    Ok, I have had my bike for two years and have run 91 octane from day one with the exception of once. I read in CP's newbies thread that 87 should be run. When I did use less than 91 (I think it was 89) my bike ran like crap. So my question is should I keep running 91? Or what would be the best thing?

    87
    90% of motorcycle forum members do not have a service manual for their bike.

      Read this thread, it has all your answers.

      Can't get it to run right? Find a trick to add HP?

        Thanks Ed... So you think I should run a can of Seafoam through it? I know the valves need adjusting, but anything other than that?

          Seafoam can help an engine. I highly recommend using it every 3-5000 mi... BUT it is no substitute for cleaning/tuning carbs and tuning valves.

          Give it a shot, good luck.

            OK thanks Ed, I will give it a shot. But like I said I know the valves need to be done too. How often should the carbs be cleaned?

              Manual says carb clean/sync and valve tune every 7500..... I think thats a bit pre-mature.... Id say every 9-10k OR when it starts running bad. whichever comes first. Obviously if you winterize it correctly and run it often it will need to be less frequently cleaned as opposed to someone who just leaves it outside for extended periods of time with no fuel stabilizer in.


              ...and no problem man, im here to help.
