I have a 02 Yamaha yzf600r no start fuel is pumping, crank with starter fluid so theirs fire it's like gas is not going into carbs.


Jets might be clogged up or trash in carbs. Remove carbs and service them, then sync them again. This is common on any carborated bike that sits for an amount of time (like during winter), ethanol in modern fuel is also known to clog up carburetors.

On average, how many miles can I expect to get once the fuel light appears on my '02 yzf r-6


Once the fuel light comes on, i guess you have about 35 miles if you really ride slow. I suggest you start looking for a gas station as soon as the light comes on.

Backfires when reving down. high RPM then let off


lean out the system by adjusting the mixture screw. either less fuel or more air. also check to make sure your air filter is clean, that can also cause that problem.

Rough running 86 4runner after e85 put in!


very likely the fuel injectors are damaged, replace them, the fuel pressure regulator and all rubber fuel lines, also pull the gas tank and replace the short rubber hose at the electric fuel pump, I know this is expensive but even a few miles of running would have wrecked havoc on the rubber components, that rubber debris will flow through the fuel system and will plug the injector's, E85 melts it and skin for that matter.
