Congratulations! Don't ever let go of that bike!
I had 2 LM's that came through Raceco 333 Kent Ave, Brooklyn, NY. A '77 and an '87. I still mourn the 77. It's in good hands.
Do not confuse long time - several years gone, "Moto International"/ They were in Seattle, WA. A wonderful MG dealer and the owner was/ is the author of Guzziology.
IIRC: Raceco went back to UK in the early 90's. Their trans. and final drive tooling went to Charley Cole, Wickatuck Dr. Sag Harbor, Long Is., NY. I believe he has retired. Former serious, competent - man of steel type - road racer.
Raceco, UK continued to manufacture sleeves, barrels, pistons, cams, head work, etc., but focussed more and more on Formula Ford race engine development. I believe that company is now defunct. They campaigned a Guzzi Daytona for many years. IIRC: It was @ 14 or 1500cc when they sold it to an independent grp.
Good fortune, R3~
