Clucth in at idle and engine reving out of control?

[saolom]

I'm having problems trying to stay idle at traffic lights etc..

Everytime I try and clutch in, it revs out of control? No air leak because when I choke the engine it dies, the idle adjustment screw is reasonable 1.5 turns out, clucth cable has been greased, no boost bottle or nos. Very anoying!

Any help would be fantastic! this engine has been running for 6months hard and with 2k km;s +

When you turn your idle screw in or out, does it effect the engine rpm? I'm wondering if your cable is too tight. Also, when you pull in your clutch, the cable moves. Is it pushing against your throttle and moving the cable, causing the extra rpm?
That's all I can think of.

[saolom]

yes it revs higher and lower when I adjust the idle, have double checked the cables and are all fine.

cheers toytime!

I would still check for an air leak. If you have a rich carb setting, and an air leak you will have the symptoms described, including the ability to kill it with the choke.

Does the idle screw change it at all? I had that problem and I had to shorten the housing on my throttle cable to get enough slack.

[Bikeguy Joe]

The idle speed screw will work if the cable has some slack.

I'll check for the air leak by using inscents so see how I go. The idle stays idle and does not roll only if I pull the cluctch in 5-6mm but anymore and it will start to go.

Thanks guy will check now.

[saolom]

yes the engine is good. No air leak.

I can't seem to find an answer yet?

Hope someone else can.

thanks in advance!

Incense? to find an air leak?

Best way to find an air leak is to spray Carb Cleaner around the area you are checking but not the air filter. The engine will slow down or die when the carb cleaner hits the air leak.

Yeah I used both inscents and carb cleaner. no changes
