Rotax Gearing

[1967 karter]

I will be running a 125 Rotax engined kart (sometime) this year.

It is fitted with a 19 tooth engine sprocket and I am wondering what range of rear sprockets is required ?

I assume that most people run split rear sprockets, can anyone advise where they are available from.
Thanks,

Adrian

I used 18/29 for Teeside, Landow and Rowrah and 20/29 for Strubby.
Try Dave at Startline for sprockets.
