Oh, just that there was a type of plug I tried once that caused a huge amount of backfiring on decel, and I know of someone else who used the same plugs and had the same symptom. But it wasn't an HD plug, nevermind. AW | ||

Anyone know of a Bub's installed on a Blast? If not, you'll likely find out soon enough... I would, however, like some feedback if anyone knows anything about 'em. I bought one on eBay for $150 or $160 used for about an hour (probably a dyno comparison pipe for a manufacturer or something). IF I ever get my bike back, I'll be trying this one out... -Saro | ||

I just bought a 2002 grape juice Blast. This is one of the finest machines I've ever riden. I also own a 2001 FLHT and the Blast is as much fun to ride. Are there any Blast riding clubs forming? I enjoy this site. Keep up the good work! | ||

Bub's Pipe = LOUD. Don't tell my wife, but I believe it's louder than her V&H. This is the one I got for $150 used - allegedly for only 1 hour. It was either a dyno test comparison pipe or the guy got tired of listening to his brains vibrate into mush. My motor is still pretty fresh (a touch over 100 miles) so I can't really tell you what the pipe feels like. When I get the carburation sorted out I'll post some impressions... -Saro | ||

Saro, The Bubs pipe is black isn't it? On a aestetic level, how does it look? All the other pipes I have seen are either chrome or aluminum. (As I have stated before, I like chrome and it can be absolutely stunning. Just as long as it is on someone else's bike, because I'd rather spend my time riding and not cleaning.  ) I hope you get some good results, because I'm looking at a pipe this winter and the Bubs was top on my list. Either that or maybe a complete fabrication of a pipe. A straight pipe could be pretty intersting. What I'm really looking forward to is what "King Blastard" a.k.a. Mr. Wilson has done with his pipe, top end, carberator, etc... should be intersting. Jerry | ||

Jerry- It's definitely black. It's got a relatively small conical muffler that makes me wonder how much muffling it could do. At least the V&H LOOKS like it has some muffling guts! I think the Kerker is black except for the muffler. Ray? Initial impression: Kinda feels like the dip in the torque curve is gone. Like I said - still trying to be nice to the new motor so I can't really say. Here's the Bub's Buell Page: http://www.bubent.com/makes/harley/buell/index.html I'd really like to hear some dialog about the different exhausts out there. Seems kinda quiet (lame pun unintended)... -Saro | ||

Saro, Yes, the Kerker exhaust other than the muffler is black. The muffler is a 4" cannister type (internal baffle with packing) made of aluminum. I have found that keeping it clean is quite easy using S-100 (spray on, minimal scrubing, rinse off with water, wipe dry and go riding). They main concern that I have is the groung clearance that it provides (which ain't much)although I have some scars on the bottom it is holding up well. I plan to replace it with a 3" offroad supertrapp which is black when I wear this muffler out. The advantages are smaller diameter (more ground clearance), black (looks good), tuneable (disc technology)and adjustable noise level (again disk technology). The Kerker muffler is not unpleasant unless you crack the throttle betrween buildings. Also, it ought to give that reverse megaphone exhaust look of thumpers of yesteryear. Just installed a Kerker on Dad's Blast and he's very happy with his also. If you install an offroad supertrapp they are held together with a single center mounted nut. I plan to use a combination of locktight, nylon lock nut and safety wire. (I hate to have to stop to work on my bike when I'm out riding ) Ray | ||

Bub's pipe updatetta- Since I received news that the motor in my bike isn't really the motor that's supposed to be in my bike and that yet ANOTHER new motor is on the way, I've decided to sneak a peak at what the motor does with the Bub's pipe... Compared to Loli's V&H, this thing GRUNTS. I haven't measured but I believe the Bub's to be longer (before the muffler). The power band is so beefy down low and it's not as willing to hit the rev limiter as the V&H. I'd pick the V&H based on my LIMITED impression. The Bub's is GREAT if you don't want to click down to go. Both bikes still have stock jetting. I'll be trying something different carburation-wise and will report that appropriately. -Saro | ||

