Hi Everyone, new to the forum,
I have question about the air compressor on my 2003 RX-DI. So I have recently purchased the ski blown up, did a while top end rebuild and the ski runs good. When riding I experience a sudden bog. Like running one one cylinder and if I let out and hit it will take off full power and run good WOT, then suddenly will fall on its face and if I let out and hit it again it may big a few times feathering the throttle and then have power again. I checked plugs for color and the PTO side was darker. I suspected it was a fuel issue, checked fuel pressure it was good with key on and also good when running. I also checked air compressor pressure and it was between 78-82psi, my Manual says 80psi for the compressor, so I’m assuming my gauge is not 100% accurate. I pulled the fuel rail off today and found a white milky oil substance coming out the air line into the fuel rail, the milky oil substance was also around the top of the air injector in the pto side only as that’s the closest to the air compressor line on the fuel rail. I’m assuming this is not normal and I need to rebuild the compressor which I have a rebuild kit for it. Just doesn’t make sense to me since the compressor puts out the correct air pressure. I’m just wondering if this has been anyone else’s experience with the DI’s. I will include a picture of the fuel rail where the air compressor line connects. Any suggestions would be appreciated.
