Heya all, I was hoping you could give me some help with this problem I'm having. My speedometer stopped working. I drove to a parking lot, it worked fine, then on the way home, I noticed that it no longer worked.. I'm guessing that a wire somewhere came loose, but I'm not sure where... any help is much appreciated. | ||

Your speedo sensor has probably died, a problem with the old sensors. The part has been revised, and after you replace it, you wont have a problem. | ||

Thanks for the help.  I found the other post about someone with a similar problem and that had some good info on it. Is there any way to fix the part without replacing it? The other thread mentioned cleaning it... how does one do that? Just wipe it down with a rag and some water? | ||
| Mutt2jeff |
You might find some metal shavings stuck to it, it is basicly just a magnet. Wipe the shavings off and give it a try, but i doubt it will work. | ||

Well, I'll give it a shot... One more question: I'm having a hell of a time finding an allen key that will fit the bolt holding the speed sensor in place. Anyone know what size key it takes? | ||

I've been reading up on all the speedo problems as mine just went out. Still am getting power to it so I'm assuming its a dirty/ bad sensor. Only I can't find the sensor! Need help locating it or what it looks like. | ||

On case behind front pully. EZ | ||
| Shad |
is it visible without taking anything off? | ||
| Ezblast |
Yes - you'll see wires coming from it. EZ | ||

So, I hit a bump about the size of a snapper(Turtle)... And my Speedo instantly died. All lights work on unit but no speedo. Gauge flickers like normal when first keyed, and diagnostic codes show all clear. Pulled out sensor and cleaned to no luck. Is it time to call Chicago HD? Only $47!!! My local stealership wants $80... | ||

Check that the plug into the tach is tight as well. EZ | ||

should there be wires going in between the front pully and the frame? my speedo is out, has power and there are some wires that are going in between the front pully and the frame (they appear to be frayed, which could be my problem, but are stuck in behind the pully fairly well. should I pull them out?) just to the around the corner from the front pully are 2 wires leading to nothing...they appear to have been chewed off. Are these 2 wires supposed to be connected to the 2 wires that are stuck in my front pully? thanks. | ||

Picture? The speedo sensor - picture in manual - is on top of the engine case behind the front pully. The sensor behind the pully is the neutral light sensor - with two wires going to it. EZ | ||

Pictures as requested. - 1st view is from under the seat where you'll see a wire #1 outlined disconnected in red and in the far back, wire #2 outlined in green hanging down in between the front pulley.  - 2nd view is from the top of the belt guard looking down into the front pulley (you can see the wire going straight into it)  | ||
| Ezblast |
The busted wire in red leads to your speedo sensor, the wires behind the pulley go to the neutral sensor. EZ | ||

awesome EZ - thanks! Now to figure out what to solder that back to... also - got the manual from the yahoo group. HUGE!!! | ||

My newly acquired 03 Blast speedometer stopped working. Lights do not light up whatsoever, ONLY the odometer (mileage indicator) is lit up nice n bright. My needle just stays at 0mph while riding. No lights turn on, on the speedo when signaling or while in neutral. What could the problem be? | ||

Ooh....Corpus Christi, damn lucky you are! Welcome to the Thumper Forum 2rill! Does your speedo jump when you turn the ignition on or off? Have you checked your wiring? The usual problem with the Blast is the speedo sensor goes bad, that is the sensor at the top of the transmission output shaft...see the picture above. You can try removing it and cleaning any debris off the end of the sensor first but usually it just goes bad. You could try checking the sensor with a VOM set to a low AC voltage and turn the rear wheel by hand. Good luck, let us know when you find the problem. | ||

thanks Swampy... ill try that today after work... yeah Corpus is OK... but not so much if you're a biker. LOTS of non-driving people around here. One of my friends got in a huge crash 2 months ago and it almost cost him his life. One of his friends lost his life while riding as well a few years back. Always people on cell phones while driving and im beginning to think signal lights do not exist around here anymore. haha | ||
| Swampy |
Yeah, tell me... I was sitting at the light by the Grand River, the roads were the slightest bit frosty last Saturday, some clown boy in a Toyota 4Runner that was all jacked up and coming the other direction decided he needed to turn all of a sudden. All I heard was squeeling tires and I looked up to see this giant 4wheeler sliding sidways towards me, luckily the guy ended up in the lane next to me pointing the same direction as me and when the light turned red we all took off together like nothing happened... | ||

Hey all! Great information, now I know where it is, and how to get to it... but now I need to know how hard it is to fix it lol. Can a somewhat inexperianced Blast owner fix this without making it into a week long project? | ||

Been having problems with my speedo and odometer. They work when bike starts then crap out after a short distance. Also replaced my battery only to have it fry after a long run of and hour. Started hearing a whistling sound which turned out to be the battery. It was so hot it popped one of the Sealed ends in of the cap causing the whistle. After checking it at my mechanics we tested the voltage regulator only to discover it charging at 20amps. (••••••) so we unplugged the stator from the regulator and I drove it home cuz I needed to order a new one. Low and behold, the speedometer/odometer both worked like new!! So if u r having a problem with your speedo/ odometer, unhook your stator and try it without and I bet u have the same result. | ||

It is the voltage regulator that is the problem | ||

Ok, here is an interesting one. My speedometer was going all the way around! Then I would be doing about 70mph or so and it would suddenly drop to 0 then back up or just spinning 360 until it was on 0. It would do this very quickly on and off. It appeared to be shutting off and turning on so I checked the battery + terminal was loose... put in a new thumb bolt and now it does not drop to 0 but last night I was going about 45mph or so and then it rapidly began to climb until it maxed out! Every time I stopped it would drop to 0 but then about 45 or so would just climb to max no matter what I did until I slowed down to 30mph where it would again function close to normal. In the morning I was leaving work and bike started but then died. After several attempts to start it I had to jump the thing. The + terminal was pretty warm and it took quite a few minutes to turn over to get it to start. When it did there were some coughs and occasional backfires. I know some would say this is caused by a loose boot etc but the front isolator was just replaced this month along with a new boot which is still tight (Yes I checked it). Once home I put it on a battery tender all day and tonight no problems. I have a difficult time thinking these are separate issues, there has to be a root problem other than changing bikes or perhaps the rider. lol | ||

After all the problems I have had I am tempted to tear the WHOLE bike apart frame and all into a bunch of boxes then clean, spec all parts and re-assemble it. In fact this late fall I may do just that. If I do though I am sending the case in to get the biggest bore kit I can possibly fit on it. Any suggestions from those who have the big bore kits out there? Which is better or is it even worth the effort? My bike maxes at about 95mph with the wind. What can I expect a kit to do other than get there quicker. I do not know if a guy can change gears on this thing to max out faster or not. Any thoughts? |
