    Thats not the case at all. A lot of guys used yamalube with no issues premixing. I use klotz R50 myself for years, its a oil specific for fuel injected motors. Others you amsoil interceptor I believe. Who ever told you that doesn't know what they are talking about! we have been mixing 1300 fuel injected motors since they came out in 2003!

    Also You have one of the best tuners/mechanics in the country right by you in Tarpon Springs. Jims Performance do a search he is all over the forum! Great guy I drive from NY just so he can mod my skies!

    Hello sebasGP1300, yes you can pre mix ... but why would you want to ? If your GP1300 is working fine no need. You will be hard press to find anyone who can honestly state that his oil injection system failed on a GP1300. There were problems with GP1200's in the past where the oil lines would shrink & tighten up & thus pull off. But on the GP1300's this is not founded. It is simply a precausionary procedure from the past. When I inspect the oil lines on my GP1300, they are fine and no short Cummings (pun intended). Like I said never found one case where the oil injection system failed. Good Luck

    Thank you guys for the response. And I would just rather premix just to be able to have that ease of mind.my biggest concern was the injector fucking up like they told me but if you guys said that wouldn't be the problem then I would just rather mix and not be worried about it.

    Well I am sure you want to error on the safe side .... however, do realize that in order to go pre mix you will have to remove your U-Shape exhaust chamber section to get to the front of the engine where the flywheel housing is. Then you have to pull off a perfectly good oil inject pump section & install a block-off plate. Then you will have to remove the other portion of the exhaust system that sits over the fuel rail/injector system to cap off the oil lines. Again, go back and check with those who have recommended you remove your oil injection system from your GP1300R. I really think you will be very hard pressed to find one person who can testify that they had a GP1300R oil injection system failure. So removing a perfectly good operating oil injection system is not necessary. But good luck .... and let us know how you make out.

    Not to mention, you will use a ton more oil going premix. Then you have the hassle of premixing, fueling out on the water becomes a big pain. Sounds like a solution in search of a problem in this instance. To each his own, but premix does not necessarily mean more reliability. reliability comes from what you do to make it reliable. Plenty of stories of friends thinking they would be nice, gas up the ski, and not realize oil had to be mixed in.

    very true ,its a big hassle .mine was premix do to increase comp , and tons of aftermarket parts, if it wasn't for that the oil system will still be intact.
