WR carb removal?

Post by shocker on Mon Apr 18, 2011 9:33 pm

It look's like i've got to take the carb off a WR 250 to clean jets etc.
Has anyone done this, and is it as long winded a job as the owners manual says???

They want tank, seat and side panels off which i can understand, but then go on to say rear subframe, air box, rear shock, exhaust and drain the coolant etc etc too!!!
Two clamps and the throttle cable and the CRF one is in your hand. 10 mins tops!
This is starting to look like a weekend's work - unless someone knows different, and the book is bullshitting??

that sounds about right you shouldn't have to drain the coolant through just take the top up bottle off the sub frame.

you should be able to take out the top sub frame bolt slacken off the 2 bottom ones and pull the whole lot back and down.
this is after you take the rear exhaust off lol!

don't know about the shock through scratch

It dont take as long as you think once you get into it.

I managed to turn a wr400 carb enough to allow removal of the float bowl and jets with the carb still in place..
This was l done at the side of a trail after I took a good dunking a few years back..
May be worth a shot before you start a big strip down..

What a bastard that was!
Due to the alloy frame being in the way, the shock did have to come off like the book said.
I'm carrying a rope from now on, as there'd be no chance of doing all this on a mountain side!

Hopefully worth the hassel though, because the starter and pilot jets were both blocked.
Maybe the stall - hesitate - launch - cycle is now cured Smile

Glad to know you got it sorted but sheeeeeeeet! What a rigmoral just to do the jets! I got twin carbs on my XR and they're a bit of a sod to wangle away from the engine but thankfully dont have to strip half the bike down.

Got the WR back together and thought the problem solved.
Starts instantly, tick's over evenly, dosen't stall as easily and goes like the clappers at high rev's.

The new pain in the arse, is a noticable misfire at lowish rev's - about 1/4 throttle and around 30 mph in top gear is worse. :x
Any movement of the throttle make it go away, but it always comes back
Everything else great, but this is annoying enough to spoil the fun.

Any suggestions please before i seek professional help ????
