Got the Dyno working last week, with some new(used) acquisition hardware from Jacksoni, and some new software from Performance Trends. I haven't been able to try the race bike yet, as I've already had a noise complaint - - from my wife! So I'm working on a muffler system using a 4" x 30" x 7" truck muffler, but am waiting for some proper hose.
Here is the BSA B50SS street bike on for testing:
From the back. I had to buy a new computer, which was cheaper than getting an older model upgraded. So far, so good.
The pickup uses a magnet epoxied to the wheel.
Funny how accurate photos can be. While reviewing this pic I see that the magnet has already picked up a lot of "fuzz" which I hadn't noticed before.
And I'm working on a starter motor, as my race bikes have no starter or even a kick starter. This is the mechanism but the wheel that is mounted on the starter is only a dummy as I'm waiting for a proper polyurethane faced drive wheel.
This is the starter linkage. Hopefully, I'll get the muffler set up and the starter working next week.
The torque and horsepower numbers I get will only be relavent for making improvements because I can't determine the exact moment of inertia of the wheel. I've made an estimate and calibrated the horsepower to a stock Yamaha SR500, which was claimed to have about 32 horsepower.
I'll post more photos when I get the race bike on for tuning.
