my zx12r stutter

Hi everyone,just joined from across the pond in England so hello.Ive recently bought a 2000 a1 with just 24500 mls on her,in fantastic condition with a straight bar conversion,engine and exhaust standard.After 3 weeks of ownership and approx 300mls,the bike has developed a bad stutter or misfire between idle and 2000 rpm.If left in a high gear down to 30 mph and then throttle on it stutters,after 2000rpm she revs cleanly and goes like starship enterprise.At the moment here in England its winter with the dreaded salt on the roads,so after every ride i painstakingly wash her down and apply anti-salt spray.Could the misfire be down to damp in the coil sticks or anywhere else.This is my 3rd zx12r,and the previous ones never behaved like this.Any help would be gratefully accepted,cheers Graham.

hi and welcome to the forum, not sure about your problem but you could start with setting /checking your TPS, do you have a manual ? it will come in handy, doubt its damp coils now have you done/checked if done the regulator oil wicking mod cut off the regulator connector and solder the wires heat shrink and your good to go will give you something to do while freezing your nuts off, here is a link to Dave's website for zx12r tuning and TPS setting [URL="http://www.drpmds.pwp.blueyonder.co.uk good luck enjoy these bikes don't really like low revs under 2500rpm worse if aftermarket headers fitted Craig

if anything goes wrong check the battery

Thanks for your reply Craig,yes i do have the manual.When i got the bike off this chap who had owned it for 6 yrs i got a few spares including coil sticks which got me thinking about them.The stuttering got so bad it felt like the chain was trying to jump the gearbox sprocket,so on inspection ive changed the chain and sprockets and retained standard gearing.

Would start with the easy stuff and pull the plugs and check them out first, cannot see damp getting down there as they are well buried and sealed.....should be a plastic tray and rubber mat above coils.

Sounds like an issue my brother's ZX12 had. Put new spark plugs in and it sorted it.

Someone else from Wakefield, theres BikerX also in wakefield and me in Altofts.

I have an adaptor for tweaking the TPS, only takes a couple of minutes.

For Tech Questions Bike Model letters are more useful than saying the year, for uk owners anyway, as registration year is not always year of manufacturer model.

Greetings from Wakefield on Sea..... TPS tweak via Ninja Yorkie offer will be quicker than changing the plugs, that's for sure ;-) 'Tis the season to fettle your bike....
