•Top rocker is stock, bottom is a reconditioned one.

•On the right is a rocker arm reconditioned by Guy Martin at MBP. Note the longer filled and resurfaced area.

My 1998 748 didn’t have an oil feed hole in the front (Horizontal) cylinder crankcase. I understand some models may have one.

These passages are for air cooled models that don’t have external oil lines like the SBK’s.

Here a 4mm set screw is inserted into the oil feed hole in the Vertical cylinder crankcase.

Use red loctite. This eliminates a potential oil leak at the base gasket. I filled the recessed area with 1411 Three Bond

Sealant and eliminated the green oil ring.

Nice clean piston ready for rings...

Work in a clean, organized environment

Fit each ring in bore and check the end gap
