muffler choice

I will put a 4-1 Mac or kerker header(they look the shortest) my question is can I put a newer style micron muffler directly to the end of the header? I like the new one for the R6, but don't know if it would flow correctly on the 1100cc motor. I am no exhaust specialist, just know what look I want..... open to ideas...chop

Flow should not be a problem, but noise. The real noise dampening on a R6 is done by the collector box under the engine.

loud is good

I don't mind loud, cars can hear you.....so would any muffler from any newer 600cc bike work, flow properly? i have been looking at a couple on the bay. The 06 cbr600 muffler is nice....

how about this one

Is the lower square box the part you're talking about or is that a cat converter?

That's the box. Do not know if there is a cat on board. 600 exhausts flow 100plus horsepower, the latest even 120. So it should be fine.

So just match horsepower of the donor bike? I have many options then, XSelnt....

well easy:

1100cc x 8500 rpm = gasflow x
600cc x 16000 rpm must be gasflow x too (roughly)

you cannot compare 4 into 2's with 4 into 1's as the gasflow in a 4 into 1 muffler has double the speed as in one muffler of a 4-2,
but I guess you thought about that already

swingarm is done

Custom swingarm pivot bolt attached to stock frame pivot points and pivot bolts.Smooth as Butter. The monoshock is a good fit, but I'm eating my words, I will have to relocate the battery, will be under rear fender. Triumph swingarm mounted with 25mm dia. spacers,1 from the Triumph, 1 from the xs1100 middle drive race bearing, go figure. Will post more pics,when monoshock is done hopefully tomorrow. Decided to go with a solid aluminum engine mount near the sprocket and keep the others rubber(best of both worlds).

Wow, this is looking fantastic, can't wait to see the final result.

mee too

Hey pggg, do you have a sealed bearing on the inner middle shaft bearing on your setup? Obviously to keep the engine oil in. If so then I want two of them.....

[pggg]

Chop one of the bearings is a 25mm X 63mm, can't recall the other, but you'll suss it when you strip the drive unit

inner bearing

inner bearing I.D. is 30mm and the problem is that the outter drive splines are 29.5mm. maybe some are mfd a little different. I want to hard weld and regrind the spline surface to accept the same size bearing as the inner( and find 2 sealed ones of course)

[pggg]

Both bearings are common available size, I get 29.8mm across the splines, sprocket spline pattern is 26mm x 30mm.

muchos gracias

I have found a source for two of these sealed. I just don't know why yamaha cut those splines at 29.6mm (mine). I may be able to just wrap them with some thin mic'd sheet (.4mm) and call it a day....merry christmas
