WR250R clutch wire?

Hello , the other day i was washing my bike when i noticed that the was a weird wire type thing that was sticking out of the clutch level near the cable. I pushed it in and it poped back out as soon as i pulled in the clutch level. does anybody know what it is or how to fix it? thanks!

It's the connection for the foofoo valve.

The foofoo valve acts like a supercharger and boost power.

It's why it's much more powerful than the KLR as that doesn't have one.

is it bad if i ride it w/out getting the problem fixed?

You're best fixing it or you'll burn out the foofoo valve and your bike will end up slower than an XR75 !

crap i rode 250 miles with it unfixed >.< does it control the exup valve flap?

Sounds like the switch that won't let the starter motor work unless you pull the clutch lever in while the bike is in gear.

thats what i was thinking too but i ran some tests and it started up either way kickstand was up

Nope, it's the foofoo valve. Unless it controls the pitch governor.

My foofoo valve went out 500 miles after that wire popped out. Had to completely tear down the motor and rebuild it with a new bottom end.

ive still got a warranty on it im going to have the dealer take a look. thanks for scaring me!

Oh, yes.
The foofoo valve and the muffler bearings.
Classics. :)

hopefully it'll give me an incentive on buying an FMF system but is it worth the upgrade $$ wise ?

I'd have to say it is. Unplug that thing and let er rip!

i just tucked my up behind the head light with a zip tie and all good. better with out it.

Just pull the wires out and splice them together. It will open up the timing limiter and give you about 5 more hp.

LMAO!! This thread rocks, great info!

Just don't go into the the dealer with a confused innocent look on your face and ask, " Hey could you guys take a look at my bike and let me know how much it would cost to replace my Foofoo Valve?" You'll see an evil grin appear on their faces as they discuss how much they can get away with charging you for a good old fashioned American "BEND OVER".

The clutch switch is the opposite of the kickstand switch in terms of how it works. If the clutch switch is unplugged from the perch, the bike will start clutch pulled in or not. I was messing with it when my neutral switch went. It's probably popping out because you have to get the little clip on the switch lined up with the groove on your clutch perch. It will click into place and shouldn't come out then.





foofoo valve. That is one silly sounding part.
