Bing 32m alcohol/ethenol resistant float bowl kit

Anyone installed these?
Apparently improves mpg and increases horsepower under acceleration.
like to here your feedback chaps.

That's unsubstantiated hype. Don't believe it.

No mileage improvements have been noted, unless the older system being replaced wasn't operating properly.

A real down-side to this kit is there's no overflow tube in the float bowl. Not at all a good thing!

A good upgrade is the new black plastic alcohol-proof floats you can get for the current carbs. Not sure if they're listed in the catalog yet, and if not, be sure to ask for them. Same price as the white foam ones.

The independent floats that came with a new bowl and no overflow have been around a long time. Although they were claimed to improve MPG through better control of the fuel level no one ever seems to realise that improvement.

I installed one of the kits in 1997, no improvement what so ever, fuel consumption stayed the same, power stayed the same .

I paid around $60US at the time, I didn't think it was worth it at that price, now it's around $130US .

There are alcohol resistant floats available from Bing, they are injection molded plastic, instead of a foam material .

Around $37US for each float .

Succinctly put


There's only one after market thing I would buy and that a translucent float bowl or one with a window in it. It would be the ultimate method of checking fuel level in the bowl. Not that it needs to be precise within a mm but for balancing carbs it would be nice to start with levels exactly the same both sides.

Unless you have brand new floats any other method of setting fuel level is inferred.

The hold the float parallel method depends on buoyancy of the floats - an unknown on old floats
 
The whip the bowl off and measure depth method is affected by residual fuel in the feed pipe. Anybody ever calculate the volume in the feed pipe and how much it effects the level in the bowl ?  Trust me it makes a big difference and the magnitude of error depends on which side you do first. I know you can pinch the feed pipe but only if it's fairly new and then it's still not a perfect result. 

Clear or translucent plastic float bowls would be the thing to have or if I ever come across an old spare bowl I'll cut a window in it.

A small packet of snake oil comes with the magic beans, uh, floats. You must lube the de-atomiser valve adjacent the high compression chamber before you will see the vast improvements proffered.

I have a small cage with some magnets in it in the fuel tank of one of my bikes - think its in the R65........  I think it was called a 'Black Cat' or something - been marketed under various names.  Worth extra bhp and mpg, apparently.   It came free with the bike -  Its still in there as I cant be bothered to fish it out.

Do the maths.
The om floats against the ethonol resistant. before they give out you are still looking at 20 years plus.why spend out a silly amount.
Depends on what you do with your machine to be true the r65 is well over 25 years old so why bother?

In Phoenix, we've had fuel with 10% ethanol for about 15 years now, I got the kit in anticipation of possible problems .

The additional bikes that I have acquired locally in the last few years, the owners stated that they have had problems with the floats absorbing fuel and then getting  'heavy' .

So it can be a problem just depends on the circumstances .

Agree completely! Even just one plastic float bowl to keep with the carb tools - use only when checking fuel level.

I had the same concerns as you about checking fuel level and came up with a solution you may be interested in.

You'll notice the bowls are cast to work on either side - so remove the blank-off for the choke pick-up tube. That way, this tool will work on either left or right carbs. The next step is to press the overflow tube out the bottom a ways and chop off the remaining inside.

Now you'll be able to attach some clear hose to the overflow exit - hold it up to the side of the carb and 'read' your level.

That's pretty clever! [smiley=thumbsup.gif]

Here's a similar method which involves sticking the tube down through the centre of the carb.

Your method is much simpler and better. Just needs a spare bowl. Alternatively I've often wondered if a hole could be tapped in the bottom of the bowl to accept a spigot. It could then be plugged for normal use. Hardly enough thickness of metal to do it though.

Here's another tip - Motobins has chrome 40mm float bowls (one side only) for 5 gbp. Check the close-out section. Next time you order, get one of those and modify it for your tool kit. Or take one of your pitted, almost ready to leak bowls, and replace it with a good new one. Use the marginal one for your fuel level measuring tool.

Also, the 40mm float bowls will work on both the 40s and 32s. The only difference is the depth. But the 32s won't work on the 40mm bings.

I've found that the correct level will place the fuel level about even with the front edge of the float bowl - remember, they're tilting forward. It's really difficult to get an exact level, but not so tough to get both sides close to the same height. I think that makes the most difference.
