    new 2 stroke, do I need to premix under the breakin period?

    Hi, I recently bought a 2008 gp1300r with 6.8hrs on it and by reading the manual it talks about premixing oil with the gas to help with the breakin period.

    I would assume it's probably broke in at 6.8hrs but since it's still under 10hrs if you guys think it's a good idea I will do it for piece of mind that it may help some with the break in process..

    thanks for any tips!

    some people add an ounce of oil per gallon just for insurance

    Does an ounce of oil per gallon all the time add extra insurance or does it do more harm than good?

    ...unlike the STXR, there have been no reports that the OEM oil/gas injection ratio is lean on OIL. Beyond that particular 2-stroke model issue, you're fine for summer temps adding a small amount of oil, but I would not recommend it in the cooler temps as you would be running lean GAS/air ratio as a result since you're effectively adding addtional oil to the mix/ratio and thus could cause premature piston wear/failure.

    It's different than what most people think. There are two issues that are at play:

    1. Oil and gas ratio mixture
    2. Fuel and air ratio mixture

    Less fuel, the hotter the engine runs/extreme amounts of oil the hotter the engine runs.

    (That of course is after break-in period expires.)
