MEGABOMB DYNO TEST-before and after
#12
What mods were done to the bike used on the dyno?
How many runs were performed?
Not changing anything, larger diameter head pipe will produce more power it's a known fact. All off road pipes offered are larger diameter.

I'm not sure that just going larger on the headpipe produces more power is a fact. Obviously you reach a point of diminishing returns and at some point the pipe is too large to scavenge effectively.
I recall reading, maybe here or on ADV, that when Bill Blue was dyno testing his 351 kit, it made the most power with the stock headtube and aftermarket slip-on, and slightly less with the powerbomb and same slip-on.

I agree a largerheadpipe increases power IF the header is the limiing factor. What this dyno tells me is that the head and valvetrain on this motor are the limiting factor. The next step is a valve enlargement and clean inner surfacing then retest. It would just as easily be the camshafts that are the limiting factor.
On a stock or even jetted klx, the header is NOT the limiting factor

I agree the cams and intake are also probable cause.

I think it was also tested by other members that the aftermarket carbs (tm34 or tm36-68) don't improve power only throttle response
