  • Another Sportster is born!!!

    Yes it's true, I PASSED my SVA today!!!

    many thanks to everyone for their hints and tips with special thanks to John (from Warwick), Patrick, Stuart, Robin, Andy, Simon and Simon (at Marlin). Your well documeneted websites, posts, discussions,etc really helped me cover all the issues.

    I had a close shave on three issues. My speedo calibration was no good and was reading too low (a definate fail) but while we waited the 11 minutes for the exhaust gas analyser to warm up, Dave (the SVA examiner) let me do a two minute run at 60mph on his calibrated rollers which let me re-calibrate the Autometer speedo. It was then retested by Dave and it was absolutely spot on at all speeds! What a decent bloke for letting me do that!
    The next problem was a minor fuel leak from the top of the tank. Dave thought it was that I had over-filled the tank last night so 'gave me the benfit of the doubt'. I'll double check it anyway when I take the car apart for painting.
    The last point was that one of my rocker switches edge failed the radius spec. He suggested that I swapped two of the switches around so that he offending switch was in the exempt area near the steering wheel which I did there and then. He also recommended I put a heat shield around the brake pipes as they might get a bit warm.

    Otherwise, no issues, so I have my MAC !!!

          My oil pressure has never been that great, but whilst I was out this afternoon having a quick blast to test my spare wheel, the oil pressure suddenly dropped to practically to nothing and the oil pressure light came on burning bright!
          The light would go out above about 2000 rpm and the oil gauge was measuring about 5psi.
          Wasn't far from home, so got home, and got the manual out and started reading........
          There was no oil leaks and the engine oil level on the dip stick was normal.
          Then gave the engine a quick rev to see what pressure it got up to and suddenly it all came back to normal. It was like something was blocked and then cleared?
          I've decided to treat the engine to a new pump, oil filter and oil.

            Sounds like your oil pressure relief valve had stuck open. I'd strip it out and make sure nothing is jamming it or you could have an expensive rebuild.

              Thanks, Hugh. That's my theory as well. On the BMW m20 engine the relief valve is built into the pump. I've decided for peace of mind i'm changing the whole pump and valve for a new replacement. At £68 plus VAT I thought it was worth it rather than a complete re-build or engine swap. I should be fitting this weekend.

                I finished fitting my new oil pump and re-fiited the sump yesterday.
                New oil filter and oil and i'm now getting a healthy 25psi at idle and 50+psi at normal running speed.
