Jerky on closed Throttle

[Mike40]

Rode my new purchase back from Cornwall on Saturday and I have fallen in love with my GSX1400.......

However I am not sure if she is running right or if this is just what all these do? When approaching a junction or traffic with a closed throttle it is really jerky, sort of surging on and off and is really difficult to ride smoothly in slow traffic where you are opening and then closing the throttle at slow speed.

There is no misfiring and is smooth on any throttle opening, just not closed??

Any suggestions as it is a long ride back to the dealer in Cornwall.........

Mine was a bit like that on the first trip home. I bought it privately and it turned out that the previous owner had a fairly lax attitude to maintenance, so the chain was really slack. Tightening that up improved things no end. Worth a quick look (although to be fair a dealer should have sorted all that).

Throttle cable adjustment can make quite a difference to how they ride at low speed.
Enjoy your new bike

Also - don't forget 1402cc is a lot, and torque starts almost from idle. So bike react on even slight change of throttle. Especially on lover gears.

It'll be chain slack, throttle cable slack, TPS adjustment or dirty plugs.

Also the PAIRS system is reputed to make it a bit jerky at small throttle openings, especially with aftermarket exhausts. Opinions vary on whether disabling it makes any difference. I haven't touched mine because I like the burbling sound that it makes. Childish I know, but true.

PAIR removed on mine. Beowulf slightly shortened end can. 5 Degree ignition advance by slotting backplate...Mine can be jerky at low speeds with small throttle opening..I've just got used to it over time.

And learn to play with clutch more then on 600cc bike

Hi Mike40 & welcome along.  As the guys have said above, it'll be nothing serious, just a wee bit of tweaking (not twerking) required.

have written to many new owners how to make 14 perfect. maybe we need a list/instruction sheet written up. im not clever enough to write it but know what are the adjustments required. sort of a bike intro , things you must do. if anyone wants, ill list it up for someone to make it a sticky. just want them running perfectly, makes everyone happy. small changes , but great results. mine was supposedly all serviced/set up by dealer when i got it. wrong. so many things wrong. an intro sheet i think a great idea. just trying to help.

That's a good idea Grog.  Yep, all the little things to 'fine tune' & 'get it running right'   Sounds like it's got Sir David Barmy written all over it . . .

[grog]

thanks Col. ill write up reqs if someone, Barmy, wants to make it make sense. mine as smooth as a cafe latte, nothing to do with clutch or engine size. they just need a few tweeks. smooth as a Kilcenny from a cold can, much better description.

Wot if ya don't like dark beers though?

Just needs a Barmy write up with links to Barmy's other writeups. Simples.
