2000rpm idle

[blowme]

I don't know about anyone else but I'm fed up with hearing problems with poor idle, stalling, fast idle etc. I have seen a lot of R3's since fitting superchargers and one thing that keeps rearing its ugly head is this problem. My last customers bike was fitted with our s/charger and after 500 miles or so it decides to go to a 2000 rpm idle. I had the bike back, played around with it, resetting codes etc and got it back to a 750rpm idle but it wouldn't come up to the 820 rpm programmed. I went out for a ride everything was great until I re fueled. I restarted the bike and get an instant 2000rpm idle. I struggled back to the shop. I could see that the idle control servo had maxed out. I changed the servo and the new one maxed out. Time for drastic action. I unscrewed the servo and zip tied it out the way, adjusted the idle manually to 800rpm. The bike now runs great. It idles at about 650 until it warms up but I have instant throttle response and no hang up of any description on closed throttle. I've never had a bike with a throttle servo before and I can't see why we need one now.
I hope to talk to a techy at Triumph tomorrow to ask what the ecu is looking for to keep a constant idle, for sure its not doing a very good job.

Nice one, let us know how you go on.....
Would be good to put this one to bed.... permanently 8)

Why dont they touch the TPS on the latest recall. i thought that was for the idle prob :?:

ECUs / injection systems are an overcomplicated piece of £hit at the best of times.
Gimme carbs any day...........

O if it were so simple :!:

Now you got me picturing three big AMAL GP carbs with a remote float. :lol: :lol: :lol: Gasoline dribbling from the float and spitting back out of the carbs at idle. Me sitting astride the bike, reaching over with my right hand to tickle the remote float bowl before startup!! Wearing a fire extinguisher strapped to my right leg and a spare on my back for a back up. :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

it's frightening to think I can remember Amal carbs and remotes. Had a pair on a TZ250 A1 back in the 70's. Funny how I can remember that yet I can't remember what was said to me 3 minutes ago!

On a serious note this is a 3 month old bike. yet its been the worse of any.

Sad to think that with all of our new technology we are still without idle! Many years ago I was struggling with my Commando's idle. The permanent fix came with the Boyer electronic ignition. Turns out the main problem was the mechanical auto advance mechanism hanging up and rarely returning to the same place twice. This combined with rapidly wearing Amal carbs gave owners nightmares at traffic lights and stop signs...........fast forward 35 years..............
Having said that I did see a post on another R3 site where the owner had a problem with a sticking throttle shaft which caused the butterflies to occasionally hang open slightly giving a 2000 rpm idle. Something to check maybe. BTW my bike has approx 34,000kms on it and I've never had an idle problem
