Royal Enfield Classic 350 Hitchcocks Prerformance Camshaft any good?

We ride the Classic 350 with the Hitchcocks Performance Camshaft now fitted and along with the DNA Air filter and stage 2 airbox mods, De Cat, free er flow tail pipe, and Fuel X Lite The tappets were noisy as it turned out they not been adjusted correctly - I think because the TDC tool was really tight to use and I think it was not seated correctly and so while the tappets were probably ok and i had unknowingly re set them slack! I re did them next day and the motor is real quiet now with less popping on over run and it feels like it is now pulling a tiny bit even more!
