Re: 1981 CB650c Won't Start

1.Compression test should be done with the carbs held open (full throttle) or better off the bike altogether. 2.Bend the tabs on the floats to get them all sitting at the correct height. The fuel is flowing out of the over flow because the floats are not at the right height. Glad your making progres...

Are you running stock air filter or pods?

Re: Center Stand

Thanks for the exhaust find, Its a shame its not closer to me :( ..

Yes I agree probably easier just to make a bracket for the center stand.

Back to the carb sync's vacume thing, does anyone know what size thread the sync pipe adapters have to be to fit into the pd type carbs?

Thanks

Re: Center Stand

Thanks for the link George. I have seen similar before but just not sure of what to do yet .. I have borrowed a single airflow meter from a friend but its for car use really. The exhaust is the orginal but dented and cut off and it looks bad.. I used to have a mouse issue too in another small shed I...

Re: why would pipes #1 & 3 be cool?

https://s20.postimg.org/46n88amil/solenoid.jpg What are these wires going to? Is it an inline fuse holder with a 30A fuse? If not, it should be. This is not the cause of your trouble (no matter what they go to), but it is something that will need tending eventually. It originally came with a 30A bl...

Re: why would pipes #1 & 3 be cool?

It’s hard to say if the other cylinders are kicking in after 2k from your video just a loud ticking sound can be heard.
Yes timing & compression test is probably a wise move. Remove the carbs first..
Yes the timing is set for all 4 cylinders.

Re: why would pipes #1 & 3 be cool?

Do you have spark on 1&3? Do you have the right HT leads going to the correct plugs?
On mine 1&4 are connected to the left hand coil 2&3 on the right coil. If you turn it over do the plugs 1&3 become wet?
Where a outs are you?
