Hi peoples  On an X1 is the rev limiter different on a race ECM to the standard ECM? My bike seems to hit about 7000, maybe a bit more, before it cuts. Must admit I tend not to be looking at the tacho that closely at the time...  | ||
| Giraffeman |
I think the race one adds 500 to the 7k. And guess what I found out. My rear header had loose bolts I cant bileive I missed that. Now I have a racing kit to install but I am waiting for the new 02 sensor which I was told is better fitted with the headers off. | ||
| Rick_a |
It should be limited to 6800...mine has hit 7000 due to momentum...or something like that. | ||
| Aaron |
It's a soft limiter ... starts dropping out every other spark before it goes hard ... so if load is light enough, it may hit 7000. | ||

I nd help. Lately my Blast has been acting as if there was water in the system. It would normally start up fine, but 20-30 min or miles would act as if it was out of gas. I've removed and cleaned the tank, still same problem. I've also changed the plug, and checked the fuel tank vent, no help. Someone suggested I check the jets, so I thought this would be a gd time to change them as I have been using a V and H exhaust with stock jets. Now it seems to be worse will not even run. Is there something else I'm supposed to do when changing the jets? Any ideas on the initial problem?? Thanks. | ||

Might want to check the carburetor float level. Does it actually stall out or just lose power? | ||
| Notreallyamoron |
It would stall out. I looked at the float when I replaced the jets everything appeared to be correct. | ||
| Steve_mackay |
have you checked the throttle position sensor on the blast? | ||
| Blake |
Do the spark plugs indicate a rich or lean condition? | ||
| Notreallyamoron |
Sorry, I'm not even sure where the TPS is at. The plug I replaced looked fine, definately not too rich. | ||
| Steve_mackay |
I'm having a similar problem as you are. But mine wont do anything but idle. I think I got a bad replacement TPS from the dealer. I still haven't had time to do anything about it. But maybe you'll have better luck than I do. The Throttle position sensor is attached to the left side of the carb as you're looking into the throat of it. Just, umm, download this and read up It tells how to test, and adjust the TPS. http://tinyurl.com/4gzao | ||

Just an update. I am very very happy!!!!  I got the k&N sensor, the new exhaust and installed everyting. It works f@@king beautifully. 1 st gear, accelerate blue sky, 2nd again blue sky, 3rd a little pull and yes blue sky (well actually greyish we are in england), forth nah at 100mph I cant trust myself on public roads... So I am as happy as a snail on a fresh lettuce. So what do now a 1250 heads hmmm... better save somemoney. By the way how do you tighten the 02 sensor properly I cant get any of my tools in that position with the headers on and cant mount the header with the 02 sensor already attached??????? | ||

You need an O2 sensor tool, or a socket with a slit cut up one side to accommodate the wire. Sometimes you can get it done with a stubby wrench or a crows foot. (Message edited by hootowl on August 05, 2004) (Message edited by hootowl on August 05, 2004) | ||
| Giraffeman |
Can anyone tell me what size socket I need. I could always cut an old socke to suit? | ||
| Giraffeman |
Ah dont bother I always have the old sensor to find it out with. thanks again for all the help, i find myself checking this websit every 6 hours for updates and info boody addictive these buells!!! | ||
| Notreallyamoron |
Steve, I tried the link it didn't work, where else can I find this info? Went home today, it started up fine, everything seemed normal. Drove for about 25 miles, same problem, will just barely run, and not take any throttle without dying. Someone else suggested to check either the O2 sensor or the enrichener. Would either of these cause this?? Thanks again.. | ||

Mike You may want to go over to the thumper section and ask EZ about this. He or someone else may have the answer. Yesterday Mine started to act like it was out of fuel. Had just under 1 gal left. switched to the reserve got to a gas station and filled the tank. Still was sputtering and poping slightly at low RPM's on the primary fuel position. got home and added some carb cleaner to the fuel. Went back out and ran it hard. Seems to be running well now. As part of my routine maint, I also drained the pcv tube located just above the crank case oil drain left side swing arm. Got about two table spoons of water out of it. (Been riding in lots of moisture lately) If yo are still running the stock pcv system you may have moisture vapor being fed into the carb from that. My system has been modified and vents out thru a separate filter, but having done that it reminded me that this may (or may not) be a contributing factor. Sandy | ||

