i know this is a common problem, but this is getting ridiculous. my 2nd valve float just busted on my 98 wr400 in 4 months!. I'm trying to get keihin to replace it (not holding breath). any suggestions for a stronger part? i remember hearing something about them updating it. I'm seriously thinking about going with a different carb. to get back on the road i guess i'll just order another along with the seal. best options for oem parts? AAAAAARRRRRGGGHHH!
