I will be receiving my 2000 Buell Cyclone in a couple of weeks and it is totally bone stock with the air box and stock muffler. I see that many companies have very fine air filter housings for it.....but they cost upwards of $400. I just dislike the huge size of it!Mufflers seem to be a choice between the D and D and Supertrapp. Has any one some DYI ideas for removing the stock air box that would be more economical. What about a muffler.....anyone ever modify the stock one or use some other muffler to get a nice growly sound that might be more economical? Thanks Dave | |||

As far as mufflers go, you can go to Advance or Auto Zone and buy a 2 1/2 in and out glass pack muffler for about 40 bucks, get a muffler shop to make you an elbow for one end and a turnout for the other end.Should have less than eighty bucks in it. There are plenty of air cleaners on e-bay for CV carbs and with a few spacers to clear the frame rails, your biggest expense is the KN filter element. | |||

The stock exhaust will give you a nice sound but a flat spot about 3000 ish. Any of the aftermarket exhausts will cure the flatspot, increase your fuel consumption & be much louder. I modified my stock can by cutting through the weld on the end cap then torching out part of the internals with gas before stick welding the cap back on. The exhaust has more of a rasp to it now but is not excessively loud & the flat spot isn't gone entirely but is much less, plus the exhaust looks totally stock. Bear in mind that this is a Euro model with the 2" header. Airtech do a nice aircleaner about $150 ish iirc. | |||

"The stock exhaust will give you a nice sound but a flat spot about 3000 ish" ??? My 2002 M2 has had a Buell race header and muffler with a Mikuni HSR 42 and a Forcewinder intake. Ran great but too loud. Now I have my stock exhaust and a recalibrated CV40 with a Forcewinder intake. Runs flawlessly. No flat spots anywhere. I love the stock exhaust. (I believe that it makes better power in the low to mid RPM range than other louder exhausts.) | |||

As I said, it's a euro model & has a "hole" to meet the noise regs. | |||

Sorry, I missed the Euro model part. Maybe a USA model stock muffler would be a solution. It would look stock and be quiet but it would run very well. | |||

Buell race kit intake is the most free-flowing, but only works if your knee doesn't bang it. I had to change mine. The Forcewinder "bent elbow" thingie is the second best. Both of these have K&N filter. I suspect their superiority is as much the K&N as the design of the intake. The stock muffler is not bad at all, just needs a bit of carb tuning to eliminate the power flat spot. I tried V&H, SuperTrapp, and Drummer, all too loud, went back to stock muffler. After a while, don't notice the flat spot nearly as much as the loudness of the others. It'll still go about as fast as I dare, as it is. Compare these dyno charts, in the Knowledge Vault. The numbers are all very, very close. Main differenc is on the very top end, where mine had the rev limiter set for 6250 (since changed.) His has a Mikuni carb on a bigger manifold. So don't be too fast to start spending money, till you get a good idea what you want.

Tks & great info. Just changed my air cleaner assembly from the Buell Race Kit version as well due to the annoyance against my knee. Installed the forcewinder and will be taking for the first rip this weekend. It's a 1997 S1 Lightning - used to be owned by a local HD dealership mechanic and he did alot of custom work to is - much of which I've since changed to my own tastes. I'm curious what might be the quickest way to determine what kind of carb I'm running? I can post a pic tonight from home, but if anyone has a quick answer I'd appreciate it. Cheers, Sean | |||

If its got a black plastic cap on the top it's a Keihin CV40, if it looks like an alloy brick with a hole in the middle it's a Mikuni HSR42, most likely one or the other, though folk have tried all sorts of things over the years. Just google for pics of them both & you'll know, you can't mix them up. | |||

Much appreciated - I've the proud owner then of a CV40...been looking at that cap for hours while trying to put braided breather lines in place - tight fit and eventually lost patience so went back to the black rubber lines.....for now! | |||

