Just picked up this '75 550. It has a '71 500 motor in it, which is supposedly bored out to around 626, however I imagine that it is closer to 600. It is quite apparent that someone has done some work on the engine, as all of the philips bolts were replaced with allen bolts (thank goodness!)
It has a set of kerker 4-1's on it as well, which I'm stoked about. They have a few rust-through's on the tail end, but I will be going through and patching holes and re-packing before I spray and/or wrap them.
The chopper package is soon to be coming off as well. Just got the forks off, and am putting the stock forks back on, which are in very good condition surprisingly.
It may be a sacrelige, but I am considering repainting the tank and sidecover black.
It also needs new rubber. The rear rim is a 16, so I am thinking I might try to put a 130/90 H16 Spitfire on there, with a 100/90 on front. I'd like to go skinnier on the rear, but am not having any luck finding something of lesser width (and lesser cash) for the small 16 rim.
Well, just wanted to share with everyone. Nice to have a project to get me through the rest of the Minnesota winter!
Cheers!
