Derbi Motorcycles - Recent Questions, Troubleshooting & Support

I know you said you cleaned the carb, but maybe something got in the carb when trying to start the bike. Because it sure sounds like you have a clogged pilot jet.

Float height is not related to time. This is a very technical area (carb adjustment) best left to the pros who have the skills, knowledge and equally important, the measurement tools to properly adjust a carb. Time is an entirely different thing.

Fixya is unable to source parts.

Hello! How did you solve it?

Hi mate if the cable had not been seated into the speedo drive correctely it will give you intermittent spinning.
Take the cable off at the speedo drive at the wheel and repeat the lifting spinning of the wheel and watch the "actua"l speedo drive spin.
If that intermittent pull the wheel off and inpsect the speedo drive itself.
Its a basic unit so should be an easy fix.
Other wise replace it if you dont think you can fix it.
Hope this helps
