Petrol Ain't What It Use To Be, Soul

I'm mucking about with a recent modern, 2000 TTR250, which has sat for about 8 years. You can see the 'petrol' has eaten away the nylon screen of the filter!!!

This is what I found in the fuel tap (haven't been into the carb yet). The muck is like half set contact glue, and just as sticky. I soaked it in turps, petrol and carby cleaner and barely softened it.

I'm going to throw it away and start again. OEM $60 in Oz / $35 in USA or $10 to $35 aftermarket. Much and all as I hate waste and giving in, too much time and the chances of not getting it all and causing a prob in the future are too high.

Heh, yeah, my missus put some of that ethanol shit into my 600 bandit, and than it sat for 2 months while I was away, came back and now I cant get it to start. Cleaned tank. Stripped and cleaned carbs, start ya barstard down the plug holes, nada. Gotta pick a compression tester up, I think the rings are gummed up. Pulled a mates mid 80's xt250 apart a few weeks back and the rings had gummed up and compressed the rings, no ring gap at all. Same deal as my bandit, let it sit for a while etc. cleaned the piston and rings up, put it all together and 3rd kick away we went.

Not really keen to pull the barrels off the bandit just yet..

Have seen E10 do some nasty stuff to the inside of fuel hoses.

I think it is the ethanol. I remember hearing/reading something about ethanol attacking neoprene and O rings over a period of time. The fuel ,system has to be ethanol tolerant even at 10%.
