When I sold my 63 Triumph back in 04 I didn't expect to end up here, but, a commuter blast, then an XB9s and now an 1125cr. To be accurate, the XB9s is really more than I ever needed. But, bikes are best light and quick and I am drawn to the lighter and quicker. I does handle better and obviously it's got an HP advantage. I can't say goodbye to the XB, I kept it registered and insured. But, if the 1125 keeps performing, I'm cleaning house. Beautiful summer weather here in CT - dark and foggy in the am, clear and bright on the commute home. Long live the american sport bike. | ||

glad to hear you enjoy it! Ride safe. | ||

I'm sure you had a good reason for selling your '63 but... Keep the XB for now until you get the 1125cr sorted out and set up for the way YOU like your bikes to be. Good source for parts are our sponsors on this board. Excellent service. | ||

Ditto on Two_seasons advice; "Keep the XB for now until you get the 1125cr sorted out and set up for the way YOU like your bikes to be." The drastic differences between my S1 and CR has me riding the S1 in town for better fuel economy. The S1 has drag bars, it sits up a bit higher than the clubmans making it easier to ride in traffic. The S1 also has a greater presence in traffic with an empty D@D megaphone muffler that has been welded shut. The CR loves higher than S1 engine speeds and less urban riding to be happiest. :-) | ||

Phwx2, If I had a 2009+ Buell 1125R/CR I would seriously consider replacing the stock (shunt) voltage regulator with a Series Voltage Regulator to avoid the stator overheating issue the bikes are plagued with. The 2009 stator's were upsized to handle a larger electrical load 500 Watt (37 Amps/Phase) versus the 2008 432 Watt (32 Amp/Phase). The larger capacity unit generated more heat and basically cooked the insulation of the windings allowing the wires to short out against each other. The stator cooling was NOT addressed. Idling with large current draws is apparently the worst condition because there is no oil cooling of the windings (oil spray within the engine). The Eric Buell Racing low output alternator (really a generator) uses the smaller 2008 capacity stator AND has an oil spray cooling hole to spray (cooling) oil on the windings and help cool them down. This link describes the problem and another possible fix: http://hildstrom.com/projects/buellstator/ It attempts to address the real problem - insulation breakdown of the windings by using a higher temperature insulation and added some air cooling holes in the rotor. He also uses a series voltage regulator that disconnects the stator windings as the voltage goes above 14.4V, so the windings see ZERO amps (and run cooler). The problem with the series regulators is that when they disconnect the stator windings the voltage climbs very high (75 - 120V) and the electrical components in the series regulator must be good enough not to break down (expensive $$$) from the high voltage. I have a 2008 Buell 1125R and I curse the damn thing in the winter because it doesn't have enough capacity to run the motor, lights, heated grips, heated liner ... the voltage drops below 12V at stoplights and is basically discharging the battery. Even at cruising speeds, the voltage is barely above 12.6V due to all the electrical demand ... but it doesn't overheat! To summarize once more, if I had a 2009 higher capacity unit, I would invest in a very good series regulator (about $160) since it allows ZERO amps to flow when the voltage goes above 14.4V and stator windings are disconnected, the stator windings should run cooler. If I had the 2009+ stock stator and it overheated and shorted through the winding insulation , I would probably get it rewound using a higher temperature insulation, then add a series voltage regulator. I might try adding the cooling holes suggested by hildstrom as well. There is probably an method to add the oil spray cooling in the stock rotor as well. | ||

Thanks for the support and wisdom. 1) Sold the 63 because I was wrenching more than riding by a wide margin. I'd rather wrench on the cars. 2) I do agree that the XB (like your S1 is more user friendly in traffic and city congestion) I haven't stalled a bike in 20 years and stalled the 1125 3 times. The goal is to find all twisty backroads where ever I go. 3) Noid, weep, stator, fuel/engine light in cold, boiling fuel - I've been reading the 1125 site since it opened. Read the advice. I guess I'm willing to deal with it for the lightest quickest USA bike ever made. Thanks for the welcome. | ||

Yup, you learn to give it a small shot of gas just before you take off. You can also stall it by giving it too much gas too fast when idling. Snap the throttle open while idling, and you can kill it. I don't do it. I see no reason to rev my engine. |
