Not sure what you mean by 'coulomb weight' in connection with the oil. I've always understood it to be a term refering to capacitance where 1 Farad is charged to a potential difference of 1 Volt?

try column



But far more importantly, the 'column weight' of oil under centrifugal force must be considered.

(to maintain the hydraulic integrity of the column of oil within the drilling.



Youth of today in the days we had things called fractions before these new-fangled percentage things and there decimal points came along

Ahhhh ......cheers Barney I'm with Pash in thinking that Mr Bernoulli won't provide much suck

This may well have an effect, and as the RPM increases so does centrifugal force resulting in a pressure difference between gallery and drilling, resulting in increased flow through drilling

That’s the theory. In practice how much of a difference this really makes is

Had a good look, but seems Bernoulli hasnt registered on the forum
He's name has also been removed from the 'Perminent diners list'
Shame, could have done with some theory to explain, and help with spelling
See: Flow Phenomena in Cake Washing Driven by Mass Forces Flow Phenomena in Cake Washing Driven by Mass Forces (Franky Ruslim) P.63
Its only a one page extract, but the theory is kind of where my thoughts were.
Towards the bottom of that page it says
a low pressure feed to a rotational jet will cause 'Streaming'
Which, given the ease of fitting a relief valve on the crank end,
may have formed part of the original design variants?
and not introduced until failure numbers dictated they came up with a 'Out of warranty fix'.
The 'Oil Jet' Rotor Mod
(from the conveniently designed 'open ended gallery' with feed supply ready)
may have been be simply cost cut in production, and then withheld on cost grounds when considering recall costings, in a depressed market (at a point where, a decision of fate, was most likely historic).

'Dont tell Em Pyke'

If You increase flow thru the new orifice, whether due to a rotational or venturi effect, then you run the risk of affecting the things that the oil is supposed look after, ie all of your crank bearings.

After Simon's latest failure I wonder if there is something more to this than just electrickery. One 1125 can do 16000 with no failures, another xmiles on first stator then effectively 0 on the next one.

This is not about the stators themselves. I think stator/rotor clearance may be an issue? There's more to this than meets the eye.

The Ronin utilizes a new custom wound, high-efficiency stator that eliminates the overheating and burnout issues often reported on the original Buell 1125. In addition to the new stator, the rotor has also been modified to allow for effective oil cooling

We were keeping quiet about that Nige...

I couldnt find any engine spec on that, but
I'll Bet the 1190 has it sorted
Wonder if the parts will be workable, being that the casings are based around the Helicon?
My guess is that if they are, there will be an alternative fix along in a bit.
Guess everyone but me has seen this, but if any viewing hasn't:
http://www.twinmotorcycles.nl/movies.asp?cid=8&aid=265
and according to the commentary 'no traction control' unlike the bikes its up against
Sh@i@t a Brick

They've done all new wiring harnesses and connectors so it's debatable that what they have is a drop in replacement. Moreso, since they claim to have lowered the overall electrical load to be safe. And from how it reads, it doesn't appear they are selling anything, Ronin special part-wise, to anyone other than an actual Ronin owner. So anyone looking for a solution from them is still S.O.L.

Stator finally burnt out.In the interest of cost where is the best place to get a rewind in the UK,or is a new stator a better solution.Could a rewind be done to produce less power similar to the 2008 stator?Also interested in using a series VR but again where from,I can find none in the UK.This saga just goes on and on.

I had a drilled Rotor plus rewind and new Compufire Reg /Rec done at Black Bear when they were Buell friendly for £506 last year.
Twin Motorcycles in Holland may be your best bet these days or have a word with Maz I'm not sure what his take on these is.

With BB withdrawing Buell support, a PM to Jon64 may yield the firm local to BB that drills the rotor.

If anyone wants contact details just PM me. The drilled rotor seems to do the trick, I have yet to come across a failure on any machines fitted with one

Just seen an interesting lead on the badweather site.It seems that another way for oil cooling on an aprillia is to run a T-piece in the return oil pipe into the ignition cover thus spraying directly onto the stator.Could this very cost effective (95euro) be adapted for a Buell and would it allay fears other members of this site have about the current solutions.T12-tech is site advertising this method.
