this mite help you guys with 09/10 stator issues http://www.erikbuellracing.com/store/models/1125r/ moderate-output-low-heat-alternator-kit.html | ||

Thanks for the pointer. There is already an active thread on this subject. http://www.badweatherbikers.com/buell/messages/290 431/657739.html?1320534987 | ||

oh...sorry just ran across it on the weekly ebr page browse.. | ||

I think it is awesome that EBR is fixing the issues the 1125's had. They have no responsibility to do this after what the Hardly Dickison F**ktards did to Buell. I think it is being done because Erik/EBR values his/their customers. I am super happy with my clutch kit. | ||

> EBR is fixing the issues the 1125's had. I have a bet with a friend on how long it is until the first post complaining their battery won't stay charged. It's a fix to the electrical failure of the stator, but still won't help the rider who insists on using their bike to lug between stoplights or ride down the highway at 65 in 6th with HIDs and heated gear. | ||

HIDs use less power than OEM lights. | ||

For the R it's same amount. They were spec'd with 35W bulbs to begin with. All in HIDs do use more due to inrush on startup...... | ||

I have ordered one of these kits for my 09 track bike, can't wait to fit it and rest a bit easier. | ||

I wonder if the EBR LiIon battery makes a difference as well? I bet it has a lot less loss in charging, and might very well be able to scavenge a charge even when the bike voltage is well below 12V. | ||

EBR Rocks! | ||

The load balancer is presumably a switching power supply. These devices can be thought of like an infinitely variable transformer, and can give more volts at less amps, or more amps at less volts. In theory. Now that I think about it, it would only work if there was another terminal on the battery, one direct to the stator. And now that I think about it just a little more, it could help a little still. So where a lead acid battery needs 13.2 or more to be able to charge, you could still be charging this Li battery at 12V or less if you wanted to tune it that way... Not sure if 12V operating V+ bus on the bike would just work, or if it would introduce other problems. | ||

@Reepicheep -- what "load balancer" are you referring to? I've been following the vreg threads and I haven't seen anything that would make me think that anyone is offering an implementation of a real buck/boost regulator. | ||
| Reepicheep |
The load balancer is integrated into the EBR Lithium Ion battery. http://www.erikbuellracing.com/store/parts-accesso ries/electrical/lightweight-nano-teck-battery.html The more I think about it though, since it doesn't have a separate charging lead, I doubt it has a switching regulator in there. | ||

I like the way you're thinking, but you're right -- that's no switching regulator. It's way too small -- small enough that there's just no way that anyone could fit a big enough inductor in there to yield a real switching regulator. I've crunched some numbers for designing a true switching design, and it looks like the inductor needed for the design could be as big as that Li Ion battery. I'm not sure that's a solution that most people would be eager to accept. Although it might be OK for a street bike, adding inductor mass won't appeal to race teams who are trying to decrease weight. They'd prefer a stator with marginal output at low RPM and not worry about it as they keep the revs high. After all, they only need enough power to run a race bike, and without lights and accessories, that's not much. For them, the 2008 charging system is a CHEAP solution that works. BTW, I agree with your previous posts that a series vreg or a true switching vreg is going to be part of the definitive answer to the 09 stator problem. The ugly truth is that it's not in any manufacturer's best interest to solve the problem. They rely on P&A as a revenue stream, and they're more interested in selling replacement stators than in admitting that their decision to use a cheap, low-tech shunt vreg that puts the stator into a 100% loaded condition is the basis of the heat problem. I don't see a series vreg or a buck/boost inductive switcher coming out of anyone whose profit model involves selling parts kits. Our only hope is to look to the independent aftermarket for a solution. |
