    maybe i'm old school or something but i like the dual shock dual muffler look.

    it maybe a deep seeded need for symmetry :freaky

    I too have a need for symmetry. However, putting the exhaust on one side and having the final drive / swingarm on another ... seems to satisfy this urge.

    What really warps my melon is looking down at the two juggs. Sometimes I'd like to give that right jugg a swift kick to put it in line with the left one. :huh

    It does screw up getting the exhaust lengths equal. I forgot to account for that until after I tacked up my crossover. Effit. I'm leaving it like it is.

    I wanted one muffler 'cause the other side is getting a mount for aux. fuel or tool carrier. These little weak motors don't need two exhausts.

    I see this one is using a 4 bolt final drive. On StephenB's para to mono conversion he used a 4 bolt final an had to machine 21.5mm from the inside of the hub to move it over towards the right side of the frame.http://www.advrider.com/forums/showthread.php?t=235926
    Where i'm heading with this is that means an 1100 hubb may work on a 4 bolt mono final drive, enabling a disc rear brake to be fitted :D
    Hard to tell without a final drive to play with but I picked up another 1100 rear wheel cheap of TradeMe (NZ version of Ebay )
    Just in case !! I already have 2 mono swingarms. Just got to keep accumulating bits eh !

    Hmm, two mono swingarms, two wheels, accumulating bits. Maybe make two, sell me one, defray costs? Not that I am allergic to doing my own work but having a renowned expert to work it all out for me? :D

    Thanks:D Ya just never know, flattery may get ya somewhere. :evil mind you, you need two driveshafts to make a long one.
    I just need to find a 4 bolt final drive to play with to prove or disprove a theory.
    In the meantime the bike is being put back together as is as I need something to ride. ( the frame broke on the DR :cry )

    Yep ... It appears that you and I have the same affliction. :evil

    I have two mono-swingarms (unlengthened), three shafts (two of them ARE lengthened), one rear para GS hub (already machined), and one more hub on a GS. I'd really like to get those swingarms lengthened ...

    I've almost completed my preparation for the Airhead Apocalypse. :lol3

    EDIT: The bike you posted ... there is a spark arrestor on the tip of the muffler ... anyone know where I can find one of those?

    eBay. It's this fantastic website where they sell EVERYTHING. :D

    Seriously, that's where I got mine.

    Here's my conversion to single muffler. Next up is to weld the mounting tabs to the subframe and bolt the muffler in place. Then finish the hookup to the crossover I made.

    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.
