When my bike is cold it starts fine and runs great but after 15-20 mins of riding it starts to bog then catch and eventually stalls out. Sometimes it will start again after I fiddle a bit but then after a bit of riding it does it again till eventually the bike won't even start anymore. After the bike is cooled off it'l fire right up after a couple of kicks and seems to run fine . I've tried fiddling with the wiring in case it was shorting out on the frame and I also thought that maybe it was a fuel problem so I checked the fuel lines and made sure the tank wasn't under vacume. I also stripped the carb and cleaned it all out really well. I recently changed the coil with a used coil off a kawasaki KX 80 because there was a broken wire on the coil . I'm going to get another used coil today hopefully and try it but if not I'm going to order a new coil.
Someone told me that it could be my coil is cracked and that if I spray water on it when the bike is running I'll see the coil sparking all over the place ?
Anyways I don't think it's a carb problem or fuel problem . I think it's electrical but aside from the coil and a little mysterious electrical box with wires coming out of it (CDI ?) and the magneto there's nothing else electrical on the bike .
If anyone has had any similar problems or ideas as to what is wrong pleaseee post cause this is seriously messing up my riding fun and making me dislike my bike . I don't like pushing it home. The next time I'm bringing matches and if it happens I'm gunna have a BONFIRE!!! (just kidding....or am I ?)

Well I got another secondhand coil and put it on and fixed up a few other things then went to try it on the trails. Got 50 feet and the bike bogged and stalled. Fired it up again and it bogged and stalled immediately. It seems to do it at 1/4 to 1/2 throttle and I noticed that other times to. Soooo I don't think it's the coil now . I'm at a bit of a loss what to try next. Help pleaseeee!

OMG ignore anything you read. I'm such a dummy I think I fixed it but it's to late to take it for a good ride but I went for 5 mins and the bike was fine . The other day when my coil initially broke I plugged a hole in the carb not really knowing what it was but I think it was a vent for the bowl . So fuel was having trouble getting into the bowl cause it was getting pressurized . I pulled off the plug and just put a fuel line and routed it down under the bike . Man I feel so dumb . I pushed that bike for a mile because of this......
