I just bought my 14 year old son a 2004 yamaha yz 125 and it won't spark. The guy I bought it from said he quit riding it in December and it ran fine. He said he cleaned out the gas tank and put new gas an oil mixture in it and he cant get it to spark. It will try to crank when you try to start it it just wont spark. He did the new plug on the motor thing and still no spark. Its a nice bike if I can get it to run, do you have any suggestions. Also the kill switch has been cut off and the wire is bare but down in the plastic cover. Also what is your opinion of this bike.
