I have a friend that will make me a custom swingarm and custom A-Arms... I plan on running nos and/or getting the Craycraft 730... What length of swingarm should I have him make a +4 or +6" and will this effect my jumping at all... And would +3+1 A-Arms be a good setup also?

 

+6 swingarm and +2 is wide enough ..

 

Yep. The +6 will keep your front end on the ground when you unlease the power. I don't think +4 would be enough. [img]i/expressions/face-icon-small-smile.gif[/img]

 

You don't see too many people jumping with a +6 swingarm. I have a +2 and plan to bolt on a wheelie bar for drags.

 

I have a +4 swingarm, and nitrous on a 686 craycraft motor. My front end hasn't came up yet on pavement with bald stock tires. Just spins the tires. I'm heading to OK to do some racing at the dunes this weekend so I will find out what happens in the sand. I like the +4 a lot for duning and riding around as well. It handles, and rides much better than stock. Jumping seemed better as well. Of course I don't get big air either. Just enough to scare me a little. This bike is now pretty much 100% drag only. I think +4 is enough, but +6 wouldn't probably hurt you much.
