[QUOTE="Queensland Ken, post: 1339724, member: 4399"] What is the RPM when you first start up the bike ? The bike always starts on fast / cold idle, ie the Fast Speed Idle Circuit. If not someone has played around with the adjuster or has disabled it. As the wax motor heats up, via the 2 small coolant pipes, it blocks off the 4 fast speed idle valves ( pushes them in) and the RPM drops back to the normal running hot RPM. It is the 4 air valves that govern and drop the RPM back to a normal hot idle RPM. [MEDIA=youtube]c70sIeZ9lwg[/MEDIA] The transition between fast/cold idle to warm/normal idle. I'm activating the plate on #1 TB. If the bike doesn't readily drop the RPM as it heats up, most likely the small hoses are blocked up with crud.

Cold / fast idle can only be adjusted while the motor is COLD. As far as I noticed, the coolant pipes only go on one way. Bottom hose of the wax motor to the radiator, wax motor top inlet pipe adjacent to / near the thermostat. [/QUOTE]