Just a thought on the Supertrapp exhausts - Was looking through the pages, and noticed the MotoX mufflers, and got to thinking... most motoX bikes are 4 stroke and 2 stroke singles. Blast is 4 stroke single.... Hmmm, wonder what a high flow MotoX exhaust would do on it ( say one of those Supertrapp 3" IDS series with the race core...) Am I thinking wrong? I know I'll have to custom make a header for it, but if the end result is better, then.... -=] DStorm [=- | ||

For those that want an all black system...D&D's all black full system with black and silver tag Price: $295.00  | ||

OK I have my White Brothers exhaust in my hands and included in the Package is a Torque Valve. I'm wondering if this is something I want to do or if I should just leave it out? Sport twin didn't actually use it when they tested the Eseries pipe so I have nothing to go on. Also wondering if it will effect the sound output for my pipe? I don't plan on installing it until at least friday as I am waiting for parts from Crossroads Performance as well, so I want to put everything on at the same time. | ||
| Blake |
Put it on a dyno and see what it really does. Sounds like the gizmo the Japanese are using to prop up flat spots in the power curve. It effectively alters the exhaust geometry in favor of certain rpm ranges. Does the WB valve tap into a vacuum source somewhere, or is it actuated by exhaust flow? | ||
| Xgecko |
actually it's a collar that slips into the header that effectively necks down the exhaust gases just as they exit the head they expand after pass it. An easy comparison if you know guns is the insert put into old M1 rifles to change them from 30-06 to .308. That's what it reminds me of anyway. | ||
| Rockbiter1 |
so its like the torque cones available for the big twins? | ||
| Xgecko |
exactly rockbiter. Do they work? and more importantly do they make things any louder | ||
| Sarodude |
Tony- There are some Battle2Win dyno charts for the Blast E pipe and if I remember right, the consensus was to use the torque cone unless you're running at Bonneville... I'll try to get more info tonight... -Saro | ||
| Xgecko |
yes but they didn't test the cone and more important it isn't designed for top end like that comment would lead one to beleive rather low end torque. that piece of journalism (the article not the whole magazine) while amusing was both inacurate in it's assumtion and worthless in it's conclusion. I'm inclined to use it if I know that it won't effect the sound appreciablly | ||
| Sarodude |
Tony- That's what I was trying to say... Use it unless you're looking only looking for top end... Somebody tested it somewhere... I think I read something on the OLD SportTwin forums but either I was hallucinating or that message has poofed away... -Saro | ||
| Blastin |
Tony, I can't find any info on the White Brothers pipe on the Sporttwin web site, they are only advertising the V+H for the Blast. The D+D pipe is not listed on Sporttwin, although it is on the D+D site. I can't find any info on the White Brothers web site either. Am I just a nimrod? Or did you get a cataloge from White Brothers? I have an e-mail to D+D and Sporttwin with some questions, so hopefully they'll get back to me soon. So what made you choose the WB pipe? First and foremost I want an increase in performance. Then a close second is sound.(I still want to be able hear when I'm 70) Last is looks. I prefer the black pipe, just because I hate cleaning chrome/aluminum/stainless. I much prefer to spray some S-100 on, hose it off, take it for a ride and not have to look at the water spots.

I got my White Brothers exhaust from a Tucker Rucky catalog I did some reading on the White Brothers website. Something to think about...White Brothers has made their name making exhaust systems for 4 stroke singles. I like the adjustiblity of the Supertrap like disks. I had/have a V&H and while it is/was a nice pipe it is LOUD. Yesterday I amazed two guys on Harleys with the NOISE my little single could produce...I'm tired of that...I'm tired of my teeth hurting from the crack of the exhaust. Good luck with Sport Twin writing back I have mailed them 3 times in the last month with no answer...maybe the address on the webpage is dead. In addition to costing more than the rest D&D is known for being loud. Many owners of import sportbikes have complained of the sound. The Kerker would likely be roughly the same as the White Brothers (and cost less) I just couldn't get around the really weird look of the pipe. | ||

