That's a long list....All I ever took to any of the 4 races including Maine was safety wire, electrical tape, spark plugs, spare battery and jets...Actually I did think of a spare starter motor..

The Canadian vendor British Cycle Supply has a US warehouse just a few miles from Loring. They said the phones will be manned during the race days to assist any racers......

Actually, BCS is located on the base. Nice to know. Usually we are to busy to drop by and say hi.

Just to complete something I mentioned above--Here's a couple pics of the short pipes Jack Wilson told me to use about 25 years ago, one sitting still, one in motion and leaned over.

These short pipes were used by a lot of AHRMA Triumph racers back in the 90's. (Nowadays there aren't very many Triumphs out in AHRMA F750 and Sportsman 750, but folks use an array of 2 into 1's, longer single pipes, etc.) Note that the factory TT pipes are 43 inch around the outside of the bends. These are standard TT pipes cut off at the end of the bend, 29 inch head pipes,with a 14 inch megaphone on them, 43 inches total, same length as the original TT pipes. The megaphone is 13 inch to 3 1/2 dia, then a 1 inch reverse cone to 2 1/2 inches. Although the original TT pipes give a nice power band, these with the megaphones are too short, too pipey, I think, for my meager talents on a road race course--at full throttle they stumble up to 4500 or so and then begin to really pull strongly at 5000, and the engine spins up to 7500 or so very quickly, and it has above 50 ft-lbs torque from 5000-7200. In the pics above, you can see the up pipes I made to replace these identical but are a bit longer, 32 inch head pipes, and something I think really helped, a 2 1/2 inch muffler core 4 inches long, held in a 3 1/2 inch straight section with a flat end and packing--I think this eased the flow at the back and helped kill the megaphonitis at lower rpm. Now this is a sort of tractor, power starts at or just below 4000, and pulls up to 7000, with just a little trailing off as you get there. This works for road racing much better, but not so sure you guys running flat out would agree that you need such a broad spread of power. I am curious how the original 43 inch set would work for you guys, for straightaway running. Pretty easy for you to try, and switch out.

By the way, I don't remember the measurements he told me, but John Healy's bike uses much longer pipes, he told me he thinks these are too short.

I think I have two pairs, one in California with the bike, one here, set up to mount with springs over 1 3/4 spigots. Back mounts for a Champion frame but modifiable.

finally found the source for the 5/16-24 pre-drilled jam nuts for triumph conical and disc front fork caps. these are a real PITA to drill out for safety wire, and there 4 of the buggers on each leg.

sorry out of stock on the right ones at the moment, but i bought a handful here before.

lots of other interesting stuff. they even have a motorcycle/aviation oil and grease section that would be great to look through for the next motor oil debate here.

i still work 12 or 16 hours per day, so i can only hit this puppy on weekends. i need to clay the pistons and build pipes. then i'm ready to dyno it.

brand new stinking V-rated tires arrived yesterday. my H rated tires were still brand new, too, but you made them illegal with your hornet.

dont need any more parts. just more time.
