I changed the oil in my bike Friday night, I've done it before so I didn't do anything other than normal. It ran fine for a few days including earlier today. It's not leaking anywhere. But I came home on my bike this afternoon after a 30 minute ride and had no problems, but when I went to get on it again about an hour later and hit the ignition button it made a loud pop towards the front of the engine, the oil light came on, and now it won't turn over. Any suggestion as to what could have happened. Again it wasn't leaking any oil and had ran fine since Friday

Hopefully you haven't blown a seal or piston. Sounds serious if the engine won't turn over.

That's what I'm afraid of, it's just odd that it ran fine for days and up to an hour or less before this happened and then all of a sudden "boom", oil light on but not leaking anywhere, and won't turn over. I've had nothing but problems out of this bike since I bought it in April, I paid $3300 for it from a friend who I know took great care of it, and I've spent double what I paid for it since then trying to get it right. I've probably got $10k in it and couldn't sell it for 1/5 of that right now

I had switched the map on my power commander and didn't like it so went back to the previous one I was running, I friend of mine had the same problem once and said the other map caused it to run to rich and left gas built up in the exhaust and when I started it back up that boom was the gas igniting, he says the spark plugs or maybe even just one of them was fouled out due to that. I'm gonna check them and see if that might be the problem

so if it were me I would assume that the power commander map is no good or the physical memory in the power commander has a dumped, this sometimes called a loud pop and sometimes it causes the bike to turn over but not run what I would do is start with a zero map and a power commander and then I would go from there to see what the bike actually does Then let us know what happened

Okay so what I would do the start with the power commander map you may have dumped your physical memory in the power commander which often leads to pop in the bike not running again this can be fixed by updating the firmware and reloading the map. I would start with the new map first see what the bike does then do the firmware let us know what happens from there 20130905

Figured out my problem, I had a friend helping me because I got called away for 15 minutes or so and in my absence he didn't remove the oil drain plug, he removed the one on the right side of the bike that's to the front of the clutch basket, no wonder he said only about a.half cup of oil came out. But when replacing that bolt/plug he broke the head off, and I don't know what it's called to replace it. It's got a 17mm hex head on it but the threads only extend less than a half inch into the cavity where it goes. Needless to say my oil didn't get drained and it got a lot more mixed in with it which caused my bike not to run. I realized what happened and removed the correct drain plug on my own and drained all that crap out and filled it back to the proper level with new oil and when done it fired right up (with a little help from some jumper cables) due.to trying to get it started so many times running the battery down, but everything is fine now and I took that Yoshimura exhaust off and put the stock exhaust back on it and it's got twice the power with the stock that it did with the Yoshi, it's running better than ever and I still haven't put the PC III back on it with the stock bike map

I'm glad you got the oil figured out but that was not your problem sorry to say. Probably the power commander. You sound new to the power commander world and how performance mods work on a bike. Changing the exhaust back to stock returns the bike to proper running If the bolt on mods are not adjusted for , you lose a lot of power, torque, and throttle response throughout the power curve. I don't care what your map says it is. If it is not tuned for your bike then you do not have map, period! You may have a temporary something to hold you over until you get it dyno'd but that's it. People have the misled information that you can put a map that your friend had in your bike and it will operate fine. Think again. You want the mods to allow faster more power throttle response speed ride enjoyment then it must be done right. Not half ass. I have tried telling many on this site about this and many people's ignorance and thinking they know better leaves them failing yet again. Anything you change affects the air fuel ratio and if that is not right then your wasting your money. Since money seems to be the most important thing for many of you. If your not going to do it right because of money then don't waste money by not doing it right. twisted throttles brings me smiles

I took the power commander off when I had the problem of it not starting and it didn't even attempt to start until I fixed the oil issue since then the stock bike has been working better than ever. When I had changed the map and rode it right before it quit on me, it was blowing clouds of white smoke out the exhaust...which I now know was the oil because once I got the oil level correct it did the same thing for about 15 minutes until it burnt all the oil off and it stopped smoking. I put the stock map on it this morning and holy shit what a difference that made, I was greatly impressed with just stock compared to when I had that Yoshimura on it but now I'm thrilled with it, I realize it needs to be tuned on a dyno to get it exactly right but hell it's better than it has ever been so I'm not complaining til I get the money for a custom map, there's a certified shop about 40 miles from me. I understand the air fuel mixture ratio because of rejetting the carbs on my dirt bikes and quads that I've raced over the years every time I put something different on it

and I can understand the smoke. As well as a stock map being put back in but really you'd be better off disconnecting the power commander all together if everything is stock so that the bike can use the ecu and the other sensors to adjust for temp variances( auto tune) feature. I bet you got more bottom end power back too right. Wait til you see how much further you go on a tank of gas