Tony, Just ordered the White Brothers pipe. One of the local moto-sports shops is having a 20% sale on just about everything, including special orders. The sale is a promotion for the ARENA CROSS series that's in Milwaukee this weekend. I'm going to the races tomorrow night, should be a good time. So I got the pipe at just about the V+H and Kerker price. Shipping should be less than 10 bucks. Today is a good day. WhaaaWhooo Now to start figuring out jet changes and the like. What has everyone else been doing with jet changes?(I hate to reinvent the wheel) Jerry | ||
| Xgecko |
45/170 is pretty much what most folks do as a start this is also what Battle2win used in their test of the WB pipe. | ||
| Xgecko |
Well I couldn't stand it...though I wanted to put all the new parts on the bike at the same time the V&H just had to go Taking everything apart was easy though mess since that pipe has been on a while and the blast need a bath...badly. Anyway took it all off removed to old header gasket and put in the new one (not easy to do with out screwwing it up). The other annoying thing which I recomend replacing if you can is the Jesus clip on the end of the header. It took me 5 minuted to get it off and another 10 to figure out how to put it on the new header. A new clip would eliminate one of those steps and they can't be expensive. Then came the begining of the puzzle. While White Brothers is real good in their directions telling you how to tune the pipe they ain't so good about tell you how to install it...actually the directions were OK but the photos were pathetic (which from a photographer's POV is a sin). It took me a while (including a look at both Battle 2win and the white Brother website) to figure out what went where as far as nuts and bolts but I everntually did. I also left a peice inside the house while I was doing everything which really left me scratching my head (there is a little L shaped bracket that is the rear exhaust hanger without it nothing bolts together). once I figured it all out (and had all the parts it went on quite easy and I did install the torque valve. As for the sound...very very quiet at idle; so much so that my wife was smiling when I returned from my test ride (ya gatta take a test ride when you do something new to the bike). Gone is the CRACK of the V&H, it still thumps a long but in a much more pleasant manner. Decel has a whole new sound but no popcorn. The hesitation that it used to have at about 3k is gone as well. After Aaron's discussion about back pressure I've got a pretty good idea what was causing that anyway. Seat of the pants it feels about the same as the V&H. As for the V&H, well the header looks OK but it needs a beed blasting...the muffler looks bad on the bottom. I guess I've scuffed more speedbumps that I thought, and it needs a repacking so I may just clean it up and hang it on the wall. | ||
| Blastin |
Tony, Did you think the Tork valve is worth using? I just picked up my pipe yesterday, and I was wondering what you thought. If you don't mind, I may tap your experience for when I do change the pipe over. It won't be anytime soon, I'm going to San Diego next week for some R+R. Then its back home to make the home stretch for work on my masters project. Jerry | ||

Have any of you dyno'd or used the Force? How about the Bub? I'm getting one or the other for my girlfriends new Blast! If you've used the Force, does it have any flat spots or dips in the HP curve like it does with the twins? How about top end? Dave Frye | ||
| Xgecko |
For what is worth The Force is tuned for the top end the Bubs for the bottom. Both are Drag style pipes and are LOUD | ||
| M2cyclone00 |
Loud is good! I'm running the Force on my M2. I love it, sounds great. Lisa wants a loud pipe on her Blast! I wondered how throttle response was with the Force at lower rpm. The torque on my M2 drops rapidly below 3000. If you open the throttle at much below 3000 it doesn't respond well. The torque increases from about 54 at 2500rpm to 75 at 3000 to over 92 at 3900 without baffles. Pammy put a Force on her big 88ci X1 after they dyno-tuned mine. But I've never seen a dyno of a Blast! with a Force or Bub. I'll probably go with the Force without further info. Thanks. | ||
| Xgecko |
Drag pipes have a Window of power so to speak (at least this is the way I understood it when Aaron was explaining it). There is a RPM range where they act at their optimum. However there is also an area in the powerband where they are counterproductive. One thing I know about the Blast is that a loud pipe on it can get very irritating. The tone is about an octave or so above the M2's making the note a bit harsh on the ears/teeth. I'd go with a Kerker or White brothers personally | ||
| Blake |
A two into one header, like the Force, helps to smooth performance over a wider rpm range compared to a set of straight drag pipes. |
