N/C 250 Mk3 Motor - What frame?

[gregwils]

I purchased a basketcase 250 motor a few weeks ago. I didn't care about the VIN at the time since I was buying it as an extra motor. I realized it was a M3 motor once I got home. I now feel like I might want to do something fun with it and build my own. I am not sure what options might be available to me.

I don't intend to recreate an M3 and tell people it's an authentic M3, but have no issue building and calling it an M3 replica with a real M3 motor. I also have no issue with creating a bitsa with a different frame, tank, fenders, etc. My only concern with a bitsa is that it would be my first one and I don't want to spend $5k or more then be disappointed.

The easier path wuld be a standard 250 monza frame and add the needed M3 tabs then find a Diana tank and fenders. I am not sure if I want clip-ons and rear sets or not.

I am open to any suggestions on frames, etc or let me know if anyone has the majority of a Diana/Monza that is motor-less in the US that they don't want or need. Thanks for your thoughts.

Any narrowcase frame will be suitable for your purpose. The basic structure of all the various models is the same. More important is that you start with a frame that is in good condition. Finding a decent Mk3 frame or chassis will be challenging. Scramblers often had a hard life. Your best prospect would be a Monza/Sebring. Recreating a Mk3, even if you choose to do without original type rearsets and clipons, is an expensive proposition. Before you start accumulating chassis parts, you might want to assess what that engine needs. That alone could command a good portion of your budget.

Okay, I didn't realize that I could pump $5k into the motor. My budget is pretty fluid, but I will focus on the motor first. Thanks for the suggestion.