Mike, Blast's have a carb. No TPS, no O2 sensor. Sounds like you still have a carb issue. The Thumper KV section has all the info you need to get the jetting in the ball park for your setup. | ||
| Steve_mackay |
Bluzm2. Yes, Blasts have a carb. But they DO have a TPS. | ||

NEW TOPIC AND CRY FOR HELP! Please help, my 1999 X1 will not start. Yesterday she ran like a Bada@*, this morning went to warm her up before my ride to work and nothing. She turns over fires once or twice but nothing more. I have checked spark, I got a fresh tank of gas on my way home yesterday, the only thing out of the ordinary is a heavy smell of gas on starting attempts, and wet plugs. The only trouble codes that I can retrieve are for the O2 sensor, could this be the culprit even if she was asymptomatic yesterday and all of a sudden won't start. I've already tried the BAS with no luck. Any help would be appreciated. Thanks Sam | ||

Could be as simple as a low battery. My X1 just did the same thing. Just ain't spinning fast enough. SteveH | ||
| Firekiller |
The battery is brand new and still above 12 volts. Charging system was all checked out when I put the new battery in just a few months ago (actually got 5 years out of a battery), I am baffled by this. What about the fuel pump? Anybody know anything else about this mystery problem? Thanks Sam | ||
| Hootowl |
Make sure your throttle is closed all the way. They don't like to start at part throttle. If it tries to fire at idle but won't stay running, try it at WOT, but be ready to back off once it fires. Changing the plugs usually helps when this happens. I have a 99X1 and have had the same problem. | ||
| Firekiller |
The plugs are new, put them in with the 10k service. Cleaned and dried them out with some carb cleaner, checked the gap, perfect, reinstalled them with no luck. I'll try the WOT attempt and I'll let you know if it works or not. Thanks Sam | ||
| 99x1 |
"..my 1999 X1 will not start.." The ignition system has a separate ground wire at the rear of the tank (smaller of two wires terminals under bolt to frame). Do the spark plugs actually fire? (remove plug and ground while cranking). Does the fuel pressure come up? (Carefully) Press in on Schreader valve center(looks like tire valve, on left underside of gas tank) - gas should spray at 50 psi. A bad O2 sensor shouldn't cause a starting failure.. Good luck. | ||

Did you check the charge on the battery? While the battery may be new, it could have lost it's charge. The cause could be a bad voltage regulator or bad stator. | ||
| Firekiller |
The plugs have a lot of spark, I checked all the grounds (chassis, regulator, and ignition) when I started looking for possible solutions. I'll look at fuel pressure a little more closely. Should I check it when the fuel pump is firing up pressurizing the system before actually turning the bike over? The battery is brand new and still above 12 volts. Charging system was all checked out when I put the new battery in just a few months ago (actually got 5 years out of a battery). Grounds, stator output, and regulator all are withing specs. The bike never once showed any signs or symptoms of anything going wrong the day before and I was on it for a good 6 hours total riding time to include some hard runs up to the rev limiter without as much a fart or sputter. Thanks all for the input. Sam | ||

Steve, Fourty lashes with a Blast spark plug wire for me. I stand corrected! I never looked at our Blast close enough to see the TPS. After checking the service manual (briefly) I still can't figure out exactly what it does. But, it's there! Guess I better snuggle up and spend a bit more time with that manual. But,, the good news is the damn bike is stone solid reliable. I haven't had to do a darn thing to it other than a rejet. (I didn't need to remove the carb to do that, that's why I missed the TPS). | ||
| Steve_mackay |
heh, no problem Bluzm2. Just correcting you. And it's a big source of Blast problems(such as mine). I don't know WHY they have one, but they do. | ||
| 99x1 |
"..when the fuel pump is firing up pressurizing the system before actually turning the bike over? " The fuel pump should bring up pressure with just the key on. When turning the key on, you should hear the pump run briefly as it builds pressure until the regulator shuts it down. Some of the '99s had a throttle plate that would break at the shaft, you may want to look into the throttle body - you may be able to see the injector spray? (I'm guessing, I've never looked in while cranking). |
