DNF

Hello Alan, Thats a very good suggestion and one I shall look at. Thanks for taking the time to respond.

hello, feetupfun, thanks for the reply, I have looked back through and found previous posts regarding the deteriation of plastic parts in contact with modern fuel. I have now learnt what the symbol E10 means when I draw fuel from a filling station and suspect that the 10 percent Ethanol content in unleaded fuel is the cause of the damage. In future I shall go for a super unleaded 97 to 99 grade. Seeing the damage to the tank and through the resource of trials central and the forums has opened my eyes to a subject largely unreported in the UK. In future I think it wise to drain the system down between use. I still have to address the issue of the rear tyre runing against a bolt. I am uncertain as to the width of the origonal tyres as fitted by scorpa, Thanks again for your response

New to trials. Bought a SY 250. The bike has been in storage through out 2019. the fuel tank now shows signs of external blistering. I suspect the fuel has reacted with what looks like a GRP tank. Is this an inherint Design flaw, should I have drained the fuel between use, Will the fuel eventually work its way through the tank, any risk of contaminated fuel will degrade the carb. Is there a cost effective repaire or a means of linning the tank or is the option to source a breakers replacement. There is also the issue of the tyre wall on the rear wheel is rubbing over the head of a bolt that secures the chain guard. The bearings feel sound, not sure if the issue is the width of the Michelin tyre. Any advice appreciated Thanks
