Let me start by saying my quad is a 2008 ER. I bought it used but the guy hadn't even put an entire tank of gas through it. It looked absolutely brand new in every aspect. It was completely stock, so I know the history of all of the mods. My quad now only has about 15 or 20 hours on it. I installed my hotcam stage 2 yesterday and drained the oil. Today after work I added non synthetic oil, put the tank on and went to start it and do my break in procedure. Before I installed the cam, my quad had no problems whatsoever starting. It always started instantly, cold, hot, every time. I tried to start it today and it took about 15 seconds or so and finally started. So like hotcams said I took the rpm straight to around 3000 rpm. I was going to do 30 minutes of break in. I was going to do 10 minutes stationary with a fan blowing on it and then lightly ride it for the last 15 to 20 minutes keeping it around that same rpm. After it ran for about 30 or 45 seconds, it cut off. I removed the valve cover to inspect and manually turned over the engine via the crankcase hole. Everything spun freely and looked fine. I put the valve cover back on and tried to start it again. It just turned over and over and wouldn't start. I removed my spark plug and checked the spark and it looked fine. I know the carb or nothing is clogged because I just rode the quad a week ago and have rode it 3 or 4 times this year already and didn't have a problem with it starting or running poorly. So I decided to look at the compression. I did a compression test, or a decompression test I guess you could say. After letting it spin over for around 5 to 8 seconds, it was maxed out at around 38 psi. This was with the throttle closed and I didn't try it at wide open throttle. I'm assuming this is low and it should be around 55-65 like the 06-07? I checked the valves cold with the stock cam and they were perfect. I rechecked with the hotcam and they still seemed to be right on the money. I decided to put the stock cam back in and do a decompression test to compare. The stock cam gave the same results, maxing out around 38 psi. That's where I'm at right now. Can anybody help? I just don't know why the decompression is that low and why it randomly cut off like that. I also started it one other time and it did the same thing? You think since I had turned the idle up like that, it just ran for a little and then flooded itself? The only other mod I have done since it had ran is added a HRC head pipe. Any help or suggestions would be greatly appreciated.
