Converting 800 ves to premix

[Twostroke]

I'm going to convert my 800ves to premix. I know where the passage is I need to drill out but..

What size drill bit should I use?

Is running a small oil bottle that by passes the oil pump but goes straight to the cases/stock oil injection locations over-kill?

I want to make the motor as reliable as possible as I will be running a big bore off the stock bottom end. Clutch is getting balanced, extra motor mount..

if your uncomfortable doing it yourself you can send it to SLP and they will do it for you.
If you are wanting to get after it get a 1/4 inch bit and drill it anangle so it will make sure to open up between the bearings. If you go straight down it hits the bearing race and doesn't do any good. You have to angle the the hole outward.

Block off the stock injection holes and mix it up and run it.

I'm not scared, ever. Thanks for the info.
