Aww, I was flicking through the Haynes trying to make "978" work somehow :P

Well, the answer is finally here ^^

Isn't the purpose of a regulator to well... regulate? This is likely to be utter crap but would it not just work to make sure that there aren't any spikes in voltage / amperage? So that a steady stream of power is provided...

 :) .....well being the electrical genius as i am? :b ....i would say it regulates the supply of electricity" to/from the pickup coil and supplies the engine with the given amount it needs to stop the fucker ....STUTTERING...at high rpm"S.....technicaly speaking that is? 8)

Apparently yes, the regulator is used to ensure that there is a constant load of 14.4 Vdc (typical - could be different on our bikes, but unlikely) to the battery

Ok, so I've been flicking through some internet articles and here is what is confusing;

The charging system, as far as I am aware, is separate from the electronics in that it connects to the battery THEN the battery powers everything else - in theory. So, a fault with the charging system shouldn't cause a problem with the electronics on the bike UNTIL the battery is drained. If so, then why would the regulator cause a problem...

However, if this is to with load across the battery, then its ignorant to think that the charging system is entirely separate. It provides a Vdc across the terminals of 14.4 - so if it is faulty it will (in most cases) cause this value to drop but it shouldn't go lower than say the 12 Vdc of the battery itself (more like 12.6+ on a fully charged battery) until the battery is drained. This drop could be enough to cause the spark to become weak.

Now, as you crank open the throttle, you are pulling more air and fuel into the combustion chamber, right? So with more fuel saturation in the vapour, you need a stronger spark... if the spark is weak then you run the risk of a misfire... or stutter?

I assume this is what was happening?

Edit: Ooohh another thought - the stutter clears up at higher RPM right (at least for others) - could the increased heat from the larger combustions begin to counteract the weak spark a bit so that you avoid a misfire?

Must admit to being a bit puzzled by this as well.
Regulator rectifiers can fail in two ways: either delivering no electricity to the battery, in which case the sparks would have held up until the battery voltage decreases, but you'd spot all the usual symptoms of a dead battery in that case. Alternatively they can stop regulating, which means the full output of the generator is forced into the battery causing the voltage to rise. (My brother had an Audi with that problem... he liked the extra-bright headlights, but it killed the aftermarket transistorised ignition unit!)
Unless you also had a poor connection to the battery it's hard to see how either condition would cause a stutter, and I'd have thought you'd have also noticed the lights changing in brightness.

Could be a fault with the unit sending too much to the earth effectively lowering the voltage across the battery? I don't think its necessarily as black & white as "it works" or "it doesn't work" - probably a grey area where its only partially working, or not working to full capacity / spec - this would then allow for the conditions observed...

When everything you know to be true can't explain it, it's time to reconsider those "absolutes" ;)

Yes, fair enough... it may not be an all or nothing fault and would presumably be intermittent to boot, but the problem remains that the battery is very good at soaking up or delivering brief surges of power. If the regulator decides for a few seconds that it should be delivering 6v instead of 14 it has the full output capability of the battery to contend with. Sure, it can drag the voltage down eventually, but I'd expect the lights to go dim before the sparks got weak.

great repiles there chaps,iam still running the replacement pick-up coil as the wiring on the old one was damaged and brittle,so iam thinking that both items were to blame ....need to do my homework on this so i can keep up  :o

Regarding the regulator - Totally agree with you Fazerider, be good to double check by putting the original back on to see if fault comes back, as far as I am concerned the bike does not even need one to run properly, well as long as there is juice in the battery.

Can I just ask, have you taken the bike for a test ride with the new regulator fitted and if so, has your stutter gone? Also, how much was the new regulator? Might be ordering one tonight to see if it fixes my stutter too!

So, 17 months later, you finally fixed the stutter.

yes ..been on a short test ride and theres a massive improvement,very smooth from 2000 all the way upto the red line......your do well to get a secondhand regulator for £20..ebay,breaker etc....i have a spares bike so stole it off that  :)
