Okay here is an analysis of my 45 minute ride.
8:00 PM leave the house
8:00 to 8:20 PM no problems at all
8:20 - 8:23 PM Major problems, RPMS are very jumpy, losing power, hard to control throttle
8:24 PM Open up gas tank for 25 seconds
8:24 PM - 8: 34 PM no problems at all
8:35 PM- 8:40 PM same problems, to a lesser degree than the previous
8:41 PM open up gas tank for 25 secondsl
8:42 to current, no problems
Any ideas?

That's a good way to have two bad ECU's.Tuscon_Dragon wrote:It might be your Control module . breaking down when the bike is hot, and then running fine after cooling down a bit is the first sign they are goin bad.
Easiest way to check is if you have a friend with the same bike, switch em out and see what happens.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

Especially if there is a short somewhere causing the ECU to crap out.Sev wrote:That's a good way to have two bad ECU's.Tuscon_Dragon wrote:It might be your Control module . breaking down when the bike is hot, and then running fine after cooling down a bit is the first sign they are goin bad.

So, every time you open the gas tank, the problem clears for about 10 min.? That would be an obvious sign that you have a tank venting problem. Another clue was that in your earlier post, you were having to let the bike sit before it would run again. If you get a vacuum in the tank, it will eventually clear itself if the engine is not trying to draw fuel.intotherain wrote:Okay here is an analysis of my 45 minute ride.

I have a very similar problem with my suzuki bandit, except shorter intervals when the problem would surface. It would start when i let the bike sit for 5-10 minutes. I tried running it with the gas tank open at home one day and the bike still stalled.flynrider wrote:So, every time you open the gas tank, the problem clears for about 10 min.?

A problem with an ECU is typically caused by one of two things. A short, or overheating.Tuscon_Dragon wrote:Sev wrote:That's a good way to have two bad ECU's.Tuscon_Dragon wrote:It might be your Control module . breaking down when the bike is hot, and then running fine after cooling down a bit is the first sign they are goin bad.

Either way, if you do not solve the problem before installing a new ECU you will likely write off the second one. If it's due to a short you will write off the second one very fast, if overheating it will take longer.
Make fun of me if you want, but I'm not going to owe my friend $900+ for a new ECU down the road.
