Hi everyone, I got a new cbr250 in 2013. Drive it for 278 miles and then life got in the way and now have a beautiful mess on my hands. Bike won’t start. When I turn the key it cycles through with the correct clicks but the fuel bars flash and although it turns over it doesn’t start. I tried all the tips here: replaced battery, drained and filled tank with additives, tried starting many, many times with different throttles combinations, cycled through startup many times all to no avail. I ended up pulling the tank off and what a mess. The gas has turned to a foul smelling rust-like substance that coated tank. I’m guessing it turned to varnish. I have been cleaning tank and tank components over the past few days and this gunk is dissolving slowly but surely. My question is, now what? Reassemble and try again? I’d like to test what I can first. Is this varnish in the injectors? Thanks in advance for any tips!
