I'm going to make an educated guess and go with kaw rider's suggestion of "a little pressure". I'm going to race this bike in Hare & Hounds and European Scrambles, so this means dead engine start. I looks like the purpose of the KIPS over rotation was to bleed off some compression. If I notice that it's harder to kick over after the KIPS bolt mod, I will have to do the compression release mod! I love this site.
When I decided to race the KX500, I never realized that I would come across modifications that seem to be good advancements without sacrificing reliability. I watched my old man desert race KX250s for years and it was amazing how competitive he was with a stock motor, and a really well prepared machine with a lot of attention to detail. He never had a DNF, wish I could say the same! Of course, being a young gearhead, he would laugh at me messing with reeds, jets, pipes, etc. to squeeze more power out of my bikes, and he used to say, "just hold it open for a few more seconds than a competitor with all of that high performance BS, and it won't matter. A stock machine in good tune is always more reliable!" Well, that's desert racing, but the gearhead in me still wants to see how much power can be made with any motor I own.
