Re: KTM 200 Duke

Rpm fluctuating could be coz of throttle body clogging with unwanted materials leading to issue in opening and closing of the valve. If it's showing zero under 20km speed with headlights on then it could be stator coil.

Re: KTM 200 Duke

Like there’s a 99rpm.com for Bajaj, is there a similar site for buying spares online for the KTMs?

Re: KTM 200 Duke

My speedometer suddenly started during 0kmph while riding. They after a few mins the idling rpm started fluctuating as well.

The last time the speedometer was showing zero kmph the stator was replaced.

But facing the idling RPM fluctuation for the first time. The bike was also not cranking. I'm not near home so won't be able to check battery voltage for a week or so.

Any list of suspected faulty parts for the above faults?

Re: KTM 200 Duke

During last month by bike was shutting down (console going off) due to blowing up of Fuse no 8. There was a short circuit (less than 100 Ohms) between the Fuse 8 terminal and the chassis. I had tried disconnecting many sensors and the cable joints but the short still remained. In the end the short would disappear after disconnecting the ECU.

After disconnecting the ECU the resistance between Fuse 8 and chassis would be infinity. But after reconnecting the ECU, there would not be a short circuit, instead I would get a value of 2000 kOhms to 6000 kOhms. At this value the fuse does not blow.

The bike was given to ASC and they found the speed sensor cable was damaged and it was replaced. My coolant level reduction problem was resolved after replacing the water pump seal.

But the fuse 8 blowing up issue has now come up again after 1000kms post ASC repair. The speed sensor cable seems fine visually this time.
Measured the resistance between fuse and chassis and value was near 200 Ohms, hence fuse blowing up.

So I disconnected the ECU, measured resistance between fuse 8 & chassis and value was infinity and then reconnected ECU and resistance was 2kOmhs. So now the fuse 8 is fine.

Can someone please check what is the resistance value between fuse 8 and chassis on their bikes? Measurements were done when the key was OFF. The chassis reference point used by me are the allen bolts of grab handle or the hex bolts of the tail light.

I don’t understand why I get infinity reading with ECU disconnected and then fluctuating readings (sometime 2k and 6k) when ECU is connected. If there is some harness problem (cable core is touching with chassis) then shouldn’t the resistance readings be constant irrespective of ECU connection?

Re: KTM 200 Duke

if you recently drained and filled up coolant, it is normal to see a little drop over a couple of days.. top it off and ride.. thereafter there should be nil to negligible drop in coolant levels.
if you are constantly observing coolant drop, there could be a few things causing this:
1. A small leak externally
2. A failed waterpump seal.
3. A failed headgasket.

I suggest you first pay attention to the first two.. look around the hose pipes/radiator area for any leaks. And also take a sample of the coolant from radiator and engine oil and check.
then maybe replace the waterpump and the seals (comes as a kit). Drain and refill fresh coolant and engine oil. Keep an eye on the coolant level and oil condition.

now coming to smoke part.. a tiny leak from a head gasket failure might not cause noticeable smoke. but if the leak is big enough you should be seeing whitish smoke.
if you see bluish smoke, then it is definitely the oil which is getting into the combustion chamber either due to bad valve oil seals or worn piston rings.

Re: KTM 200 Duke





Well my original post got deleted while trying to edit it, alongwith today's reply. VJ if you undo the 5 day old deleted post then kindly do so.


My coolant level drops, mentioning oil was a typo.


So I might have to check for head gasket leak. I do get some burning smell sometimes, is it due to boiling of coolant?


And when is a good time to check for the white smoke? At cool start and high revs at idling?

Thanku..3k! That is expensive. I will go for generic steel braided line.

Re: KTM 200 Duke

Hi,
KTMs steel braided lines comes with a metal tube inbetween near the t stem and headlamp area. Which swaps the hose from RH side of master cylinder to LH side calliper.
Which isn't required for most motorcycles which comes with RH mounted front brake discs.
This will cause hindrance on routing the lines.
Instead of you want lengthy lines go for RE Himalayan front brake lines.
But it's crazy priced at 3k.KTM ones would cost you 2.3k approx.

Re: KTM 200 Duke

What is the length of front steel braided brake line in duke? Want use in my fz 25 with touring handle bar.

Re: KTM 200 Duke

I echo what Manoj has pointed out here and add a few pointers. Oil level reduction can be caused by two things, isolated to each, blown or leaky stem valve seals and or faulty piston rings, especially oil control rings or a combination of both. If you have a blown gasket a compression test will be easily able to find it out or a leak test, especially works good. I'd suggest you start off with doing a dry and wet compression test at your SVC to determine the root of the issue.

Good luck.

Cheers!

Re: KTM 200 Duke

Hi,
Head gasket failure and water pump seal failures are two different scenarios.
If water pump seal fails coolant will get mixed with oil. Emulsified oil and wavy oil filter is a sign.
If head gasket fails your coolant will boil since leakage of compression will enter coolant loop and cause the coolant to bubble out of the radiator cap on your right side.
Another sign is white smoke. Occasionally you may even feel coolant condense on the exhaust outlet.

Oil drop is mainly due to worn out oil scraper rings. Check those if needed replace block and piston as assembly.

Re: KTM 200 Duke

Thanks man

Re: KTM 200 Duke

Nothing to worry. If you can find the spot it came off the rim, like you have a residue left behind, you can use fevikwik or double side tape cut to the exact size of the weight and stick it to the place. If you don't know where it came from, nothing to worry, you can continue to ride like that. The bike's tire is already balanced from the factory (stock tires), so these weights don't make a HUGE difference to your riding. If you can get it balanced after the Covid lockdown, then you can do it. Keep the pickle aside, nothing to worry, enjoy the ride.

Cheers!

Re: KTM 200 Duke

Guys, I have a problem.
The wheel weights on my front wheel came off while I was washing the bike.
Is it safe to ride my bike in this condition or can I attach the weights myself or should I visit the SC or a tyre shop? (SC and tyre shops aren't open right now so I'm in a bit of a pickle)

Re: KTM 200 Duke

how old are the tires and their condition ? make sure you are maintaining the right tire pressure. set the monoshock at step 3 or 4 (incase it's set to high or lower).

the wheels are balanced from the factory, and there is no 'set' no. of weights. probably is going to vary from wheel to wheel.. and if you want to know if it is possible the weights come off over a period of time, the answer is yes they could.
proper way to know is to get them checked/balanced again.. good luck finding a place that balances motorcycle wheels properly.
