1997 yamaha won't idle/run good when hot

[Bigman12]

Hi, I have a 1997 yamaha warrior I just put in new jets ( stock size ) flot needle and seat in my bike due to gas comeing out of the over flow. Before the gas started leaking the bike ran fine now when it gets hot it won't idle and bog at low Rpm's. I also didnt touch the idle or air screw when put the new parts in, any help would be helpful Thanks

Did you adjust your float level.

 

[Bigman12]

No I didn't

Check it. Who's jets did you install? Mikuni, moose, other?

 

[Bigman12]

I'm not sure but Im pretty sure it wasn't minuki

 

[Bigman12]

Im thinking it was moose

Well... I've had good luck with the moose kits. Used one on my friends warrior, except main jet for the pipe. I've used them on countless other bikes, too, and have never had a problem. Start with the float level and go from there. You seldom have to replace jets with new, unless they are seriously gummed up, and appear to have "etching" from todays fuels or from varnish/old gas. If the float level doesn't correct it, clean, and blow out with compressed air, your old jets and reinstall them. Did you look to make sure the new jets where the correct size? 42.5 pilot, 145 main? If you had fuel coming from the overflow, then the float, needle, or seat is the likely prob, in that area.

That's what I did put the float needle and seat in I only put the new jets because they came in the kit, and I look at the numbers and the old ones were the same size as the new, what do you mean by the float valve
