oil blockoff kit on a 1200 non-pv
I have always done the oil block off kit with the removal of the oil pump on my waverunners.
yesterday, I went and helped a friend by his first Yamaha SUV but the oil was not blocked off yet.
before I convince him to pull out his wrenches and figure out how to be a garage mechanic I wanted to ask, is it necessary to go through the minimal work and minimal expense install this kit or can I just have him disconnect the oil sensing cable and jump it and simply switch to premix? I just cannot see any other necessary reason to do the block off. Also, if he ever decided that he wanted to abandon premixing it would be a much easier return to stock. Input please?
Forgot to add this: It is my understanding that oil pumps rarely fail. Given that, is their an oil line extension kit that someone sells to simply extend each of the 3 oil lines that feed the 3 carbs through the flame arrestor and then use a twisted wire vs. a zip tie to increase the odds of them staying on their respective connections? I'll be cleaning out the carbs anyway so that part would be easy to do a quick mod on. Again, the objective here is to give him a choice to easily switch back to post-mix if he ever wants to. I can't imagine that the small amount of air being sucked in through the 3 empty lines (if pre-mixing with the pump in place) would make any difference to the fuel/air mixture???

Go premix and never look back..............seen them done both ways......leaving the pump in with the lines blocked off and oil tank drained.......but I would suggest getting a block off plate kit......only $13 at azjetski in phoenix,az...........or shopsbt.com for $14.....if you get the block off plate you could always just switch back(but why would you?)...........

I would imagine that the pump might self lubricate using the oil from the reservoir. Not removing it and blocking it off may damage the pump. It obviously wouldn't matter a ton if it is never going to be used again.
Can anyone chime in if my assumption is correct?

I've seen too many issues with lines coming off. Mine did it at 23 hrs and I lost a cyl. A friend bought one and first time out had a line pop and lost the engine... not worth it in my book. Too much risk with affiliated $$$

Thats exactly what I'm wondering Chadbobb. I assume the pump is greased or a self lube job but when it freezes up...big whoop if a person is already on premix? Of course...that oil pump slides into the flywheel cover and the slot in it engages the flywheel bolt if I remember correctly? If it did burn up, I bet you could end up with metal shavings in the fly eh? Has to be a good reason for removing it and I bet that is the issue. $12 it is.

I just bought the kit for $15 shipped on ebay. Worth it without question. Its cheap insurance.
