Well i took off the pipe, air box, and throttle bodies to put on a new oiler cable. First thing i noticed was the oil cable loosed itself up and was over oiling for about half the winter last year. i check my plugs on a regular basis but didn't notice anything because when i got down to the intake boots i found both were ripped on the bottom side from my dumb self over tightening them. The good thing is i found both issues before i decided to ride this year which i was about to do. The bad thing is im building a mod IQR and now im down both sleds... Oh well its still early.
