Just got my EBR rotor in the other day and I was having a close look at the machined orifice that squirts the oil at the stator. It is very small. Has anyone head any further stator failures after installing the modified rotor? | ||

It is very specifically sized for the right amount of mist to cool the stator best. Tons of testing to determine the optimum size for cooling and then durability testing after that. Also very hard to make a precision hole this size in a hardened part; it would be easier to make it bigger. Of course there is probably someone on the internet who knows better and will suggest you drill it out to a 1/4", so you can both flood the cavity and blow the main bearings. | ||

No, I'm not going to drill it. It's already on the bike. It just seemed very small for the amount of cooling it will have to do in Toronto's purposely made traffic jams. | ||

What size is the small hole? I know it starts out at about 1/4" then goes to a small hole. | ||

Why anonymous???? | ||

That Anonymous post was by an EBR employee. The info does not get any better than that. | ||

LOVE IT!!... Thanks Anony. This is definitely one of the cool things about owning a BUELL. I must admit I thought the same thing though when I saw the hole. "damn thats tiny, wont that just get plugged up?" But then I realized I am NOT an engineer and went about riding and enjoying my bike some more. | ||

Wish HD would do this as a factory fix... So i expect i'll be doing my stator again in a year or two when it fails again. I even offered to buy the part from EBR, but would lose the extended warranty. Extended warranty paid for itself w/ the stator and 10 days of bike rental. GL! | ||
| Captjoe |
Mine is still under the extended warranty. I can't see how upgrading to a better part would void the extended warranty, however, even if it does, it must only void the parts directly related to the stator. At the moment, I'm hoping to not have any more stator related issues!  . I just can't handle any more 250 mile tows. | ||

Can somebody stick a small drill bit in the small hole and tell me what size it is? EBR drilled mine out but the small hole did not go all the way through so I drilled it out to 1/4" hole now I find out thats to big I will have to fix it but I need to know the small hole size. I saw a picture with a 1/4" hole thats why I drilled it out. | ||

Dennis - i hope you are joking. See above post from anony. GL! | ||

I guess you could braze it shut, then drill the right size hole in that, if you can follow the right path. I'm not sure it's a straight hole. I think it was EDM machined originally, it is a complicated process. | ||

It's rotating mass...brazing will require balancing. You may think it's not important...but how fast does this thing rotate again?? It sounds to me like it's a tapered hole by design - those pesky engineer types figure volume versus velocity, I'm sure, when they're trying to figure out the best size and shape for the orifice. Not to mention angle... | ||
| Dennis_c |
I have the angle the hole was not tapered I would guess that they used a drill bit with a small tip on a 1/4" drill bit. Most of the hole was all ready 1/4" I don't now the name of that kind of bit. I am going to tap the hole not all the way through and make a plug with a small hole with loctite | ||

I hate to say it, but maybe you should just chuck that one in the bin and buy another one and just install it as it was delivered rather than mess with it? | ||

I believe its 3/32. | ||

| Dennis_c |
What was wrong with the replacement rotor? Thanks for the 3/32 | ||
| Ratbuell |
You tell us...something made you take a drill bit to it instead of asking the manufacturer if it was right or not. | ||

"But what fun would that be? All those future "I got a replacement rotor but it still sucks" posts that we'd never get to read..." I predict a future post from Dennis_c will read something like this : "Motor blown for no apparent reason....WTF?".....LOL!! No offense but ignorance is bliss. | ||
