Came shaft chain

How do you check to determine if the chain is within specks and what the specks are .

An easy way to determine if the cam chain is excessively loose would be to remove the valve covers, and gently rock the crankshaft (using a socket and short breaker bar) while observing valve movement.
Of course, that method will not give You measurable values, however, it would give You ballpark knowledge as to the general condition of cam chain and tensioning device.

I have a 2004 voluta. 800 that got low on oil , less than a3/4 quart and a taping noise developed . I listen to a motor on u tube that had the same noise and the owner corrected it by replacing chain . Engine has good compression 180 psi. And the leak down test showed a 10% loss. An inspection of the oil pump screen was clean , the oil pump pressure is over 70psi at high idle . The adjuster on the front cylinder is a little slack compared to the rear cyl. My question is can I manually adjust the tension by pushing on the adjuster until it clicks enough to raise the
Other end of the came shaft so that a little hand pressure will seat the shaft into the bearing .?

According to my Clymers manual..

Standard compression - 246.5 - 188.5 psi
Service limit - 159.5 psi
Max difference between cylinders - 28 psi

At 180 psi, you are below spec and just above service limit, meaning your engine is worn. The 10% loss on the leak down test is indicative of needing an upper cylinder rebuild.

There is no manual adjustment on the cam chain tensioners. If the front chain is slack, then you need to replace the chain and tensioner. While you're at it, replace the rear as well. This is of course in addition to the work needed on your top end.
