I have a 2003 Kawasaki KFX 400 slightly modified. (Air box, jet kit, K&N filter & WB Exhaust)
I am looking for information on igitions and Nitrous kits.
I heard that the Dyna FS ignition is the best one to get?
I have not been able to find any good info on Nitrous.

 

A friend of mine has a kfx 400 and runs a procom cdi. His has 3 timing curves one being stock and also has 3 different rev limits stock, plus 1000, and plus 2000. He's run his for over a year now with good results. As far as nitrous goes is you want an easy to install kit that's good for play, racing, and general fun then check out the kit from Boondockers. I've had a Boondocker kit for about a year and my bike still runs like a champ. If you want a straight up ***** out max power nitrous kit then check out NOS nitrous systems. Boondockers system is much easier to install because it is a dry system but the NOS system propperly tuned will make more power because it is a wet system. Nitrous can be great fun but if you get greedy or don't propperly install or tune it you'll be building a new motor instead of enjoying it.
