2004 drz400s rough running
« on: August 31, 2017, 02:07:55 AM »
My bike is all stock with about 4,500 miles. Does great for my style riding, but recently has been acting up and I need help. Any time I stand up on foot pegs, ie not sitting, bike sputters and runs horrible but as soon as I sit down clears up. I have removed seat and found no sliced or pinched wires, also have rode around with no seat on and fine when I stand up. Put seat back on and horrible again. I hate throwing parts at something but my question is how possible is it I have a bad cdi, it's the only thing I can see the seat coming in and out of contact with when I sit or stand?
Any direction or help appreciated
