The request was posted 3.5 years ago, a lot has happened since then.
I installed the Siebenrock-kit, ported the tops and installed a 296° camshaft and have used this setup for about 30kkm.
The result was stunning! Low rev torque has increased a lot and at 3500 rpm it is increased by 75% which was exactly what I was looking for.
I have not (yet) had any problems with low octane petrol but so far I have used mostly high octane.
This bike will not be equipped with double-plugging; if I get problems I will solve it in another way.
The gearing is original (for R80GS) except that the bike is fitted with an 18” wheel.

Great that you got what you were looking for -
Sorry I did not pay attention to the dates on the entries.
What did you do to the inside of the heads and top of the pistons?

Thanks for the feedback. I will maybe rethink which way i will go, although I very much doubt my next bike will be a BMW.

Membership - help keep us going!
Horizons Unlimited is not a big multi-national company, just two people who love motorcycle travel and have grown what started as a hobby in 1997 into a full time job (usually 8-10 hours per day and 7 days a week) and a labour of love. To keep it going and a roof over our heads, we run events all over the world with the help of volunteers; we sell inspirational and informative DVDs; we have a few selected advertisers; and we make a small amount from memberships.
You don't have to be a Member to come to an HU meeting, access the website, or ask questions on the HUBB. What you get for your membership contribution is our sincere gratitude, good karma and knowing that you're helping to keep the motorcycle travel dream alive. Contributing Members and Gold Members do get additional features on the HUBB. Here's a list of all the Member benefits on the HUBB.
