Question about 2003 Yamaha YZ 125
I have just got a 2007 yz125, and it has been taking alot of kicking to get it to start. But when i finally get it to start and warm it up, it dies when i take the choke off. It sounds like its not getting any fuel.
Starting with the basics.Turn off the fuel.Remove the plug from the bottom of the carby float bowl.(17mm I think)Catch the fuel if you can in a glass to check for dirt and or water.Turn on the fuel tap and let some fuel run through and out the bottom af the carb.Turn the fuel back off.Replace the plug and turn the fuel back on.Sometimes just some **** in the floatbowl can cause problems.Start the bike and warm it up.In neutral give the bike full throttle and at the same time,flick the choke fully on and fully off a few times.The sudden on and off 'sucking'through the carby MAY dislodge a small piece of debris in a jet.Next.Check for water in the fuel.Do these steps before you pull stuff apart.It only takes about 10 mins.If these dont work its a good chance the carb has a bit more dirt in it that needs to be cleaned out.This is a guide as a starting point.Hope this helps
