2005 yzf450 issues


Recommended Posts

I am working on a 2005 yzf450. In the midrange it runs terrible. It runs good just cruising slow and wide open but if held steady in the midrange, it spits and sputters, and almost like it misses. You turn on the choke and it gets worse. The plug is perfect looking. I've gone through the carb numerous times so I know that is good and clean. Could this be an electrical issue such as a bad tps?

That is almost exactly what I angling through right now. It has been at the dealer for two weeks and they have no clue. I even had the carb off at least 15 times trying everything. Never a single issue before. Nothing. I am baffled too

Both of you guys......what kind of airbox do you have? If you have the stock airbox, and run with the lid on.......take the lid off and see if it runs any different.

Also.......but of you list your current modifications, and jetting.
