bub exhausts

Discussion in 'Technical and Troubleshooting Torque' started by bulldog, Nov 18, 2008.

  1. i have bub jug huggers on my xvs1100a yamaha. the problem is i cant seem to stop the thing backfiring on decelarating.i have removed the ais checked the plugs, vac hoses,exhaust gaskets all to no avail. do these exhausts just do this or should i be looking somewhere else to solve the prob.also the rejetting was done when pipes were fitted,its driving me nuts i paid alot of doush for these pipes. :roll:

  2. Easy fix. Remove exhaust, then refit with plenty of exhaust silicone. Stops all air leaks, which is your problem. Cheap fix too.

    Next time, do it right.
  3. I may be that the more open pipes just do that.

    Fix the air leeks as described above, then have a play with the idle mixture if it's still doing it.

    If that doesn't work, then live with it.

    p.s. Idle mixture is pretty easy to play with and start with 1/4 further out on each carb.
