B1 idle speed

[1-600-matt]

So this is my trackbike and I want to turn the idle speed up a bit to try and stop it skipping the back wheel about when downshifting. Do I need to adjust the throttle position sensor?

I found feathering the clutch helped more.

Will blipping the throttle help so you kind of match the engine revs?

[Alzo]

Leave the throttle position sensor well alone. The idle is adjustable at the engine end of the throttle cable if needed. But it's not a tactic I would employ.

There is an idle adjuster knob above the front sprocket on my b1 iirc

Yeah there is an idle adjuster so changing it is easy. On my k5 fact if I turned the idle up once it went into gear the revs would drop and the throttle position sensor needed to be zero'd. There was a display in dealer mode so you could find the set point. It would knock the powercommander out if the throttle position sensor wasn't correctly zero'd. I will maybe leave it alone and try to learn how to blip the throttle and feather the clutch a bit more. Cheers anyhow all.

If you are barreling into corners at breakneck speed feathering a clutch is the last thing you want to be doing imho...blipping the throttle to match the speed and chosen gear is the way to go.

Does the B1 have a slipper clutch? Maybe leave knocking it down the gears a bit later. I had one and didnt have an issue with it, but i blipped on downshifts

Raising the idle speed to around 2 / 2.5k rpm is a common adjustment for track riding.

What do you think slipper clutches are doing then?

No it doesn't.  The ZX6RR did but they are rare as.

[Gobert]

I'm not 100% sure but Sigma might have started selling slipper clutches for B1/2's?

[Millhouse]

Yes, but they're £700 plus vat

Slipping without any thought or input from the rider thus freeing you concentrate on braking and cornering...to add feathering a clutch in to that mix is asking for trouble in my opinion...and it is only my opinion...I know I would never have done it on road or track...throttle blipping worked for me...I wasn't Rossi on track...but I wasn't a tail end Charlie either.

Only place I've tried it was  the back straight at snett, big braking, blipping and the rear was bouncing all over the place.

Add a little hint of clutch slip and all was peachy setting up for the corner.
