    WOT smoke trails

    i blew bast my buddy today in 3rd gear wot...shifted at 9k 3rd an 4th....he said it was smoking...not bad but noticeable...but only under that high rpm or when i let out..cruising it wont smoke at all...rarely it will smoke at start up...but i figured cold morning was causing that...

    smoke was white/blue..or grey..i was told i didnt see it

    so uh...does it need head work?..no clue if the bike has ever had any..or is it normal...

    81 850, 4-1 header- 120 main jets (rest stock)

      Hi babes. If you suspect piston rings then a compression test is the best way to check...
      Check normally, then squirt a small amount ov oil into the pot and try again...
      If the readings are really different, its ya oil rings.
      Hope that helps some.

          Either your running rich on the main jet or there is some oil getting past the rings. Compression may be fine and the oil rings can seep.
          Can you live with it? Are your plugs fouling?

            Its most likely just carbon/soot buildup in the exhaust pipes.
            Happens when you get it way up in the RPMs, and the blow the crap out.
            If your friend is following you, he should be able to tell you if it smells like oil, or soot, or Rich Combustion.
            Note: Rich Combustion can be scented from behind with a mild Throttle Up.

              I put a pipe on a bike that had been on a blown motor.

                Was that the one from the cooked 1170?

                  Yup
                  When I put the yellow banana motor in my L. The motor I had Aluminum weeping through the valves from the pistons.
                  I ran the motor with a rigged ignition and just a sidewinder header so I knew it didn't smoke but it did with that Kerker pipe! BIG TIME!

                    Like stated earlier it is probably just that the main jets are too large and it is running too rich at WOT.

                        Take the vent hose off and see if there is a lot of oil residue in it. If not then you should be fine.
