Here for sale a Siebenrock Kit which takes your 800cc 2 valves Bmw to 1000cc without any modification of the heads/carbs.
I originally bought the kit new for my bmw r80/7 cafe racer, however I’ve never been able to carry on with the project leaving the kit collecting dust in the cupboard.
The kit is suitable for an R80/7 and other models,I’m not sure which ones, it was bought from motorworks and it has never been tried on the bike ,hence is for sale as “new”.
This is a fantastic way to upgrade your engine
Please see the full details:
