that thing is vicious man.  love that front end/headlight.  LSL?

Love the idea.
It looks a bit tight between the rear end and the rear tire though...  you sure you'll have enough room when the rear shock is compressed?  Maybe a flatter exhaust would fit better underseat, ala H Comp...

Thanks, but I'm not really concerned about that because I only ride very slow.    Ehm... no, that's not what I meant. The clearance shouldn't be an issue there since on the 916 the exhaust hangs right under the seat. If things get tight I can either shorten the bracket, make it flex to move the muffler further out, or just move the can to the outside.

why don't you use the flat side of the muffler against the motor for some ground clearance?

That was sort of the idea. However getting the exhaust to lay flat is harder than it seems due to where the bolts screw in to the mufflers. I'm still looking for a better solution, some clamps and possibly some carbon cans.

carbon 916 style SBK cans with the strap hangers for them ( possible rebent for repositioning of intended bolting) should be flat/oval enough to give you the clearance in both positions while still giving you the sound and parts availability you'de prefer.

I swapped the cans and this looks like the final layout. Caveat: for the time being...   

Despite the looks there is actually plenty of clearance for the muffler under the engine. I took the bike off the stands and leaned it to the side to about 45 deg and there were about 4-5 inches between the can and the ground.






The two dangling yellow wires need to be connected to the alternator (older 2-phase system) and other than wiring up the Vapor, I'm pretty much done with the electrics! I still need to figure out what to do with the tail light because I really don't love where it is right now.

It sort of sticks out too much... I'm thinking of cutting off the mount it currently sits on and cleaning up the whole tail section... Oh and I need to 'hide' the wiring better, I don't like how visible it is now. Yea, I'm getting anal


Since the wiring is in place I decided to hit the starter. I forgot to video the moment  but this is pretty much what it felt like:
"It's Alive!!!"

Looking good man.

The main thing I'd be concerned with, regarding the exhaust, is just remember to negotiate speed bumps in a way that won't rip off that one silencer.

how are you going to get your pipes equal length?

Thanks, speed bumps will be a concern for a while. I'm still not entirely sold on this exhaust, but I really liked the idea! I'll be on the lookout for some smaller (and possibly oval) mufflers. I also thought about a layout for the exhaust like on the Streetfighter with both mufflers mounted next to each other on the side but I figured the current system would be easier and faster to get setup.

I'll let the welder have fun with that, but the front/horizontal will likely be a bit shorter than the rear/vertical one.

are you using a SBK tail plastic?....if so, why not use the tailights?!?!?!

No, I really don't like the tail plastics (or plastic in general). I'll use a thin sheet of 6061-T6 aluminium, that I plan to wrap around the tail section.

Are you re-coating the frame...?

No, he was going for "bird shit chic"

To do:
- painting the frame
- powder coating the wheels (different color?)
- 944 kit w. new engine bearings
- give the wiring loom a good checkup
- painting the engine (maybe just covers & heads)
- putting in a new hub in the swingarm
- cleaning (painting ?) the swingarm
- new headlight brackets
- redo the exhaust?
- get my hands on an aluminium rear subframe

that's just off the top of my head. Right now I just want to get the bike on the road so I can enjoy some riding before winter comes and I start wrenching on it.

Well done, I am liking your exhaust set up idea.     Had the same similar idea, just no time to get started.

i may swap my aluminum rear subframe for the other ecu type rear subframe, if so, i'll let you know

for the under engine exhaust, measure the suspension travel for full compression (i.e. hitting a bump while on the brakes), find the vertical change to the bike (since forks are at an angle), and take a ruler and see if your exhaust will clear earth still

I think people stress about that too much.  If the pipes end up unequal lengths, just say that's to broaden the spread of torque and make the bike more rideable.

What about danmoto cans? They seem pretty small.
