Strega 0 Posted August 19, 2008 I open the fuel petcock and gas just streams out one of the tubes coming out the bottom of the bike. I'm thinking the float is stuck again (no idea how it hasn't been ridden). Anyone else have any thoughts in this regard before I drop it off at C&D? '07 WR450F Thanks Share this post Link to post Share on other sites
paulmbowers 236 Posted August 19, 2008 you may want to pull the bowl off and clean the float valve- might be a bit o' junk stuck in it. Also, if it's like the FCR on my mighty KTM, there is an o-ring that seals it that disintegrates. Might be the o-ring. fn Share this post Link to post Share on other sites
bikeslut 1 Posted August 19, 2008 the float valve needle probably got a bit of junk in it, as fake name says... mine had the same problem, but my overflow tube was clogged also... so it locked it piston. do you have an in-line fuel filter? Share this post Link to post Share on other sites
dirt dame 561 Posted August 19, 2008 Make sure that the float valve needle isn't damaged and is sealing in the seat. Make sure the float bowl is clean and that the float height is adjusted right. If the floats are defective, they can leak and get filled with fuel and won't let the float valve needle seat. Share this post Link to post Share on other sites

No in line filter, might be something I should look into. Thank you all for the tips, pulling the carb on the 07 WR450 is a PAIN IN THE ASS. You can't get it out without taking the subframe off =\ Share this post Link to post Share on other sites

You can't get it out without taking the subframe off =\ The WR250 is fine cuz the starter is on the front of the motor, unfortunately the starter is on the back on the 450 and there is no room to pull the carb out.

DigDug 0 Posted August 19, 2008 If it hasn't been ridden in a while and has sat with gas in the bowl, I agree with the others - stuck float. When fuel sits it forms a "varnish" on everything inside. Pain in the butt to get off. If you're not going to ride for a while, it's best to drain the carb (there'll be a screw near the bottom of the bowl) and put some fuel stabilizer in the tank. Suck it up, pull the carb out (you really should know how to do it anyways), take the bottom float bowl off and spray the crap out of it (literally) with carb cleaner... Also, while it's apart, like everyone above said, check the seats, etc... Share this post Link to post Share on other sites
Spaugh 1 Posted August 19, 2008 typically you don't need to take the carb out to get the bottom off. Just loosen the clamps on both ends and rotate the carb until you can get the allon bolts out of the bottom. No need to take it all the way out. Share this post Link to post Share on other sites
Ride-Orange 2 Posted August 19, 2008 Anyone else have any thoughts in this regard before I drop it off at C&D? Thanks I agree with the crowd... you need to start learning how to do this stuff rather than spending $75 per hour on service (no C&D on the trailside ) Here are a couple of thoughts if you need help (simple to complicated): Tap on the carb with a screwdriver HANDLE and see if it loosens it up. If not: Pull the tank and pour some laquer thinner down the fuel inlet tube. Bounce the suspension a few times and repeat step 1 above. If not: Get a can of brake cleaner and spray it into the fuel inlet tube as step 2 above (don't forget your eye protection and MAKE SURE YOU DRAIN ALL THIS CRAP OUT BEFORE YOU TRY TO FIRE IT UP!!!). If not: Suck it up and pull that sucker apart (I'm avbailable to help this weekend if you need), yank the bowl off the bottom and soak everything (including pulling and soaking the jets) in laquer thinner, check the needle seat and O-ring for signs of wear, replace (if necessary) and go ride. If not: Call Hammerin Hammon. He's actually a nice guy, lives in North County, has good mechanical skills (as long as you get to him before... say... 11:00 a.m.), and he could use some fuel to bash a motorcycle brand other than KTM... Good luck and call if you need help Share this post Link to post Share on other sites

darylhunter 1 Posted August 20, 2008 Damn Hondas . . . . should have bought a 650L - oh wait, they're Honda's too If all the good suggestions above don't work, you might try squirting a bit of carb cleaner back up the vent tube where the gas is coming from. That might loosen up and flush what ever is making the needle stick back into the bowl. Only a short term solution though because if it's in the bowl, it's likely to happen again or get stuck in one of the jets or other orifices. Share this post Link to post Share on other sites

Get a bike with F.I. then you can spend 300.00$ -600.00$ every time the check engine light comes on. While the FN. dealer changes a 10.00$ censor Craig.
