When I got it, the oil filter was full of what looked like coffee grounds, hence the name. Only modification is that I shoved a Malossi intake (intended for a motobecane) onto the stock manifold so I could use a Dellorto 15.15 SHA rather than the leaky stock carb. Removed the oil line in order to it and I just run premix now. My plans are to get a new seat or reupholster the current one, get new handlebars and controls, and plug up the oil tank hole so I can use that part of the tank for more gas capacity. The starter lever got stuck so I now will probably have to do the kickstart conversion... Every single one of the L-case cover's screws is stripped though. Fun.
