Just moved from Sunny and warm Phoenix AZ (1,000ft elevation) to cold North Dakota (2,000ft elevation). Bike runs flawless, throttle is nice and crisp all the way through, even blipping it from idle with no bog. However, it's running too rich, spitting oil out from the header and pipe. What do I need to do to correct this? Bike has FMF sst pipe, shorty silencer, and VForce reeds.
