Automatic down shift
 

I have a KLE 400. Imported to the Philippines from Japan. Question: Do any of you guys have problem with the motorcycle down shifting on its own? It's quite convenient when on forth gear and it goes o third gear after you let the throttle off but quite dangerous when in second gear on a steep gravel slope and it down shifts to neutral.

I also have a click click sound when it's cold. I know its impossible for you to figure out what I mean with "click click sound" but if you have had it you might know what I mean. I've checked valve clearance twice but still have the same sound. Any ideas ?
