If i was the engineer in charge of fixing this stator mess, I would design a stator that has less power output then the 09's, but more power output then the 08's. I would also beef up the winding so that it could take the heat. | ||

This and threads like it have pushed me over the edge! I just purchased the "add 5 years" warranty coverage. Too many little things going wrong with the 1125's and none an inexpensive fix. My 2 years factory was due to end on the 4th of August. With this stator problem, the unit must be right on the edge of being just strong enough for the job. Seems odd as my 1976 triumph puts out 120w max and this is enough to power all the electrics. Only "extras" on the Buell is the fuel pump, injectors, headlight always on, fans 50% of the time. All the lighting is low power use LEDS (except the head light). The warranty will be cheap peace of mind, if a tech worth a damn can be found! | ||

Tap an oil injector or two onto the upper portion(s) of the stator housing. There are external lines going right by there anyway. | ||

Nigel, add...running the computer, the digital IC display, taillight, ignition, power the sensors (temp and the like), and you have A LOT of electrical things... ...and you are holding Joseph Lucas electrics up as an ideal? the Prince of Darkness? | ||
| Ezblast |
LOL! | ||
| Pwillikers |
How much does an extra five years warranty cost? | ||
| Usanigel |
List price is $1404, My dealer gave a slight break at $1254. Will it be worth it??? Time will tell...... Joe Lucas was always far from the best! Datsaxman. What is the power demand on this beast? | ||
| Ezblast |
I'm debating that exact point! | ||

Did Mt. Diablo with Thomas today - nice weather - entered from Northgate and left into Southgate into Danville Steadily watching my battery voltage drop down to 12.0 from a beginning 13.8 while keeping the rpms in the 5000 to 8000 area - took 680 home because the voltage needed to climb and some constant hi rpm freeway riding did do the trick bringing it back up to 13.4 by the end - I sure as hell don't like that - would getting rid of the harness stop that lack of charging - I'd rather pay for a heavy duty rewind than go through this BS, let the stator fry, then send it in for a rewind. Is the pin connectors the hardest part of the job? Do I need a fresh gasket for doing the stator area? EZ | ||

My bike is still down, waiting for the stator to arrive. I am wondering if many of the engines built by BPR rotax have the same size stators? Perhaps something from aprilia or BMW will also fit, say something putting out a bit more power then the 08's but less then the 09's? Does anyone have a few dimensions for comparison (both for the 08 and the larger 09)? I would need to know both ID and OD. Thanks in advance. | ||
| Tpoppa |
Aj I think you are on the right track for output between the 08-09. From what I have found, the 09 stator is a unique size. A rewind shop can alter the output of an 09 stator in the rewinding process. If I was out of warranty, I would rip out the harness upgrade and have the 09 stator rewound to output 450-470w. YMMV. | ||
| Aj2010 |
Tpoppa, I think that there are a few Aprilia models that are spec'd with 450 watt stators. I just bought an 08 flywheel on E-Bay so if the aprilia part is the correct dimensions then I will give it a try. And remove the harness/relay as you've suggested, but I still need the dimensions of the various parts from some one that has them taken apart. | ||
| Tpoppa |
I don't have the 08 dimensions. This aftermarket RSV stator 'looks' alot like to the 08. Good luck. | ||

So, i took the e b r ecu off, put the stock back on and i took my bike to the dealer. Yesterday was a really nice day (mid 70's) and let me tell you, I had 14v for a good 15 minutes, then started to go down when in town. Took the highway, went up to 13.5v and after 5 miles of in-town riding, I got to the dealer with 12.0v. No way around it, in a 94 degrees day, my bike wouldn't have 14v after 4 or 5 minutes, temps make a big difference! | ||
| Tpoppa |
temps make a big difference! Right, becuase the fans draw a lot of power. With the current ECM flash...CT around 180 degrees the 1st fan kicks on, CT around 205 degrees the 2nd fan kicks on. With both fans running, mine rarely gets above 12.9 even at hwy speed. | ||
| Fresnobuell |
So I did some hwy cruising in 5th gear at a steady 5,000RPM. The IC would show voltages mostly 13.8 to 13.9. I did see it very briefly as low as 13.6 and as high as 14.1. Is this considered normal? | ||
| Dannybuell |
Fresnobuell - you have an 08, yes those numbers are most desirable to an 09+ owner. :-) | ||

