exaust note

[jerard]

Hey guys-----curious what you got to say about this.
Almost hate to say it, but the '74 is running perfect ( don't want to jinks it ) I noticed that one of the stock exaust puts out a perfect rythem sound, and the other one has kind of a harley type lope to it. Both are running good compression, no smoke, and singing to red line. Do you think it's a air leak or what?

To check for air leaks, hit throttle shaft ends and carb mounts with short bursts of carb cleaner and wait a couple of seconds; if you've hit a leak, idle speed will change sharply. If you find nothing there, through the basics--resistance in plug wires and caps, cam chain tension and valve lash, point gap and timing, air filter condition, fuel screw adjustment, and carb synch, in that order.

Sounds good--------I've done everything except spray for RPM increase-----I'll give it a go, thanks.

Cam chain tension? Is this a bitccccch to do?

Not at all. For instructions go to www.biker.net and access the factory service manual and owner handbooks.
