Post subject:  Fun riding and tuning the H1/H2

I'm calling it the H1/H2 because "H1 with an H2 motor" is a long description.

The bike has been on the road for a few years since I rebuilt it. It has a mild port job by Spec2, Higgspeed pipes, stock mikuni's with Ivan's carb kit, UFO's and intake runners.

There have been leaks around the carbs and at the oil banjo connections. Mikuni needle seats and valves with viton tips are a winner, no more fuel leaks! Mikuni 786-15005-2.5 purchased on e-bay for about $15 per carb.

Stat-o-seal washers on the banjos have stopped the leaks. I went to a local hose supply store with the appropriate bolt, they located the proper size stat-o-seals and I bought a set for 61 cents per washer.

The bike was surging a bit at 1/4 throttle. A washer under each needle raised them half a clip and cleared up the surging.

Current jetting for the H2 motor is:

112.5 mains

Needle at the center clip + washer.

17.5 pilots, air screws 1 1/4 turn out.

This is my favorite bike for riding. It has H2 power and it's easier to maneuver than an H2. The handling is a bit wobbly at speed, it might be due to the swingarm or its bushings. I'll check it out someday. The front end has tapered roller bearings. Koni shocks.

Here's a pic I took yesterday and edited with an app called "Prisma".
