  • F80 Carburetor

    Looking for some advice. I have recently purchased a 2000 F80 (don't know if its the txry or tlry). Motor runs fine and everything I just would like to maximize performance. Upon and inspection of the spark plugs I noticed the engine is running fairly lean (plugs were chalky white). I have done some digging and was wondering what the difference was between the F100 and F80? Is it just Jetting differences? A lot of part manuals seem to list the same schematics with bigger jets in the F100.

      Any idea if the displacement of the F100 and F80 are the same? I can't seem to find it online anywhere.
