Have a couple older Yamaha sleds ('97,'02)..the redhead triple ones..anyway one backfires on a hot start the other slightly burbles thru mid-range rpm 3-5k of 8.5k I suspect the carbs, Last year ran non-ethanol 91 and Marine Stabil..these units seem to run good..I don't worry they won't start or get me home I want the carbs clean without the time, expense or aggravation of tearing them off then apart..so

What fuel additive or chemical and dose gives me the best bang to insure these carbs are clear?

TIA

Nothing. Cleaning them requires a bit of work. You gotta saddle up cowboy. Suck it up. Only elbow grease is gonna work. Get busy.

I would check the mixture screws, make sure they are the same across the carbs

Usually you can get away with removing the bowls and cleaning pilot and main jets and also remove the air and/or fuel screws (if equipped) and spray in there too with spray cleaner. It's only in cases where the carbs are really gunked up that you need to completely disassemble them. Otherwise, I agree with Phishin, roll your sleeves up and dive in. The best thing you can do is make it part of your pre-season routine. I always did my carbs in late fall, just before the snow flew. They were always clean, so a rinse with spray clean and shop air kept them working perfect.

As for spray cleaner, Berryman's B12 spray cleaner is about the best I've seen so far.

I would not use acetone alone as it will melt some plastics and rubber compounds.

You try this before a carb rebuild:

Another fuel add that has gentle cleaning is LCD's FP PLUS.

I'll try this because it's $3.99 and opinions are it's stronger than SeaFoam which I already have in stock..is it normally available at major auto part stores?

I take it you're looking for something that can be poured in the tank? If so:

http://www.redlineoil.com/product.aspx?pid=116&pcid=12

"Compatible with both pump gas and race fuel, pre-mixed or injected two-strokes"

This is the same thing as their SI-1 product (just a smaller bottle), which is highly regarded and well discussed on the forum here.

Must be able to burn eventually if you pouring it down the carb..wonder why they advise not to add to fuel..toxic?
