TLs Surging below 3,000rpm

[Haggis]

I know its probably been asked a hundred times but is this something that can be dialled out easily enough. i mean its not too bad just when trying to cruise along in town below 3,500rpm it can sometimes be a bit 'lumpy'

Any help would be appreciated.

Is it surging on it's own or are you talking about snatchy throttle response?

[Ogre1231]

my old TLS did that like a mo fo. Could be bad mapping, or could be in need of a tre.

[Jokertlr]

It could very well be TPS too.

[SWEET-TL1000R]

MY TLS did that as well. They're just not supposed to run at that low of RPM's with the clutch out. You're basically loading the plugs(just a guess). I would try to keep the rpm's a bit over 4,000

TPS!!!!!!!!!!! I cannot stress enough the importance of this adjustment! It made my tiller 100% more tolerable in the lower RPM's. Do a forum search and you will find a buttload of info on how to do it.

I cruise the city in 1st gear.

Makes everyone (except the Blue) happy.

Sweet (OH sooo sweet!!!) musik for the pedestrians, the cages hear you, the bike answers quik - you are ALWAYS ready for a quick PowerWheelie.

Perfect.
(OK, sometimes I shift to second, but mostly only i I sees dogs or so att the catwalk....)

My TLR was the same way until I sync'd the throttle bodies and set the TPS.

Now, NO MORE SURGING!

Yeah I got an idea, drop it down a gear and twist the throttle, this bike aint no cruiser. Take it out and give it what it needs

TPS, TB sync.

And what got rid of the last of mine was a TRE. The results of a TRE seem to affect different bikes in different ways, that is from no improvement to a little improvement to heaps of inmprovement.

As said above, setting the TPS and synching the throttle bodies, along with proper mapping of the FI, will go a long way toward easing the low rpm snatchies.

The reality is, though, that you are astride a bike with only 2 4" high compression pistons running well under a 3" stroke. That big old slug doesn't like to run that slow and only tolerates it when everything is dialed in. Try riding an open class single cylinder thumper at low rpm. They can really buck.

It can be minimized, but the fact remains, that is the nature of these big piston and comparatively (to a Harley, anyway) light flywheeled beasts.

Dial that tach up to "7". Oh ya

Thanks for all the help. I have been tending to drop into 1st and run around 4,000 in town and its fine. I will maybe spend a bit of time setting things up as well. But I think you are all right in saying that this thing is not a cruiser and revs are the key to happiness.

Tools Required

Do I require any special tools to adjust the TPS ? I read the instructions after doing a search and am not sure
