EZ has posted a 'Links' page and there are dealership reviews elsewhere on Badweb.

The Problem: Badweb is supported by sponsors. To have a list of vendors would negate that sponsorship.

We have many fine sponsors who do good work and give good service. Please give them a try.
If a vendor sells something that isnt sold by our sponsors then its probably in the 'Links' listing and its perfectly fine to give them a plug here.
I for one dont mind spending a few extra dollars to support those who support us. Mention Badweb and many will go out of their way to help you (if they dont already) and many will give a Badweb discount (ask).
You may also have seen many vendors mentioned that may not be sponsors that seem to contradict the policy. Thats mostly because we're 'lenient' or missed it altogether.

Sorry 'bout that Erik...I didn't think that through very well...and the intent was to find reliable vendors, not always the lowest price...I for example do not work cheaply...as a wise sage once said...quality, price, service....choose any two...although it is tempting to buy low(er) when there is a huge difference in price for identical products.

I will check out the sponsor list and by all means buy from one of them whenever possible. I just finished doing a primary oil change, chain and clutch adjustment today...and the stock exhaust is so in the way, I wanted to create a new sub-model..the "Blast Furnace" I finally finagled the drain plug out, but it took over an hour to get it started back in.

TODAY I will order an exhaust from somewhere!!!

When I've had the stock exhaust, I would just leave the plug on the bike and clean it up with some braklean. I figured if it wouldnt come out, it wasnt going back in!

I will have the Jardine w/QMI module in a week or so...found a local vendor to deal with...I am a big fan of "keep it local" when possible...

Reports on fitment, etc when they become available.

Cheers : )

Use the stock lower front hardware - buy new if yours is old - outlay - 5 to 10 bucks extra and worth it!

Hi, I’ve Been trying following Badweb for some time and think the advice handed out is great! So here I go asking...

I have been riding a 2007 Blast, my first bike and have put 11,500 miles on it. It has been awesome and I know little about bikes. However, last weekend I was about 300 miles from home when the header pipe split clean from the muffler. I got an emergency weld right on the bike and continued to ride up into Canada. Even farther from home the exhaust studs on the engine sheered off. So, to say the least I have a lot of repairs to do! However in fixing things I figure it might be a good time and good mileage to upgrade exhaust? So I am wonder if it is also imperative to switch the jets out at the same time? I am tightly budgeted but not worried about speed or punch as much as just riding! And reliability. I have about a week and a half to situate things before I plan taking this great little thumper on a much longer excursion.

Thank you in advance for any answers or suggestions!

Jets will be around $12, much cheaper than the exhaust. Sounds like your muffler mount bolts were loose.

Jets are cheap and easy. I usually pay about $3. You could get away without doing the jets, but it seams pointless and a gamble. If you're running to lean, your trip will suck (or worse).
45 slow/175 main should be good.

Any stock EVO Sportster or Big Twin exhaust gasket will work.

I havent had any problems with my nuts.

thanks

i just got the exhaust all sealed back up. sporty gasket and nice big chrome clamp did the trick. i got new nuts just because i could. i'm gonna carry a torque wrench and socket for when the gasket seats.

next is rejetting the carb. . .

The culprit may have been discovered. Because of the recent history of my Blast having been stolen and severely abused, I have had limited knowledge of what sorts of things have been missing on this little motorbike. One of which I think may be partly responsible for the recent destruction of my exhaust muffler header. Upon replacing the exhaust and looking at what was on the bike, I discovered that the exhaust gasket was missing. It just wasn't there. So maybe this led to excess vibrations and wear to the muffler header which ultimately led to it's destruction during my last commute back from Oakland.

It's just one of those things you don't ever actually look at on the bike. How often do I peek down and look at the junction between the cylinder and the exhaust? There's just nothing there to normally warrant my attention. Fortunately, an exhaust gasket IS the one Buell part that the Novato HD Dealership DOES have in stock. Wow! Maybe because it's the same piece that goes on all HD vehicles and has been in use since the 1980's.. I understand why dealerships don't carry everything in stock, but it would be nice to go to a dealership once and a while and have something Buell in stock... I got lucky this time.

So the bike sounds good now. I'll take it for a ride tomorrow and test it for sure. I think that overpriced $5.78 piece of crushed aluminum foil might actually make the exhaust last longer than 7k miles this time around! And that's all the coupler really is. It's machine smashed aluminum foil. I probably can make one myself for the next time I need an exhaust gasket. It's good to have the little Blast back!

