Like the look of it and had a hankering to do this are two other valid reasons for doing it.
Willy, I applaud you for taking the path least travelled and doing your own thing. Keep it up, your an inspiration

well boys n girls this is an excersise in freeing HP to the back wheel........the folk law is the altinator robs around 5 hp ..........cranking will be brisker as well ,ultimatly were looking for far faster engine spin up time ....and healthy tourque curve lower in the RPM range say from 3000-6000 ,bear in mind that the nine engine is being treated as if it were two 500 goldies turned into a v twin, the numbers are very close ,von has had a GOOD look around the nine engine ,we of course have no real idea what what we will end up with ....it MAY not be startling .......but were preety sure ill get what im looking for ........which is an engine performs very well between 3000 and 6000 RPM ,bear in mind also that bearing life is a square law ....as the the revs rise bearing life is DRASTICALLY reduced hench a say 6000 RPM sealing ...ooa maz feel free to build one along with us your way .we can do battle ont dyno .

Ok quick translation from willybuell to English
Standard Buell alternator magnets very strong, requiring a lot of energy to turn shaft .
Its hoped by fitting a different type of alternator to redirect as much available power produced by the engine to the back wheel = fun times

then lose it all by having to have his leg stuck out at right angles like a massive air brake and add to that it'll look shitter than shit.

Lose 2 stone willy that'd be like finding another 10hp.


Andy

I take it that the new alternator is significantly more efficient????

I dunno but I assume that because the new alternator is now not a direct drive off the crank you will have power losses in the belt and pulleys...Isn't an alternator's 'resistance to turning' proportional to load that's placed on it anyway?

I'm struggling to see the efficiency gains with what looks like a relatively heavy, non direct drive alternator....

Andy. You have such a way with words

You can gain another couple of horses by eating loads of baked beans

ive lost two stone in past 18 months as for shitter than shit fair comment andy ,im sure like the regulars on here over the past 4 years have seen its my way ,wot i want and thaaats it xx

The problem with nearly all motorcycle alternator's is that they use a shunt regulator which means that the alternators output is the same whether you are using 1 watt or 100 watt, you just dump the excess 99watt down to earth through the regulator . This is one of the reasons why bikes like the 1125 amongst many others have problems with overheating alternator windings and why a lot of race bikes use low output alternators.

OOOOOOOOO KK food for thought here and a bit o work possably,we will see deff going adjustable push rods

missed a critical point here kev.....tut tut permanant magnet alternators are the problem not the regulators tut tut ,permanant magnet alterrnators are max output regardless and the problem with the 1125 is .....the windings untill the oil jet mod ......were piss poorly cooled and kept at a working temp were they didnt burn out perhaphs this is why on jap bikes these days needing high output from alternators they fit NON PERMANANT mangnet altanators behind the fuking barrels

OOOOO KK this is the kind o set up that will drive my altarnator

OOO KK the pink dots might get drilled n tapped so we can adjust the clearences in this area ....this would mean fixed lenth push rods ....not adjustable ones....food for thought .
