1) Grease that lower chain guide, the one the left footpeg bolts go through... and make sure you lube your chain 'center rollers' properly, often.

2) Check your chain tension at intervals of the rear tire's rotation ~ i.e. make sure you don't just have a chain that is oscillating in and out of tension because of uneven stretch/wear.

3) Lube the 'upper' chain slide surface lightly, to reduce the amount of center roller rotation that constantly occurs.

4) When you check the chain tension, adjust it so the top edge of the chain is exactly at the lower edge/lip of the swingarm, at the prescribed check point.

5) Don't ride this bike flat-footed, ride on the balls of your feet, as if you've been riding off-road your whole life.



All these remarks are things I have become accustomed to doing on this bike, for precisely the same reasons you have now expressed.

 

 

A long shot but have you checked if the front sprocket locking plate is still mounted tight and both screws are still in place?

 

Yeah, and it's funny you should mention that, because I forgot to mention 'one more thing' I found that also helps:

The next time you have your rear wheel off to change a tire, lightly grease the surfaces inside the hub, anywhere the rubber damper cushions press against. It will allow them to move a bit more freely, so they don't get pulled slightly off-center by any applied torque, when you are accelerating or decelerating.

I did say 'lightly grease', didn't I?

Anyhoo... b4 I overstay my welcome yet again...

 

I have seem people using some type of gum in there so the dampers are in place, haven't seen anyone using lube, i will try if it works.

 

Thank you for your reply @DukeofSeven

1. The new ktm gen 3 foot peg is attached to a bracket which directly fitted on to chassis with 2 M10 bolts. There is no longer bolts like gen 2 which runs across to other side.

2. The chain is 2k km old, i checked it there are no kinks or streches, its just fine.

3. I will try that.

4. Adjusting the chain tension is the one i have obsessively checked number of times (can you share how you do it), i think its within the range. Adjusting the tension as described in the mannual make it little loose and gear shifts feel clunky. I keep it little tight to make the shifting gear smoother. I played with chain tension from loose to tight but the vibration doesn't change much. The only thing i am not able to do is torquing the wheel nut, i have ordered a torque wrench and i will do that and see how it goes. Mannual doesn't say whether the tension to be checked with lip of the swing arm or the base.

5. I have trying to keep my foot differently and thicker boots as well. The vibration is high frequency one, which sharp at that rev range and i can feel it.

Not torquing the wheel nut have any role in foot peg vibrations? i dont know.

 

@KTMasean i removed the chain sprcket cover and found chain lube gunk deposited in there. Cleaned it thoroughly and loosened the sprocket nut and tightened it back. Nothing changed in terms of vibrations.

 

Regarding footpeg vibrations i have checked few things.

1. The vibrations felt in that rev range slightly during acceleration but majorly during deceleration. I have tried revving to high speed and hold the clutch, i dont feel in vibes in there, as soon as i drop the clutch and engine revs climb the vibrations are back, so the vibes are there under the engine load.

2. I tried revving the engine from idle in neutral and also in 1st gear holding the clutch. Although i feels vibes in seat tank and foot pegs, they make no presence while riding, except for left foot peg. Also i feel There are more prominent left foot peg vibes when compared to other vibrations. So it is coming from the engine.

3. I tried pinning down the vibes by feeling through my hand, i noticed there are more vibes in the foot peg itself rather than the bracket. Also some strond vibes can be felt from gear lever.

 

Help me find which one is the engine mount bolts that is there in the mannual. There are two bolts at the back of the engine which hold to the chassis and engine hanger at the front. I am confused, which is the right bolt so that it can be checked for the given torque numbers.

Thank you.

 

So you are implying, by the pdfs, your bike is a 2024? Wow, I totally missed that. I definitely need to get more sleep.

 

@DukeofSeven yes its 2024 latest one, i really loved the engine for its smoothness in the usable power range, now vibes sit at 5k rpm which is around the cruising speeds. I travel and tour a lot, i am trying to make peace with it but its annoying if i think about it.

Yeah... Nothing is perfect, though; especially when you consider the inherent secondary imbalance of a single.

You could always change the final drive gearing to suit more your tastes (and move the 5K out of the way, so you're not sitting right at it, when you're droning on for an extended period of transit.

Anyway... good to hear you are happy with your ride.

 

@DukeofSeven yeah i have thaught about it, the vibes weren't there untill recently, so i am thinking to fix it, will see how it goes

 

One more thing you could try is driving your clutch into judder, and see if the vibes afterward are either worse or slightly lower.
The reason I say that is because, although most of the clutch is supported on bushing and bearing, the pressure plate is not. If it settles into place just a bit off center in the basket, it could actually induce a vibration at some speed.

Eh... it never actually ends, does it? At least I didn't bring up the possibility of aliens LOL.

 

Okay i have found the solution😅

Major issue was out of spec torqued engine mounts and foot peg bolts. The dealer service shop had torque wrench which was way out of spec and every bolt was overly tightened.

Baught this torque wrench from amazon. Loosened all the bolts and torqued it to spec which solved all major vibration problem i had, but there were still little vibrations to be felt in the footpeg while doing little aggressive engine breaking. I found the issue was with lugnut, after torquing it solved the foot peg vibrations completely. The happy part is bike seems more balanced and handles so much better.

I also got my ecu reset from the dealer which deleted all the learned files. Now my bike feels super smooth and awsm to ride her in best condition again.

Thank you for the help. Here are some images

That's great! Can you post pics, circling the bolts you loosened/re-torqued, so everyone can see precisely what you did to resolve this?
Again, congrats and good work!

 

Thanks mate.

Engine hangers were never touched, only the fastners which hold the engine in place at the back of the engine were torqued. In the above image the no 18 bolt, the upper one is aluminum and has no nut which should be torqued to 46nm and the no 18 bolt which is present below looks like made of steel which has nut and should be torqued to 50nm.
Apart from that the footpeg bracket, there two M8 bolts which torqued to 21nm and lugnut to 100nm.
