What would cause oil to get in the air filter? Also, what would cause the front tire to wear unevenly.
Uneven tire wear is caused by running with the tire pressure too low. Often 35 PSI will keep the tire wear more even. If you ride a long distance with a strong cross wind you may notice wear on the windward side of the tire (just off center). This is because after riding in the crosswind for a long period of time you have been leaning into the wind and are wearing the tire off center.
Oil on the air filter typically is coming from the crankcase breather. Check your oil, it is probably contaminated with gas from your tank and the oil needs to be changed as well as your air filter.
you have a vacuum style fuel petcock , the vacuum diaphragm has a hole
in it. The gas leaks past the diaphragm, down the vacuum line, into the
intake manifold, into the cylinder, past the piston rings, and into the
crankcase where it mixes with your oil.
If you have a standard
on / off style petcock, all you have to do is leave your fuel on and
have a float needle stick in one of you carburetors. The result is the
same , the crankcase fills with all your expensive gas from the fuel
tank. This can happen to any motorcycle that is in perfect order.
If the four hole washer in any style petcock gets worn (thin or torn) ,
that can be the cause of a fuel spill into the engine. Always turn your fuel petcock off when not riding.
with a thorough inspection of your fuel petcock for bad rubber parts.
Replace any bad parts with new. K&L makes after market fuel petcock
repair kits if you just want to rebuild . If money is no object a brand
spanking new fuelcock will work for sure. If running a quality fuel
system cleaner like "Chevron Techron" does not stop the carburetor float
needles from sticking, your may have to disassemble the carburetors and
clean them properly and replacing the float needles during the process.
