I don't think so, but many here say they can feel a real differance in the motors response and pull, with timing changes. If that is the case, then yes, it would be worth it. I have had the stock CDI box burn up on me while I was deep in the mountains. I could not repair it, and I was stranded. The Megajolt system, has a limp-home mode. If the electronics should fail, it reverts to the limp-home mode, with fixed timing, so the bike can still be ridden. At 84 dollars, it was less expensive than replacing the stock CDI. One of my XRL's has high compression, and is hard on the starter. With Megajolt, I can reduce the timing during starting, so the motor turns over more easily. After starting, the timing go back to normal, with no loss of performance, like you would have if you retarded the total timing. Some of the situations we are talking about here, like the electric starter on the XR600, would be a perfect application for Megajolt.
You need my 24v starting system!
