Xplorer Misfiring and Backfires

Wot Cud It Be???????

[kirky]

you've got a right bike lol

this sometimes happenswhen it's sucking too much air, think base settin on my card is a 1 1/4 turns, dependin on your carb depends where the air screw is

might be other reasons but this is what first comes to mind, also check your jets are clear

Mine and a mates xplorer's did that once, gave air filter a good clean and it was sorted!

Make sure your exhaust is a good fit as this is what happens on my cr3. Had a flame bout 2 foot long at 1 point lol

Might be running ritch and if theres a build up of fuel in the exhaust then it gets a spark from the engine it will make a pop sound and maby a flame.

Or could be a tiny bit of water in the carb and its getting in the way of things so its not working wight. Minde did this a few times and all you do is spray WD40 into the carb.

Orrrrr Failing That..... Your Piston Rings Have Well An Truely Gone..:)

Running too rich. Blown piston rings would give it little or no compression.

I Think Its Pretty Normal For A 4-Popper To Back Fire.. Most If Not All Will If You Go Screaming Into A Corner And Let Right Off The Throttle.

[dan-mel]

yer every bike will do it, if you have it reving hard then back off the throttle.

It is just fuel in the exhaust building up then getting a spark or flame from then engine and poping and making a small flame out the exhaust. If you run your bike ritcher it will do it even more.
