Hi David
The sprockets will likely have to come from a Lav supplier (OCT, Wagner etc) but you can save on post and buy a good quality chain (I use o-ring) from any local bike shop.
Be careful fitting the front sprocket, some are a tight fit and bashing it onto the countershaft splines can push the stub-shaft into the gearbox a bit and give you a motor strip job. I heated mine up and carefully tapped around and around with a light hammer, it barely started on the splines from cold.

the main problem with the tight front sprocket is that their spline edges are too sharp
on the male spline there is a slight radius at the root of the spline
on the sprocket female spline the very edges of the spline are too sharp
I use a pencil grinder to relieve that edge, does not take much, 5 secs per edge roughly, is just a quick clean up
then sprocket is a light tap fit
I buy all my front sprockets from Wolfgang but I believe the majority of the front sprockets available are all made at the same manufacturer in Europe

Hi, David.
the case with a file or dremel before.
Ernesto
An o-ring chain (530) might scratch on the inner housing. Modify
the case with a file or dremel before.

If you are using the bike for commuting or riding all weathers an O ring makes
perfect sense.
Otherwise go for a non O ring good quality such as iwis, google for local distributor.
The ref is M106SL.
It is easier to fit and will give a much better ride.

Looked at the spares site mentioned above and lots of stuff including sprockets.

Hi David - I 've got a 38 tooth Grimeca type (5 hole) sprocket - came with my SFC for some reason - it looks hardly used - ?10 plus postage if you want it. Makes high speed cruising a bit nicer! - Regards - Phil

I'll find out postage cost to Sweden - then I'll send you a private message on this forum, then you can pay with "paypal" - it's very easy - Regards - Phil
