I have gone round and round in MANY posts about this. It seems everyone has a different opinion on what CAN be done. If you want to know what I HAVE done then send me a p.m.

BTW- You can go up to 200mm without a jackshaft. period. If your swing can handle the rubber. I HAVE discovered some of the secrets of sportbike swingarms by buying them on ebay and will share that info with you as well. A 2007 cbr600 swingarm is taking the place of a 79' dohc swing arm on one of my bikes. I am also converting to the sportbike mono-shock as well. You could use a Yammy R6 swing arm as well with the other style shock system.

Let me know if ya want to see the pics.
