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.

Not allowed to.

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.
