Are there any diagrams for the spin on oil filter modification? That looks like it would work without removing the chain, unlike the BMW element option. 3. Does anyone have a source for an owners manual?
Just use a motorcycle specific 20-50, rated for wet clutch. I have been running Amsoil full synthetic 20-50 for 4,000 miles, no clutch slippage. Owners manual can be downloaded here: http://www.tobyfolwick.com/tx750/
