    Limp mode

    Has any one had their Blaster go into limp mode, like the temp sensor is active, then come out of it? If so, more than once during a ride?

    Riding yesterday. Lake riding. 2-4 swells. Jumping and playing around for 30 minutes. Goes into limp mode for 20 seconds. Runs normal as I head back to the the ramp. I risk it and decide to keep playing. 15 minutes of normal operation then it does it again. Limp all the way back to the ramp. Pipe, head and cylinders feel normal. Pull plugs and they look good. New pmugs in. It starts and goes fine. Another 15 minutes and it does it again. This time it acts like it's missing more than limp mode. I stop and kill it. Starts right back up and runns fine the rest of the evening.

    Pro-Tec exhaust system, Blosion head and flame arrestor. Temp sensor disconnected.

    Mine just did the same thing. We took the skis to the ocean last week. Had not run them in a long time, probably a year or so but the blaster has been reliable as hell for 8 years with basic maintenance. I was thinking something electrical but haven't gotten into it yet.

    You may have intermittent spark on one cylinder - If you are running on one cylinder it will feel same as limp mode - I would try cutting back spark plug wires 1/8 inch or so to get fresh end if it has never been done before.

    My previous post was directed more toward original post but may apply to your situation as well - Also salt air has a way of creating ground paths more so than fresh water - Oil, grease,dirt and corrosion can create a ground path between the spark plug boot and the head - when that happens the spark can follow the path of least resistance and spark at the head rather than at the plug end in the combustion chamber - cleaning the plug boots and wires and putting a small dab of dielectric grease in each plug boot can eliminate that problem

    Dielectric grease should be a part of all ski electrical maintenance and doubly important around salt air

    Re: Limp mode

    I have been busy with work and a X2. Plus I blew up the water box. I'll try this, or get a MSD ignition for it. I also rebuilt the carb and rejetted it to Pro-Tec's specs.

    Re: Limp mode

    I have seen this problem from;

    Bad over heat sensor, bad Voltage regulator, or bad CDI. Could be any of these.

    Re: Limp mode

    Heat sensor is bypassed. I'll start checking on the others. I have a spare Blaster motor and electronics that I can swap out if needed.

    It has become a hassle so far. Two blown water boxes. I don't want to go aftermarket. I like the stock with the Watcon rear exit. Sounds good but not obnoxious. I rebuilt and rejetted the carb, and now it acts like it isn't getting fuel. It's sidelined for now. I am trying to finish my X2 and get a 750 into my other X2. Maybe the Blaster will be a winter project.

    Re: Limp mode

    If you are blowing water boxes, your timing is off.....

    Check stator. Pull flywheel and inspect. Look for stator being loose, and sheared flywheel key.

    Im betting on bad voltage regulator. They do really strange things when it goes bad. Rev limiting is one of them. A simple digital volt meter on the battery while running and trying to rev will show you volts dropping or going way too high. Of course if you arent making enough primary ac voltage at the stator, the whole system suffers. Check ac voltage output while cranking of the stator coils. Also ive seen several timing circuits crap out in cdi's. This can also be verified IF after checking stator and battery voltage they are good. Then bring front piston to TDC and mark the pto with a sharpie. Connect a timing light to a plug wire and start it up. If the mark jumps wildly around or even disappears where you cant see it then the timind circuit in the cdi has crapped.

    Re: Limp mode

    The mystery continues......

    Was headed to the lake this past Wednesday. On a whim I tried to start the WaveBlaster, sans waterbox. It cranked and tried to fire. A quick squirt of brale cleaner and it fired to life....loudly. I fixed and glassed the waterbox. I tried it intermittently and it would always fire up. Loaded and went to the lake.

    I rode it, fine tuned the high and low speed and it was good. I did long wot runs. Played, spins, cut hard corners. It was fine.

    I'll keep riding until the season is done and keep y'all posted if I can determine what it was or what caused it. Thank you all for the guidance.
