Post WR Idle Adjust
Hey,

The idle has been a bit annoying the last few rides. I *think* it's not idling high enough and tends to stall sometimes, mainly when entering a water/mud crossing. Like the ride on the weekend when we went down the steep slippery slope into the mud bath at the bottom (there are a bunch of pics of us going down the hill into the water in the ride report).

It seems to idle fine on the flat but as the front goes down into the water with the clutch in it tends to stall - when only the front wheel is in the water. Hit the starter and it will fire up straight away, so I tend to think the idle is a bit low? It seems to stall when the bike isn't level (ie: front wheel lower).

Other than this the engine runs fine.

I looked through the manual and even had a look online and I can't seem to work out how to adjust it. I thought there'd be a screw type set-up on the carb that needs a turn but the manual doesn't suggest that...

Am I blind/stupid or is it a bit more complex to adjust than just turning a screw?


Cheers

Thumb screw below fuel line. Your fuel line might be covering it.

I meant to add there is a big screw looking thing on the side that has a flat head slot in it, I tried turning it but it felt like it had some resistance and would then turn itself back to where it was - I'd give it a bit of a turn, say 1/4 which didn't seem to change idle speed, take the screw driver out and it would turn back by itself to the original position....

I'll give it another go, I just wasn't sure if that was it dontknow

EDIT: yeah that's the one shultz, I'll give it another go as I wasn't quite sure - still felt like it had some resistance and didn't seem to want to stay turned though....

Sounds like it could be more than idle speed if cuts out when bike is not level.

Andrew on here would be your man for advice.

I had problems with my Honda there for a bit, check adjustment/seal of your fuel screw.
Cleaned your carb lately ?
Not sucking air anywhere ?
Float level ?

Good luck, process of elimination.

Pull sidecover of carb off where cable actuator is, clean and lube everything, you will see where adjuster comes in.

Mine does a similar thing, when going down, but for me, when I'm holding the clutch in and letting it idle for a but it just stalls. I've just learnt to give it a rev when going down hills if my clutch is in. It doesn't happen when I'm engine braking or give it a rev half way

Nope, never
Don't know, hope not 8-)
No idea

I just started it up and turned the (now that I know that it definitely it) idle screw and all seems good, idle was changing, just need to give it a decent turn.

I'll play with it next ride once the engine gets hot, hopefully that resolves it. Not a big deal though just seems to happen (stall) at the wrong times :(
