This is my second set of stage 2 hot cams . My first set are in a stock DRZ 400 motor which I run with a MRD Z Pro full exhaust system and a larger than stock 40 mm CVK carberator . That motor has been running great for 24,000 miles now . This newest set of stage 2 cams is going into a big bore 434 build I expect equal or better results from them . The stage 2 cams work with stock valves and springs . They increase the power most from 4500 rpm all the way to redline . Which is 10,500 rpm in the DRZ 400 . Get some . You'll love them .
