Dirty carbs

It's PARTY time!!!!

New thread to better communicate the planned ride for Oct 07 2023. So Mr.Don, and others, fill us in. Who is planning a route or do we just go our own way. Where are we going? What's the time line? Who buys lunch? or does momma say be home by lunch?

What type of ignition leads did you use? Should be the wire type, not carbon.

Good news bro. We will continue to request more grace. There is lots available.

Did you use the right plugs, did you check the gaps, did you check that they all fire regular like. Maybe a poor connection at the coils or plug ends. Maybe the resisters are corroded. If all that checks out it's back to the carbs.

Having low compression on these bikes is not an everyday occurrence, that is to say it's rather unusual. Let us know that this is how you did it. Kind of difficult to do remote diagnosis. So, 10w40 oil, warm engine, all 4 plugs removed, throttle wide open, then install compression tester and get a reading from all 4. Then do it again but this time squirt some oil into each cylinder just before you install the tester. Make sure to write down each reading as you get it.

Will add her to the concerns for The Lord of lords and King of kings.

First try to refresh the fuel in your tank. Add about 1/2 tank of fuel and 1 full spray can of carb cleaner to the fuel. Not the bottle type, use the spray stuff. Let it run to get warm, shut if off for about 1 hour then repeat 3 or 4 times. Now fill the tank and take it for a ride. If fuel keeps pouring out take the handle of a screwdriver and tap the crabs to jar the floats loose. Maybe it will solve your issues.

Looks real nice!

Glad I don't have that issue, I just get on the bike and ride,,, following my 2 front wheels which can often time get into and argument as to which way to go. When that happens they gave me reverse which has only one wheel and no discussion,,,, unless I have a certain passenger.

If the idle mixture screws are at fault there will be a crease in the tapered end. The taper should be smooth with no lines. Also, on the screw will be a small spring, a small washer and then a special size o-ring. Don't loose any of those. If you don't see or have an o-ring it could be stuck inside the carb, or the washer for that matter. You will need to fish them out or find new ones. Fishing can be fun and just because it doesn't come out easy, doesn't mean it's not there. Use a small LED penlight to look down the hole.

I don't think that will fit an 86up. Only good for 83-85 if I'm right.

Glad you like it and hope it serves you well. May you be blessed enough to enjoy riding for a few more years. It does look nice and shiny!

Take it off, clean real well, let it dry, spray with hair spray and put back on immediately.

Will continue to you two in our thoughts and conversations with our Lord and Master, so that whatever comes your way you will be able to find blessings even though.

How much research did it take to figure that one out?

Seeing as it's been sitting for quite some time, I think you'll find that the rear wheel cylinder might be hanging up.

Two things can cause this to happen. One is that the rear reservoir is too full and when it heats up there won't be enough space the brake fluid to go, so the pads don't release completely and cause more heat. This can usually be fixed opening the rear bleeder screw. Second, there is a weeeee little return hole in the MC and if it gets plugged then the same thing will happen, more than likely your issue by what you said about the white stuff. The ix would be to clean and flush the whole rear system, a lot of work but I think you may have had a puddle of water residing in the system. Do this sooner than later.

Time to get out the multi-meter and a schematic.

Starting a new thread might get you more replies.

You did say 'run' didn't you?

That's what I see as well. Now that is at 175rpm with throttles wide open. 220 makes sense I think.

You can stick around, if for no other reason than for your in-depth MC research and knowledge.

In MHO the left ones are running rich or not getting a complete burn. The ones on the right look good. So that could be part of the issue, but I think there is more hamburger in the pattie, somewhere.
