Yes, actually you are correct. Maybe you do know something. It's the exact same casting as the Enticer 250. I have a top end from an Enticer sitting on my workbench as we speak, waiting for hone and install. And you are right, as I said already, that these are low rpm engines and less oil is ok provided that you are not dropping the hammer constantly. The Enticer, however, with the port size and configuration will want to operate at a higher rpm, prob 2k higher than G1. More power, up to double as well.

[/QUOTE]the g1 if governed to stock settings would be ok with a your mixture of 2oz/gallon, but if you have your screw turned in and blast around WOT its advisable to go with at least the 50:1 mixture.[/QUOTE]

If you are running "balls out" then you definitely want more oil, so I agree with you again. Yeah 50:1 will prob smoke, but if that's not a concern at all then by all means pour it in.

You see Jeff, we are saying the same things. That's great. You sound like you've worked on 2 strokes for a while. What I wasn't appreciative of was you pointing out little things making me look like I didn't know what I was talking about, and that you say I "need to use more oil". I've done the research and I know this particular engine very well and I am making an educated decision. I never told anyone "what they should do", that's silly to be that way. I shared my experience and trust that the "OP" will make an educated decision as well.

at 50:1 you can drive it however you want and know that it will have proper oil content to lubricate the complete engine internals but not to much oil that you would risk running the engine to lean.

Enjoy!

FYI...thanks to Smallblock450sl, in the Yamaha service manual in the "specs" section it says...

"Mixing ratio 150:1 at Max. power"

This is obviously with the factory oil injection system. I would imagine that the oil is mixed variably with rpm.

So, 65:1 would be more than double the oil content of the factory injection system at full throttle/max power. As far as protection goes you are fine. It will likely smoke. But do whatever you feel comfortable with.

Don at plowmans carts told me himself i could run a lot less oil and be ok if i was just riding it as a stock cart but if I planned to bypass the gov., which I do, then he would run like 60:1 ratio with a real high quality synthetic oil. He suggested using Amsoil

Don's a good guy, he knows his stuff. Literally a 2 stroke expert.

50:1 here amsoil dominator.

Why take a chance !
