ok so im now trying to finish up my f2 and i was looking for a few things. needing to get a new petcock and wanted to know where i could order one? and the other thing i was looking to stretch my f2...not by much just like 2-4 inches. all the swing arms i could find were between 6-12 inches though and im not trying to go that big. where can i if at all find a swing arm with only 2-4 inches?

 

You can order one online from bike bandit or cheap cycle parts. You could probably get one on ebay too. The F3 version will work and is cheaper. You just have to plug the vacuum line from #1 cylinder fitting.

Talk to the vendors with the longer arms, maybe they will make you a shorter one for a reasonable cost.
