Both of those things are possible but a few more details might be helpful. Is it a recent rebuild or still basically original? Have you been doing any maintenance and is the noise new or has it been 'building' for some time.
How did you set the tension this last time? Sometimes more info is just better. L

Pistons and valves, but new cam chain? Either way, the bottom end (crank) should be rotated first in the clockwise direction and then a bout 1/2 rotation in the anti clockwise direction. This puts any chain slack on the side of the tensioner. You can then set the tensioner. Also do you remember inspecting the tensioner pieces upon assembly and were the parts working freely under no tension. The 150 seems less susceptible then the 160 in my opinion as the tensioner is more robust but there are more parts to wear on the 150 than the 160.
Was the intermediate wheel in good condition? I hope to hear from others on the subject.

cam chain
thanks for all the replies.this is a great information site.i will give the cam chain another adjustment and hopefully quet it down some,dont want to take the covers off at this time as i will be changing the head this fall and hoping to fix this problem first.i did not check the cam chain for being worn as the bike had only 8000 miles but all the pullies were in good shape,did not take the spring out of the cam to see if it was stuck....ps kicking my ass as i am usually quite meticulous..thanks again for all the advice...rob from canada
