Deceleration Jitters?

[Commuta_Busa]

thanks for the additional info, it may be drive train related even though you're feeling it in the grips.

Just letting go of the throttle.
Coasting or coasting down to slow down without using the brake.

It is more present 40mph or below.

roads are fine.

Accelerating normally it goes away.

I'll get someone locally to ride the bike for second opinion.

The bike will buck a bit if you are in too high a gear and too low idle speed.
Try downshifting when the revs get to 2500 or so.

any rubbing noise,like a rotor hittng the brake caliper?

almost sounds as if your tire isnt balanced properly

 

[Over_Easy]

Has the triple tree been switched out?

I was gonna say this, but I figured it was too obvious

 

[Djxtrodinaire]

What is the recommended RPM for what speed?

again new to the Gen 2 so I still need to learn the bike

thanks for everyone's Input.

What part of MD do you live? I'm real close to Hagerstown and could take a look at and see if it acts like my K8.

 

[mike1180]

I never let my gen 1 go below 2500 when I am driving.
It runs better there and won't carbon up as much.
The noise is also helpful to the cagers when in traffic.

This is exactly what mine was doing due to a cupped front tire.

hmm
gonna get a bike stand and see if the tire has some flat spot

 

[Busa1166]

Definitely doesn't sound normal. Warped rotor??? Definetly need to hunt down that problem

 

[dalynchmob4]

no jitters here bro.... could be a bad ft tire maybe....

 

[semperfi]

That low pressure could have caused tire cupping. I run 42/42 in my 08.

I checked the pressure it was around 32/34

I added more to 40/40 its a lot better this morning, But I can still feel the front jitter when decelerating. I need to adjust the front fork damping, it feels a little bit soft.

 

[StromBusa]

"jittery" almost indicates a light feel to the front. Don't know what to say. New bike for you, get it checked out before something bad happens. I noticed the slipper clutch adds some subtle inputs on decel (while downshifting). The cups on teh tire wont be flat spots they will be the whole way around.

 

[ResidentEvil]

Its the SLIPPER CLUTCH you know that feeling when your below 40mph and your slowing down .......its the slipper........ it feels weird theres nothing wrong with your bike.

 

[ta-kid]

You said you found low pressure in the tires>Too late the front has proably already cupped and proably will take a 1000K to wear them smooth again if you keep the pressure at 42psi til then.

 

[Djxtrodinaire]

well I rode home and measured the psi were at 45 warm

Ta Kid I guess I just have to keep riding on then and hopefully everything evens out

 

[BIKE DUDE]

Double check the torque on the bearings in the steering head???

 

[ta-kid]

Just to clarify my earler statement on cupping,if that is your issue,you should be able to see it in the front tire tread pattern.There is proably pics on the net somewhere but basically between each tread cut in the tire the rubber will cup or taper wear between each tread cut.If you run your hand around the tire usully you can feel it if its enough to cause vibrations at speed.You feel a dip,like a cup ,or it tapers, so the next tread cut groove feels like one edge is higher then the one next to it,causing a vibration through the triple tree.
Hope I did not confuse you.

My 08 is smooth as silk.Sounds like you need to check for a problem.
