Increasing idle
 

Can it be done on a 749/999 safely

I'm trying to get my bike to tick over at around 2.5-3K for trackdays as it just parks itself into the slower corners but how can I do this?

I've got a PCIII also if that helps, but need to be able to switch between the high revs and normla tickover for when not on the track

what does this mean - "just parks itself into the slower corners" ???

:alien:

I've ahd a quick action throttle fitted on mine that has a button on it that can be used to take the freeplay out of the cable, I understand that this device can also be used to raise the revs at idle. Talk to Pro V Twins, of course I could be wrong.;)

I've got the same mod MM but that only works when you're warming the bike, as soon as you use the throttle it clicks back to the standard position

£200 from them - you could DIY for about £20!!!!

I know that this isnt strictly relevent but on safety grounds alone a single cable is just stupid!

The downsides of their mods are -

£200
you only end up with single cable operation - not very safe
their mod is completely overpriced and over engineered

I have a quick-action throttle that I fitted on my bike - £100 from Demon Tweaks - 1.5 hrs to fit from start to finish - works a treat.

But it doesnt help your idle issues - although I still dont know what you mean.

is it not the same as the 996 - 7mm spanner on the battery side of the bike?

Take throttle assembly apart and place a small bit of plastic where the fast idle button is on a 916/996 throttle that way you get the fast idle without it clicking off, thickness of plastic will determine idle speed.
I wonder if the housing without the fast idle button would drill and tap then you could use a screw and locknut to set the idle to where you wanted

7mm nut on right hand of injector bodies. I have already done this to mine, but be warned it takes a wee bit of getting used to at first as you don't have anything like the same engine braking.

I like skids idea. That would be ideal. Put a knurled knob on sort of like the lever adjuster on the Brembo radial master cylinders. Hmmmm...might just have to give that a go.

I'm hoping Yeti has taken the idea on board and will be knocking one out (pardon the pun) shortly ;)

Hum, might just have to think about that one.

Not that Felix will be gettin one cos he still owes me a workshop manual!!!!!! :lol:

make it harder to start too if you up the idle...have you tried starting from cold with an open throttle or fast idle on :puzzled::puzzled:

I've been running fast idel on the beast for a while and she always fires up first kick. Pretty certain the TPS will spot this and adjust the brain accordingly.

my sps has never been able to start with the idle pressed in, the engine doesnt turn over quick enough even with a fully charge battery

its a matter of catching it when it sounds like its going to start....also talking to MR today he said if I up the idle it may may it a bit more difficult to get going

Hm, tough one that, looks like I gonna have to design and build an adjustable one that can be brought into play when on the move.

an idea for ya . . .

having fitted longer bars to my 999s - I had to remove the "choke" (LOL) cable as it would NOT now reach where I moved the LH switchgear to.

Never use it anyway and all it does is pull the throttles slightly when activated.

Anyway, I have it cabletied underneath the ignition barrel for now - was thinking of buying a braze on gear selector off a push bike and attaching the cable to this so that if I needed to I could still pull the chokey!!!

The braze on lever (well its band on actually) fits exactly around the frame so I can mount it anywhere within reason - that might just do the job for you!

If you're suggesting a trade, I am game!:lol:

I was told that if you look carefully at the side of the airbox there is a rubber grommet, if you remove this and put a long screwdriver in you can adjust the idle screw.

I have looked in the past and there is a rubber grommet but I have never looked to see if it works ?

So,whats the benefit of this "fast idle ",then,when,on track,eh ????

:puzzled:

It makes going aroung the slow hairpins smoother, as you can ride round on closed throttle.

I am a luddite - I prefer to do it manually. Here's a thought for some of you who might consider messing around with shims, stops or any other heath robinson mods etc. If you have not fully tested mod and it goes wrong then you may get yourself into a shed load of bother. Believe me - a throttle stuck wide open is pretty terrifying and you may not have the presence of mind or time to reach for the kill switch.

Go to an expert if you must do it - like John Hackett.

May be I have missed something (sorry in advance) but couldn't you just keep the fast idle open a bit while you are on the track?

Best tell that to all the 998r owners then cos its the same engine same throttle bodies just turned around, and.....a single cable operation!
