2002 YZ426 fuel screw LEAK
Posted September 30, 2010 - 06:14 PM
I looked into the hole, and no extra parts in there. Installed the new setup and it's still dripping. Installed the new spring, washer and oring on my Ziptie Screw and same problem.
I dropped the bowl and the gasket is good.
Just for giggles I put Teflon tape on the screw threads and it still leaked. I'm not sure this is a good idea. ??
I haven't set the float height, and I need to look for a crack or leak in the bowl that leaks into the cavity the screw goes in.
It drips about 1 drop every 4 seconds.
Any quick ideas, I'm sure I'm overlooking something.
I bought the bike with the leak, and a missing o-ring, thinking it would be an easy fix.
The bike runs great, so I don't think the level of the fuel is as high as the small hole where it's really close to the slide.

BTW get rid of that teflon tape on the fuel screw before it ends up in your idle circut.

I dropped the bowl again, and the bowl held fuel just fine, nuts no smoking gun.
I got all the teflon tape out, and I swapped out the rubber gasket for the bowl, now no more leak, other one looks fine, but it's not.
I triple checked for cracks, and also checked the swivel.
You guys rock!!
It did take me 30 kicks to get it started,lol. I was to careful not to flood it, but you still need some gas for the beast to start. Once I got it running I settled the Fuel screw to 1 1/2 turns out and set the idle, now she starts easy, time to get her out in the desert for some plug chops.
