I just bought a 2000 Buell Blast Off a friend who I harrased because it only has 3500 original miles on it... I know, a shame. Anyways I have two major problems with it so far. It has sat since 8/08 outside in sunny northeast PA. I drained the gas and put in a new batt. and new spark plug. I also thought that the two black tubes by the left foot peg that one was fuel and one was oil. Well I was wrong, one was oil and one was something very dark with some white in it, and only about a table spoon worth came out.... any ideas about that??? Also now when the key is on and I sit in the seat the electrical shuts off (EVERYTHING) when the seat is off I push around on everything and depress the suspension and it won't do it, only when the seat is on. My number 2 problem is that I can get it to start if I let it sit for a couple of minutes but soon after it starts (less than one minute) it will come off high idle and then die. I then can not get it to start unless I wait about 5 minutes. It will just turn over and over and over occasionally firing, but not more than twice. So I guess I have 2 problems and a question. I am going to pull the carb off this weekend and spray it our because it sounds like something is stuck shut. I pulled air cleaner cover off and everything is SPOTLESS. Thats all I can think of right now, let me know what you think!!!!!! THANKS! | ||

KINDA SOUNDS LIKE IG MODULE | ||
| Wacker2123 |
for what problem? And where is that located and how do i fix it? | ||
| Ezblast |
No - Das boot, and a loose ground - probably the one by the battery but check the front one also. EZ | ||
| Wacker2123 |
Das boot? | ||
| Ezblast |
Intake coupling behind the carb needs replacing - 10 dollar part. EZ | ||
| Wacker2123 |
What do you think was in the one tube that I opened???? Like I said the one was def. oil and the other one was something else, hard to tell what it was but only a little bit came out then it stopped. Tranny oil??? if it is there was none in there...? What do you think? | ||
| Crackhead |
it was oil/water puke from the pcv system. | ||
| Wacker2123 |
Nothing to be worried about? | ||
| Ezblast |
Correct! | ||
| Wacker2123 |
Ok thanks for all your help! I will be re-jetting it this weekend and check the boot tonight for wear. | ||
| Reuel |
Don't rejet until you figure out what is wrong and get it running correctly. Otherwise, you could have a problem and an unknown factor, making troubleshooting harder. The boot can be loose as well. Clean the metal where it attaches at both ends and reattach. If it has been sitting, you may have a gunked carburetor. Carb/FI cleaner can fix that. | ||
| Wacker2123 |
Ok I pulled the rings off the boot tonight and there are dry rot cracks in it so that is some of the problem, but I think that one of the jets are gunked up so I will clean that this weekend before I rejet it. Anyone know a good thread that could show me how to remove the carb from the bike...? I don't have a manual and I have never done it  | ||
| Wacker2123 |
or better do I even need to remove the carb to replace the boot and clean the carb out??? | ||
| Ezblast |
No | ||

Welcome Wacker2123! You probably have a primary carb jet plugged. So yes, clean the carb first, there are some nice pictures on this forum of the carb internals. Replace that boot anyways. You need to make sure you have the correct battery. If you got a cheap battery, one that you had to put acid in it, that is the wrong battery, you need to get either an original equipment battery or an AGM battery(Absorbed Glass Matt)which is what the original battery is. The reason for an AGM battery is they do not have liquid acid in them that can leak out when the battery is mounted in the underseat position. Next check that the battery you have in it is not too thick and sticking up too high as the seat will then press against the battery connections possibly causing them to become loose when the seat is on. Next check that all the connections at the battery and at the grounds are in good shape, tight and clean. Under the seat is the main breaker I believe is is a 30amp one that is self resetting and you can find it if you follow the small wire off the main positive cable running from the battery. The breaker will have a couple of plastic caps on the terminals to prevent shorting out, I haven't seen a Blast in over a month(I'm doing fine for those of you who want to know, as I'm still smiling) but I think the terminals on the main breaker point up towards the seat also, so they may be loose or defective also. Remember, do the easy stuff first. Good Luck! | ||

