Hello all. I doing mind mechanical but electrics is far from my strength so I am after some help.

Yesterday after about 6 months ownership and plenty of mechanical work I got my 1980 CB650z out on the road for the first time she’s moved in 12 years. Took it for a spin nice and comfy but definitely a misfire in the higher rpm range and a charging issue to go with it. Done some digging online but I’m now stuck.

Summary.

- The CDI’s (Sparkers) are frazzled and melted.

- After charging the battery, at idle it’s at 12.8V, 3000rpm is 12.6V and 5000rpm is 12.4V.

- I’ve carried out the diode test on the reg/rec and it checks out.

- I’ve carried out the continuity test on the stator plug which goes into the reg/rec testing across the 3yellow wires all approx 0.5ohms and in spec.

- I have checked the stator brushes and they have lots of length left on them to the wear line.

- I have checked the continuity across the slip rings and now is where I have a question. The across the same ring the continuity is approximately 0ohms but across the inner and outer it’s approximately 1/1.2ohms? This seems low as i’m sure I read somewhere it’s meant to be between 4&5ohms? But I can’t find that info again.

What I am thinking is that the generator is the cause of the charging problems and by replacing the generator and the regulator rectifier it will fix that issue. 

Also when riding I noticed a definite misfire in high rpm (above 4000rpm) but I believe changing the CDI’s (sparkers) which are melted and have the resin running out of them will fix that. 

I also noticed a minor oil leak which I believe is either coming from the gear shifter shaft seal or the oil pump behind the sprocket cover, however I’ll get onto fixing this once I’ve fixed the charging issues. I’ve attached a few images below.

Any help is appreciated as I’m trying to work out what’s actually wrong before I decide to strip out and change all the electrical components such as the stator, generator, reg/rec, battery and CDI’s in the hope it fixes it.

Ok I’m at a loss lol
I have been reviving this bike from an old barn.
It’s ring great did a paint job and was finally going to do a madan voyage but the clutch is not working I pull the clutch shift in to first then it jerks and dies does not seem like the clutch is working so I put new clutches in
new oil in the block
New fluid In The slave cylinder pulled the slave apart it looks great and I have pressure
Not sure what else there is to do.
Any ideas??
