I have a 85 ATC70, previous owner scwered up the head, so I'm looking for a cheap replacement. A guy may be willing to sell one off his 87 trx70 for cheap, do they interchange?

Yes, they will intechange. Also if you can find a deal on a trx90 engine, it will bolt in to the stock location.

I have two differant motors here.
One head is marked: HM-F2 the other is HM-F5
One cylinder is marked SY-A3 the other SY-B2
Any ideas what the numbers refer to, or better yet, can you decipher this?
thanks again...

Probably just some kind of manufacturing number or dating system. They should still be pretty much the same engine, no big deal either way.
