OK good news. Thanks Voxmagna. I pulled the breather hose off at the block and stuck a long straight hose on the port to outside of the bike. No pressure coming from the block.
I was thinking about my test with the vacuum gauge and decide to check to see where those ports on the throttle bodies came out. Well the ports go to opening just past the throttle plates. Not a good spot for accurate vacuum readings. You really need a vacuum port at the intake manifolds.
I decided to use the high voltage test light I got at Harbor Freight, goes between spark plug and boot. Checked cylinder 2, good spark. Let the bike run awhile with tester on and cylinder 2 was getting warm. Wow. I put plug boot back on plug went for ride, cylinder 2 dead and cold. You can check by checking temp at header pipes.
So I put the high voltage tester back in between and cylinder 2 started running.
I have a plug boot and wire that grounds out when down in the spark plug well.
My test yesterday was using insulated pliers holding boot with plug in it to a good ground and watch spark. Looked good, but plug not in so did not know boot was grounding out.
Cylinder 1 is not as bad but fires poorly.
So using the high voltage tester, cost like 3 bucks, saved me some grief.
Now I just need to order some plug wires. Ain't cheap.
