Cleyon- You probably have gotten some feed back on this topic, maybe not. I've been running an 09 450txc and still have not solved the carb problems. It is difficult to get the bike to fire up during a ride. Whether it's stopping for a break/breather or stalling in the tight rocky sections, the bike just wont start unless the hot start is turned on. It's been hard to get any good answers to solve this. This is what I've done with so-so answers. I have added a remote hot start that helped out in a huge way. Especially in the tight stuff where the bike stalls out every so often. Zipty racing was tough to deal with (reluctant) and suggested to change the low speed jet to a 42. (stock is 45) This helped for a minute but for whatever reason it still didn't cure the bike from having problems starting/stalling in the tight stuff. I switched back to the stock jet (45) and picked up a R@D racing power bowl 2. This cleaned up the jetting A LOT. The bike really likes the top end / and to be revved higher, working better. The bike is still hard to start after stops on the trail or stalling in the tight stuff. The Suspension: I had Earl Schuler do his thing with it. It was a fair price and is noticeably better than stock. Good luck.
