This subject prompts me to raise the question of the adverse effects of ethanol in modern petrol which I understand creates some serious problems and attacks the inside of fuel tanks, especially plastic and fibreglass ones. I believe the current ethanol content in todays petrol is about 5% but is due to increase considerably in the coming years.
I also believe this is why old bikes often won't start with old stale fuel still in their tanks that's probably been there for years, and has clogged up venturi passages in the carburettors.
Before I ramble on and risk posting incorrect information I'm sure there's someone out there who can elaborate on this subject with much more definitive info. than I can, so I suggest it's a topic worth discussing if the moderators think its appropriate.
I rest my case!
