What can be solution to this problem with the carb!? I've done changing the butterfly thing but still the same.. every 10000kms changing the carb it's a pain again and again coming up with the same problem... Any help will be great..

it was found that my one of my cam lobes has eroded off by upto a millimetre

Interesting. Never heard of same issue on bikes from my group so far. Will note this for further checks.

Issues.... Rocket boost problem which happens at 7k rpm and than after 8k rpm it's goes like a rocket passing speed of 110-120 in a breeze... 1st problem started at 17k Kms ...* after which I changed the carb at 24k Kms... the 1st carb I changed and again after 35k kms same problem.. I've gone to local mechanic whom I know got it cleaned and everything.. it worked for a week than again the same problem! I've reached 49k kms now.. still at low rpms it's good but Now toh it's worse.. It gasping for power/air/fuel at 6.5rpm! I don't know what it wants but it's struggles at that range, where I guess in that range is usually you get the peak power at those rpm levels.. but clearly I'm not.. ..while downshifting from 6 to 5 or 4.. even if the rpms goes to 9k on 4th gear, it won't push forward, like being stagnant there.. it will decrease speed very quickly but than climbing up, it sucks! I feel like changing the carb but than again after some moments of joy, riding smoothly for*8000/9000kms. Again this problem will come! I'm tired of all this.. sometimes..

And again another problem I've started facing recently is the tankslapper problem or in other words termed as Speed wobble or death wobbles when cruising around 120kmph.. 1st I thought it was because of uneven roads but no, even at speeds of 90/100 the handlebar tends to vibrate and give a feel of wobbles.. I've checked the cone setups, the forks, suspensions, even changed at fork oils recently at 40k Kms but still nthng could be found any idea what could be the reason of this..! I've Inspected my front wheel for cracks or bent but nothing.. but however in the rear I have this little hump, but it's very small, not noticeble from far only when you look closely when rotating you will see a hump.. no air leakage nothing .. can that pose a problem?

Please Advice... I'm in desperate need in some guidance... I'm literally tired but somehow not giving up on these problems which are temporarily...*

Bro i think you should check your engine kill switch or the ignition key area. Use carburettor and brake parts cleaner to spray within the holes and oxides, if any, would be removed the bike will be normal again power wise. Most probably it’s one of these issues.
Now coming to the tankslapper issue, the amount of money that you spent is insane. I want you to check your rear suspension to see if its fine and no oil is leaking from it. If no oil is leaking, i would advice you to increase the preload on the rear suspension by one or two clicks and the problem should go away. Let me know if it worked. Good luck!

I then inspected the all oil jets and yes indeed found out one of the jets near the right exhaust valve area was fully blocked, this was the exact lobe which had worn out and failed.

As you can see from the pic, only the right side of the head(top side in this pic) of the cam guide is fully worn out by 1mm-2mm, where as the left side (bottom side in this pic) is perfectly 100% fine and there is not even single skore mark on the left side, oil channels push the oil from left to right. So there was blockage in between somewhere due to gung or jets were clogged and only the right side of the head intake/exhaust cam lobes was starved of oil completely, eventually the left exhaust cam lobe/valve which was the one that failed on me.

I've had a similar experience on my KTM, Bajaj 200NS shares most of the same internal oil circulation/spray design.

You got it the other way round. I think in the pic, the left side of the camshaft holder (away from spark plug hole) is worn whereas the right side (near to cam sprocket/chain) looks good. It is as if the cam chain (RHS) was putting a lot of weight on the camshaft causing the other side (LHS) to get worn. As we can see, only the lobes are lubed by the nozzles. The actual shaft is lubricated by those cut-outs in the U-shaped portion. They look large to be blocked by gunk/debris. What scares me is you say you changed oil every 2.5k-3k and still this happened. Definitely not the best design. In CBR/RTR/FZ/Ninja/GS150, the camshaft itself is hollow, lobes have holes that spray oil - but the U-shaped portion that is held by the holder/guide (in CBR/Ninja) is lubricated similar to KTM only.

I'm assuming this the rainbow like discoloration you are reffering to in the below pic, and yes almost all NS with a bad tiktik knocking sound I've seen have badly scored cam bearings like below

I have negligible experience working on this Motorcycle but when it comes to obvious signs of oil starvation the first suspect would always be the oil pump. Does all variants of the KTM engine come with dual oil pumps or is it limited to a few? P.S. A friend of mine who is a mechanic wanted to know if you guys who faced oil starvation had used any oil additives or used materials that leave a lot of lint to clean the oil filter cavity.

