I use nothing to support my carb, and it ha worke for me. I've had to replace one carb boot in 10,000 miles Of course, when I ride, my knee is in front of the air cleaner, so I am not putting any weight on the intake, or squeezing it. A few others have had luck with no bracket also, but YMMV. I will often go on a 200+ mile day ride woth no spare parts or tools either. I gues I'm just a risk taker  James | ||

Jprovo, That's what I'm gonna do for now and see what happens.about all I take on ride is screwdriver,adjustable wrench,pliers,tire plug kit(serious emergencies only), and a small air compressor. Got my pro series intake on today, re-jetted carb per instructions in the dynojet kit and man what a difference.I cannot wait to get pro-series exhaust. | ||

I have a carb question: How badly should the airbox vibrate? It seems twice as bad as anything else on the bike. | ||
| Gearheaderiko |
The airbox should vibrate with the engine since it is rigid mounted with it. If it moves more than the engine does, somethings loose. | ||

Jugallo94 Can you take another picture of that carb brace, I can't tell where it is attatched. Thanks | ||

Guys, on the dynojet kit they said that the blast needed to be leaned out.they call for a 155 jet with both aftermarket intake and exhaust. does this sound right?I know Gearhead said they use a sdifferent number system but am still concerned. I do however have an H-D dealer that is an hour and a half that does the free dyno run and I will do that. But again am just worried about the jet numbers. | ||
| Jprovo |
Different emulsion tube, needle and jets, you should be fine. I know that others have run the dynojet jet kit with good results. James | ||

I will take a better pic today. Make sure you locktite the bolt. Mine vibrated out on the way to wisconsin friday. Knew I forgot to do something. On the way home of Spidey and my 550 mile trip sunday My boot tore due to no support about 100 miles from home. Duct tape works excellent for sealing a torn boot we found. We noticed about half way into the trip out there that there was no bolt supporting the carb to the bracket, I dont know how long it had been missing, but it held the rest of the way out. Didnt think to put one in while at appleton, and rode almost all the way home sunday without the bolt. Great ride, But damn am I sore. | ||

Swampy if this is still not light enough for you to see let me know and I will email you the pic.  | ||

Jugallo, Is the bolt holding brace to bottom of carb just drilled and tapped? | ||
| Tnthumper |
I don't know if it will be as good as the one Jugallo has but I used some angle aluminum that I had left over from mounting driving lights to brace under carb. It is not bolted to carb but is supporting weight. I have used some silicone tape to keep from having metal to metal contact and am using spring to make double sure brace stays under carb. Don't really need it as angle is stiff enuf but a little insurance never hurts. | ||
| Jugallo94 |
Yes. it is just tapped and drilled. It was where the carb drain would have been if there was one. Drilled and tapped to 1/4-20. | ||
| Swampy |
Looks great, I can see it just fine! Thanks BTW, You rode to Wisconsin with Spiderman? What was out there? | ||
| Jugallo94 |
FBRAT kicked off from appleton on sunday. It was a great weekend. rode 464 miles out there on friday. On the way back with few different routes we put 550 miles on sunday. | ||

Does anyone know the stock rear wheel torque/horsepower figures? I used the dynojet re-jett kit when I installed pro-series intake/exhaust and have a free dyno run coming to me and want to compare. Any suggestions on what to ask for in way of printouts or other info would be appreciated since this will be the first time I've ever had a dyno run on anything. Thanks in advance. | ||

I just added some helpfull links to the top of the carb section page - so go to your local dealer buy a 45 primary and 175 main and rejet that puppy, then drill out the air screw plug and turn it between 2 1/2 to 2 3/4 out from light bottom - enjoy! GT - JBOTDS! EZ  | ||

Ed..., The links to the Re-jetting instructions are great..! Now I know what is going on. With our BadWeb Brothers..I may never have to see the Dealers ever again...!!    | ||

OK everyone here goes. After installing pro-series intake and exhaust and using dynojet's re-jet kit my Blast is now showing 24.87 hp and 50.40 ft-lbs of torque at the rear wheel. Air/fuel is running 14-14.25 across entire rpm range. This was done at 93 deg and 23% humidity. Looks like hp hits peak and stays at around 2700 rpm and torque hits peak at around 1800 and does'nt fall below 40 ft-lbs til around 3200 rpm. Shop said air/fuel looked good and I'm real happy with torque increase. THANKS AGAIN FOR ALL THE HELP!!!  John | ||

should be 28/28 - I'm glad your AF is cool though - thats most important! GT - KBOTDS! EZ | ||

50.40 ft lbs of torque? I seriously doubt the torque is at 40 ft lbs. Please post the dyno sheet, something is amiss! | ||

Tnt, Glad you're bike is running good again. I hope all stays well. The bad gas thing blows me away. I honestly have to say that I've never had a bad batch of gasoline. Maybe here in California, there's too high of a turn over rate at the pump to allow the gas to go bad. I hope you never get another bad batch again! I wonder if the dyno operator rev'd the bike all the way to rev limit, or if he stopped at 5000 RPM. 40 ft-lbs is ungodly in a stock blast, and 50 Is darn near unbelievable. I hope that the dealership just pulled up the wrong numbers to tell you, and aren't outright lying. I expected to see someting in the 27 Hp - 27 Ft-lb range. 50 Ft-lbs is a definite shocker. Here's a good dyno chart showing some stock engined blasts with exhaust pipe mods. http://www.badweatherbikers.com/buell/messages/20164/10331.html#POST53748 | ||

James, On the gas it has not been that long since Katrina went thru gulf and that is where we get most of our gas.Since this is first time I've ever gotten bad gas from that station I'm willing to call it a fluke. As for the dyno graph I don't have a scanner and rpm range only goes to 3500 on my graph. What I was planning to do was get it run at a dynojet dealer by work and use my free dyno run certificate to cross check results. Could I get a little more HP by richening carb with next bigger jet? Could some of the differences be due to the Dynojet kit using a different needle,diffuser and enlarging hole in slider? And it does seem to be ALOT stronger in low and midrange. John | ||
| Jprovo |
I dunno about getting more power with a bigger jet. If they are not measuring horsepower above 3500 RPM, you are not going to get an accurate reading. On a stock bike, peak horsepower is around 6000 RPM. It soinds like the pipe and rejet did it's job. I'd definietely get it re-checked though. James | ||

Has anyone enlarged the vacuum port on their carb? I see that another website is saying it should be opened to 1/8 inch. ?? | ||
| Gearheaderiko |
If the vacuum port is plugged (as it is on the Blast), I dont see how drilling it will affect anything. | ||

BAD GAS...in Hawaii the Navy base main gas station had tanks that had water leaks...twice 6 months apart I bought a tank and had to drain it and clean the carb...it was very very annoying...asking others about it it seems that any small engine (lawn mowers included) have problems with that station's gas...I used the ATM gas station (no attendant) after that (it's 50yards from Pearl Harbor so the tanks have to be good)...water in a small motor can really mess things up} | ||

Thats not cool... I'd throw one of these in my saddlebags: http://www.mrfunnel.com/ James |
