Ok, since I can't currently search the old content, I'll start new thread...



I have 78 CX500 with 30K miles. Last night after about 40 minutes riding (last 15 of which were at about 75 MPH highway) it suddenly bogged down while I was on an interchange. No power in the high RPM band. Fortunately I was just 5 minutes from my destination, and pulled off the very next exit and slow-speed through the back streets.



This morning, after 14-hour rest, behaved fine on the 10-minute ride to work. Based on what I've read on the old site in the past, I would suspect that this could be a stator problem? High-RPM windings doing something when it's too hot? (Air temp was mid-80's yesterday)



Looking for some input. Thanks.

Heat related problems can be hard to diagnose.My 1st instincts would be coils or plugs or plug caps so click here fr coils

I haven't quite figured out all the buttons on this forum yet. But, Brian, did the bike run OK when you slowed down and took the side streets? There could be a could be a couple of reasons for the drop in power. The stator's high speed winding is one that you mentioned. Another would be the CDI got warm and cut out the high speed side output. Another could be the coils got hot and did the same thing. Do you have the air dam in place by the thermostat? That, I believe helps to direct the heat from the radiator around the coil area keeping them a bit cooler.

Sounds like the stator to me, it happens too often for me to say otherwise. check the stickies on the global forum.

hmmmm? no idea, good luck with it though.

The bike does have all its parts (air dam etc). The behavior happened again yesterday, though this time it was due to low fuel. I switched over to reserve, but the bike took about 3 times longer than normal to get back to full power (and I was on the freeway). Behaved exactly as on Sunday night. The whole heat thing my just be a red herring, I may actually have something wrong with the fuel delivery - could be water or something sticking in the carbs.



I am going to put some dry-gas in and some Sea Foam and see if that fixes it. Easy and cheap. If it gets me through this fall, then I can see about a full carb cleaning and some other TLC on the bike.



Thanks everyone!