Has someone noticed the tiktik sound that comes from the engine of both the Pulsar NS200 and RS200? My friend bought his Pulsar NS200 in June 2019 and he had that sound from the beginning, but it was subtle and wasn’t so noticeable. My Pulsar RS200 2015 model also had that sound and upon closer inspection on January 2020, it was found that my one of my cam lobes has eroded off by upto a millimetre. The mechanic, who is well known to me said that this has happened due to high speed riding and that the engine oil can’t lubricate the cams properly at high rpm’s, although i doubt it because at high rpm, the oil pump works faster which should pump more oil. I always used Motul 7100 20w50 oil. Anyway, i trusted him as i do ride the bike extensively and also take it to the highways at least three times a month and do high speeds. They replaced the cam and now the engine sounds smooth.
Going back to my friend’s NS200, the tiktik sound was somewhat contained till February 2020, he completed 9k kms by then and stuck to Bajaj Dtsi 10000 20w50 as he wanted warranty. At 9k kms he decided to switch to the Dominar 400’s oil, that is the Bajaj Dtsi 10000 10w50 and after that the sound just kept on increasing to a point when the tiktik sound was audible more than the exhaust sound in idle and the sound increased with increase in rpms. I thought maybe the tappet clearance were out, and a simple visit to svc would solve it, so we visited svc on June 2020. We waited until the tappet clearance was done, and started the engine for test and surprisingly the sound was still there. The mechanic who worked on my bike opened the head and upon inspection, it was found that one of the cam lobes was eroded the exact same way as my RS’s. The same lobe, even the pattern and depth was exactly the same. It was really surprising to see a very well maintained bike with 11k kms on odo with an eroded camshaft. The svc guys replaced it free of cost, as the bike was still under warranty and their statement was the same. “The bike gets ridden very fast due to which oil cannot reach the cylinder head properly and lubricate it”.Upon asking if its a manufacturing defect, they are denying any. My friend rides very sedately in city and rides fast occasionally on highways, the rest of the time cruising at around 90-100km/h. My brother owns a 200NS 2013 model with 39k kms on odo amd his bike hasn’t had the issue, although the bike was ridden pretty fast. Since that time onwards, i have seen many NS200s with the same loud tiktik sound which increases upon increase in rpm and i am pretty sure that if not all, most of them have got this camshaft issue. I think that this is a manufacturing defect, and it has affected a big percentage of NS and RS200. It would be very grateful if you throw some light and maybe share your experiences if you have got any. Thanks!

Apart from the Duke 390 and 250 all other models of the Bajaj KTM clones use the single feed oil pump. The evacuation pump or the scavenge pump is present on the D390 and the 250. I did use Liqui Moly shooter oil additive on my Duke, and it's a worthless investment to be looked for and considered for. No lint, no nothing. On most KTMs and KTM Clones, you will have metal shavings on the strainer located below the engine but that's pretty much it. Personally, we haven't come across lint or any fabric material for that matter. Though you have to proactively clean the strainer and replace the oil filter, as they do catch up quite some filth.

Guys, found the leakage just below the suspension. Below the nitrrox box. I heard the nitrrox box is filled with a gas, then where this liquid could be coming out from ?


Rear brake oil I doubt it .... Because the amount of oil leak is more and brakes are working perfectly

Hello guys, I am a new owner of a red pulsar 200ns which I got two days ago.

Ever since I got the bike I have been following the manuals method of breaking in and keeping the bike at low speeds. If I am correct the speeds indicated for the first 1000km turns out to be about less than 4k RPM in every gear. Now my question is, is it alright to occasionally go above that rpm limit? I am honestly not enjoying the bike at such low rmp, the low end feels a lot like my old xtreme, that is to say nothing special like I was expecting to blow my mind. Though the bike really comes to its own in the mid and top end above 5k rpm that's the kind of fun I want from this bike. Now at the present moment since I left my job I don't need to drive as much and will b be using it occasionally, so completing 1000-2000km at these insanely low speed and rmp is going to be a chore I feel. What do you guys suggest?
