Engine stumble at cruise.
Howdy folks,
Okay, so I neglected my poor '01 SV650S (stock everything except K&N air filter) for about 8 months, with fuel in it. Finally fired it up a few days ago, and it was only running on 1 cylinder (rear). I figured the old fuel was gummed up, so I:

Idle mixture too lean, check what you set pilot screws to.

Re: Engine stumble at cruise.
The pilot screw is the one originally covered by a plug on some models, right? When I took the carb apart, they were about 3 full turns out from fully seated. Sound reasonable, or give 'em another half turn or so? Most of what I read about them sounds like they're usually about 2.5 or 2.75 turns out when new...

That gave me JUST enough room to drop my socket in and wiggle it around to get it to drop on the plug, then finagle my extension in there, then just barely clear the socket wrench itself. To get it out, I took out the wrench and extension, leaving the socket and plug behind... Then I jammed a piece of 3/8 inch rubber hose down into the socket. It gribbed enough to pull the socket and plug, and was bendy enough to get it all done without removing the radiator. Mind you, there was a LOT of automotive-induced Turret's Syndrome going on. I'm itching to get out of work and go home to try making my idle mixture richer, see if it fixes my problem... -Troy |

Re: Engine stumble at cruise.
The horn is off including it's bracket and the radiator Is completely unbolted but there is no way the hoses are long enough to move it more than an inch, I reckon the hoses where replaced as a botch job a few years bk!!!

Re: Engine stumble at cruise.
If hoses have been shortened it might be different. In that case I'd probably fire in and check the valve clearances too. Good a time as any if you are draining the coolant anyway.
