Just wondering if there is any correlation with high rpm cruising and stater failures. Or if those who have failed staters ride there bikes like they stole um all the time. I cruise between 4500 and 5000 rpms. 9500 when airing it out every 100 miles or so. 2372 miles so far, no problems yet. How bout you? | ||

The stator problem is from LOW RPM, not high. The upgrade harness disables one leg of the stator at below 5k RPM | ||

I seldom see the tachometer go much above the 4000 to 4500 range. I just finished modifying the harness / connectors and installing. I now have to get it to the dealer for the re-flash. But if it limits charging until above 5000 rpm then I am going to be in trouble for sure  I wonder if this 5000 rpm threshold is something that the dealer can lower a bit, anyone know? | ||

I have monitored mine after the harness modification and it does not just cut the 3rd phase at below a certain rpm,(unless my ecm is faulty)the ecm controls when the phase is cut buy using the program that is installed.What the actual conditions are for the phase cut would be interesting to know? I wonder if anyone has read the data from the ecm? My HD mech said he would let me know if he obtained the info. | ||

Certain "conditions" must be met for it to drop one leg. What those conditions are, I don't know but maybe it has to do with a combination of voltage, temperature and RPM....? | ||

Is the re-harness just for the 09s? My dealer said nothing about it for my 08 | ||

It only applies to 2009 and 2010 models, unless you have a 2008 that has had an engine replacement. | ||

I was thinking about the stator problem. I notice when flipping through the manual that the oil pressure increases with rpm. The general consensus is that stators fail if the bike is driven below 5k rpm. I wonder if the failing is due to overheating from low oil pressure. Which begs the question, is there anyway to increase the oil pressure at low rpms? | ||

Why not just downshift and cruise at a higher RPM? | ||

After harness update the volts at idle are the same as before 14.1 so. At cruise 13.4 or there about. Never seen volts go below 13. | ||

I cruise 4500 RPM all day, and my system voltage seems to run pretty normally after the harness. The only time I have seen my voltage drop below the mid 13's was in stop and go traffic in 85 degree weather where you know it is not charging at idle anyway. I am not certain if my stator was replaced when they did my harness, but I certainly saw signs of a stator failure before the upgrade. | ||

Since the harness I have seen voltage drops to the low 12s at idle. It seems to pick up to over 14v during cruise. My relay goes clicking nuts at idle sometimes. ac | ||
| Rob_l |
So voltage drop at idle should happen when ambient temp is high, I'll keep an eye on that. Here in Michigan haven't had many days over 80 degrees yet. | ||

To ride at the RPM's you do, I would never make it out of second gear, then tire wear, fuel economy, engine noise, engine life all become an issue. | ||

Just ride the nuts off it, the majority opinion is that the stator windings overheat at low rpm due to a lack of cooling and high electrical load demands. Thats why all my bikes are on battery tenders, occasionally when riding the 1125R I will change down a gear or two and give it a bit of relatively high rpm. It seems that the 09 onward bikes higher alterantor output has caused the problem. Any 08 owners out there with failed stators. | ||

> I would never make it out of second gear, > then tire wear, fuel economy, engine noise, > engine life all become an issue. I'll remind you, the 1125r is a high performance sport bike  While your fuel and tire wear might change (though I don't think that much for the worse), I got news for you, the engine won't be a wear part on your bikes. My '08 has 40,000 miles on it, and over 10k of those are hard-earned on the track. Lots of WOT, lots of seeing the temp light come on in the summer, lots of heat cycles. That motor is now a bit "tired" -- a few HP down, doesn't quite have the "spunk" of a new motor, but it's mechanically sound and runs like a champ. It certainly puts out way more power than you use. Point is, I don't think you could ever wear one of these motors out. These bikes are dirty whores. They like to be ridden hard and treated badly. Seems like the harder you are on the bike, the better it performs, really. | ||

My 09 CR went for a nice 300 mile run with about 50 harleys and a smattering of other makes. I now have 2500+ miles on the bike. After a glorious sunny day 47 miles from home the engine and battery lights go on. I toggle over to see 12.0 volts. As I continue the voltage drops a tenth at a time. At around 10 volts there was a new message something like 'electrical system failure' then the bike sputtered and died. It died one mile from my brothers place. I pushed it there all leathered up on a hot sunny day. What fun! Sore from a long ride on a lousy seat and now some cardio. I'm too old for that kind of crap. Called my riding buddy, he was having dinner with the ride group. He left them, got his car picked me up and we then went to his shop for my S1. Riding again! Having that spare bike sure takes the sting out of those lazy HD people for not engineering adequate cooling for the 1125 stator. I wish they would have done the stator when they did wiring harness recall two months ago. The S1 has 95Kmi and is now my primary bike until this is resolved. |
