Read and read again. If you want adjustable rev limiter, it needs to be done one way. If you just want to get rid of the rev limiter, it can be done another way. So it depends on what you wanna do.

I just order some resistors and pots, I have no idea if I got the right stuff, we will see what happens when it gets here and I start soldering things together. fingers crossed

I'm curious about whether anyone has removed the potting on a dead enhancer to see what the design looks like and what the similarities/differences are between them and the stock cdi. I wonder if they use a modified version of the stock design or if they went with a completely new design. If they used a modified stock design, maybe the differences could be compared to determine where things could be changed on a stock cdi. After all, I have always heard that the msd has more advanced ignition timing. We could also find out about the "hotter spark" they mention in the product info.

Id like to know if there was any success with using the gallon cans of carb dip for depotting the board as well. I have a supplier for actual depotting solvents but the carb cleaner would be cheaper and easier to source. Even though #zero said his dip session took two weeks. He never mentioned whether the carb dip used was a consumer grade dip or commercial/industrial grade solvent. The guy who mentioned giving a go with the consumer grade gallon size dip never updated on whether this worked. I know the dip available in recent years is not as potent as the old gallon carb dips. An overnight dip with the new stuff doesn't even remove the paint like the stuff I used to get.

There were two people who mentioned having modded cdis where the stop function no longer worked. There were no comments on this and also no mention of which mod these people had. Whether it was removal of limiter or adjustable limiter. Is the issue with the stop button common? A known issue? A side effect of one or both of the mods?

Are people having long-term success with potting the modded section of the casing with silicone? Most things I've seen sealed with silicone seem to eventually start leaking as the silicone ages, peels, etc.

I've deleted the rev limit on a few, lasts forever. Stop function has nothing to do with it, any issue with that is likely caused by circuit failure else wheres on the board , the h/b switch or the plug near the elec box. By the way I just use the jumper mod - no rev limiter at all - The adjustable type is to much work for me.

I have dissolved a dead enhancer in methylene chloride. It has two boards with everything spread out. Good luck removing the urethane encasement without ruining many of the electrical components. A modified stock box is fine, no need to make it adjustable. Just replace the 91 or 100 ohm resistor with a 75 and seal it up with urethane adhesive. This will get the limit near 7500.

i do not see pictures that show the soldering points for the "remove rev limiter mod" i see them for the adjustable mod. i think the soldering points are different?
i did this mod to my fx1 a while back. it worked great but i lost my notes and it seems the info is not in here. if you have the info please post it.

Thats because the "no limit" mod is such a bad idea.

I'm lost. I soldered the 2 points together about 4 years ago and still running strong. What do you mean, take advantage of extra rpm's? Put on a B-pipe. Thats extra rpm's.

Its more fun to ride then to spend 100 hours tinkering/modifying/fixing/spending money on a modification that won't gain much any noticeable difference.
