More than hurt, a great embarrassment. The kind of looks you get means, oh!!! did you pay so much to get struck here? And not to mention that women are good at recollecting & associating things of past for any issues in future

IMO, servicing has nothing to do with this issue.

Though I planned to cross 9K RPM during the initial run, I didn't surpass 7.5K at any point in time during the 1st 1000 Kms. And didn't cross 5K RPM during the 1st 500 Kms run.

Service got nothing to do with it, Right. But was it powerless just from the beginning of usage ? Or just now you are facing these kinda issues ? Caz if I can analyze you had happy times and grinning FE figures during the initial run ? Didnt ya ? Something like 38's and 40's right!?

Guess your fate is sealed now......and you paid for it..


My guess is ,your run in has no relevance to your present,problem.All modern engines can sustain 75 % of their rated RPM limit during run in.

Agree with you 10000000%

@ALL looks like problems after first service exists, and main culprit is the A.S.S. not filling proper oil or level, and FIXING THE OIL FILTER THE WRONG WAY.

My reply in-line.

+100 had same experience with my friends R15 last year which did Max 115 with is GF as pillion.....where he lost to fourth
1&2 Karizma,3 my P-180
She makes fun of him every time when we meet ........

Darkknight.. I am proposing possible causes..I don't own a cbr 250 and had not been on one either. I don't have in depth knowledge of it's engine.....so take my observations ..as such ,and don't assume it to be correct.
1. The engine of cbr is unique in many ways...the crankshaft center is offset forward towards exhaust by 4 degrees to ease compression stroke downward movement...this does reduce vibes...but the engine also has a Balancer mechanism.....Any bike that has balancer is bound to have vibes problem IF the balancer is not set up properly....This may be one of the reason....apart from advanced ignition map for better FE.

Thanks ,will get this checked .

2. The lunging forward on leaving throttle is because of engine breaking characteristic of any 4 stroke engine, and will happen only when RPM to gear ratio is tall..ie., it will not happen on 6 th gear at 50 Kmph but will happen at 80 or 90 Kmph.

Never happened in ninja,220,rtr or even the r15.In fact not even one of the bikes I have rode.I tell this from around 4 lac kms experience of riding smaller 4 strokes.

3. This is 4 Valve per cylinder bike with a good fuel efficiency.With a leaner AFR ratio the engine will generate higher temperature, and a new bike whose internals have not worked and mated with each other, will definitely have more friction areas to smooth down.this also creates friction and heat..using 10w30 oil in our hot climate is another reason..a thicker oil like 20w40 will reduce this heating.

Am using 20w40 only.but this I can live with as it's expected in very heavy traffic.

The Liquid Cooled engines have heat sensors which help keep the engine temperature nearly 80 to 85 C.The circuit Actuation bypasses ignition switch so that if the radiator motor is switched on and we switch off the ignition the cooling by runing of the fan must and will continue.Not an issue.
In Injected engines the pressure required for the injector to spray a fine mist of petrol requires high pressure, which is developed by the fuel pump. so every time the ignition is switched on the pump will work and ensures that adequate pressure is maintained..

R15 had radiator fan disconnected with the kill switch.so that it use to run even when the switch is off & so was the fuel pump which didn't use to turn on evrytime switch was turned on & off.again it's a design thing so need getting used to that's it.

anyone having any idea about valves adjustment & shim measurements ?

How would I know that? I didn't have another C250R to compare. Like I said before, pls wait for my updates. Thursday should be max. If no one responds, then lets look for next steps.

That's what HMSI also says. If there's some serious issues, first thing to get hit is FE. Since mine is nothing less than 35, they don't suspect anything serious.

Lol!!!

That's what I believe too; but sometimes, it just gets over.

Lol!!!

Don't compare GF's with Wifeys!!! Both have completely different attitude. GF's keep hitting at all the places so at some point you get numb on those. But Wifeys know all your weak points & they hit on the bull eys at the right time, that pains like hell

DK - It was difficult reading you post, from the little I could gather...
Valves adjustments eh? From my little understanding, the valve clearance needs to be inspected & the shims needs to be changed accordingly. I could be wrong though & the valve clearances are done every 6K kms by ASC.

Sorry for the OT, but could not stop laughing. Experience(you) speaks and experience (me) relates and recollects.

Hey anyone got their hands on a frame slide yet??

Most are waiting to get their hands on the bike first.

lol i know but a few do right! Was asking them btw anna any idea where i can get a tank pad for the CBR in Hyderabad???

What a relief sorry God for blaming you..I thought you singled me out for the "Treatment" till I saw fellow homo sapiens riding in the same boat.
