I’m only just catching up with this thing. Thanks to an article in this weeks MCN I discover that an increase in the percentage of ethanol in petrol is on the cards in the UK and maybe Ireland as well.
The main bike manufacturers have stated what models will work with it and so far I haven’t seen a model younger than early 90’s. I also know that some tank sealants like petseal have had problems with ethanol content before this, and now some manufacturers are saying their own production sealants will fail with a 10% ethanol content.
I have yet to find specific info for my situation but I would suggest it’s worth watching out for the E10 badge when your filling up your old bikes tank.
