Yep..I finaly did the conversion of the MULLET over to an OSD set up. WOW is all I can say...what a major diff in the feel. Well ballanced ( no mass spining parts on the left side) and a bit snappier to. Think I freed up some HP from loosing the crapshaft.
As for the left rearset sticking outward 3 inches...its nothing. I did not even notice out untill I thought to think about it. Causion to the ped thu when moving the MULLET around in the garage. YEP cought my calf a few times while I was still in shorts.

ALL and all if your going to run a fatty ....go OSD 330....king set up all the way

To save posting and hosting and reposting...here is a link to the conversion work with pics from my BUSA forum im on. Hope this works.

Thanks for let me know that. Guess Ill find time to host them to Photobucket and then here. ITs a loss with out seeing the pics.
The OSD came staight from Kosman....and the OSD outer cover ( is the support plate ) is also the bracket for the rearsets. The end of the plate mimicks the frame where the rearsets bolt to.
Ill try and host pics tomorrow for eveyone.
Right now my 3yr old boxer is beging for my pop cycle...so I have to go.

That would be great LEE, THANKS. ITs a lot of pics to put on Photobucket then repost them here.
MY orig write up was over at ExtremeBusa.com....but I know none members there would not see it, so I tried the one from Hayabusa.org.

THanks again LEE if you can do that.

BigRod - quoted from Hayabusa.org:

Many you have seen my threads about the jackshafts blow out its bearing on my fatty 330. Well Iv had it with bearings, adjusting dual chains, and knowing that the jackshaft is robbing HP from me. SO I went OSD = Out Side Drive. THis puts the chain on the outside of the frame. You will see what Im talking about very soon.

Many of you fatty admirors have seen the OSD set ups that Roaring Toys is selling with the arm and all. Having a C&S jackshaft 330 arm that I LOVE the look of ...Im kept my arm. When running a OSD..the rear wheel can me closer ( less of a stretch ) cause there is no need for room of the jackshaft any more. I how ever like my look of the 9 over that the MULLET is set at now. SO why not keep my arm then.

Lets get started with the write up and pics.

THe C&S arm complet min the removal of the crapshaft ( jackshaft ) cog.

Then I cut off the outer tab that held the shaft and adjustment of the cog and gound it smooth.


Give me some time to write this up...several pics.








After that....NO going back now!
For a temporary dress of the grinding....I covered the area with carbon that I had left from my tank pad I made. Works good for now. THis section later in the winter will be a triangular air tank that LOOKs like its part of the arm with a cover over it and the section of the arm that could have a NOS bottle. More of this later.

The MULLET is all prepped and ready for its new OSD conversion. The billet sprocket cover was taken off and sold to a good home .
The Vortex 16t sprocket was removed and also the left rear set with air-shifter.
Removed the left outer swingarm pivot nut........
and was awaiting the arrival of the OSD kit.
FInaly after 3 weeks and 5 day wait of a 3 day shipping..YEa go figure, its here. THe OSD kit came from KOSMAN. They are the ones that are make it for RoaringToyz. Took some searching to find that out. NO middle man on this one.

WOW...a box of those soft peanuts



As you can see...not many parts to this OSD kit.
Big cover = slave support / LARGE offset sprocket carrier, and chain guard all in one. Yes this billet cover plate has a support bearing in it for the offset sprocket that helps support the outer end of the output shaft.

The second pic is of the back side of this billet support. See the white ish roller thing closest to you. THat gets threaded onto the swingarm pivot rod and is a roller guide for the chain so it does not saw its way thru the pivot rod or the means of mounting this big plate. THe plate is also mounted just like the billet slave support / sprocket cover I had on prev. Thats basicly the concept.





ON with the big offset 18t sprocket.



This cone section slides tightly into the open end of the big sprocket and is O-ringed for secure fit. The cone is then pocketed into a bearing support inside the cover plate. The speed sensor bolt gets put back in this.
On with the roller that mounts to the end of the swingarm pivot bolt. This also is the bike support bracket for the cover plate later.

On with the shifter linkage extension.
The extended support bolts to the cover. Much like the old billet slave support one I did have.
On with the slave cylinder.







On with the Ek ZZZ chain. This took for ever due to me snapping the push pin in the chain breaker just before the rivit was clear out. Cut off 7 pin lengths from the new ZZZ 150 pin chain.

On with the support cover!







All adjusted, rear sets on, HMF cans back on, wheel tightened, and clutch bleed. The coolant overflow tank....WILL NOT go back on in its orig location. IT conflicts with the OSD plate. For now I have move it forward and secured it, but cannt reinstall fairing with it this way. BUT at least I get to go ride and try it out. I have a 92-93 GSXR 750 coolant tank coming from ebay and will try it on the right sideup near the rad and frame. Think it will fit nicely up there.....DON'T KNOW
