Cognito sells the set for 147 w/o shipping. I just talked to Lance from Sprockets and ordered a 520 conversion 17t/37t for about 100 shipped priority mail, should be here next wed. Once installation is complete I'll update my build page.
I blew a reg/rect last Oct and ended up rebuilding the front end, changed exhaust from 4into4 to a kerker 4into1, rebuilt carbs and a slew of other things haha. Can't wait to get riding agains as the weather in the SF area finally warming up.
now I need to find a 520 chain
