One of the things I learned is that the stock gearbox on the TR5T is somewhere between wide ratio and standard. The classic/cool thing to do would be to source a close ratio gearbox. This would be the gearbox run back in the late 60s at Daytona when the Triumph 500 was a bike to beat. The problem is the difference in the races being run. The first gear on a close ratio is too high for a speedy start that is so key to getting yourself out front for a short race. A longer race, like Daytona, gave you enough miles to make up for a slow start. The low 1st gear in the bike gave me some goods starts that the bike and rider were not up to task for.
Tracks like New Jersey Motorsports Park have a lot of twists and carousels that will keep you between 2nd and 3rd more than you would expect. My experience for the Triumph was that the distance between 2nd and 3rd was too great and that it left me at a great disadvantage.
The ratio for 4th stays the same Between the different wide, standard and close ratios. It was hard to see a considerable change in 3rd from the TR5T and standard gearbox, as well. The plan is to keep all other gears, but update 2nd to standard specs.
Part of getting into the gear cluster requires tearing down of the clutch. This is where I should mention that prior to racing I never saw the bike run for more than a couple seconds. It turns out that the clutch decided not to work on race day and I had to jam another friction plate in there to get anything to happen. The truth is that I had planned on rebuilding the clutch beforehand, but the parts never arrived in time. New clutch springs and friction plates await installation.
