If you want to use supermarket fuel you might want to consider the idea of adding 300mls of 2 stroke oil with a tankful of fuel.

There are folk who won't agree but the thread on here will give you the gist of the arguments. I do use it and my MOT smoke levels were hugely reduced after 10 months of use. It isn't the same as the fuel additives used by BP, Shell etc but I and many others are convinced it goes a long way towards it at a lower cost.

Possibly happened again tonight, but maybe it was me trying to accelerate in 3rd at the wrong time.... A bit of hesitation and kagarooing. Will try not to think about it

Still doing it now and again. nearly 1 year service time so will ask them to have a look ( and check out the clutch) since I'm sure it doesn't drive like it used to !
