I just got my natty used igniter and signal generator and they all work fine.
Still no fire on 1-3 though but at least I am getting fire through the leads for 1-4 and 2-3 via swapping leads.
An improvement every little bit helps.
So While I had the tank off I figure set the valve lash cos it has been ignored for a while. I got in there and I am certain I did it correctly. Thing is I have one of the old style compression gauges and checked and its wildy inaccurate as it says 180 psi for #1 90 psi #2 No registration on 3 or 4.
Loverly..............thing is it drove like a proverbial bat out of hell before the electrical issue.
So it appears time to get the powerbar out and start popping of the upper engine.
I saw a post in the old forum about using 600 hurricane pistons in the 83-86 gs 550 anyone got some with rings?
I do have a spare complete cylinder. Another grab bag purchase on Ebay.
Ill bet this bike is really powerful when all cylinders contribute to power pulses.
Im gonna cry for a bit and so on, feel free to mock me.
