79 750k Noisy at startup?

[jyd750]

Just got my first cb , 79 750k four, in early dec in pieces
Got it togather and I'm loving it so far but have a couple of concerns
At cold startup the motor is very cold blooded and rattles a bit
Not a full knock but way more than I'm use to (previously I've owned
3 cbr600s and a vfr750 and currently several honda quads)
When it first starts it like its on 2 cyl then after 10 secs or so
3 then in another 10 or so 4 and once warm it as quiet as can be
I'm running castrol 20/50 as I always have with no issues
Bike shows 27k on odometer and seller said motor had 14k

Use the search box (right top of screen) and search "noise at idle" or "rattle at idle' and you should get more than enough suggestions to get you sorted.

Does it get louder, or quite down when you rev the engine?
