I'm getting ready to assemble my Blaster engine and would like to know the best premix ratio for engine break in. I normally run 32 to 1 in my other two strokes. However, on break in it may need a richer mixture. Any advice would be appreciated!

 

Run the same mix that you run regularly i just did my blaster top end and am running 32:1 which is a little rich but its what i always run

 

Don't use a diff ratio for break in.

Grab the oil bottle of your choice, and see what the manufacturer recomends for that particular formulation. Stick to that ratio and you'll be fine.
Keep in mind that if you change oils/ratios that rejetting may be necessary.
