Attention Keihn Owners!!!

[mjgnslngr]

We have threads about jetting but most of it has to do with jetting Mikuni or stock carbs. Rise up Keihn owners and help a brother out....
What size / model Keihn ?
What's your mods? Like, no airbox lid, exhaust, filter, bore & porting...
What's your elevation? (easy, google your town elevation!)
What's your main jet?
What's your Pilot jet?

This would be a HUGE help for a lot of us using Keihn carbs. Thanks!!!
