At a loss... Solved?

Just re checked the plug on number 4. It's getting spark. It actually managed to shock me after I turned off the ignition.

That header is staying pretty cool, and the grounding strap still looks new. So maybe somehow that cylinder isn't getting fuel?

 

Not being in sync will cause all kinds w.eird running conditions. Sync it and set the mixture screws. Color tune helps for that

 

Cool. Maybe I will try to make the 2 bottle manometer tonight.

Thanks

 

Make a four tube one instead.

 

Any links for one?

 

Supplies:
PVC tubing, 25 ft (I think 3/16 inner diameter, but bring your carb bowl to the hardware store.

Three (2) or four (1) prong "T" connector. I ended up ordering some from granger, but I've seen them in the vacuum testing section of autoparts store.

Two prong tube joiner (4).

2 red straws from spray cans (wd40, carb cleaner, brake cleaner)

ATF-4

Board to mount the four lines to. At least 3 feet in length.

Instructions:
1. Cut the tubing into four equal lengths. Connect using "T"s
2. Mount to board, I used long staples.
3. Make restrictors using the two prong joiners. Cut the red straws in half, then glue them into the joiners. Be sure not to get any glue in the straws. Once glue has cured, cut off excess straws.
4. Fill sync gauge halfway with ATF. You can try to make a funnel and pour, or if you have a vacuum bleeder, dip three hoses in ATF, and suck it up using the fourth connected to the bleeder.
5. Cut 6 inches off the end of each tube, and connect using the restrictors.
6. If there are any air bubbles, make sure they get to the top of the fluid.

 

Thanks

 

I just backed out the mixture screw on number 4 until my engine sped up a bit, and tinkered with it from there. The header seemed to get a lot hotter, and the bike started to sound a lot better. The throttle response was definitely a lot better. Its starting on the first push. Choke when cold, no choke at all when warmed up. It doesn't seem to have that weird loping sound anymore.

Hopefully tomorrow I can get some cash together and build a manometer and get it nice n happy.
