So recently I bought a 2003 f7 private sale. Worst mistake right there So I got my first snowfall and got excited and started doing laps around my door yard. Then my head lights went out. Didn’t think anything of it just kept riding. Then my check engine light came on so I shut it off right there. Let it cool down. Fired it up ran for about 20 seconds then wouldn’t take throttle and bogged down and died and that was it. First thing I did was check for compression. 120 in each cylinder. Not good but should still run. Then I check for spark. Has spark. Check for fuel. Crack the line off of the fuel rail and pulled it over and it’s getting fuel. And yes it is getting fuel past the injectors because the plugs are wet. I changed the plugs still nothing. I’ve had people tell me it’s not the voltage regulator because it should still run with it not having electric start. I thought it was the coil but it has spark. I need help man I got snow coming this coming week and I’ve been itching to ride! Any advice or help would be greatly appreciated!!

Did you lose any other lights and check to see if they are burnt out? If they burnt out it's a good chance your voltage regulator is toast. Download a service manual from countrycat.com and ohm out the stator to rule that out. There is also a few other electrical tests shown in manual you can do.

Just don’t want to buy parts I don’t need. I got told that with this f7 being a pull cord with no electric start it should start without the voltage regulator working. Thing is stumbling me

Yes it should start without a voltage regulator, but I would first remove any led lights or anything else you have added just to rule them out. They could be robbing too much power.

How many watts are your LED’s rated at?

Removed them and still nothing. Not sure what to do. I’ve tried everything. Only thing I can think of is a stator. It has spark it has fuel.

Do You l know what code your check engine light was flashing?

Also is your spark weak or is it bright blue and strong?

You say 120 compression, but if it isn’t starting and you had a solid light I would be taking the jugs off. At a minimum pull the y pipe off and look in the cylinders. Or get a scope camera down the spark plug holes.

Pull the y pipe and post some pictures of pistons. One of the most important thing to do is let these sleds warm up before you take off. The coolant tubes along the running boards should be warm to the touch. This allows cylinders to warm up at the same pace as the pistons. Otherwise you cold seize it.

Yes bright blue spark and I have looked in the y pipe cylinders look fine. Didn’t notice the engine light til right before I shut it off and it was solid it could have blank a couple times didn’t notice
