Ultrasonic Cleaning Service

The power of ultrasonics for cleaning parts without invasive procedures or using toxic and environmentally unfriendly chemicals has been known for many years. I was fascinated by the way dirt was just floated off components in the big ultrasonic tanks in the factory where I served my time as an engineering apprentice,

The basic principle is the use of ultrasound to create millions of microscopic bubbles in the cleaning fluid, which implode with relatively huge force as they contact the substrate. This action loosens the dirt and grease and will even remove stains. Most cleaning can be done using plain water with maybe a dash of dish washer detergent to help; some materials need a specific cleaner fluid to disperse them.

Most parts can be cleaned in this way;

Carburettor cleaning: 
The carburettors are probably the main cause of running problems on the four cylinder Wings and it's my guess that 90% of those endlessly ongoing problems are down to the fact of the very tiny passageways and jets in the Keihin Carbs not getting properly cleaned. This is no reflection on the poor owners who have had them on and off and cleaned them more times than they can count.

Brake Master Cylinders: 
How many posts have you seen on the forums saying that they can't get the brakes either to make pressure, or to loose the pressure that is in the system. Many, many times this is due to the very small ports being gummed up. Ultrasonics will get all the gums and corrosion out and keep you from tearing your hair out by the roots, or from giving up and throwing the offending part in the nearest waste bin.

Brake Calipers: 
The piston sticking in the caliper is most often caused by corrosion behind the seal in the caliper. This can be cleaned manually but it's awkward to get all of it out. The ultrasonic bath will remove every bit and leave your parts like new.

Cylinder Heads: 
Sometimes the passages in the water jacket can get furred up, and if the oil changes haven't been frequent the head can get very gooey with old burnt oil. Send us your head and a few lazy minutes lounging about in our ultrasonic spa will make a new man of him!

How we can help; (The rebuild services noted below will come on line in due course.)

Carburettors:

Here we are talking simply about cleaning. Your carbs need to be removed from the plenum chamber for cleaning to be totally effective.
This you can do yourself or we can strip the rack for you, meaning that all your components get cleaned at the same time.
On return, all internal parts will be individually bagged and labelled per carb; the float chamber, the top and slide remounted but no further rebuilding done. You will need rebuild kits for each carb plus a plenum gasket, or Randakk's master rebuild kit which we can supply.

Price including return shipping UK: per carb £20.00
 
Add £20 for us to strip the rack, clean the components and return with the carbs.

Brake Callipers and Brake Master Cylinders: 

Here we are talking simply about cleaning. Logic says that if you have any one of the three front cylinders removed, or either of the back cylinders off, the bike is not going anywhere! So you might as well get all three fronts, or both rear, or all five done, at the same time!
No remedial work done on any of them. You will need new seal kits for each cylinder.

Price including return shipping UK: £10 / unit, £25 / front three, £18/ rear pair. These prices assume no problems. If we run up against severly jammed pistons or immovable bleed screws for instance, there will be additional charges. They will be advised to you before we continue with the work.

Cylinder Heads: 

Asssembled heads do not have to be stripped of valves and springs, but we can do this if required. We would advise that the cam carrier, camshaft and rockers should be removed. They are rarely dirty enough to warrant ultrasonic cleaning and they add a considerable weight to the head.
The valve seals will not be damaged by the ultrasonics but if you have things stripped down this far you would be very remiss not to renew them as a matter of course.

Price including return shipping UK:  £18 / head
