In order to meet epa gas mileage requirements manufacturers have bikes running lean & hot. Also there is a valve that feeds some fuel back into the exhaust. Hence your bike backfires on deceleration and sometimes when starting and who knows when else. Without going into a political rant, here's what you can do.
There are kits you can purchase to disable the valve, combined with the addition of a fuel injection controller to richen the fuel air mixture - backfiring will disappear like magic. Check into it.
The best answer for this is: Get a tune-up.
If it is backfiring the timing is set incorrectly or the spark plug wires are not connected in the correct order.
Rev the engine six or seven times before coming to a complete stop. Rev it all the way to the edge every time you stop.
well if its a 2 stroke it needs new reeds if not, your timing is prolly off a bit
More than likely you have a exhaust leak.Check the headpipe seal
Backfiring it normally caused by a car that is very badly out of time. It can also be caused by the spark plug wires being connected incorrectly. Switching to a higher octane will not help at all.
NO, but a good tuneup will probably cure your problems. There is no cure in a can for the symptoms you list.
Backfiring is caused by incorrect timing, or plug wires installed incorrectly which messes up the firing order. Make sure your plug wires are installed correctly. Can also be caused by an overly rich fuel air mixture.
Cost too much $
if it only backfires when shutting off, usually this means its getting to much gas!! if it backfires will running adjust carburater.
They stopped making the LTR 450 becuase the EPA has come to the conclusion that the LTR does not meet their emissions standards although they know that Suzuki is on top of its game when it comes to quads. But unfortunatly they have forced Suzuki to stop selling this machine.
she is so funny
