Injectors cleaning

Now after 85 kilomiles 85k miles I am thinking about cleaning my injectors
by ultrasonic cleaners.Is it really nesessary? Has anyone have done it? Was the difference significant?

I assume that "85 kilometers" is a misprint. However I don't recall anyone posting that they've needed fuel injectors ultrasonic cleaned. Before you go to the aggravation and expense of ultrasconic cleaning why not try a fuel additive. I don't know whether this product is available in the EU but this is what is frequently used in the US to clean injectors.

I'm sure that something similiar is available in the EU.

What makes you think that the injectors need cleaning, anyway?

I do often use something similar by Liqui moly.And yes misprint.85 kilomiles is the correction

I think that they have SeaFoam over the pond.

+1 on Seafoam. Do BG products make it overseas? Those are also excellent.

Why waste time/money. Bike running fine leave it alone. I rode 2 purchased new SilverWings to near 50,000 miles each (80,000km) with no injector trouble. Just to make myself feel good on trips, every 1000 miles tried tank of Super Shell gas.

Techron is also good.  Cleans fuel sender, injectors and removes carbon from intake valves- pistons- combustion chamber.  1oz per gallon 12oz treats 3 tank fulls. Sorry already posted DUH

Marvel Mystery oil works, too.
