I just got a stock 02 crf 450 and I was wondering if there are any thing that I can do to make it run the best. Jetting?(sea level) Also are the stock pistons know for being noisy, or should I just replace the piston? Any sugustions would be great, as I am new to the hondas, past bike was a yamaha wr400. anything extra needed for supermoto conversion becides the usual?
thanks

go one up on both jets, forget about the piston it's fine.

Does it have a Pro moto billet end cap with spark arrester?
If it does see if it is blocked with muffler packing. It happened
to my 450 and it ran like shit.
