Early 1050 Stators

[Avi8or]

So I suspect my 2nd stator has taken a dive.
This is an email I sent to Electrex World http://www.electrexworld.co.uk/ and their reply:

The Triumph Speed Triple 1050 years 2005-2007 seem to suffer from a defect.
Possibly due to insuffient cooling their generators/stators seem to overheat and eventually burn out/short their windings.
Your G75 generator which fits this bike seems to suffer from this same problem as the OEM item.
I was wondering if it would be possible for you to produce a 'special' G75 generator with high temperature windings or any other
configuration you deem neccesary in order to address this ongoing shortcoming.
If you can accomodate I would be most happy to order one even at a higher cost than your stock item
and would definately advise my collegues on the Triumph forum that such an item exists.


And the reply.......


Sorry no quick fix for this problem. For the 1050 power output of the stator was increased without addressing the consequent increase in stator temperature Triumph could probably have directed an oil feed to it which would help with cooling.

We actually don’t get many returns compared to the no of sales but there is always room for improvement so with our next batch due to be wound next week the winding configuration will be adjusted to reduce the running temp.

sounds like a good company if they do end up putting their money where their mouth is.

Good stuff Jimbo,looks like your email had an effect.
When my last stator from Electrex world fried,i had 1 week left on warranty.
They shipped me a new one without wanting a return or photographs of the burnt one.
Whilst i was waiting on the replacement to turn up,i had my original Triumph one rewound down Chewie's way.
Talk about a difference in windings ,i now have a spare.

Well I been doin some readin yesterday and the overhating problem seems to be more regulator than anything else.
Seems that the normal R/R's both the OEM and the Shendingen are of the shunt type, basically they short out the stators
windings at highish rpm's when max voltage is reached, obviously putting a high load on the stator windings and hence the overheating.
The solution seems to be a series regulator which does not do this, hence the stator's windings remain cooler.

Compufire 55402 seems to be the RR most suitable as a replacement.

Anybody over here using one of these?

What the hell decided to order the Compufire 55402, seein I just put in a new battery and stator........maybe this stator, the third one will last a bit longer.
Will let you know how it goes.

The copper wire looks thicker and looks like there is more of it,f#*face.

In which stator is the wire thicker, ya dumb c@#t?

It is a good company.

1 They took heed of my suggestion
2 My new order was despatched and delivered within a couple of days from the UK
3 They replaced Bucket's stator under guarantee without any hassle whatsoever
4 My mech uses their products exclusively to replace fubar'd OEM items with excellent results.

Well my latest take on electrics is this:

If your R/R has a habit of getting knackered then go for a Shendingen (like Triumph did for their Street Triple which had a habit of chewing up the R/R's)

If your stator keeps getting fried then go for a series R/R like the Compufire (awaiting confirmation of this, a few years down the line)

Also the OEM plug on the stator IS a weak point. Best to use a heavy duty plug and socket or solder the wires to those going into the R/R.
