i prosted a thread a week or so ago about my 450 problem. it will run fine for about 15min. but as soon as it gets warmed up it will start blubbering and bogging out real bad. barelay making it more than 5 feet. i hav since changed stator, coil, unplugged kill switch to try and figure out the problem and it still does the same thing. has anyone had this problem at all? and if so is there a fix. it has 25 hard hours on it, with remmapping.

Can you explain the "blubbering and bogging" a little more?

[imoto535]

its like i take off down a straight, then pull out the choke. it sounds lik its not getting enough fuel

[berudd]

have you tried to re-jet it....... oh right, nevermind. ?

just one more problem to add to the 09 450.

CHANGE YOUR SPARK PLUG THANKYOU

just one more problem to add to the 09 450.

Do you own one and it's riddled with many problems?

You have to be kidding me. 1 person on this board says he's having these issues and now it's an "'09 problem"

Absolutely ridiculous.

Maybe its the water temperature sensor.(37870-HN8-A60)

[Lilnuts]

Is the sensor on your sub frame unplugged

[H Bomb]

when you start your bike up do you get any kind of a blinking code on your kil switch?? normal is it just lights up red for about 3 seconds then goes out, if there is a problem with the bike it will blink a series of different codes then you look up in the manual what blink pattern is what. check to see if it is blinking or not that would be good place to start maybe??

Thats what I was thinking.

i have two 09 450s and hav just been swapping parts to try and find the problem. i hav changed plug (thanks anyway) swapped coils, ecm, ive checked all plugs and sealed them with di-electric. im swapping tanks tonight to see if that may be it. it seems to only happen when the motor gets warm. i rode a good hard 15min moto today before it started acting up. and after that it just went down hill from there

it will not throw a code. i unplugged the water tempeture sensor to make sure it would, and it did. but other than that it wont do anything

[H Bomb]

have you checked the sensor on the kill switch for blinking patterns like i posted?? if so is it lighted for 3 seconds as in normal or do you get a blink pattern meaning something is wrong. if so you can look it up in the manual and it will tell you what is wrong

Time for a new muffler baring.

Did you change your gas cap vent?

Did you make any sort of change or check valves just before this started?

[Joe_Jet]

have you reloaded the stock map and checked exhaust for leaks? after that i would check everything having to do with cold start and make sure it's functioning properly when warm.

Now there is an idea. I wonder how long it would take for it to create enough vacuum to starve it of gas?
