This was a really nasty looking sport tourer that I ripped apart. Built the tailsection from a BMW seatpan, made the fairing shield, made the subframe, molded chunks of the old lower fairing onto the gas tank, dropped the front end, major major major amounts of carb modding and jetting to make it work without the airboxes, shortie pipes with no packing, hardware store orange spray paint.

What do you guys think of my bike with a euro tail on it?

A bunch of Hooligans haha. I love it

OK, so here’s the deal…I am planning on potentially building a new subframe for my SV…for an upcoming tail swap.

BUT, the snag is that although I’d like to build it out of aluminum…I have no one local that can weld it. If I make it outta steel, i have a guy here at work, that is a poet with the welder for steel.

Now we all know for the same thickness, steel is stronger than aluminum….but also heavier. So, what do you gents think of using a slightly thinner wall steel product, versus whatever the wall thickness of the stock aluminum subframe is, to make a new subframe, with about the same strength, but not too much more weight??

Any input appreciated. DZ

So the temporary “tip” (I’ll call it) blew off while I was going to a job yesterday. I’m not sure exactly when it happened as I didn’t notice until I got to a stop light. Anyhow, I made a new, hopefully permanent, muffler. Again, I went to the auto parts store and did it on the cheap. I used one of those short, fat, ricer cans and made an additional baffle/tip with a piece of pipe-adapter.

So here are the pics of the exhaust:

This is the can that I had on the bike up at fighter fest.

Then the next version was this tip I made on the road in Jersey. What I did was hammer-in a pipe-adapter that I cut up and bent in to make a baffle, then slid the chrome tip over it. This fell out because I had tried to tap it into the end of the header, but I didn’t tap it in very far as I only had my little toolkit with me at the time. Anyway, it did it’s job. It got me home and that was it’s primary purpose.

And this is the can I put on last evening. My two main goals were to attach something on the header that would sit under the bike, because that looks kick-ass, and if possible to have something with a deeper tone. With the can at FF and the tip I had made, both sounded very buzzy. I wanted something that sounded less like a mosquito and more like a bumblebee.

I started with a short but fat ricer can, which has some perforated pipe and muffling material in it, but was too wide-open at the end to really do much other than look shinny. I fixed that by making a baffled tip which I hammered into the end of the can. I then used this “muffler-weld” stuff, which looks to be some sort of clay blended with a resin/epoxy to seal up both where I hammered-in the tip, and where the can attached to the header.

Here’s some more detail:

The tone of the exhaust is much nicer now. At idle and low RPM it sounds like a 1000 or maybe even a twin or triple. The tone of the exhaust note raises as the RPMs do, but it’s no longer buzzy which was one of my goals. I’ll probably end-up painting the whole thing flat black; but for now it’s doing it’s job.
