I guess 7 layers of carbon fiber are pretty tough.  I pulled the wheels to get a set of Metzler M3s mounted. | ||

How stable is that with only string to keep it from tilting, and did you have to fab the cradle yourself? Removing both wheels at once on my Firebolt is an...interesting...display of ingenuity, given what I've got in the way of hardware. LOL Rotating the engine down is even more amusing. O_o | ||

Hey Jerseyguy, Sup Buddy...Thats a really niceeeeeee Exhaust Muffler, Ya gotta like that!!!! You gotta start spending some Coin on that ride in some Custom MAchine parts,I`m sure Mike can help ya out in that Dept. Then again I see ya got another Toy in Da Garage...!Always places to spend Da Bucks. May the Force be with Ya...! :-) | ||

Nice bit of carbonfibre, Steve. I might have suggested Dunlop Qualifiers instead of the M3's . Handle a lot better. Know from experience. Keep up the good work. | ||
| Jerseyguy |
Darthane - the string isn't necessary at all as it's very stable. I just slept better knowing it couldn't fall over onto the Porsche. I did make the cradles to fit the Drummer SS line of mufflers. Hogs - You can't tell but there's a one off titanium shift lever on there. Hey, can you see the '66 BSA 650 mill in the back against the wall? The rest of it is in a bunch of boxes. It's my latest nightmare. Jon - Thanks. I'll let you know what I think of the tires if it ever stops raining. I might have a track day coming up. | ||

My only concern is doing that after a few good heat cycles. I've seen Two Brothers carbon fiber race cans get real weak after a summer of riding. The carbon is pretty heat resistant, it's the epoxy used that looses after a while, I also know how carbon does after exposed to UV after a while. The guys I know that work for Delta have to replace carbon fiber after minimal exposure. I'm not knocking the Drummer, just the use of carbon fiber as a muffler material, especially under a bike. In my opinion carbon fiber can't be beat for body parts, just worried about the use in mufflers is all. Please take this post as intended. Any information as to what epoxy is used? Prepreg CF? Autoclaved? Thanks in advance Jersey, for any information you can give. I know Kevin and y'all do your homework, and have seen a reject catch can first hand (still can't find one flaw!) so I know first hand the attention to quality y'all have. It's just I think carbon fiber is getting to be highly over-rated. | ||

Well... At the least we know how well Kevin stands behind his stuff. I think Steve has been testing that one for a month or more now. Not sure though. CF is highly over rated as a bling part for sure  , but IMO it's worth the weight savings in that spot. It's a good deal lighter than the stock can. The only thing I worry about is breaking it and having it shred the rear tire. Broken CF can be VERY VERY sharp. | ||

I have seen first hand Glitches concerns , you do not want to neglect the "repack maintenance" on traditional CF cans. On another note , I have never seen 7 layers CF used , I think Kevin might be standing alone in the industry in this department. Some of the cans Ive seen or repaired are 1 to 2 layers thick.  Go Drummer | ||

As far as the exact materials used, I'd have to ask the manufacturer. He knew it was to be a muffler shell. I have about 600 miles on it now and some of it in quite hot weather and I haven't babied it. I haven't seen any degradation yet - I've been checking regularly. It is generally quite cool to the touch after running. I've also convinced myself that it's quieter than all of the other drummers. I've checked the A/F ratios on the street at length and reviewed them with Kevin. The performance with the race ECM & K&N is just where he wants it. | ||

At the least we know how well Kevin stands behind his stuff. Never ever been a concern! Kevin's reputation was earned, not given. Seven layers of Carbon Fiber ain't much really, even with Kevlar in between every other layer, you're still only looking at the same thickness as about 10 layers of heavy paper. Thanks Jersey for the information on your testing. I'm just a very curious person when it comes to stuff like this. Especially when I've got experience in dealing with CF, I was just wondering what might have been done differently with this that others haven't done. And thanks to everyone for taking my post in the spirit I meant it to be taken. | ||

Glitch, no offense taken. The last thing we'd want to do is to produce something that wouldn't hold up. The closer you get to the edge in design, the greater the possibility for failure. That's exactly why we are road testing it extensively for both performance and durability. | ||

Jerseyguy Would that be a BSA Lightning????????????? | ||
| Jerseyguy |
Freezer - Yes 1966 A65L (Lightning) for the frame. The engine was made in March of 1970. The two Lightnings (Buell and BSA) aren't so philosophically different considering the eras they were created in. | ||
| Freezerburn |
I agree on the philosophy. My dad just fully restored his 441 Victor Special. It was just finished a couple of months ago. It was the bike I first rode on the street, and took my road test on. I guess it would share the Uly philosophy. It's funny how the right foot shifting never seems to be a mix up. Just jump on a Beezer and do the righty shifting - no problem. Did you rid the A65 of the Lucas? | ||
| Freezerburn |
Oh yeah, my dad's got an '02 Boxter S. Funny that. | ||
| Jerseyguy |
Sounds like your dad & I would get along. I plan to replace the entire electrical system with a modern electronic one. I just rebuilt the Amals but I'm thinking I'll replace them with Mikunis. It's going to be a bobber / English Cafe' racer. | ||

if you are concerned (im not knocking, you have very good reason and basis to ask questions) i will help test a CF drummer, hell i'll pay for it. i work at a harley shop so i can put it on the dyno and test it. NO PROBLEM!!! lol i just want one. but seriously i get 1st dibs on the second person to test one. | ||
| Jerseyguy |
Sorry bro, the testing is all done, other than long term durability which I'm doing now. |
