Hi everybody,
jdincau: using copper for the plug spacers
Did not want something that will compress too much and stick to a bad or dead sparkplug, we'll see when it actually runs...
Vinsky: modified kit which is made for high compression or blown motors
Must be a single fire kit based on the last XRs Fairbanks Morse, around 1980. Used to have bits for that conversion. Not so sure it's that good since a well proven old timer trick to revive a dying magneto is to cut the plug wire in the middle, strip a bit on each side and insert a bakelite button in the circuit to force the spark to jump across it, this produces a better spark. So me think 2 spark plugs on one coil isn't that bad???
Twin magnetos will also allow me a degree of change between front and back if needed.
OZ: let me know how the documentation side of things goes
The EPA man is a bit concerned, told me me bike don't look like a salt flat racer, wanted to know all the built details blablabla... Haven't received the race exemption yet!!! I'll give him another week before going back to him...
Did you use a custom broker to clear the USA customs? The DOT man pointed to me to one in San Francisco that seems OK and knows the procedures... but with a fee!!!
Did the bottom end this week end, took my time to make sure it's all decent...
Started by making a small alloy ring to reinforce one of the Torrington needle bearings, a known weak point in these trannies where the speedo drive normally sits, hence not very thick and hanging over somewhat. These cases, 55 years old, don't even have a crack there,(
There are others elsewhere as you can see
) but prevention is better than disaster...
Gear box shafts end play... Countershaft is hard to get to, fitted the cases without the main shaft, fit washers until it's just tight by checking/poking through the mainshaft hole, then delete a 6 thou thick one for about 6 thou end play...
Mainshaft is easy, you can use a dial... 6 thou as well:
Split the crank on a piece of hard wood to check rollers and pins, it'll do nicely, reassemble and trued, 2 thou on the wheels periphery:
Cleaned all the bolts, ready to close the cases!!!
Little bit of showing off, safety wire on the drain plugs!!!
So long, Patrick
