I went ahead and bought a stock 2008 yz450f. I was reading on this site that the 2006 model had a CDI tuned for: "a more aggressive hit, bottom to mid" than the later yz450f's. Could I direct fit an 06 CDI onto my 08 and gain That change in power?
I would like to keep this bike as Stock as possible but, do some Performance upgrades too. What other power upgrades could I do to this bike Without opening the motor up or buying aftermarket exhaust system?
I ordered an aftermarket Spark Arrestor Screen that I am going to install into the stock muffler so I can ride in the Oregon areas where one is required. Just an FYI about my experience. I was heavily involved with yfz450 quads in the mid 2000's riding all the Oregon dunes and some of the other big Western US dunes. I worked on them constantly, mine and friends, but I want the challenge of two wheels. I plan to ride Dirt and Sand with this bike. Really looking forward to it!! Thanks for any and all suggestions
