Yeah, he's a schnauzer, best dog we have ever had. I guess if your going to
" get it hot" the more clearance the merrier. You can expect some slap when its cold, kinda like a race engine. I wonder if you'll even notice the extra noise with these engines, It should blend in with the symphony. I would be leery putting a much heavier piston in, but if its proven, and I hope it is after all these years, its probably fine. Have you seen any of these motors bottom ends out of the bike? I'm still mystified by the floating bushing. In 40 years I have never seen an engine that used it. Before I became aware of it I believe it was called a "spun bearing". Why 2 bearing surfaces on 1 pin? Even my old triumphs had conventional rod bearings. How can any of the two bearings be an effective pump itself when its vented to the other bearing?Details are sketchy, but I think Ive seen four holes in the bushing itself allowing oil to get to both sides. But this also will vent the high pressure generated on one surface to vent to the other. Hey but it works, and for many miles, so what the hell.
