Hi,
I got me an 05 yfz last fall and I have had nothing but issues since I got it. When I first brought it home, it was running fair. Since I was used to riding quads with twist throttles, I changed out mine ASAP. I also removed the air filter and ran with a k&n. I made no changes to needle position. I had no issues at first, but soon a development began.
The quad would start fine cold, and sounded fine running (except the lean popping), the engine began stalling if I held in the clutch. I tried to adjust the idle, but seemed that no position would help. The problem progressed to the point that I began to have issues starting the quad, even warm. A couple of times I even got stranded.
The time I was stranded I tried many times to get it to start, and ended up killing the battery. But I did not know if it was dead because I was hearing a clicking noise on a solenoid somewhere around the battery. So I returned the quad to the dealer for warranty work, and told them the story.
I was told that my battery was dead, but there was nothing wrong with the idle. It was returned to me with a charged battery. I took it out near my home, where it ran decent for a couple hours, then the symptoms began to return.
I returned the quad to the dealer again, complaining of the constant stalling. They told me that the removed the carb for cleaning, noting that there is a preservative that is put on the quad at shipping that was notorious for clogging the jets.( yeah, ok...)
I returned home, and the quad ran fine. the same story repeats only this time, I cannot ever get the quad started at all. I am trying to find a solution since my warranty is expired. I did some research and found a couple things. 1 was the jetting at factory setting. I moved the position to #5. second was the changing to twist throttle. The instructions that I received never even mentioned the throttle switch in the thumb throttle. I recently found that I was to clip the switch and connect the wires, so I did so.
I suspect a fuel flow problem. So I checked the floats in the carb, they seem fine. I did find a little bit of contamination on the needle, cleaned and re-installed at the new setting #5. I verified fuel flow to the carb, and I do have new gas. I verified that I am getting spark at the plug. I reset the idle screw to 2.5 turns out, as some recommended.
I suspect fuel starvation since I get no changes durring ignition.
One thing was weird is I did leave the fuel on for a few hours and I returned to find a pool on the floor.
I hope one of you experts could help out a newb get better at maintaining my awesome garage queen.
thx
