yes, its a good running build but there is still more in it without opening the motor.....an fci and dynatek with a custom curve will give u close to 600 more rpm to play with above the 60 hp markI recognize Tim's run he has posted. It is my quad! Not sure if you guys are splitting hairs or not but all I can tell you is that to me, it ran like a raped ape! I'm not in to the straight line type drag racing thing as some are(although I am always up for a good drag race). I asked him to build me a reliable trail (MX/XC) quad that I could run on pump gas anywhere in the world. For a stock bore and an 11:1 piston, I was more than pleased with the results.
so the pro design is 3 inches all the way thru??? if so and the monster tapers down to 2.5 inches how is it lettin more air flow??I took some pictures to compare the billet adapters against eachother. As you can tell from the pictures both openings are exactly the same. Both units start at 3.5" and taper down to the 2.5" with the biggest difference being the Monster has a longer and a bit smoother taper but not by much.
I even weighed them out for you guys
