Oil Mix question

I just removed my oil tank and plugged up the hole in the carburetor and the two holes on the oil pump with vacuum cap hoses until I open my blaster up again to remove the gear and pump.

I have just bought Amsoil dominator oil and some people say to 32:1 with it is too much and will cause bad performance since it's racing oil and the formula is meant to be run at 50:1. They say to run it at 40:1 or 50:1 in a blaster but based on other posts, stock Yamaha blaster jets are not meant for 40:1 or 50:1 ratio.

What oil could I purchase and from where, to fix this issue and run it at the correct ratio, so my engine will last longer and have performance?

Thanks for your response, I forgot to update.

I wanted to try 32:1 since that's the most common ratio, so I went to my local motorcycle shop and they sold me Maxima Super M. I used the ratio cup and mixed one gallon of 93 octane at 32:1. I also changed my spark plug to a Br8es since that's what the shop recommended for it, the old plug had no marking on it.

When I went to start my blaster, I had to kick it like 10 times, normally it would start on the third with the previous owner's 32:1 Amsoil and the injector tank but would smoke a lot since it was way too rich and wrong formula. (I think he just bought it and didn't know anything about it and sold it.)
It also wouldn't idle and kept shutting off if the throttle wasn't held, and it would be hard to start again. When it ran, there was always a little smoke coming out of the exhaust, which I don't understand since Maxima Super M is said to be smokeless.

Did I foul a plug or put the wrong plug in?
(Sorry for writing so much, I just wanted to explain everything and thank you for your help!)

Thanks for your help, Awk08, I changed the plug and now it runs well. I wanted to ask you if it is normal for my blaster to smoke as much as it does, I attached a video. Maxima SuperM is said to be smokeless but my blaster still smokes a little after warmed up. I was only able to test it in first gear since I have a small parking lot.
