looking info on 125cc looper

[53w]

I am looking for any info on a 125cc engine that was made out of an A looper by plugging one of the bores to make a 125cc. Insterested on who made it, ran it, and how many were made? Did it work? I may have the block that was used, it has the bottom bore plugged with a soild aluminum plug. Any one have any pictures of the engine?
thanks

Bruce Summers built one like that about 1972.

Right on Tim! I couldn't remember the exact year but then nothing seems too exact anymore.

My son Brian ran the M and finished 3rd or 4th behind Jane Smith.

Thanks,
Bruce

If any one is interested the 125 looper block was sold back to Bruce, it was from the engine that he built years ago.
