07 450er revvin problem

[hunter61]

my 450er is idling and starting fine and you can snap on it and its fine. but when you hold it, it dies! no idea why? could it be jetting?

is this something that all of a sudden started happening??, if it ran fine before then its not jetting, dirty carb or air filter

[hrc450er]

throttle sensor ?

[hunter61]

could it be that sensor i took it out?

[hunter61]

cant be sensor...... could it be a stuck float or dirty carb???

unless you changed your air box and air boot then it could be jetting, but if you put the same parts back in then jetting shouldnt be an issue!

if you used the same style intake parts then it sounds like you have a air leak
go through your whole intake system and make sure everthing is clean tight and check the underside of the boot to make sure its seated properly

checked for lesks no leaks that i can see or find...... i can blurp it rev limiter but wont hold constant throttle.....put same style boot and everything back on it???
