Replaced the other 7 cylinder bolt threads for helicoils today (a 2nd one was coming loose on its own and got fed up with it 8-) ) So now I can start test fitting the 'new' exhaust system, but questions arose today for the valve clearance.
I have an R80G/S book which says IN 10mm and EX 15mm, and a general BMW book says IN 10mm EX 20mm (for R45/65/LS and R80 +1985), and I have this odd R65G/S so in a way for offroading you'd say a bit bigger clearance, for fiestier response smaller clearance, and higher revving engines bigger clearances. It's at 15/20mm now
So what do you use (with which engine) and what would you recommend, onroad inner-city and B-roads.
