Anyone know what the Ratio is that the Oil Injection is feeding these things and has anyone figured out how to adjust them?

Not sure but I thought I read it is in the area of 32:1 or 36:1

If it is 50:1 that'd be super but I was thinking it to be somewhere in the 30's too. There has to be a way to adjust it I'd think though.

Just a suggestion, but why not block off the oil injection and mix the fuel yourself? That would give you control over the mixture and you wouldn't risk a failed oil pump.

How about the good ole' Daisy BB. LOL. I believe the only way you would be able to adjust the ratio would be to change the little gears to a different ratio. Good luck with that!

Yeah the Ball bearing / BB trick is great for killing it completely also illegal I believe for the Limited Class's. Guess we are stuck running richer than heck :(

our polaris minis have an adjustible cable for the oil injection. It seemed like it added oil when I backed out the adjustment to leangthen the cable, seemed to smoke more at WOT. The adjuster was about 6 inches out from where it hooks to the oil pump. I'm not sure if the DRR's have that?

The DRR has this adjustable cable too but from the little i play'd with it it appeared to already be adjusted to its longest setting, I just figured that was their way of keeping the end user from leaning it too far out.
