I am building a 406ex with a wiseco 11:1 compression with a stg 2 hotcam. It looks difficult to change the cam chain and I am wondering if it is necessary to change the stock cam chain to a crf450 cam chain. If I do not do it what will I lose? Whats the reason for going to an HD cam chain.
Another thing is valves. I was going to buy kibblewhite valve springs because Im going high compression. Should I replace the valves and the valve springs or do I not need to replace either. Is it dumb to just do the valve springs? THANKS
