I know I know ANOTHER stator. Happened on the way to work today. Everything was good checked my coolant temp and OH NO battery reading 13.2 Normally it's 14.2 it rose slowly to 13.8 then went back down to 13.1 got it to a gas station it died. Won't start voltage system error so bummed. : ( AAA jumped it for me and followed me to work, good people. So now I guess it's time to do everything. Valve check, plugs, custom rewind, new R/R. And if I can sneak it by a new Erik Buell Racing ECM : D Well my 2nd stator lasted about 14,000 miles so we'll see. It did last longer than the first that only lasted about 1500 miles

If your stator is bad I don't think you would have been able to ride to work. Maybe you just have a bad battery.

As I recall when my stator fried, I was getting some lower then usual battery voltage readings. Up then down then up again..... finally descending with no recovery. I did make it back to my buddy's garage, the bike promptly died in his driveway, showing slightly over 8 volts.

I've just installed on 08 stator and flywheel as well as a Compufire R/R. My battery voltage is now around 14.6 (as low as 13.9 and as high as 14.8) It seems things are working so I feel comfortable with taking the bike on an 8000 Km trip down into California in a few weeks. I hope your solution works out for you though.

After AAA jumped the bike I rode to work, the AAA guy followed, got off work at 10 pm. Bike started : D rode home kept an eye on the bat gauge bounced between 13.2 - 14.0 I crusied at 80mph in 4th gear all the way home about 33 miles. Gas light came on got gas it started back up and I made it home bat gauge still reading 13.7 ave. Checked battery with multimeter 12.45 volts. It's late now so the battery is on trickle charge and I'll do a stator check in the morning. The coolant temp on my way to work was at 200. Coming home 175. So I'm pretty sure the hot afternoon heat has some part in making the bat/stator act funny. I will also check the "up grade" harness and relay also tomorrow. Okie dokie till next time I'm going to bed

Both your fans are running in the afternoon, so voltage is going to be low. If you run your high beam like some, then forget about it.

Any stator problems on the 2008? or is it just 09's

99.99% are the 2009 model year. The 2008 had a lower output stator so it doesn't generate the heat as the '09-'10 you just have to watch fir the IC drain if it has not been replaced yet

Johnson My speedo has the gear indicator..does that mean it was fixed?

Just got the bike 2008r 1300 miles

Dealer showed me all recalls were completed*

Ok on my bike I connected one terminal to the ground on the battery and checked each wire from the stator, the meter read infinite (also it did not beep) so I will assume for now the stator is not grounded out. My meter has
200/audio tone
2K/ diode symbol
20K
200K
2M
20M
Settings for ohms. Which setting do I use? I know I should know but not exactly sure. I used the 200/ audio setting and get 00.8; 00.7; 00.7 book states
0.1-0.3. Still need to try the voltage test

200/audio = maximum resistance the meter can report is 200 ohms - this is the most sensitive setting
K= 1000 ohms x the meter reading (13 meter reading = 1300ohms) this is less sensitive than above
200k =200,000 ohms x the meter reading (13 meter reading = 2,600,000 Ohms)this is less sensitive than above
M= Millions of Ohms (2M= 13 meter reading x 2,000,000 =26,000,000 ohms)
you want the meter set to the most sensitive "scale" so it can report the smallest amount or resistance or in this case the continuity (connection)to ground.
set to 200/tone - and receiving no tone or zero on the meter is a good thing - you may want to connect between the stator and a chassis ground (the engine)- (not the battery) it might be giving you some kind of resistance within a circuit the battery is connected to (the voltage regulator???!) or the Resistance of the battery itself ...isolate the circuit you are testing - otherwise you're reading can/will be mis-leading...good luck

Thanks nuts, I will do that. Also with the bike running and checking the bat voltage (everything plugged in) the meter says avg. 13.5 volts. I can hear the bike change running tone a bit when I unplug the stator. The bat drops to 12.5. But I get nothing when I probe the stator connector with the meter. As in no reading for volts. Guess I'm doing that wrong too

the voltage from the stator is AC (Alternating Current) NOT DC (Direct Current...like the battery)
make sure you have your meter configured correctly- usually the probes may have to be plugged into the correct sockets on the meter - for sure the knob/switch for measuring must be changed to "AC"
each leg (yellow wire) is a voltage source...each leg should give you a reading when the engine is running...you should get (3) similar readings in AC Voltage...it will increase with engine RPM

Looks like i need to go over to Nuts place sometime and have him show me how to use my MM...

very helpful info - thanks nuts!

Jc - How old is the Battery?
"...with the bike running and checking the bat voltage (everything plugged in) the meter says avg. 13.5 volts. I can hear the bike change running tone a bit when I unplug the stator. The bat drops to 12.5..."
that sounds OK to me - maybe the battery won't store the energy it's getting from the stator - if it older than 2 years ( figure that the factory/Dealer had them on the shelf for awhile) - you may need a new battery.

Thanks for all your teaching me nuts4mc. I'm more of a mechanical guy and limited electrical. The battery is the original from factory. It made it thru the first stator failure. I charged the bat all night and day while I was checking the other stuff. Rode the bike to work with fingers crossed : ) the bat gauge floated between 13.5-13.9 the whole way. Even hit 14.0-14.1 idling at light. After excelerating to cruise speed it would drop back down to the avg of 13.7. Not sure if it could be the r/r possibly? Or bat. I'll change it out on my weekend (tue-wed) I did notice that with the bike running everything plugged in when I grabbed the stator plug to unplug it from the harness upgrade the wires are very hot but the r/r is still cool. It has never got hot I have always been able to touch it thru the tail opening behind the r/r and it's not hot. I have been blessed with not having all the stator issues as some people here. Again nuts thanks for all your very important info you give me I really do appreciate it as does everyone who reads it and learns from it

Thought I would do my update here since I started here. Ever since my bike died the other day and had it jumped this is what I have noticed. Bike still starts and rides fine hum go figure. I watched the voltage while riding to and from work the past few days and it's kind of weird. Upon excelerating the voltage will drop down to about 13.2(avg) and will climb up to 13.9(avg) while cruising (70-80mph; 6th gear) here is the really weird part when I let off the throttle and stop at a light the voltage will go up to 14.0-14.2(avg). Also if I keep the revs high the voltage stays around 13.6(avg) if I drop below say 5000 rpm the voltage will rise to 13.9(avg). Tonight I did pull off the seat and tail section, found the batt. terminals a little loose(tightened of course). Also I could move the ground at the fuel tank again tightened. Tightened the solenoid connections. Also I pulled the harness upgrade plugs and sprayed wd/40 and cleaned both of them. I'm wondering if it was just a ground that was bouncing around that caused all my issues the other day. But on another note my wife says I should still pull the stator and send to custom rewind just before I leave for my 2 week drill with the reserves so it can be done since I won't be riding for 18 days any ways. And since it'll be apart I'll probably be doing the valve check, oil change, and probably belt replacement. I have about 16,500 miles on the bike now

Just replaced my burnt relay from the harness and my volts will start out at 14.4 then go down to 12.1 while waiting at the lights, then fluxuates between 13.3 and 12.2. Tested the stator and it's still reading good at 3k Rpms, so I don't know if maybe it's just the way the bike runs? At the stop lights my battery light comes on once in a while and I'm on my 3rd stator so I'm hoping it's just the bike lol.

My stator, #2, just died. Last one was just replaced in april with maybe 2500 miles on it, and while on vacation. : ( thinking about replacing it with the 08 assembly. Total milage on my bike is just under 7k and its an 09. Did shed some tears.
