Back fire?

[machine]

04' KX5 back fires sometinmes when trying to start???
It did it before I had a new flywheel, and stater put in it.
And it still dose it after???

Mine does it sometimes on the first kick when it's cold.  I try not to give it to much gas when I start it and seems to go away.

I'll give it a try!!!

See me, I would be worried bout that, not had a backfire from mine yet

[machine]

Well, it does worry me.
I just got it back from thr dealer, and they just put in a new
stater, and flywheel.
So I would think that they would have timed it right?
What else could it be?

BTY; It's only done it once since I got it back from the dealer???

Hummmm?

Mine backfires on startup sometimes as well, my guess is like you figure it could be timing related.

Mine backs fire sometimes but only after choking it for a cold start. After it back fires the next kick it pops off and it's a live and ready. Mine has never back fired during hot starts.

I get the same results.

Same when cold at times.

I think most all of the 2 strokes that I have owned over the years all back fired when they were cold and started on the next kick!

I'm with Alan. You guys should try starting my PVL KX500.. :-/ Talk about kick-back and backfires. It will wake up the dead.
