CB360 K0 Not well

(1/4) > >>

nairb:
Hello, I have had this cb360 for 3 or 4 years and after its restoration have done some 3.5 k on it without any issues....... except for now.

It starts ok and pulls off ok but now won't rev over 5k in any gear.  Seems fine in the lower revs.  SO, before I start to investigate, I thought I would ask the obvious questions......

1.  Blocked main jet?
2.  Ignition Advance not working.? Stuck.
3.  Points gone duff.  Not looked yet.
4.  Some other mysterious and daft issue.

Bryanj:
3.5 k is dounle the service interval for points and timing PLUS points can, and do hort out on the cover

Johnwebley:
Does it have single coil?


With twin leads?

Have you renewed it?

I had a similar issue with my CB200

turns out the primary resistance was to high,
Needed to be about 3.5 ohm

Revs OK now

Well, I have begun the investigation.  Does a cb360 ever go pop.  Apparently so. 

It's a twin coil/points setup.  All original as far as I know. 

So a quick and simple test is to change the plugs.  And with a new set of sparkies I went for a spin.

It's still unwell.  So those points will be looked at next when it's cooled down.  Maybe a set of points from DS is in order.
Time to check the advance units as well.

Oddjob:
If ordering points, I'd strongly advise buying original, not copies. Copies just don't seem to work as well these days.
