I just bought an used Yamaha TTR-125 dirt bike.
Bike was running fine, all of a sudden it does not start using the electric start or the manual kick.
Battery is new and oil changed done recently also a new spark plug is put in. Please advise what cause the issue and how to resolve it.

Clean the plug and try again with the kick if the battery is dead,
if that works – you need to do some carb tuning, if not it
could be a wiring problem – make sure you are getting good spark to the plug

    I have a 2005 ttr125 and has been sitting all winter. I went to start it up and it would not start. The only way I could get it to start was by priming the carb with starting fluid. Once started anytime I added gas it would die. I took apart the carb and cleaned it. I still cant get it started without priming but it runs if I keep fuel running to it. It wont idle and it wont start back up after it dies. Not sure what to do.