Welcome Wacker! Blast looks very clean. Your friend changed it to yellow I see! Please dont rip the carb apart. If you've never done it, there are lots of adjustments and small parts you can screw up. If anything, its just a clogged primary (aka slow) jet. Take it out and clean or replace (as Swampy said). It also does act like a bad ignition module (as twisted noted). But get that battery problem solved first. If there's a question of spark, pull the plug wire off and check to see its firing every time or check the LED light on the ignition module and see if its 'lighting up' every rotation. Both should be consistent. Again please do not take the carb off and disassemble it. The bike has only 3500 miles on it, so not much could be wrong with it. Just diagnose the problems and avoid the replace everything or teardown everything approach to repairs. All your problems are probably very simple. My 2 cents. | ||

The Battery that I put in is the original Harley Battery, and it is sealed. I will check on the breakers. The bike sounds really really good when it is in high idle (since the new plug is in) but like I said but then the rpms begin to come down slowly and it just putters out. I have a couple friends who are really really good with bikes and will jump on any chance to work on one so they are going to help me this weekend (let me watch) as they clean the carb out. update on the seat issue if you push down on the seat all the electric shuts off and won't come back on until you pull up a little on the seat. So it is something that the seat is touching. the battery is sitting well in its holder (all the way down). Even though the seat is plastic could it ground out the battery??? should i try putting rubber between the terminals and the seat? Thanks for the help so far! I love Forums!!! | ||

check the other end of the battery terminals. i am thinking that the seat is moveing the + wire and the other end is not firmly attached. When i got my blast in oct. it was a 06 with only 900mi and sat for a while. I had to keep the rpms up for the first tank bc of bad gas. I have ran 1.5 bottles of carb cleaner through it and it is slowly getting better. The auto enricher is still cutting off a little to early. another 1-2 min would be nice. the carb holds quite a bit of fuel for our tiny engine. you might still have old fuel/ varnish in the carb. | ||

Again I'll caution you: The Blast has a unique carb. Pull too much apart and you'll eliminate all the factory settings and will be worse of than before. *They are not simple to reset* FWIW: I cant remember the last time I had to pull a carb completely apart just because it got dirty sitting on a bike (or a car). They are fairly well sealed off. Gasoline will usually dissolve most crap in it and if there is a problem its usually a clogged slow (primary) jet. Trying to run the bike on old gas is a futile effort. It wont run well unless it has fresh gas. The seat can rest on the battery. While I think your missing something else, it is possible the battery is damaged and the seat is causing it to 'short out' when under weight. If its the original battery, then I suspect its bad also. "Das Boot" aka the intake boot or manifold coupler, if its bad, the bike wont run well and may cause exactly the running problem you have (as will a clogged slow jet).

OK he is in PA, trust me in the Midwest they formulate gasoline differently than they do where the weather is nice all the time. Cold weather gas is different than warm weather gas. So again you probably have a clogged primary jet, but also drain the fuel and put in some fresh premium gas. You really need to check the wire routing on your bike, but also for giggles check out the front ground strap from the frame to the "DO NOT REMOVE" bracket at the front of the engine, also check to make sure the bolts attaching the "DO NOT REMOVE" bracket are not loose, but DO NOT PUT A WRENCH TO THEM! JUST LOOK AT THEM TOUCH THEM WITH YOUR FINGERS! Those bolts are put in with Locktite and are single use only so if you move them with a wrench you need to replace them with genuine Buell Parts and use the factory recommended proceedure for replacement. The reason I just wrote all that is if the "DO NOT REMOVE" bracket bolts are loose or broken and you sit on the bike you would break continuity for the ground as the engine flexed in the frame. | ||

Take the seat off, turn on the ignition, and start pushing down on things until you get the power loss. Clean the carb by running gas treatment and some HEET through the gas. It may take a few starts to get past the fast idle... | ||

