoot me an e-mail: [email protected]
