    Leave / Remove Oil Injection on 2001 SUV?

    I recently acquired a 2001 SUV with a frozen crank. I found a local that was selling a 1999 GP1200 motor, so I bought it complete and swapped it in (I'll fix the other motor later). My question is; should I trust Yamaha's design or simply switch it to premix? I've learned to trust Yamaha's engineering, but I run all of my other skis with premix. Are the 1200 motors reliable when it comes to oil injection?

    Thanks for any help. I appreciate it.

    Jake, I have had two GPR's and a XLT. The 1 GPR had a clogged or gummed up oil line and seized up. The XLT also seized up. From that day on one of the first things I do is Block off and premix. I really never heard of a oil injector pump stop working. I have heard of clogged or broken oil injection lines. Also I would highly recommend getting carbs rebuilt I learned that the hard way. Hope this helps with your decision. Frank

    PS I would contact Osidebill with all Carb ?'s

    Thanks so much for the honest answer. My gut tells me to go premix, so there's no worries about lubrication, but Yamaha engineers are some of the smartest out there. I think I'll do it now. I'll also talk to OsideBill about the carbs. Thanks again.
