Why is my bike backfiring??
« on: May 06, 2012, 01:45:24 PM »
So I just traded my yamaha ct170 for a suzuki ts185.

I also got a trike out of the deal, but anyways the guy didnt think the bike ran, took me fifteen minutes to clean the carbs and I was riding it up and down my dirt roads. 

Until i ran out of gas... Now i pushed the bike home got new gas and oil and tried starting it again. 

It keeps backfiring and a big bang comes from out the exhaust and air shoots out the carb.

The bike doesnt have a kickstand so it did fall over once, could that be why?

My neighbor recomended i get super gas, so i tried that and its still backfiring.

helppp

Also i dont have an air filter on it idk if that matters

Wild guess. It didn't run out of gas. The flywheel key sheered and now it is out of time (sparking at the wrong time). I would take a look there.

Timing, bad condensor, or try the easiest thing first...  put in a new spark plug. 

I don't understand how it happens, but I've had a bad spark plug cause a no start/backfire issue.
