Question about 2003 Honda CRF 230 F
I have a 2005 CRF that I bought used that had been siting in garage idle for quite some time. Long story short now that I have cleaned it up, drained all the old gas, cleaned the air filter, cleaned out the carborator with an air hose and put it all back together the engine back fires when I let off the throttle. The bike runs good when shifting up through the gears and I am throttling the gas, but as soon as I let off the engine pops with a back fire.
Is this something I can fix myself or should I take it to the dealer.
It may still have some water in the tank/system or the spark plug is no good.With a full tank of fuel,add 200ml of methilated spirits.It breaks up any moisture and lets it burn away.Also,with the motor out of gear,run the bike at higher revs and close the choke fully on and give full throttle at the same time.When the motor starts to die,flick the choke off.This can sometimes unclog a carby jet that may be slightly blocked because with the air choked,it gives a sudden **** off fuel.This may/maynot fix the bike but it the 1st thing to try before paying a dealer and it can't hurt anything.Hope this helps you
