The book says inlet at 0.15mm and exhaust at 0.25mm, but I wondered how it would run at .15mm and .20mm ?
Run your inlet at 0.15mm and exhaust at 0.25mm as specified . The V7 700 runs tighter clearances but don't be tempted to tighten the exhaust clearance on the 750 as you'll start burning valves on long fast runs. The top end is noisy on these bikes and this is normal.
