I bought a used swingarm and have modified it for a 300. I made an end cap for each end of the axle tube, found the center, drilled a hole for a bolt--made a fake axle from some 1" stock and attached to one of the end caps, inserted it into the axle tube and bolted to the other end cap. I got a local fabricator to weld up the notches that I made. He was able to just lay the plate against the fake driveshaft and weld it up, as the 1" round stock is a little larger than the real axle.
I didn't want to cut the swingarm while it was on the bike, so this is what I came up with.
I modified the fender pan --flattened the ridges on one side--I couldn't figure out if it was one or both sides. If someone knows, please respond :). I removed some metal in the front like the guy from Tiawan showed in his pics.
I have a 10" wheel and Avon tire mounted and am planning on starting on disassembly tomorrow. It may take me a while--I'm slow. I have some
2 3/4 bones to install--do you think they will work with the 300 tire?
Thanks to everybody that has posted info about this mod!!
Anything you can think of that I forgot, let me know.

as far as the lowering bones its gonna depend on how well your fender well has been modded.... I had 2.25 bones on mine with a 300 metzler and rode two up and it rubbed the inner fender so went back to stock bones till I can get air ride but then once I did that, the exhaust bracket ended up hitting the singarm so had to shim that bracket out so it would clear the swingarm... but then again I have the DLP swingarm... Inner fender will need all the work and the spacing of the rim between the swingarm....... good luck

Thanks, I think I will put the 10"wheel, 300 tire, and fender on, leave the shock unhooked, and raise it up into the fender to check the clearance.
Am I going to have to remove the exhaust?
Looks pretty crowded in there.
I just removed the covers and the fender and it looks like it would be a lot easier with the exhaust off?

Takes longer than I thought

Got the wheel off, and cush drive changed over to the new wheel. Everything is loose on the swingarm except I can't break the shaft loose that holds on the swingarm. I used a 19mm bolt with two nuts but it won't budge the shaft without turning both nuts. Maybe I will weld on the nuts--that should keep them from turning :dontknow:.
Gotta loosen the exhaust next.
Good thing it's cold, I wouldn't have the patience to do this if it was nice out.
