    New gp1200 breaking in, questions.

    Hi, my Yamaha SUV is almost done rebuilding, should be ready to be in water by new week. I have a few question about the break in process.

    1) can I use the regular TC-W3 oil from Walmart? I am not a hardcore skier, I use my ski mainly for fishing and get to the fishing holes fast.

    2) I kind of want to use the oil pump as during fishing I will idle the jet ski offen and the amount of smoke premix is causing kill me ( I have a premix sl780 before). How do I test the oil pump and make sure it inject the correct amount of oil?

    3) One more idea is that, I can run the first tank 32:1 for break in, while I hook up the oil pump to inject the oil back to the oil tank. This is to make sure the oil pump is working fine, then after the break in. I can hook the oil line back to the carbs. Any one here done it before? Goes from premix back to oil pump?

    4) the service manual said to test the oil valve, connect a clean hose to it and blow. The valve should only allow the air to goes one way. Well I did that, and I tried and nearly blow my brain out. Just cant seem to blow air though either way. I end up using a compressor to complete the test. My question is that is a good oil valve easy to blow air though using only your mouth?

    I tested my oil pump by spinning it with a drill. I did my break in by mixing 50:1 in the tank and used my oil injection...so I had plenty of oil. You could do the same or use 32:1 premix. Just don't rev it up over 3/4 throttle because the premix ratio leans the air/fuel ratio down (less gas).
    I stayed under 5/8 throttle for about 1/2 a tank then started working my way up to short 3/4 throttle runs. Then the next tank was straight gas and oil injection and I was going WOT.

    Might be ok. I'd run it in a 2 stroke outboard boat. I wouldn't use it in a 2 stroke jetski. Jetski's are high strung performance engines and I prefer top quality oils. I use Amsoil.

    I thought amsoil is synthetic, and we are not suppose to break in using synthetic oil?

    Use a good 2 stroke castor oil for break in then run a full synthetic.

    Fuck sbt.

    Just go with the quicksilver.

    They make the best waterproof grease. It is called 2-4-c and is made by quicksilver.
