Bike has been starting up pretty nicely. It's still a little rough beginning, but once it gets going, it's a dream. I will get a picture of the carb up soon to see if it has been drilled out or not. On a side note, the left mirror will not stay where I need it. I think the bike was dropped sometime and it got jacked up. I can't find the thread height in mm so I can replace it properly. Thanks again for all the help. | ||

10 mm, a very common size (without those silly rubber dampeners)! | ||

So.. I'm really hoping I didn't break something. I rode a decent amount today, around 100 miles. It was in the upper 80s; rather hot. Anyways, towards the end of my adventure, the bike felt sluggish, like the last quarter turn of the accelerator didn't do anything, and I was maxing out at 55. Before this happened, it would run sluggish then suddenly find new life and accelerate. No idea what this means. | ||

Gearhead, here are the photos of my carburetor. Let me know if these are not sufficient. Thanks for your time!   | ||

As best as I can tell, the aluminum plug has not been drilled out, which usually means your carb is unmolested. If this isnt done its likely that nothing else has been done and that you still have stock jetting. In the second pic, just to the left of the hose clamp screw, the small cylinder shaped piece pointing down, that has an aluminum plug in the end that must be drilled out (to adjust the idle mixture screw). | ||

Ok, are there any instructions on how one goes about doing that? I don't want to mess up my carb. Ha. Also, do you have any idea what might be the problem with my bike? I posted twice in a row. I think the primary might be too tight, but I don't understand why that would become a problem after riding for an hour and a half. Thanks! | ||
| Gearheaderiko |
Instructions are in the carb section. Primary chain gets tighter as it gets hotter. If its already too tight, then hot will make it worse, which makes it run hotter, which makes it worse, etc.,etc,. If you're not running premium, hot weather performance will suffer. Add that to the primary chain and it worsens. Okay, you're running lean. Hot weather can cause your bike to suffer more from it and if you already have hot running problems, it gets worse. Is your fuel tank vent line clogged? I cant say that these are the causes of your problem, but its the most obvious place to start. | ||

http://www.badweatherbikers.com/buell/messages/201 64/6812.html?1369876859 Also follow the BC Rider links. It is simple if you have mechanical aptitude. If you dont, then its best to get help. Carb float bowls screws strip easy, use a new or good quality screwdriver. ....and please, dont take the carb apart "to give it a good cleaning"!  | ||

FYI: Outerwears is offering free shipping this month!!! | ||
| Faseljd |
As far as the Outerwears goes, I have searched and come up with several answers, so asking the experts for the latest advise. I have purchased a project bike and it doesnt have a air filter but just an open venturi, so would like to try the outerwears. So what is the specific type, model I should order?  This is my second Blast ( wish I never sold the first) and please dont hate, I know some of you are hard on Choppas  This is a custom hand-made frame/swingarm patterned after the Redneck kit. | ||
| Ezblast |
lol - see my profile for the outerwears info, and please post some more pictures of this bike in the picture section - nice custom!!! EZ | ||
| Ezblast |
How well that carb set up work? EZ | ||
| Gearheaderiko |
 Regarding the previous carb pics: the thumbscrew is the location of the idle mixture screw. That is where the plug must be drilled out. | ||
| Gearheaderiko |
Faseljd: If you dont get the right Outerwears 'filter' your bike will run very poorly. FYI! | ||
| Freudflintstone |
Thanks for the help. I'm still trying to figure out what's going on with my Blast. I adjusted the primary chain and the clutch. Neither helped me reach a decent top speed. I replaced the spark plug and wire today and hope to check to see if the timing is off. What would happen if the fuel tank vent was clogged? I don't think it is, but I haven't pulled the tank off. | ||
| Gearheaderiko |
You don't need to pull the tank off. The vent is right on top with the fuel cap. It's that hose coming of the fuel cap assembly. A quick fix is to leave the gas cap loose and see if the problem goes away. Do not do this with a full tank! How did you adjust the chain? What's a "decent top speed"? Some people in some places will only get to about 85-90mph at best. Avoid the "replace everything" approach to repair. This very often just complicates things as everything you change that doesn't fix the problem is now suspect and could make things worse. Timing doesn't change unless you or something changes it. Given its a simple electronic ignition about the only thing that can change is loose hold down bolts or timing cup. Both are rare. Did it ever run right? | ||
| Freudflintstone |
I rode it around for a bit then tightened it until I felt/heard it rubbing and backed it off until it stopped. I still don't have a torque wrench to really do it. Regardless, the problem existed before and after I tried the adjustment. I top out in 5th gear around 55mph. Heaven forbid I go up a hill because I loose speed. When I try to throttle up in 5th gear, I get nothing from the last quarter turn of the throttle. Nothing. Not faster or slower. My RPMs do not increase either. I first noticed the problem while I was riding. It was acting sluggish, but if I gave it more gas, it would throttle up and "pull through". Very soon after, I was unable to get it to "pull" through and was stuck at 55mph. | ||
| Freudflintstone |
Oh, and it did run right while I was riding over to my brother's house. I was able to get up to 75mph on the interstate. | ||
| Ezblast |
It will go 95. EZ | ||
| Faseljd |
Have the filters ordered, should be here in week or so. The carb set-up seems ok, only driven it in the city, gotten it to 60, no hesitations. Will post up more pics and details later, thanks for the info. | ||
| Freudflintstone |
I didn't try to go faster than 75  | ||
| Ezblast |
Excellent! Have fun - that's why it's a Blast! EZ | ||

