* gen i cam combo*

[Petey Wheatstraw]

To the Experienced builder: How much cam is too much cam for the built stock bore engines? Bike makes 175 rwhp rite now w/2intakes,so how much REALLY is that at the crank? Has anyone ever heard of a stock bore motor with 425/425's? My tuner suggested the 425's,but im thinking that its overkill 4 stock bore,and not too streetable.But hes sayin another 10-15hp.Any truth to that,or is it just BS? Any help would be greatly appreciated.

15hp for a cam swap is bs

First off the 425's are not drop in cams.
They require the guides to be pressed down, as well a valve job.
Also for a cam that big, you would want a big valve ported head.

They really for a stock bore motor are too big!
