Honda 1982 CM450C Tapping sound

[Grimzella]

Hello,

I was wondering if anyone could help.

My engine seems to tap most noticably after it is warmed up. i did adjust
the valve clearance as stated in the clymer manual (intake 0.08 - 0.12mm
exhaust 0.12 - 0.16mm) and also adjusted the camshaft chain tensioner as
described in the manual..my question is how do i tell if it is the valves
tapping or something else tapping in the engine like .. the balancer chain
adjustment that is on the right side engine cover.. the little screw cap
(inspection)this is a different chain than the camshaft chain.

thank you for your help,
dave

How many miles has it done?
Those Dream based engines had the camshaft running directly in the
head without shell bearings. The bearings wear and the camshaft
rattles.

Beware of over tightening the balancer chain.

It's tapping because it's tired of idling around waiting for you to
ride the damn thing!

Use a screwdriver as a stethoscope. Place the "working end" on the engine
and then put your ear on the handle. Keep moving the screwdriver around
until the sound becomes distinct. This will get you to where the noise is
coming from and then you may have a better idea as to what is making the
noise.

Good Luck.
