    How to set CAM TIMING with RR Cam???

    Should it be retarded or advanced? What is a good compression number i should be looking for? Is it different then timing it with a stock cam?? Stage 3 + engine

    the rotax cam is made to be run straight up ..you can play with it it will give you more up top or more down low..you will loose some compression..you are supposed to run a thinner head gasket..and the rotax cam tensioner..i shaved my head 5 thou...was reccomended i shave it 10...but i rec ride so wanted some insurance..if i ever need to cut it agin i want to be able to..

    i only see about 115..but on a stock bottom end at 150 hours..so i am a little worn..ill be getting the parts together so i cam possibly do it dec jan when it is cold here..feb march we start to ride regularly again..