Ok when the seat is off and I push on everything it does not short out just when the seat is on. I drained all fuel and put in 2 gallons of fresh 93 octane and the problem still exists. my question of the day is how do I clean the jet and change the boot without taking the carb off? I took of the braces on the boot and there is not enough room to slide it off, and most posts are telling me not to remove the carb, so I dont want to do something I am going to regret, so I want to be sure. And for cleaning the carb I took the air filter box off and can see into the carb can I just start spraying around in there with c/c cleaner, then run it with gas treatment and HEET???? So Clogged slow jet how do I un-clog How do I get the Boot off? OH and to Gearheaderiko it is a brand new $105.99 Battery with the Harley Logo on it.... I have not checked the wiring suggestions yet.... Work in progress and it is very very cold here right now so I can only go so long till my fingers go numb.... may have to move a couch or two and bring it inside. | ||

Tighten the ground! EZ | ||

When they say 'dont take the carb off' what they really meant was you dont have to completely remove the carb off the bike. Just undo the clamps and pull the carb off, away from the boot, then pull the boot off. The carb should still be 'hanging' from the throttle cables. When the hose clamps are off, the boot can be yanked/slid off. You'll have to remove the slow jet to clean it. You'll need a small, quality screwdriver to get it out (of the recessed hole it sits in). You'll have to take the float bowl off the carb to get at it. Be careful not to tweak the float. You can unclog the jet with carb and choke cleaner. When its clean you'll be able to see through it and the little holes in the side. I usually just replace them if its a carb thats been sitting ($3-$6 each available at HD/Buell and possibly Kawasaki -allegedly a certain model uses the CV carb- or aftermarket). 42 is the stock number, but if you buy one get a #45. I'll let Reuel field the HEET question. I've never used the stuff and I'm still betting the carb is fairly clean except the possible slow jet). Glad you have a new battery. It could still be bad  , but I think when you find your unusual wiring problem it will be a simple fix. Do you have a repair manual yet? We're all just trying to help here and you've been given some great ideas (by some of the best minds on the Thumper side)! Unfortunately, we cant see the bike, so bear with us. | ||

Ok, THANKS FOR EVERYONES HELP!! We are going to tackle it tonight, V-Day With my Buell . the guy I got it from couldn't find the repair manual and I see they are 60 dollars and I can't find one to download for free online.... So I am using that money at first to get it running good. So anyways without your help I would be LOST! I will let you know how I make out ASAP!! | ||

Wish I would have known that a week ago. After reading about loose bolts on the mount I went and checked...with a wrench. It did'nt feel like the two big bolts moved so am I ok? The one smaller bolt was loose however, I tightened it and everything seemed fine. | ||
| Ezblast |
I'm thinking the ground by the battery is a tad loose - mine did that, I tightened it, end of problem. EZ | ||
| Wacker2123 |
Good news. Tightened down the positive on the battery and it was about 2 turns loose. I then checked all of the other places everyone else told me to check and they were all very tight. I put the seat back on and off a couple times and cannot get the problem to repeat itself. So I am going to assume that is fixed! I got the air box off and the boot off so I could take off the bottom of the carb. I took out the 4 screws and removed the bottom of the carb to access the jets. I took out the one that was recessed up inside (needed to find a really small flat head) I couldn't see through the jet once I got it out. I sprayed it with one shot of carb cleaner and it didn't go through. I hit it a couple more times and it started spraying through and out all of the small holes. Soooo I am going to assume that that was the cause of the stalling out. I put the carb back together but I have to wait for the new boot to come in hopefully Monday So I can test her out. Thanks for everyones help!!!!!! I will let you know how it runs early in the week.  | ||
| Wacker2123 |
What size tire can I fit on the stock rim??????? Front and rear, they are dry rotting. You guys are full of knowledge. | ||
| Ezblast |
Check our wheel and tire section EZ | ||
| Swampy |
Wacker, If that is the stock jet in your carb, you really need to get a larger one, 46 seems to be reasonable for a bike ridden in cold weather. So next time you are at either a HD dealer or an Old Skool HD shop pick one up. You Blast will love you for it and you will find that it starts easier and runs better. | ||
| Wacker2123 |
Ok Cool. Thanks! |
