Where are you ??? Dodgy fuel how ??

Well the first thing you should do is drain the carbs, drain the tank and fill it up with good clean fuel..

You have to be more specific with "dodgy fuel".. was in low octane, watered down or just made from sea water ????????????

Silicon in fuel is a new one to me...

If carbs and tank are cleaned out and its still running like crap, maybe you have to clean out the injectors (FI???), fuel rail and then change the plugs.

It doesnt make sense that they would use silicon to clean lines unless it was silicon abbrasive.....

You would probably have to clean and inspect everywhere where the fuel would have contact with.

If he filled up in the UK with that, then he should probably be writing to the garaage and his solicitor.

Silicon in fuel was back in March 2007. BBC NEWS | UK | Firms curb supplies in fuel scare

I have read reports that it can cause damage to sensors, especially the oxygen sensor so I would check this first if the bike has one.
