2002 Sprint St Misfire

Hi everyone, new member. just bought a 2002 sprint st. Ran and pulled great on test ride. But now won't pull cleanly from below 4000 revs, stutters and misfires, but pulls fine above 4000 revs. Starts and pulls away as it should from cold, but do the same when hot and it stutters/misfires and stalls, if revs not kept above 4000. Any ideas anyone? Done the ECU reset procedure, which has made it worse! Thanks.

 

Hi Joe, thanks for you reply. Just bought the 955SPRINT, it's 2002, 27000 miles, last serviced 2018, but wasn't at a Triumph dealer, so big service not done, Battery's in good condition, cranks over and starts first time, on trickle charger since I,ve had it. Going in to CCM Motorcyclres in Stockton today, as having the big service on Wednesdat the 29th. Don't know if it's been stood, but it has been dropped at some point. Any ideas on possible cause / causes would be most welcome! Thanks again

 

Hi TD, Thank's for your reply, seems logical. Dropped it off now at CCM Stockton. So we'll see what it's like when I get it back. will post the results. Thanks again.

 

Thanks for your reply Freck, I'll let you know, when I get it back. Fingers crossed!

 

Many thanks Joe. Going to e;mail CCM, to make sure they check/adjust the shims.

Hi all, said I'd update a reply once I'd collected my 2002 Sprint ST from full service. Just collected it tonight. The good news is the new tyres, and rear shock are fitted, oil, plugs, filters and break service carried out. Unfortunately when I collected the bike and asked them if they'd checked/adjusted the valves, they said they don't do that, it needs to go to a Triumph Dealer. Funny they never said that when I enquired about them carrying out the big 24,000 mile service! Any how paid the £475.00 bill, rode away hoping the hot start pull away misfire/ stall problem would be solved, but unfortunately, when stopped for a short while, enquiring about EU number plates, the restart pull away stutter/ misfire/ stall problem was just the same. Rode straight back to the dealers, and asked them to take it for a spin, as the stalling problem was actually worse. The manager duly came out and tried to set off, but bogged down and stalled twice as I'd told them, only being able to pull away, after giving it loads of revs. All as I'd told them prior to dropping off my bike.
Well seems like, my plan of saving some money buy not using Triumph dealers has backfired! I'm going to ring A1 MOTO, or Triumph Newcastle, and see if they can give me a quote to do the valve clearance adjustment only. I'll let you know how I get on. Thanks all.

Hi T-D, I honestly don't believe they have done any checks at all. It just seems they 've done the normal routine stuff, oils,filters,ect. I did tell them to check for any fault codes, which would have brought up any faulty sensors. I also asked them on collection, and there reply was, no faults showed up. They were also told again,when I dropped the bike off to investigate the misfire, poor running pulling away with a hot engine ect. They obviously hadn't even taken it out for a test ride. Very unhappy with the quality of there service.
Thanks again T-D

Hi Freck, Thanks for your reply, you live and learn! They had a very convincing webb site. With service like that, they won't be around for long, and my normal Dealers Tillstone Motorcycles Stockton would not do it, as it's a Triumph. Just debating what to do next?

Hi all, Just an update on my 2002 sprint st. Rang CCM Motorcycles of Stockton, and said I'd give them an opportunity to try and get my bike running correctly, before I say or do anything further. Surprise surprise, they haven't called me! So they can expect a very poor review.
However on a brighter note, have rang Triumph Newcastle, and explained my predicament, and they couldn't have been more helpful. They have managed to squeeze me in this Wednesday, have said it could be the throttle bodies, but will do a full diagnostic check. They have also said they'll do all they can to get it running correctly for my Euro trip in a couple of weeks time. There you have it, the good and the bad dealers.
I tried to save some money, but have ended up spending more. Will let you know progress, when I collect from Triumph Newcastle.
