I was just wondering if this is normal. Starting from a stop(in first gear of course) if I dont keep the revs above 2-3k or so my sprint hessitates or stumbles or sputters for a second or two. This makes for a very jerky start until the engine spools up and takes off. I was wondering if this is normal and I just need to keep the revs up a little higher when starting or if my machine is telling me something?(ie. tune up or valve adjustment or something else?) I am a total rookie with bikes so any help would be appreciated.

My 05 Sprint does this same thing. When I asked the dealer about it I got the standard "Triumph Dealer response #1", "That's normal for these bikes". Standard response #1 was then followed by Standard response #2, "There's nothing we can do about it". I would guess that they are running way too lean as mine also pops through the muffler on deceleration and the throttle is extremely sensitive. Probably will need the aftermarket to fix it.

trafficfixer, you didn't say what year your bike is.

If it's a 99-04 there is a suggestion I could say but I'm not sure at this time about the '05-06s.

How much of a "total rookie" are you? How long have you been riding?

trafficfixr · 09-12-2005

How much of a rookie am I ??? About 400 miles total bike experience rookie. all of which came since friday. And my Sprint ST is a 2002. I am just feeling it all out. Learned today that baggy clothing that flaps around in the wind is a pain in the ass and going over a 2 mile bridge over the great south bay with a 20-25 mph crosswind took some extra focus. But all is going very well, i cant tell you how many people have complimented my bike at stoplights in the last 4 days.

A bit of a luffing just off idle usually can be traced to a lean condition, which these engines are known for. You might want to have the dealer check that the proper map is loaded in first.

I'd sooner think the problem rests in your clutch release timing. Lets not jump to conclusions about the bike until you've got a little more seat time.

Good luck, keep practicing, and keep us updated to your progress.

True. didn't think of this angle.

On my '01 I can actually dump the clutch a little quicker without giving it any gas at all, then if I'm giving a little shot of throttle. The bike seems to like chugging away with nice easy throttle for the first few feet, then I can "throttle away". Gas w clutch right away seems to choke it.... A new map last fall really didn't change this trait... No real solution from the dealer...I've just learned to live with it. Clutch first then gas away after I've moved a couple of yards...

Thanks for the help guys. As for me letting out the clutch improperly, that may be true. But even if I let the bike go below 2500 or so rpms in any gear it sputters and bucks until the revs come up. Cant blame that on my poor clutchmanship. :???: I was just wondering if this is a normal condition or if the bike should pull smoothly from that low of a rpm? I am willing to keep the revs up if that is what is necessary I just want to know if thats how its supposed to run. Thanks again.
