The Reedy site is not written by Mike Reedy. I actually once had a link where Sean Cochrane (now the current Reedy motor guy) said the opposite of the Reedy site. In the end, the website is wrong.
Skiddins, the Tekin Dyno may look like a load dyno, but its not designed right, so it often acts worse than a flywheel dyno. Some people have effectively tuned with them.....but its a lot of work.
Let me provide the shocker for ya.....I never take a dyno with me to the track.....its pointless. I can tell when a motor is a dog or not...
under the Big Jim forum has plenty of useful information.....try reading up on it.
Often when you need to put a lighter or firmer spring on one side, you can simply just bend the springs to the correct tension. I would suggest getting a FiddleStick to measure spring tension.....they are on our site. www.teambrood.com
