Starting to narrow this down ...
1.Got some exhaust tape and have a good seal on headers to mufflers again.
2. Installed fuel pressure gauge and I do appear to be right about 50 PSI plus or minus a few PSI. I do see that the analog gauge pressure needle vibrates around a couple PSI at a high frequency. I assume this is just vibrations and/or since it is flowing rather than a static pressure or should I be concerned?
3. Checked my Power Commander and it did not loose its map and seems to be ok.
4. Ran the engine for a little while, shut it off, and pulled the vacuum line on the fuel pressure regulator. No fuel flowed out of it or the nipple but the line did look a little moist. The nipple then slowly started to drip fuel. So regulator is bad, correct ...should never see any hint of fuel? If so, just change it and am good or is there other cleanup to do as I see it T's into other vacuum connections? Does it seem there was just a bad run of these regulators and once replaced are good for life in most cases or is it something that genrally fails every few years, etc? I have easy access to change it ... any tips to changing it or very easy? Thanks ...
Polaris RZR with an '04 SP2 transplanted in it. Chain driven through a gear box with axles and CVs. The only thing left stock on the RZR is the frame and plastics
. But, the frame is beef'd up too
