02 Curvy stalls at low revs

also this may sound silly but tighten the battry conectors/cables under the seat

Sorry Dave, I didn't really couldn't understand what to do for your test?

I have a reg/rec problem on one of my SVs. I know it is this, as..

I use only one battery between the two bikes. On my black SV(the suspected naffed reg/rec) when I rev it, the headlights dim 'significantly'. When I say significantly, its not slightly, like my yellow SV...its huge and very noticeable. When I noticed this one morning after finishing work, the day after the battery was as flat as a fart. I charged it up, and it has worked absolutely fine on the yellow SV. I can bet my bottom dollar the black one would discharge the battery pretty darn quick.


Although, to add.....the revs DO NOT go all over the place as you describe

Sorting choke cables is a barstwerd. It involves taking fairings off, tank off, air box off...and usually plenty of swearing and cursing, and skimmed knuckles. Its been a long time since I have seen this performed on either of my bikes. What usually happens with this problem is very very poor running. It struggles very much to give much power.

This is true, but they need time to warm up. I find that without some fuel treatment or when using "normal" unleaded fuel, the first 10 mins on a cold morning can cause my bike to cut out due to carb icing, until the heaters are coming into play. The worst time was riding on a very cold, misty night about 2 years ago, my bike wasn't playing ball for 15-20 minutes! I eventually stopped at a petrol station and let any heat in the engine warm the carbs, before setting off. Once up to temp, the bike ran perfect for all of 100 miles around the motorway. In the pitch black. In the freezing cold. in the thick fog.

Never again.

As for the erractic idle: the choke may well move fine, but you only need a choke plunger to be ever so slightly not closed to cause high idling. On my bike, when I had choke problems, it was the front one what was not closing properly due to a small amount of corrosion.

Further more, getting, and keeping, the carbs balanced helps with good running

But.. but... I had it checked a few weeks ago, and they said the charge rate both with headlights and without were just what they should be?

Have you run an extra earth?
The earth thats stuck to the rear cylinder sometimes corrodes and causes issues. Try running an extra one.
Also dunno if this is possible, and someone with more technical brain may correct me, have you had the coils checked.

I've had enough electrical gremlins to shake a stick at with my yellow SV, so I can throw a whole load of suggestions your way to look for, which I have had with mine.

Just to clarify------You had this problem and got a new battery,and you later found the reg was faulty?If you ran the bike with a new battery and a reg that was overcharging you may have cooked the new battery.This could account for it not holding a charge now.Just a thought.

Diz, can you get me a picture of the exact location of this earth?!

Firstly dont use any other super unleaded other than shell V-Power, as the others are all rubbish. Get a bottle of Silkolene Pro-FST - its anti freeze for fuel. I would suggest replacing the battery as its cold and they get weak in the cold.

And stripping and cleaning the carbs and then balancing them properly

Let us how that goes

lol, well its very err not noticeable its hidden well! oh and its very dark outside, and I never took one when this was looked at. I'm sure someone who reads this thread who knows where it is will no doubt post one eventually.

Never had to use any of that apart from normal unleaded...and its bleddy grim oop ere in winter...specially at 5am! Heard a few folk go on about this Pro-FST stuff, but is it really necessary? Can't see how, and I've had mine out every winter.
