i am not sure if the tyre mark would still be there or washed off. that mark is usually on the inner edge of the tyres which gets slided on the edge of the wheel rim.
and if the tyre is loosing air then get the valve checked and replaced if needed.

post which keep a check on air pressure. if the pressure stays same but the wobble continues then get the tyre out and see if you can find the marked spot.

if you are running 1 tyre radial and 1 tyre bias ply- nylon. it happens.
it hase been dicussed widely before.

however if that is not the case then check for following things in order.

tyre air pressure.
has the front been installed correctly. with the right spot for weight balancing and right direction.

Yes both tires are bias ply I don't see any wobbling continuously anyways will take it to local tire shop just to make sure everything is right.

Re: Honda CBR 250R

Guys whenever I fill nitrogen on my tyres , my tyre deflates, is it because of the nitrogen or the person not filling properly?

each tyre will have a smalkl yellow or a blue dot on either side which marks the heavier point in the tyre.
on the rim the place where valve stem is the heaviest point.

hence the heaviest point on the tyre should be exact opposite to the valve pin which will balance the tyre well.

do you mean wobble after replacing the valve ?
if yes then check for air pressure. if the valve is loosing air and the psi goes down it is bound to wobble. monitor the air pressure everyday for a few days and make sure the tyre is not loosing air rapidly.

loosing 1-2 psi in a week is absolutely fine.

as a general practise. i lube every 500 and clean and lube at every 1000 km.

xxx km ( clean with diesel - toothbrush - grunge brush - lube ) - ---- 500 km ( lube well) ---- 1000 km ( clean - lube) -- repeat.

Wat about the duration for chain tightening?

It goes without saying, check chain-slack every time you lube/clean it. Adjust it when if falls out of recommended play.

Does anybody know how much power is produced by the alternator when the bike is idling? The manual gives the kW rating at 5000 rpm only.

Idling produces variable amounts of watts as there is constant draw from of power. Stator produces 340 watts with the engine running at 5000 RPM with high-beam on the voltage should be lesser than 15.5 at the battery terminals. There is a reason why it's supposed to be spinning at 5k RPM so that the pulses are constant.

coz thats the max power the machine makes. less than 5000 rpm it will vary.. post 5000 rpm it will stay same.

Re: Honda CBR 250R

I have a doubt guys, I know service intreval for the CBR is 5000-6000kms max? I'm at 6000km now but I changed my engine oil after 3500km because of my usage, I'm doing a 200km on Sunday n planning to service my bike after Monday. Also I changed my oil from Honda company used castrol oil to motul semi synthetic in the middle, is it bad on the Long run? I'm going to be switching back to fully synthetic for good, not that semi was bad but its better for the engine?

3500km because of my usage, ? what kind of usage ? track days ??

Also I changed my oil from Honda company used castrol oil to motul semi synthetic in the middle, is it bad on the Long run? i cannot say its bad. People try diffrent engine oils however sticking to 1 variety will be preferred.
Mineral / Semi / Full synth are all good at their own place . diffrence is the drain interval.
Mineral max 2000 km
Semi - no idea- never excited me to use something which is neither mineral neither synth
Synth - 5000 - 8000 km.

Synthetic can last 8k kms? The ninja 300 has a 12000 km service interval, does that mean Kawasaki recommends changing oil at 12k?

No oil will last so long and the oil level starts depleting under normal usage also, be it any type of oil.

Synthetic oil can last upto 4k-4.5k kms, but one needs to keep a regular check on the oil level.

The main reason I change my oil is due to my mixed riding style, which is usually 60-70percent sane riding with occasional bursts and a few top speed runs, hence my engine oil change interval is 3500kms, I know many mechs soo its not issue for me, usually if the oil is burnt its better to change to preserve the life of the engine, it's just my opinion. I just tried semi synthetic to see if anything was changed or affected, but the bike seems totally fine. Oil change intervals completely depends on your riding style, if u constantly keep the bike at high revs , its advisable to change oil every 1500-2000kms max, my riding is mixed and I usually don't go above 7000 rpm until I'm in 6th gear and there is wide open empty roads, if u ride really sanely and shift at the right rpms and keep revs below 6000 more than 90% of the time, u can follow the company's interval change itself.

Re: Honda CBR 250R

Some of you might not accept with me on my case.

Only my last oil change is shell ultra, it's been 1500 kms since then. Earlier I used honda synthetic oil, i used it for 5.5k kms regularly. Now after 1500 kms of shell ultra I find the engine is not as smooth as it was some 1000 kms ago.

But I will stick to shell ultra from here on, no questions asked. This shows the engine oil life can and will be always debatable
