Has anyone ever seen gasoline gel?
I pulled the carburetor off of a KTM 400 last night (see below for details on THAT little feat...) because it had been starving for fuel. Inside the float bowl there was plenty of gas, but there was a gel-like substance in the float bowl. Not a lot of it, but enough that it looks like it would have messed with fuel flow to the main jet.
It felt kind of like grease, and that's what me and Mechdziner thaought it was at first. After hitting air and drying out, it looked a lot like the crud you find in a carb or gas tank if all the gas dries out.
I've never heard of pump gas doing that before. I know some of the exotic racing fuels will do funky things if left in a gas tank/ carb for a while. I dunno. Maybe the prefious owner used one of the racing fuels?
OK, disassembly story:
After removing the seat and gas tank, I was naive enought to think that the clamps would be loosened on the boots on either side of the carb and just pull it out. Nope. Not that easy...
Fine. Let's pull off the side panels. Aha!!! Right there is a big, uh, airbox.
Fine, let's pull the airbox. 6 or 8 bolts later and no dice. The airbox is going nowhere with the rear subframe in place.
Fine. Remove the exhaust can, no biggie, just cut all of the safety wire I put on the springs in case Stephen ever rides it again ( ). No problem, anothr 6 or 8 bolts later and...
Holy crap! It looks like (and I'll verify when I reassemble it in the next couple of days) I could have loosened one clamp on the air box boot, removed two bolts off of the top of the subframe and just pulled it back like a hinge. Airbox, subframe and all just pivoted back as pretty as can be. Pretty slick...
