66 plate gt125r idling high when warm
« on: April 25, 2019, 10:45:42 PM »

Has geniune air filter, has had aftermarket silencer fitted, and rejected

Bike starts ok, runs well hits 75mph but when warm idles at 3000rpm, tried twisting thumb screw but solid any tips to free off in carb, can't find parts in catalogue.

Any help would be great fully received

Rejetted to what?

Unbolt the idle adjuster from the carb and engine block. Warm the thread on the end up. You might need some vice grips to work the thread backwards and forwards to release it (do this on the cable side, not the thread itself) but it will go eventually. Grease the thread up after cleaning it and put it back on the bike. Set the idle to 1400 rpm after warming up. You should be warming the bike up on choke if its cold.
