Last year the ECU on my 09 versys took a crap only after 2,000 miles.
At the time I wasn't exactly sure it was the ECU as my ECU was telling me the problem I was having was the tip over sensor switch. It wasn't until I gave it to a motorcycle mechanic friend of mine that he found it was truly the ECU. At the time we couldn't find any ECU's to buy used and I didn't feel like spending the waping $450 dollars on a brand new one. Soooo... he put a 650r ECU in instead. it fixed the problem but now I'm starting to have stalling problems with the bike and I'm beginning to wonder if the 650r's ECU is causing my engine harm.
The stalling problem as of now I feel has been a slowly compounding one. I first saw it on a trip I was on at high altitude in cold temperatures. This after having ridden the bike with new ECU for at least 2,000 miles with no issues. When the bike and temp outside were cold it would start but then instantly die. It would run so long as I opened the throttle and ran it at 2,500-3,000 rpm to warm it up. I did also notice that the bike was rapidly coming out of the "fast idle warm up" rpms. The problem persisted so long as it was cold outside, but not when it was warm. The problem has recently shown up now even when its warm outside and
when the bike is warmed up. So now the issue is it needs to be assisted on starts even on warm days, once warm (20-30 minutes of riding) it rides fine, but pulling up to or sitting at stop lights it will still periodically stall at idle. I have to shut the key off and reset it in order for it to start up. Just to clarify my hot idle speed is above the 1300 rpms suggested
. I have 8,200 miles on it, and though it is recomended at 7,500, I have not changed the spark plugs or cleaned the air filter, but can't imagine that would cause this. I also have an after market slip-on exhaust installed.
Any thoughts or experience with this kind of issue?
