    C1/R1 Users - have you verified AFR's?

    Has anyone runnin a C1 and R1 combo checked AFR's without a powershot? Just wondering if it's been verified.

    It's spot on. I have not tested it myself, but you can call R&D and they will tell you the R1 is perfect for the C1 wheel with no powershot. They've tested it extensively. You could even throw in a set of cam gears and A/F will still be extremely safe.

    I would get the R3 tune if you want to run the E1. And, if you tell R&D on your order, in the comments section, that you want to be able to run an E1 without the powershot, they will use a fuel curve that will get you there. However, you can't go leaner using a powershot, so if you are are a little on the rich side, you're kinda stuck with it. The other option you have is to just get the regular R3, and use the powershot to dial it in. It does work that way too. Just mount the powershot in a nice safe dry place and you shouldn't have any issues.

    We will soon find out about the C1 and R2 and AFR. I've "heard", the AFR should be fine as well.

    Does it need more fuel for this setup? I plan to run the B1 and R2. Dont know about the difference between the R1 and the R2, but the R2 with stock wheel is very rich throughout the rpm range.....

    Ask R&D to tune the R2 for the B1 without the Powershot(or maybe add the RRFRR). I believe that can do that.
