Dflynn926 Posted April 9, 2017 Author Report Share Posted April 9, 2017 Dual fuel valve? Make sure you're getting fuel to both carbs. Might have a partial clog in the line. I'll check that. Im going to take my buddy's right carb and rejet it to my bike and see if that fixes it. After checking fuel line. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 9, 2017 Report Share Posted April 9, 2017 I was able to get carb cleaner through it though? When I take it off again ill try cleaning it out again Did you take it off and look through it? I had a tiny piece of trash in there once on my yz250's pilot jet. I was only able to get it to idle with the choke since it bypasses the pilot somewhat. I stuck a needle or small paper clip to clean the blockage out. Before i swapped out all sorts of electrics etc and all it was was a free fix. Quote Link to comment Share on other sites More sharing options...

Before i swapped out all sorts of electrics etc and all it was was a free fix. I was able to see through it, but at this point I'll try again, since it'll be off when I swap carbs. I may end up getting new jets, that are slightly larger. Since I'm running 290 mains Quote Link to comment Share on other sites More sharing options...

RIPPIN' IT UP Posted April 9, 2017 Report Share Posted April 9, 2017 I'm on my third set, just to be sure lolOkay, I had mine do a similar thing but only at idle & when I reved it up, it done that back fire blowing thing out the exhaust. Water had gotten in when washing & blocked the pilot jet. You said yours was clean, make sure the venturi isn't blocked or restricted either. I cleared it by revving it up & sticking my hand over the right side carby, sucking the water through.

Dflynn926 Posted April 10, 2017 Author Report Share Posted April 10, 2017 I didn't read everything, what's the compression at? It is at 104psi. Same as when I got the bike last year. I don't have a camera Quote Link to comment Share on other sites More sharing options...
Dflynn926 Posted April 10, 2017 Author Report Share Posted April 10, 2017 I'm getting spark, and plug has been wet so id assume I'm getting fuel. I ran it for a bit and was getting a wet exhaust. I pulled my expansion pipe and there was no build up of fuel in there Quote Link to comment Share on other sites More sharing options...
