1998 gp800 premix ratio

[stanleydan]

Hi Guys

just finished my gp800 rebuild. I choose to remove the oil injection and go with premix. What would be the ideal mixing ratio? And can I use the same yamalube but premix it?

Thanks

50:1 be fine but since its a new rebuild do 40:1 for the first two tanks. yamalube is fine.

Make sure you breakin the engine the right way.

Breaking it in? There's nothing wrong with 32 or 38 to 1. It will smoke, but the bearings get some love. Test after test have shown that more oil, to a point , doesn't effect power. Granted that's with a good oil.

break in the fresh build engine, run the jet ski at 1/4 Throttle then rest 1/2 Throttle then rest 3/4 Throttle then rest and then WOT........
actually more oil mean less gas, the engine will burn hotter (lean).