If the fans are the big energy draw why don't we also focus on enhancing passive cooling systems to reduce the demand for those fans? The initial reasoning for the pods NOT being of the pass through air flow type was to keep the heat off of the rider. To me it seems the stock setup has heat trapped in the pod until the fans come on and then it blows it out the front. There are two negatives that I can see, the heat that is trapped in the pod also heats the frame and radiator. Ugh! The sustainability of the bikes electrical system is the primary focus and the fans threaten it to some extent. A pass through air flow design might be a good place to start. There should be a clear path for air to move into and out of a pod. | ||

09 1125R at the dealer waiting for the stator (and instrument cluster problems yet to be diagnosed/fixed/replaced). I just got off the phone with the Harley/Buell Help/Warranty people (414-343-8400) I asked if anything was in the works, an improved stator or a more permanent solution then replacing oil/filter and stator at regular intervals until the warranty runs out. John told me that as far as he knew, Harley is not working on a re-design nor do they have any plans to do so. I am thinking that even with the additional money they would get from selling everyone the extended warranty, it still isn't going to cover the cost to them of all the warranty stator replacements (I have less then 7000 KMs and have been avoiding city driving. This is NOT encouraging people  | ||
| Tpoppa |
Danny, The heat is not trapped in the pods. It flows through the engine compartment and passes over an air foil of some sort before it flows out the back of the bike. Actually, think the pods work quite well for cooling. My CT is was consistently 20 degrees cooler than a friend's SV1000S on a recent ride. Temps were in the high 80s. | ||
| Dannybuell |
Tpoppa - "before it flows out the back of the bike" Please correct me where I am wrong. The pod has four sides; the Front, Back, Outside, and Inside. At the back of the Inside is the radiator, fan, and frame. Until the fan comes on air passing through the pod goes through the radiator and onto the frame and eventually the side of the engine. why would you want to put heat onto the frame? | ||
| Skntpig |
http://www.buell.com/_media/images/technology/ride r-focused-design/protection.jpg Looks like it jams heat it into the frame/motor | ||
| Tpoppa |
I've not heard of 1125s overheating, so the cooling system must be working  | ||

Just called my dealer. They finally diagnosed the stator after a week. They THINK the stator is on backorder although they have one "on order". | ||
| Ezblast |
So Justin - do you have a long term report? Anyone else do this? EZ | ||
| Keef |
Guys I cannot say who gave me a source and part number for the backordered stator bolts.But here you all go they are from McMASTER-CARR.com part number 91290A422 now the factory bolts are grade 10-9 and these bolts are actually stronger they are 12-9's which my source says is just fine hell I was told that if they were in need they would use them on the race bikes.They didn't havw any on hand either...  | ||

After doing 200 miles on my rewound stator I do have something to report. As I mentioned before the volts stayed between 13.4-13.8 but just yesterday night something happend, the volts shot up past 17 and stayed there for the longest ass time until the fans came on and once they did the volts dropped to 11.8 in a minute at idle...there is no way that it could be the stator id be so pissed if it was, soooo what I am doing now is im putting in a new voltage regulator and a new battery then there should be no excuse...if it still does crap then im pulling out that POS sub harness | ||
| Lucky_jim |
Damn, that's weird. I think a lot of people were banking on a rewound stator fixing everything. Can you just yank out the new harness though? Wouldn't you have to downgrade the ECM to an earlier version since they're now designed to use the harness? Or so I thought... |
