Thank you Thierry. I have two non reed valve Beta Gs 250s, but just wondered if the reed valve engine timing was different.

To me it seems that all the 250 cc engines from this period have between 1,8 and 2,2mm, that's the case for the Rotax and the Hiro for instance. I think that it should be the same for the BETA.

Thanks for the translation Thierry, I can't believe someone does not have this information.

Quelles est l'avance à l'allumage pour une BETA GS 250 à clapets?, 2,2mm?

Firstly apolagies for using English.
My question is, could someone tell me what is the ignition timing for a 1981 reed valve Beta GS 250 ?
Is it the same as the 77/78 engines at 2.2mm before TDC.

Thanks.
