I'm going to be pulling out a bike of mine (gilera nordwest) that has sat for years for resto later in the year. They were always a bit of a mare with fuel being left in the carb for more than a day or so, so a full carb strip will be one of the first jobs. I've had a look and a 2.5litre ultrasonic cleaner unit is only about £50. Anyone got any experience with them?? I'm thinking it may be a handy thing to have around for various cleaning jobs if they work well enough.

It's been found that a lot of these Chinese unltrasonic cleaners are little more than a pot with a small electric motor underneath that spins an off balance weight that makes it vibrate a little.
You'd probably find a paper mache umbrella more useful

Might do a bit more digging then. Did watch a youtube clip where a fella attached a pot to a sander, suspended it with a cleaning agent for an hour or so. Got fair results to be honest, better than i would have thought it would achieve.

I cleaned my SUs using an old tooshbrush and some neat surfex HD. Worked a treat.

I bought a cheap one at a local shop. Wasted money in my opinion.

I've used a bowl of cola to soak carbs in before when rebuilding them.
15 minutes in the bowl, rinse it out and then carb cleaner through the jets and ports. Vinegar works too.

I've used vinegar to good effect,balsamic seemed to work best for some reason. I have an Ultrasonic for cleaning watch and clock parts,it was about £100 from Allandale electronics.Stainless cased with a heater and a decently powerful transducer.It works a treat but it's only about 1.5 litre capacity so limited in terms of getting car parts in there.Stripped carb components would go in though.
Agree completely about the cheap ones,waste of time they just have a motor and a balance weight agititor not a proper transducer.

As above, the cheap ones are a waste of money.... Been there and found out to my cost
I too bought an Allendale stainless tank around 27 litre capacity. It's big enough to get a full bank of 4 bike carbs in without having to split them. Wasn't chesp but certainly does what it's supposed to

If it can be fixed with a hammer, then it must be an electrical fault

My good one was made in China,so not slating Chinese made stuff in general.I have used ultra cheap ones and they were junk for the reasons mentioned before.The problem i have with some of the Ebay/Amazon ones is that it's hard to find the actual spec of them so you don't know how powerful the transducer is or what the duty cycle is.Some are probably ok but it's a gamble. The bigger the tank the more power you need for effective cleaning too and what you use as a cleaning solution makes a big difference to performance as well.Whatever you use it needs a wetting agent to aid contact between the solution and the item to be cleaned. I tend to clean things in jars filled with cleaning solution and then have those immersed in a hot water bath in the tank.Thats saves a lot of waste with the cleaning solution and saves the need for a heater.The cavitation bubbles will pass through a glass jar no problem.You find the cleaning solution heats up and gets warm as the machines is in use anyway.
