if they are making 80 to 120 hp then it is far from stock.. I own a dyno and hurt peoples feelings with it on a regular basis.. Figure a twin cam 88ci engine with pipes, intake and a tuner makes on average 65 to 70hp. Thats at the top end, useable is around 50hp.






I have been to a lot of bike nights and rallies that have had dynos on sight and have seen a lot of sad looking faces when they see the results
