Hmm...I think I might be able to do it with a couple of 90 degree pvc joints to create a skewed U shape. Maybe even put in a straight piece at the "bottom" of the U (stretch it sideways) to move it lower on the bike. I think I just found my project for this weekend.  -- dan | ||

Dan, I think you a making this more complicated than required. Several things need to be considered the most important of which is total intake length. Which calculated for the Blast is somewhere around 12-13" (this is from the intake valve to the intake inlet where you attach the air filter). The intake that I made up is just on the outside of this and will probably be shortened some when I go to Aaron's for dyno work. The one that you are describing would be muchlonger than effective. Care also needs to be made so that temperature of incoming air is controlled, so if the aircleaner(s) are to the rear of the cylinder then you will be drawing hotter than desired air. Within reason the cooler the air the better. This is just my opinion  but keep thinking there is always room for new ideas even if we critique them. (Not all of mine have been barnburners trust me) Ray | ||

Ray, Have you got a length from the valve to the front of the Carb? I had forgotten about the effective length when I built mine but I'm fairly sure that it is shorter than yours | ||

re: selling my blast 7/3/02 I can't sell it! I imagine if I were a heroin addict that quitting that would be easier than selling my blast! Anyway, bought a Bub's... I like loud and tuned for the low-end is good up here around town. It comes with "hassle-free" installation guide and mounting. just wondering if anyone has installed one and if any special equipment is neccesary... I don't have a complete garage but I believe I have adequate tools? | ||

Kyuss use of a torque wrench is a nice thing and make sure you get a new exhaust gasket | ||

Promised photos of my intake...this bike is truely approaching a ratbike      | ||

Kyuss- I HAD a Bub's on my Blast. I did NOT like the pipe overall. Perceived characteristics: Light, simple, loud, grunty, good welds on inadequate material (ask me how I know) Install was a total no brainer. I got mine used so I had no hardware or instructions and had to improvise on the rear mount. Used the stock spacers and things lined right up - if I remember correctly. With my 200lb lard ass on it, I managed to put a 45-ish degree flat spot on the left of the muffler on some uphill of camber turns going up Topanga Canyon here in SoCal. You seem like you wouldn't have that problem if I remember your profile's pic correctly. When mine broke, it broke AROUND the weld... The base metal for the can was too thin, though the weld was obviously up to the task. The V&H seems like a more robust piece of equipment. Bottom line: If you like GRUNT and NOISE, the Bub's is a good pipe. However, you're more likely to see the rev limiter with the stock pipe. -Saro | ||

Xgecko, How do you like the White Brothers pipe on your Blast? I am thinking I want either a WB or a Kerker. | ||
| Xgecko |
I like the WB. It's a bunch quieter than my K&N was. Which is good for my neighbors I haven't had it on a Dyno yet but my hope is to do that in the near future. | ||

Well, I finally had to do the walk of shame last night. My 2001 Blast decided to die on me. I'm just grateful it happened 1/2 mile from home rather than 1/2 a thousand miles from home. Pushing a ~385 pound motorcycle for a half mile is not easy. Or maybe I'm just a huge fatass. It was at the end of the workday though so I was drained enough as it was. The only thing I could think of was "I shoulda bought a Ninja 250". But I'm over that now. I think.  I was riding home, when it just started spitting and popping like a mofo. I was slowing down for a stop sign when the engine just slowly died. It started back up again after a few pushes on the starter and twists of the throttle but it died again about a block from there. In my frustration, I think I probably drained the battery trying to start it. The starter still cranks but the engine doesn't want to turn over. Anyway, I went to the dealer today to get some new plugs since I was told they might be fouled. Sure enough, when I pulled it, it was black as night. So, I put the new one in and tried jump starting it using the car... no dice. I tried to push start and that didn't work either. I'm gonna put the battery on a charger tomorrow and try from there. Yes, there is plenty of fuel in the tank and the fuel valve is on. Clutch is pulled in, engine switch in the run position, ignition is on, bike is in neutral, blah blah blah. Anyone have any idea why my Blast is dead? Thanks in advance! I'll let ya'll know how it turns out either way. | ||
| Buelliedan |
By any chance could a wire to your coil have been disconnected? Sounds to me like you have no spark. Do you have one of those spark checker tools? That would be where I would start. | ||
| Xgecko |
does it turn over? It could be the dreaded kickstand switch. baring that a dead battery shouldn't stop it from push starting. I know because I have tried to kill my battery before and it still push started | ||
| Strat81 |
I don't have a spark checker tool. When I was putting the new plug i made sure both ends of the plug wire were firmly attached at both ends. So maybe the whole coil is shot. It doesn't sound like it's turning over. Sh*tty part is that I work for a HD/Buell dealer but to have them pick up the bike I have to go through the "regular" channels and pay full price because of insurance and what not. Techs can't really help me since all of they're tools are at the dealership, not in my garage. I have to find someone with a pickup truck and go that route, maybe. I looked through the shop manual and it lists the stuff the mechanics said. A lot if "it could be this" or "maybe it's that" and "don't forget that". | ||
| Xgecko |
Turn out the lights and hold the plug against the engine...push the starter button if you don't see a spark then it's probably the switch...or you plug wire or the coil | ||

Because some people who will remain nameless wanted to see my little ratbike with a more entertaining backgrond since I'm in Hawaii I have changed my Profile photo to show a bit of the view from Diamondhead near my house. Is that better Blake????  | ||

