Conventional wisdom says the cross over increases efficency by allowing the cylinders to share the mufflers, increasing the muffler volume available to each cylinder.

Why are you adding a crossover to a single muffler design?
Am I misunderstanding your use of "cross over" and you mean the same as junction box or "Y" pipe?

I don't know about power, but the crossover definitely reduces noise on the GS.

It also allows the cylinders to share the volume of both headers. Just because a bike has a single muffler doesn't mean that the crossover won't have any effect. BMW put crossovers on both the R100GS and R100R - both single muffler models.

Question Cross-over / joined exhaust effects

-------------------------------------

I noticed they place the cross-over where both headers are the same length. When two exhaust headers with no cross-over are joined into a single prior to the silencer - does one header being longer than the other before the merge effect performance of one jug over the other? How do you 'balance' the effect if it does?

There is the existing crossover at the front, which I'm going to bother eliminating.

I was referring to the "Y" that I made to bring the right side to the left side.

Once again, i invoke what i heard from the the mouth of Paul Rooney, whose opinion it was that the crossover pipe was there for when the bike was at idle. It was an idle assist, for whatever reason.

Thi came up because i noticed he'd cit his off on the R65RR and welded plugs over the holes, and i wondered why. He said it wasnt built to go at idle, and every little bit cuts weight :)

Agreed, I just got the bike a couple of weeks ago aftet years of lurking here and I have to say i'm impressed. I've got a head full of ideas and plans for it...fortunately I have a very good platform to build from. previous owners have done most of the mods I would have. I intend to give it a more "rally" look and the ergos need to be adjusted and it's requires mods to enable it to become a submarine..mechanically wise she runs like a dream.

Extended swing arm
Cams upgraded
Pistons coated
6000 miles on engine
Hpn transmission
Hpn style frame
1040cc
Etc

I feel very spoiled and I'm loving it

I like. Where did it come from? Who built it? Got any close-ups of the frame work? You realize we're not going to let you off the hook with one photo, right?

That's a good enough reason to have it for me. I must be one of those boring BMW guys.

+1 I can't believe that in this day and age people still build motorcycles without telling the world about it on the internet. Selfish jerks
