Two questions (not related):

1) I have some backfiring (small sound but loud enough to be heared with my helmet on) when decelarating in cold weather. Does anyone of you had the same problem ? What should I do do stop that ?

2) How often do you check your oil level ? Do you add oil often ?

Thanks

A couple of threads on backfiring you might want to read:

Depending on how much I'm riding, I check my oil every couple of weeks. I've not had to add any ... yet.

Petyot, many of the 400's ......not exactly a backfire, more like loud fa.ts (expelling gas). Mine does an outstanding job at this as my engine/muffler is louder than my buddie's 400's. Milage does nothing to cure it.

Popping on decel is usually caused by a lean condition. Does anyone know if the Burgers have a pilot screw that can be adjusted to richen it up?



Peace.

POP!

I've seen a couple of scews near the injector but have not seen any
information in the service manual that explain turning them.

Try setting the idle to the high side in order to get the engine richer
at idle. Do this adjustment when at operating temperature. Don't
burn your hands. Remove the two screws for the plastic cover before
you remove it. These screws like to fall into the lower body otherwise.
Your owners manual tells how.

The service book does explain that there are sensors that tell the computer
information about pressure altitude and temperature for automatic
adjustments.

There's marked improvement by simply filling with 87 octane fuel.
My 400 starts smoother with the cheapest gas I can buy. The most
expensive/high octane gas will give faster throttle response though.

Too much backfiring can mean that the valves are in need of adjustment too.
