Re: overheating on r50
How are you riding when when it overheats? Are you stopped in traffic or travelling? Are you sure it is overheating? What are the indications of this overheating?

Re: overheating on r50
Hi Jorge
If you have already checked all the points that you have mentioned, only other 2 points come to mind which can cause your R50 to overheat.
1. Centrifugal advance/retard governor is worn and no longer works properly causing the ignition to be too advanced. You can check this with a stroboscope.
2. Carburettors are set too lean and/or you have the incorrect main jet/air filter combination
Best regards,
Mark

Re: overheating on r50
I think Mark is right, your flywheel(?){it was to make the ignition towards to "F"} has a little leave spring to make sure that the ignition timing doesn"t get to much forward. somestimes it breaks, and so you get a Ignition to much forward(overheating,less accelaration and so on)
