P.S. I have never liked CV carbs. :'(

I don't like them either!! Supposed to give smoother throttle movement.

Back in the real old days, on my first BMW ('68 R50) were two Bing carbs that the body was aluminum and so was the slide!! Those two don't slide! They were a pain to balance as one would stick and then the other! So..I machined solid brass slides. Worked much better!

In fact, it might be good for carb health in general. I have some MMO that I can ad a cap full to each tank. While I don't have the problem, I just may give it a try to keep from having the problem.

I would suspect the slide as well or the carb itself, one of the two (or both) being dirty and causing the sticking. You said it was hard to get out so it sounds like it is in fact sticking in the carb.

However, don't ignore paying some attention to the diaphragm. If you ride a lot ai wouldn't think yours has permanent creases in it, but if something sits long enough in one position it sorta gets a memory for that position and wants to stay there or go back there, etc. I'm not sure what the longevity of the diaphragm is before it gets old and stiff, but any chance yours is just hitting a point in sliding up where the stiffness in the diaphragm is not able to be overcome by the vacuum, and the little bumps are just enough to jog it past that point?

Just a random thought...I have no personal experiences or knowledge to substantiate this.

I use ordinary motor oil. As I mentioned I'm not sure of the long term effects but I am willing to bet it doesn't hurt the inside of the gas tank. Never had any rust on my two stroke tanks.

I've heard it said rubber and oil don't mix, and it gets pretty hot out there in Hollywood

I'll be getting the lucas treatment ASAP.

I am not sure if the small bottle LUCAS sells is the same as the LUCAS stuff I buy in the gallon jug, but I swear by the gallon jug stuff. Every time I have taken apart any of my fuel system (hoses, carbs, etc.) there has always been a little coating of lube - and I never got that from anything else. That's even with the 400:1 ratio! I figure it also keeps the inside of my tank and the fuel petcock lubed as well.

In my car, I get about 4 miles per gallon better mileage on trips than the rating that came with the car. Over 40 MPG. I don't have objective proof , but .....??

I think I got it licked.
New air filter, still did it.
Air box cleaned, still did it.
Carb clean, still did it.
New breather hose, still did it.
WTH? what's left? something you poor SOB's don't have... carbon canister.
Pulled the slide and I noticed a black streak coming from the port.
So I pulled the hose and plugged the port.
Day 1 no issues... we'll see how it goes.

I bet your "breathing easy" now that you found your problem, (ever thought about drilling the gas cap and getting rid of that junk, or do you need it for inspection ?)

Oh....now I get it! Huh

In reading through the thread......it was not obvious to me where the goo could be coming from. Like you - I wasn't imagining a canister on the bike that would become a vacuum operated "goo dispenser".

I have a new gas can... I hate it.
It's one of those spill proof cans and has a spout that you depress to open.
It's too big and just barely fits in the opening.
I can't use it to refill the other cans either.
The spout is too short too and it overfills the tank right up to the bottom of the splash shield.
I'm guessing this has caused more gas to migrate into the canister.