Oakland to Antioch isn't so far - now that 35 & 1 are no longer my back door - I must more deeply explore the East Bay area - though I did cut my teeth in wine country - lol
look forward to meeting all the East Bay Blastards!

Hey, how is everyone? I am new to the blast and the forum but have been reading and learning a lot. Its a great place. I have a question about installing a Jardine exhaust. The head pipe on my stock exhaust cracked just after the clamp holding it to the block. I bought the Jardine as a replacement. Questions are:
-Should I replace the gasket to the exhaust port? It is pretty well crushed from the old exhaust but doesn't appear to be damaged. If I do replace it how would I do it?
-Since the old pipe cracked, should I look for any issues with the bike that might lead to the new Jardine pipe cracking also?

Thanks for your help.

Welcome to the board!

If you can get a good seal, it's up to you if you keep the old gasket. Best advice is to change it. A flat blade screwdriver is what I used to get my old one out.

The biggest cause of exhaust failure is mounting hardware coming loose. When the whole assembly is rigid, the exhaust pipe rides with the engine. If one nut comes loose, things start to vibrate. A missing nut on the head can lead to sympathetic vibrations in the rear mount, ultimately resulting in a broken bracket. A loose nut on either mounting point will cause the pipe to break.

Use the stock or buy new stock lower front hardware to mount it there - Do Not use their front lower hardware to mount it at that point.

If I cant get the stock hardware locally will stainless of equal dimensions work fine. I dont recognize the symbol on the head of the bolt I took off the lower front connection. Is this a close tolerance or heat treated material, does it matter?

Also, what about locking the hardware? Is there a torque spec for these connections or do we use locktite or safety wire or what?

Thanks for the quick help. This forum is part of the reason I chose a buell, specifically the blast.

I'm specifically talking about the center spacer and rubber bushings - total for the hardware is like 10 bucks max. and worth every penny for vibration protection.

"If you can get a good seal, it's up to you if you keep the old gasket" Concur! Better to replace it, but you can get away with it.

Any bolts will do. Loctite helps.
I use nylocs on the header nuts and a combination of Loctite and anti-seize (done carefully). Safety wiring isnt a bad idea either (drill the nuts or use locking tabs). I mark the nuts with a black dot so I can tell if they move (after retorque).

A repair manual will give you the torque specs and special tightening sequence.

Caution: The use of Loctite on the exhaust header nuts can cause the studs to be pulled out from the head when you undo them. Also the studs are prone to breakage (usually in the 'rust belt' states). It should be used sparingly if at all. I generally use it to keep the nuts from backing off-put it on after the nut is threaded.

EZ-If you find a builder for your pipe, maybe making a third (for me) might cut down on the cost. (I would like an estimate first though!)

I got the same request from others - Give me some time though - I just moved in the house I bought, and I've been working on it most every day in 90 plus weather, taking an hour per day to do other stuff, tearing apart a bike or ride - working like a dog on the house - still unpacking as well, and waiting for the AC condenser fan motor and stator to arrive so I can install them and have AC before the heat kills me at night while I'm sleeping - lol - believe me its on my list - I really like that system and think it should be duplicated for others. I'm in the perfect town to hunt down a local shop that would do such a thing inexpensively, just need the time to do so - lol - Don't worry guys you are definitely going to hear something on the topic soon - as far as a quote goes, because I'll need the duplicate with the added extension length added on for my own projects.

Could someone answer a question: On a stock exhaust at the rear are both side spacers the same length?

Thanks

I found a posting on YouTube of a Firebolt with the muffler off ("2005 Buell Firebolt NO Muffler"). The idle sound that is produced is heavenly. I don't know if 2 cylinders is a requirement for that, but can that be replicated on a Blast? Would straight pipes achieve that? It just sounds so great. The idle has that perfect slow popping deep sound. Mmmmm.

Yes, I do believe the spacers are the same length.Cant check until next week though.

Toni: Yes & No. The idle wont sound quite the same with one cylinder and the sound can depend on pipe size and engine modifications/specifications. You can get it to sound pretty cool though!

I recently did some work on the exhaust and the spacers that hold on the back of the muffler via the bracket are not the same size. I am certain of it. I don't remember which side has a larger spacer, but there is a difference.
