So I checked for spark for the first time. Got a decent spark on the outer cylinders, but nothing on the center. Started down at the pickups, all three had similar resistance. Swapped wires around, the problem did not follow, finally found the center coil was not grounding through the new paint, now all good.

Love those easy fixes, even if it takes an hour or three to diagnose.

I know it, I was crapping myself thinking one of the CDI boxes was dead.

Got the expansion chamber header flanges done. I CNC turned and then milled them. The 1.75" tube slips inside and floats, the upper bolt will let the header float some. Seals on high temp square packing rope. My KDX200 has similar, but uses O rings, which I could also use, but the silicone is close to melting possibly.

I have had a tough time finding an H2B/C chain guard, so I made one out of a plastic shape I found. Will either get a mould off it and make a carbon one, or use as is until I find one that is affordable.
I have never liked the stock rubber intake manifold on the triples, center tube is far shorter than the outer two sides, and i'm a believer in equal length resonant intakes, so I drew one in Autocad and am printing it on the 3D printer. Plus the intake I have I think is for an H1B, not an H2, and I don't have the canister assembly either. It uses equal length silicone hose bends inserted into it. I'll post pics when its printed, 34 hour print job for half right now.
