I've a Seibenrock kit 1000cc heading my way at the moment to upgrade my R80GS - just wanna get the back sliding a bit more on the windy gravel roads.
Kit has lightweight pistons, pins, new nicasil barrells, pushrods, ss tubes. Uses the R80 head.
10 hp extra is what they say - we will see.
The Au$$ie dollar is magic at the moment.
