Default Re: How to eliminate gas/oil mixing

The oil injection on my Yamaha has an oil pump that's driven by a gear on the crankshaft, and drips oil directly on the crank bearing.

It would be possible to add oil injection to an HT, but in doing so, you would essentially be redesigning the crankshaft and engine case.
