Yep, great stuff. It's a wicked degreaser and the spray has a good bit of power behind it so gets the gunk out of the knooks and crannies no bother.

yes it is for cleaning out the internals of the carbs blow it through the jets and cleaning any crap out of the bottom of the float bowl it is air drying so evaporates quickly but dont get it near you eyes or mouth you will regret it

I get a bit worried when people use words like "going to town" and "give it a good scrub".

Carbs are intricate assemblies with jets that are precision parts.


The carb cleaner above is ideal. They are usually a strong solvent like acetone.

(brake cleaner is similar but a slightly different solvent). The inside of th ecarb often looks realtivly clean, th ecleaner will remove any sludge, varnish and water.


Take care with carbs. Clean the outside before dismantling them.

Try to remove the float bowl with e card the right way up - tricky but it prevents dirt form the float bowl falling into the jets.

Plus you will see how much dirt is in the float bowl.

Remove the jets and clean them with the cleaner. Check all the small holes are clear, look through them to a light (not too bright).

Don't be tempted to use wire to remove any blockages, use something plastic like a bristle form a brush, the jets are usually brass and easily damaged.

Check the float is not leaking, shake it to see if it has petrol inside. Check the float valve seat for excessive wear, if worn you will need to replace it,

Cleaning carbs is straight forward and as long as you take your time and keep track of what cane from where (pics may help) then it will be fine. Carb cleaner is designed for the job in hand and doesnt damage any seals and o rings.


Make a note of how many turns on jet screws ect

Just be aware that it will strip a lot of other things, paints, plastics, etc.


Take the carbs off the bike, completely away from the bike, disconnect drain hoses etc, then dismantle and clean.


I have a cheap oven tray for doing stuff like this in, collect all the black gunk that will run off.


The other way to use it is start the bike with the air filter removed, give it a squeeze of revs to open the throttle and squirt the cleaner straight in. the revs will drop but if you don't spray for long they'll recover.

My KLE500 is due a service. I have added the cleaner to the items purchased. I plan to start the engine and spray the cleaner in. How much should I use? It is a 500ml can. Is there anything else to know about?

It just says on the tin, spray in to carb from the airbox side while bike is going and it will clean carb. I removed the carb as I didn't belive that it would clean as good as stripping it down. Depends how dirty the carb is I suppose.

I have always been baffled why you spray carb cleaner in to the air intake!!


it will only pass the needle, slides and jets!


it wont go through the carbs where the fuel travels through!


the only way to clean carbs is to strip them down

:stupid:

How is it possible for this to work effectively with the engine running? It will be sucked into the engine and fired out before it even had chance to touch the sides, a strip got to be the only way

It can't be as effective, I wonder if it's just one of those lazy / less scary to the uninitiated options they put on the instructions.


I wonder if it would have a small effect cleaning the back on the intake valve and maaaaybe piston crown. Not so bigger issue now but back in the day when you stripped down your A series to polish the ports, a squirt of carb cleaner in the bell mouth was a lot easier.