Okay, it ran fine and then wouldnt go over 55mph, what changed? Thats the question. Its very unlikely that its due to an overtight primary because they dont just tighten up on their own. Was anything done to or did anything happen between the time it ran well and now? (anything-we had a member who installed a rear tire and then his Blast wouldnt go over 60mph without surging. Turns out it was an oversized tire and at 60mph tire growth was enough that it would rub the swingarm enough to slow the bike down. Check the boot? Did you add oil? | ||
| Gearheaderiko |
There are way too many variables to guarantee every bone stock Blast will do 96mph. Rider weight, girth, height above see level and wind direction are among factors. Also, we know what to expect from a Blast, but someone who just got off his friends 600cc sportbike may not know enough to realize that 96mph wont come as instantly on a Blast. Not everyone is willing to lay on the tank either. Anyone riding through the Sierra's or the Rockies will swear there's something wrong with the Blast. Get back down to sea level and its a whole different bike. I didnt say that most Blasts wont do 96mph, but some wont for a variety of different reason. I'm just saying be realistic. 85-90mph can usually at least be expected and not everyone is willing to risk a ticket to see if it will actually do 96mph. | ||

Buell Blast spotted at McAllen convention center last weekend. Anyone here? | ||
| Freudflintstone |
I changed boot and speed sensor, but I rode on that for several days. It was after 100 miles of riding that the problem first appeared. I checked the oil but did not change it. The level looked fine. My feeling is it has something to do with the carb/throttle. I say that only because I get no throttle response for the last quarter turn. Something that is a little freaky when I have to decelerate since I unwittingly have it cranked all the way and have to unwind it about a quarter turn before I begin to slow down. | ||

Don't know how to make a new thread but had a question. I have a 2007 blast and I bought from a stealership but the bike has been laid down before. The windshield is cocked to one side and as a result touches the throttle bar and rattles. How can I push it back out is it just the three allen bolts ande adjust as needed or do I need to buy a new mount for that side? Thanks | ||
| Gearheaderiko |
Big Windshield or the small fly screen? The fly screen mounts off the headlight can be bent very easily (by hand) on the bike without any risk to the small fly screen. The same mounts are used for the big windshield, plus some additional mounts. Any bending of the big windshield mounts should be down off the bike or with the windshield off the bike. The blasts coloured bodywork is very durable and flexible. The accessory large windshield will crack easily. Most brackets can be bent back. | ||

PS Welcome! | ||

Thanks and its the big one that says buell on it I guess. So undo the three allen bolts to take it off and bend it without the windshield on and put it back andcheck for fit? I see it has the little clumsy squiggly looking metal bracket at the bottom I need to straighten as well. Does anyone have a problem with the rubber around the gas cap constantly coming up? I think the tank cover bolt is loose allowkngnit to move or rattle and it keeps coming up. Thanks |
