The one company that did make a kit for one of the older 1100's no longer makes them.

This^^^

Those cams in the megacycle catalog are for the single pin vtwins. I have heard that they can do cams for the dual pin motor, special order. The blanks for my cams were sourced through them. But I don't know details of that.

You want to do motor upgrades on a V-Twin I recomend you get a Harley. And save some money and time.

I have yet to find even any oversized or rebuild even pistons, much less cranks or rods. Yeah there was a big bore kit "available" for about 2 weeks in the 90's. I have yet to actually find where one was actually sold purchased or installed, so might be a myth. Even the OEM 25 and 50 over pistons are mostly discontinued. The ones I have in mine were hand poured by the motors builder, 2MM oversized and increased comp by 2 1/2 points.. The cams were bought as a Unground blanks and ground inhouse, as were the valves. Builder was part of Honda racing, so some of the stuff was factory supplied some from friend in the business. Estimated cost of my motor is $5000-10000, in the early 90's. Cost allot more these days. Lot of money for a motor that can't be fixed if it ever, has a problem.
