Have you made any changes ????? or is it still stock ???

 

I had the same thing happen. Turned out to be a pinched fuel tank vent line. It had about 6# of clay thrown up on top of the tank!

 

vforcer - engine-wise, it is still stock, module on order, would like to sort out this little stumble before it gets here. trx450 - thanks, I will check vent lines, they do vent into the subframe, do they not? I guess just being pinched could restrict them quite a bit. I did post more info in another post of similar name, this blank one was posted by accident, kinda new to this.

 

Mine did that I tuck the gas tank vent apart and put it back together the way I think it would be. Works fine now..

Watch your sliders in your carbs if it dies after a lot of use then it's time for carb work.
