Right well it wont even turn over fully on a car battery !!, It turns very slowly albeit without any clicks but no where near fast enough.
So if a fully charged car battery isnt enough, then no motorcycle battery would be. So now I'm thinking that theres something wrong with the engine itself , maybe its partially seized or the valves are bent, something that has caused such a rise in compression that it cannot turn over anymore.

bent valves would lower the compression so i don't think it's that.
Take out the new batt and put the old one back in and try again. If it has a duff cell it may pull the whole circuit amps down. It was turning at a reasonable speed with the old batt so i suspect the new batt may be an issue.

Well I have tried to directly jump it from a running car engine held at 2000 rpm.....nothing it turns over with lots of noises but thats it , it doesnt fire at all or even look like its gonna fire.

I hear what your saying Spoonz but i still think Aprilia could do more about the starting issue.
Why do we have to fork out for a high amp battery, more powerful solenoid, better plugs ???, Why dont they come as standard on these bikes
Take a look at the **** side stand they fit, Aprilia know its a problem cos the where getting law suits from all the yanks when there bike fell over, hence the US bike have a better stand. Im guessing they know of the starting issues but still do fook all about it !!!

Yeah, my bro bought an '04 Factory from the local auction earlier in the year. Only had the power to give a click, so we put the jump leads on to my car battery - engine not started and the bike fired straight up.
Worth a go mate.
If a battery is gonna **** up, it's when the cold weather appears.
I agree with Spoonz as in it's the engine configuration not the country of Origin of the RSV. Bit like a Diesel car needing more cranking power in a way.
Think of all the engine braking on overrun on a V-Twin too.
It's a shame that one of the very things that make the bike have such character and attract you, pisses you off in another way - getting it started.
One of the Yank threads started mentioning changing starter motors?
Spoonz - sorry to be a bit thick, but how does the higher rating of the relay help, does it feed the starter motor more current?

sidestand issue was a problem but generally fixed in 2000/2001 with a metal pin design instead of plastic. Usa still have a different stand to uk even today but it has nothing to do with faults.
Aprilia however are not immune from **** ups and i don't dispute that.
We can however qoute cases all day. there is an answer for every answer so to speak on both sides of the problem. I am making the point that starting problems on a twin are not unique to Aprilia and not always due to an oem part of the bike.
Kiwi we are making big jumps in symptoms without knowing what you did in between.
are you now saying it turns over at correct speed, what changed from before ? are you back to the orginal batt.
If cranking speed is ok is fuel pump priming ok before you hit the starter. Can you pop a plug and make sure it sparks when cranking etc.
Having tried to start it with a less than 100% batt you may have flooded it. close fast idle and give it a shortish crank with throttle held wide open. but get ready to shut it quick if it catches.

1. Original Battery , pump primes, turns over with noises , dash resets, no fire
2. New Battery, pump primes ,just clicks, no turn over
3. Car Battery on is own, pump primes, hardly turns over
4. Car Battery, pump primes, turns over with noises, after a few seconds dash resets no fire.
Not knowing what sort of speed these things should turn over at I would say it sounds like its turning over medium slow

Should add all attempts have been with air box off...ie throttle bodies open to the atmosphere.

Very well put mate,
Im not trying to be some kinda Aprilia basher here, its just really annoying. Aprilia must know that the starting is a weak point on these bikes and with a bigger battery, better solenoid etc it would make our lives/pockets alot easier.
Cheers,
Ritch
tried starting with full throttle and no fast idle , impressive pops and bangs and a throttle body flame out .......but it still didn't fire.

Petrol + Match = Early RSV bonfire
Ignore the above thought mate, wrap her up and wait for Amb, a new pair of eyes and ears might be just what you need. walk away from the bike and have a brew :thumbup

Be careful dude,
if she is struggling to start you could end up knackering the sprag clutch
,As ST say, take a break and have a brew !!!
Well if she's still not running after amb's visit then its going to have a nasty accident. A very nasty accident indeed.

without hearing your bike it's impossible to say if it's turning over fast enough.
I'm tempted to say wait for amb at the weekend. If he doesn't mind you can try his batt which you know is starting his bike ok.
flame in the exhaust and back through the Tb's is a sign you have unburnt fuel which points to an ignition issue. That said if the dash is resetting still and a slowish turnover the bike may still be not getting enough juice.
why that might be i'm not sure and there are too many variables we can't see or test remotely.
Just a thought though. didn't move or fit the tip over switch upside down when you took the batt off did you ?

if it's in the right way round then chances are it's not that. it was just a though that you might have knocked it off. You could give it a rattle just to make sure it's not stuck.
it rattles quite nicely
have just tried to start it with the upper front spark plug out and held to the chassis, nice bright blue spark....and a nice flame out of the plug hole.

Ooh, watch them plugs near the open hole!
This is a confusing saga!
Fuel present & pump working, turning over - with help, spark present... :dunno
