HELP, can someone give me some Tech help. I have a 99yz400f and I got on it just a few minutes ago to start it and run it around the yard and 3rd gear was acting really noisy, at first I thought it was the chain jumping the sprockets :) but it started acting like it was downshifting and popping. any help would be appreciated.

Ynot, it sounds expensive? :) :D I have no idea except it will probably require a tear down. :D

Can you isolate the problem to either transmission problems or a cam chain jumping its cam sprocket? Generally, transmission problems should not be related to popping.
