I tried to Email a long while back when I bought a real nice classic Hotrod "BU" motor. Its internals was redone by Cooper Jess. I never heard nothing back about replacement or upgrade stuff though from sidewinder. I think I tried to contact them twice as I remember.
Anyway, I imagine Ron Selewach gets more Emails than most would want to deal with. I don't want to bother unless Im buying and that's not possible for me right now. Luckily, I found a Y-80 that I got for 300.00 and I went through it. I decided that that would be a better engine for B-Mod someday. It would still be nice to set up my Hotrod though If I knew I could replace parts on it more readily. The 20 HR motors are so dam rare its ridiculous. One could hardly get parts for them. And no fellas...........I aint selling it!!! Always wanted one, now Im happily stuck with it!!
By the way......I made a piston stop for my Yamato to time it with in the future. I took a 18mm spark plug extendor and drilled and tapped for a threaded bolt through it. The way it works is by using it to find a center point on the wheel. Take out the stop and put the wheel to to TDC. Then put the stop back in and run the bolt in gently until it contacts the piston. Then take the stop out and measure it. Add (.200) to it and put a lock nut on it to keep it as such. Set both points at (.016) exactly to ensure 180 degree firing as close as possible, and timing will be easy and quick with the new piston stop. These aluminum plug extendors are available at Pep-Boys auto parts stores and others and are easy to make a piston stop with.
