Carbon Cleaner
« on: April 19, 2012, 06:55:41 PM »
My St1100 has in the last few months started to make a slight ticking sound for about 10 seconds or so after a rev from idle then back to idle it ticks for a bit seems to be from valve area I spoke to my bike machanic he said wont be valve adjustment will be carbon sticky valve or valves and to put a bottle of fuel cleaner in and go ride it hard to clean the carbon out ........
Has anyone got a good cleaner to put in the tank they reccomend I will give it a go then see results

Hi Turtle,

Sounds interesting- I honestly couldn't say if he is right or not? Just not a noise I have ever chased down before.

As far as an in tank cleaner, nothing I am aware of cleans as well as PM800 (maybe Proma actually).  I've personally pulled off intake manifolds on injected and carby's off cars running PM800, after as few as 5 tanks- you can see the spray pattern from the injectors, down the runners to the valves- pristinely clean everywhere fuel touches, where the fuel doesn't reach you see the usual build up of carbon. 

$36 for 1 litre, which is enough to treat 1,000 litres.  By the end of the first tank throttle response will improve, I am still waiting for feedback from ST's but expect by the third tank to see consistant fuel economy improvements to the tune of 60km extra per tank (Based on what I have seen from other bikes)

Message me if you would like to give it a go

Brad

The valve gap on the ST11 usually close up rather than widen. The Techron cleaner seems to work ok when I have tried it.  I am going down the PM800 route for various reasons, some more to do with the car being converted to lpg

A little bit of diesel (maybe half litre per tank) works in cars I've had.  :bl11

Another PM800 trial coming up here as well. Both the ST and the 'cage' will get a dose soon.
I don't have any concerns with the current consumption in the ST but will be keen to see if it gets even better.
Watch this space.
Cheers,
