I have a 05 yfz 450. it was running perfect until I blew the muffler mount and created a hole in the exhaust... this is when the problem started.. I replaced the exhaust but since it will not idle good and it tries to die when I open the throttle past half way. but 1/4 throttle to 1/2 throttle it revs good.
Brand new carb rebuild and clean
new cdi
new coil
new voltage regulator
new relay by battery box
TPS deleted
after all this I still have the same issue..
