Motorcycle Fireing..

I have a Yamaha DT175 (N) from 2001. The engine shoots from the
exhaust and runs very roughly. Can someone tell me what could be
wrong?.

 

How long did it sit with gas in the carb? Or, how much dirt and water
did you get with your last gasoline purchase?
Either way, my guess is a fuel problem.

Oki.. well i guess that the gas is about a month old. in addition to
the above mentioned problems then its also seems like the when im
turning the throttle then the engine is about to stop.

 

I had a motorcycle act like this once. I pushed that pig for miles
getting it home. I drained a pint of water out of the gas tank the
next day, and all the rust and crap that came with the water really
caused a lot of trouble in the carbs. I hope your troubles go better.

 

This time surprisingly it had nothing to do with the carb. or fuel
system at all. I checked the spark plug and saw that it gave weak
sparks i checked the electrical system and cleaned some connectors for
corrosion. Checked the improved spark, screwed the plug on. Now it runs
fine!!
