Yup, those old OPS 3.5 side port motors would run forever… my first mono had an OPS in it and I won a ton of trophies with it… I even ran it at the IMPBA nat’s in 1988.When I first started running in the early 70's all we had were Veco 19's. The Taipan came out but they were subject to crankshaft's breaking although a little better than the Veco. And then the front carb K&B' and right after was the OPS 3.5. The advantage with the OPS was the carb and the tuned pipe and they ran pretty good. I bought a Picco 3.5 and the piston and cylinder weren't a good match with no compression. I was told Picco had a problem with the fitment, but I pretty much stopped running so never replaced the piston and sleeve. Now I have a new Picco that needs a piston and sleeve.
