You can alway fit a YTZ14SBS battery. This gives much more cold start cranking amps compared to a YTX14BS. Might be worth a shout if you're still having starting probs. I believe you need to do a small mod to make it fit correctly.
Badger i think knows more on this.
bit of an update. No scum bags pinched it so I had a look at it. The negative lead was working loose tightened it up and the bike fired up straight away.
Knocked it off and fired it up again and the battery had lost a lot of its oomph and wouldn't start it.
So i'm not really sure if I fixed it. The problem is if it doesn't start 1st prod their isn't enought juice in the battery to get it going.]
I left it off the optimate last night and have just started it with my multimeter taking readings.
It was 12.6 volts before turning the ignition on the battery dropped to 11.8 volts
1st go at starting dropped the battery down to 10v whilst cranking, It didn't start.
Battery recovered with the ignition off to 12.4 volts had another prod at the starter and it dropped to 9 volts whilst cranking
Knocked the ignition off and the battery recovered to 12.2 volts. The battery dropped to 8 volts just as the bike fired but didn't reset the clocks.
The bike then charged at 13.3 volts.
It must be a poor battery, even though its only a few months old. I'll change the starter relay too whilst im at it and give all conections a good clean.
Thanks for all your help
Have you tried changing the spark plug leads/plugs?
Also name the dealers who cannot fix it!
Someone else may have more info on the dealer............
First thing I did. Checked the plugs to make sure both plugs were working. One wasn't so I checked both plugs in the working cylinderto make sure both plugs were ok. I did the same with the leads to count them out too. This led me back to the coil pack. Following the diagrams found that the fuel relay must be working because the bike would fire up on one.
J&L ordered a new set of coils. They fitted them and it didn't work. They didn't know how to use thier diagnostics machine and was blaming the fuel injection system as it was showing open loop (as it does when the engine is not running and you are on Map 2). They also got scared by the powercommander as 4 plug and play connectors was too much for them to understand. They lied on the Warranty claim saying the bike was fixed otherwise they would get charged for the coil pack they thought wasn't at fault.
I then took it to another Aprilia dealer who diagnosed the problem but is struggling with Aprilia to accept the warranty claim.
Sorry for Hi Jacking the topic but I guess it still relates to the title "piece of **** Italian *****". lol
i have just read that a ytx14bs doesn't fit an 04 onwards bike
is this true?
as i'd love to upgrade
Gaz, i will do a post later on the battery size and fitment, also the brown connector is better hardwired, 13.8 to 14 volt should be the charging voltage
we shouldn't have to re-wire this and uprate that and change this etc
we pay a lot of dollar for something that should work
Mine's going - mind made up as soon as its out of the garage with brand new sprag clutch its up for sale
yeah i know i've spent nearly 2 grand on this bike putting it right, but its proper skint me - and i cannot afford it anymore - well sick
watch out for it if you like - when its sorted it'll be fleabay for 4 grand
