Bmw K1100lt
Guys, or Galls, I have a problem with my K1100LT. Last weekend was a great weekend away at the MotoGP in Germany until the journey home. The bike is fine around the 80mph mark but on deceleration to lower speeds starts to cut out and 'pop'. When it is revved again it picks up and pulls up to 80 or so and is fine again, Fuel, air filters were changed recently and the plugs have been in for about 2000 miles. Any ideas would be greatly appreciated. Shooey

This is totally non-bike-specific, but it sounds like you are getting a lean condition on deceleration.
A lot of bikes will pop when 'engine braking,' especially from higher rpms, but yours sounds excessive. Two causes I can think of: manifold leak, or something wrong in the ECU/Fuel map.

I'm with pushrod on the fuel mixture. Those symptoms are common when guys open the exhaust but don't adjust the intake side accordingly. Did you make any changes to the suck, squeeze, bang, or blow lately?

Many thanks for the info guys, from what you say it may have just been some 'dodgy' fuel at the last tank stop. I'll give everything a good clean at the weekend and put some new plugs in, check the timing etc and let you know the results. Thanks again.

shooberj,
Ken makes a good point. Have you modified the exhaust system in any way? Incorrectly reducing the 'backpressure' characteristics can cause all sorts of weird effects. One of them is increased popping on decel.
