Where do I find good books or mags on tunning for my kfx 400. Im looking to get into the carb and start working the top end a bit but I dont want to jump in without a couple good reference books.

 

Sandmudandhills you need to go to your local Kawasaki dealer or to Ronayers.com and order yourself the service manual for that KFX 400, that is the best source of info. Make sure you follow it to a tee, especiallly all torquing in/ft. pounds specs.
