BMW Isetta Engine Rebuild

I am new to the forum but thought it would be a good thing to join as long as there are enough Clissics or even Motorcycle owners out there.

I have a 1960 BMW Isetta that I need the engine rebuilt on. Wondering if anyone out there knows of someone that could rebuild this engine. It is essentially a motorcycle engine in the car so maybe someone with a motorcycle may know. I live in Ontario, Canada so anyone in Ontario or around the northeast US states would be ideal.

If you can help me out, please let me know.....this is something I dont want to try on my own in fear I might do more dmamge than good!!
