blaster rev limiter problem?

[jkirkland]

I have a 95 blaster with a 61x, dual 38carbs, riva red pipe, ported cylinders and a lightweight riva aluminum flywheel. My problem is the ski has what seems to be a rev limiter at around 3000 in the water or on the trailer. When it is in the water you can hop the ski out of the water and it will fly until you let off the throttle then it goes back to hitting the rev limiter. I dried the pipe out by crimping off the hose to the stinger but it still does the same with the pipe dried out. I also have the overheat sensor out of the head and since it was still being limited I snipped the wires and have kept them from making connection. Has anyone else ever run into this before? Thanks --Jason--

you check the plug wires for burn back?

Are you talking about cutting off the last 1/4 inch or so incase the wire has gone bad? I havent checked that yet but I will. This happens all the time on the kawis I have. The problem has gotten progressively worse on the blaster. It used to only do it when you did some circles or played around for awhile. You would have to hop it and run in a straight line for a little while. I thought it was getting water built up in the pipe and was needing to be cleared out. Now I dont think that is the problem. Thanks for the help and I will check the wires in the morning. --Jason--

i bet thats whats wrong. you running the the stock cdi? i have also seen AM flywheels not trigger the cdi. an msd will fix that.

if the over heat wire (pink) is grounding it will make the rev limit 3k rpm. Open up the electrical box and unplug it. maybe even put a little electrical tape around it.

Thanks for the help. I cut the wires back, great suggestion. It didnt fix it but it sure seems to be a problem that occurs alot and I didnt even think of it. The low speed jets were closed to much. I turned the jets out and the motor came back to life at an idle. I just replaced a head gasket and put in the lightweight flywheel. Between these two it must have needed more fuel down low. I messed around with the high speed jets at the lake but I never thought the low speed could keep it from taking off. Ithought once you had the throttle pinned the high speed jets were in control but I guess that is why everyone tells you to set the low speeds before tuning the high speeds. Thanks again--Jason--
