More work today. Gussets on some of the main tubes (1/8" steel plate), and many mounts for the engines. I have thick wall tubes welded to the "horizontal" tube, and 10mm studs in the engine blocks. These allow me to "present" the engines (one at a time) into the frame, secure them with nuts, and then run in the many 6mm bolts that hold the blocks to the motor plate. Now I have to start cutting the 1/4" plate overlays, that will be the mount spacing for bearing carriers (for the cog belt drive between engines).
I also built a large mount for the left front of the forward engine (not shown), and will have another one for the left rear of the rear engine, as I get closer. I can get all 4 heads off, with the engines in the bike.....but hoping to get the engines sealed before I go to Speedweek (IF it gets done in time....not sure yet).
So far, the FZR1000 forks are handling the weight well. I have about 2-2 1/2" I can push the front end up, and (of course) the 2 1/2" tire sidewall height. I'm hoping for 4-5" of ground clearance, but may have to shim the fork springs..... anybody ever done that on these upside down forks (first set I've eve had....know NOTHING about them).
Thanks for any knowledge you could pass along.