So the V&H for the pre Thunderstorm heads with a nicely flowing intake was supposed to net pretty large gains in power. After 99 when all the bikes got the Thunderstorm heads it was more of a weight saving option unless you want a horse or two on top. There are some links to scanned copies of the early Battle2win magazines where comparisons were done on different pipes where they fairly definitively decided that slip-ons for the 99+ model years were mostly bling... In my 12 years of ownership I can say that I don't/didn't care for the noise (tone and volume) of the V&H on my M2, plus I went from a White brothers E-series (kind of loud and didn't like the disk set up on this pipe) to the V&H and felt a significant drop in torque, I really didn't like that. I've since gone to a Supertrapp. While it can be loud, but doesn't have to be if you're not running an open end-cap or a lot of disks. It's heavy, but not so heavy as the stock pipe, and it can be tuned for flow giving you the best option if you are experimenting with intakes. The stainless Supertrapp polishes up beautifully and mates nicely with a stock header. Prolly my favorite long term pipe. I'd still like to try a Borla slip-on, but don't want one as bad as I used to. Anyway, hopefully the previous owner knew what he was up to and has your carb dialed in pretty well. | |||

I've found myself going back to stock pipes on most of my Buells... Had a Drummer on the Ulysses, sounded great cracking around the back roads but droned something fierce on the superslab. Went back to the stocker with an EBR computer, won't ever change it again. My S2 has had a Supertrapp external disc "trumpet" on it since I bought it. I've converted that bike to Thunderstorm top end with X1 cams and an S1W ignition. I ran a Buell race muffler on it for a while, went back to the 'trapp when I put the race can on my M2L once I found an NOS race header for it, but never really liked the sound of the 'trapp. I finally found a stock S2 muffler...LOVE IT. I need to re-jet, it's loading up just a *little*, but it is SO much nicer to ride this way. Awesome torque, smooth power, and oh-so-quiet...really helps enforce the S2's image as a sexy sport-tour. My S3 Defender is stock and is staying that way. Same for the CR. I do have the Buell race systems on my S1W and the M2L...but they're strictly local hooligan bikes that stay off the superslab so I don't mind the antisocial exhaust as much  I kept the stock setup for the M2L, in case I decide that cushy seat needs longer trips... My all-time favorite aftermarket exhaust for a tuber, though? The Supertrapp INTERNAL disc muffler that was sold through Buell accessories in the late 90's/early 2000's and I think is still available directly from Supertrapp. It was a "performance slip-on" designed to use with the stock header and it sounded GREAT. Nice deep tone, tuneable with the discs, endcap kept it from being blatty. I had one of those on my old '99 M2 and loved it. Good performance, great sound, nice durability, great looks. My all-time least favorite? The V&H SS2R. Loud. Annoying. Cheap build quality (rivets back out or break off, aluminum can mounts break off, packing blows out, internal perf tubes come apart, CF can mounts break in half), and a HUGE torque flat spot even if jetted and packed correctly. Decent high-RPM flow and power...but for street riding? Not for me. Which is a shame, because the V&H products for other bikes are usually nicely done...but the SS2R is just junk. My suggestion for the OP - jet it properly first, and see how you like the way it runs. Do a search for "econo-winder" intake. But spend some time with it before you go tossing money at a muffler change. | |||

Thank you so very much you guys are great! Ok let me see if I have this straight? The stock exhaust is really very very good for making power. As vain as it is I would like a bit more growl!Testing indicates that the supertrapp internal disc setup seems to be the best aftermarket. Both exhausts need some carb tuning to be optimized. Difference between the two is minimal in terms of power. My impression is that the CV carb is very good for low and mid but gives some top end up to the Mikuni HRS 42. Does the Miknui give anything away in the bottom to mid..........causes this is where I will mostly live! It all comes down to economics with me. 300 for an aircleaner for my CV or 350 for a new Mikuni? What filter options are available for the Mikuni? Are there cheaper and smaller K+N clamp on filters for these? Will they support the stock power that an M2 will create? I just hate covering up that engine with a big filter.

I used a universal flange mount 4 inch round air filter from the auto parts store...cut off the flange mount, mark the 3 backing plate holes and drill...that's my $10 air filter. When the paper filter gets dirty I buy a universal 4 inch k & n for another $10. Looks nice and the bike doesn't run any worse then it did with the stock box...maybe even a bit a better as far as the seat of the pants dyno goes For the exhaust I cut off the stock muffler (just after the elbow) and welded on a 16 inch screaming eagle reverse taper muffler I got from a buddy who works in parts @ the HD stealership. The mounting point for the muffler just happen to line right up with the stock rear muffler mount. |
