I am very happy with the cam I installed. Would I have done a different cam? maybe. It would be nice to have a bit more top end power, which is generally where this motor really lacks, BUT I also love that the particular cam I used needs no other supporting upgrades to work, and it definitely give a bit of a bump in the power department. It takes the Hawk's existing power curve and gives it "more" within that same RPM range, and maybe just a tiny but more up top, but not a ton.
So, if you want more top end, a different cam profile will definitely be a better choice. If you want more grunt, then a ported head, advanced timing key, exhaust, and this cam will up your tractor factor a pleasurable amount.
They big thing to try and be is realistic though, even if I took this engine from about 15hp stock to 20ish+ as it sits, it' still only 20hp pushing a 300lb bike with large diameter wheels and off road bike aerodynamics (not that great). Would I do it all again though? absolutely. I love tinkering around with these cheap bikes.
