We should have a thread dedicated to little questions that don't deserve their own thread.

When I start my bike it jumps to life happily and promptly with the CVK34s. When I place my hand behind the exhausts when idling without choke there's some real force to it, I can feel it pumping out that burnt fuel. However when I get back from riding when the engine has reached it's highest temperature while riding the exhaust pressure feels like it's sputtering out in comparison.

I tried some quick google searching and snooping around on the forum and turned up nothing. Is the normal behavior?
 
check your valves. could be too tight. When all that metal gets hot and expands, the clearances close up.