Ok, you guys will have to bear with me here. It's been a long day at work and I'm a little bleary eyed. Ray - That 12-13". Is that from the carb to the end of the filter? Or from manifold? What I want to do, and maybe it would be completely unnessecary, is point the intake forward. I understand what your saying about the cold versus hot air, I hadn't thought of that before. If I can get the intake opening up to be parallel with the cylinder incoming air should considerable cooler. I mean, the airbox opening is tucked in behind the cylinder... Also, would the intake diameter affect the 12-13" length? i.e. A skinner but longer pipe? I really need to go to the library or something for a couple hours and get some of these things figured out. You guys are doin a great job supplying me with info! (ray) Tony - That looks great! If I don't get something else figured out I'm going to have to make a copy. What size Kurykan spacer did you use? (Part #?) I think I had a few more things to say, but can't remember anymore. Need sleep. I'm sure I'll have something to post in the morning. -- dan | ||
| Dansherman |
One more thing... Tony - If I had seen that picture in your profile while there was snow on the ground here, I'd probably cry. -- dan | ||
| Ezblast |
Bub exhaust - 5hp max but torque is another matter, Direct hits ign. coil system, gutted air box, 45/175 jets,a few twitches here and there - will get to dyno probably in 3 wks - have found one in area that is reasonable - perhaps cam change next - any sugestions - emphasizing torque - please  Blasting on the darkside!

Tony, Should have my head back this coming Monday from Axtell. I will measure the length from the intake valve to the inlet of the intake port. Otherwise the total length of my present intake from inlet of my intake through the carb to the inlet of the intake port on the head is 9.815". BTW, sorry about the carb whoas you are having wishI had some good answers. Dan, The length should be from intake seat to intake inlet by my understanding. This length is very independant on RPM and flow carecteristics of the head. I plan with the mods that I have been making to turn 8,000 redline and have had my head modified with porting and larger valves. With stock set up the lengths look to be between 13-15" but this still doesn't allow you to get the filter far enough forward IMHO. These calculations come from Denish. The answer to peak purformance still requires a dyno as the calculations only provide an educated guess. Ray | ||

Yes well my woes were self induced  and with luck I can fix them until then I'm still on two wheels...just powered by me not Buell | ||
| Strat81 |
OK, update: The bike is getting spark but the motor still won't turn over. The fuel valve is ON and there is plenty of fuel in the tank. So, this leads me to believe there is no fuel getting to the carb. What should I be looking for? Thanks again!! | ||
| Fssnoc2501 |
Strat81, When you say won't turn over, what do you actually mean? Will the motor not move? i.e. locked up this is very bad. Or, won't fire up or catch? This is much easier cheaper to fix. If it won't fire up check first for fire from plug, (you've done this), then check if fuel is getting from tank to carb, (this is done by disconnecting fuel line and making sure that fuel flows easily when valve is on), if not,Then check if tank vent is kinked can occur easily especially if you have a tank bag open the gas cap if fuel flows then hose is kinked, Then check if the rubber boot between the carb and the intake manifold is cracked (if this occurs creates a serious leak with lean condition that will create not firing up) If all else fails buy a new plug they are cheap. If none of these work and no one comes up with other easy to check items, I would seek help from the dealer. If still on warranty and not 3-4 hours from dealer (like I am) seek their help now.

Strat81, I had this same exact problem with my Blast. It died popped and sputtered, then died. I replaced the spark plug, which was fried, and it still wouldn't fire up. I found out that the intake was loose on the head which was sucking air and bypassing the carb. Meaning that no fuel was getting to the cylinder. I tightened that up, and it ran fine. I've been golden ever since. I've had three seperate proplems like this, mainly due to the engine just shaking everything loose... --Jim | ||

About a week or so ago somebody was saying they were dragging their rear sprocket on the ground in tight right turns and others here were telling him it was impossible. I'm here to tell you it is possible!! I was riding my wifes Blast yesterday and almost crashed when the same thing happened to me. Rear tire just lifted off the ground and luckily I'm stout enough I was able to do a dirt bike kick and bring the bike upright before i crashed. Wasn't really sure what had happed until I looked at the sprocket and saw a nice set of gouges in the sprocket. The damn thing is plastic!!  | ||
| Aaron |
Just that cover is plastic. It holds the belt on there. | ||
| Buelliedan |
Aaron, Thanks for the heads up. I sure wish there was a way to put a smaller sprocket on or a thinner design available. | ||
| Dansherman |
I'm still suprised that people drag their sprockets. I've had my bike wayyyyy over, and haven't touched it yet. I just looked at it though, and there are some scratches... hmm... I think I'd notice if I hit it. Maybe not.  On the aircleaner issue - I think I'm going to make a copy of Tony and Ray's design. Maybe I'll make some modifications to it, who knows. For now, time to watch a movie. -- dan | ||
| Blasterd |
Greetings everyone, I am At the rear-tire changing point & I was wondering if anyone had any idea on how wide of a rear tire can you put on the blast? thanks in advance, Ken  | ||
| Sarodude |
Wasn't it determined by XGeck and friends that the sprocket cover won't touch unless you lean the bike PAST the edge of the tire? -Saro | ||
| Xgecko |
Something to think about I don't use OEM tires...different profile |
