^^+1, the Ninja 250 is recommended to be idled for 5 minutes to reach optimum temp.
although I never wait that long

Hey Doga,

In my opinion, dont keep the engine on idle till it comes to optimum temps. Just make sure you dont abruptly accelerate or raise engine rpm too high till optimum temps are reached (Smooth Midnight city crawl riding) till then.

About engine temps, dont know too much about Dukes, but a water cooled engine is bound to feel hotter because the dispelled heat from the cylinders are transferred into the radiator before dispersing into the atmosphere, this puts more area of the bike emitting heat, it'll seem hotter but the engine should be okay. Dont trust me on Dukes particularly though, what i say is generic. They do have a temp gauge right?

Cheers guys.

What can I say but "A GOOD BIKE", apart from the fact that u must be riding it well.

Thrilled to hear that the Yamuna Expressway is complete and ridable. Excellent news, will be doing it on my way from Bangalore to Delhi. Just one question, are there many obstructions in terms of tractors and bikes riding opposite direction etc?

Cheers

not to bug you again. But, do these 3M tapes come as ready made ones?.

I'm from Mysore and after seeing tron bike pics, I went nuts to get one done for mine. But the best I could see was some "made in japan - kwality reflective stickers - 220Rs". They cut them out from a large canvas sheet and put them on your wheels. I wasn't sure whether they would be as good as 3M and didnt go for it.

I saw some youtube videos where these come as ready made, as in a semi circular ready to stick tapes.

bike running rough

since day one.. bike has been running rough..

first it was the chain was tight.. after that got done the bike is not running suffocated.. however it runs very rough...

not smooth at all.. like as soon as the bike is at around 15-20 and less its like its running on stones..

feels like the front wheel bearing are stuck but got the wheel checked.. its just fine.. dunno if its the front sproket thats running so coarse.. or something else..

and after 2k km the chain is still very noisy.. got the chain checked thrice and lubed 3 times in 2k km... no go.. still the same...

Does it feel like on stones even if you freewheel? There's a certain strong pull back that this bike has on gear which some dont like, but that doesnt seem to be the prob right?

exactly.. even while the bike is set to neutral and still slowing down from say 30-10.. it feels like running on something rough.. feels like front wheel bearings are like worn out.. got the wheel checked and it just runs fine ..so only culprt left i see is the front sprocket..

dont know what more to say...

this coarse riding cant be felt at lower speeds and vanishes as soon as the bike gets below lets 8-9kmph... till then i can litrelly feel it in the grips as if its rubbing off with every revolution.... no sounds .. just a feel.. tried explaing it to the SVC guys.. they just dont get it..

more like a feel of running with metal tyres than that of rubber...

I'd suggest:

> Get wheel balanced
> Check/refit all cables running to the front wheel hub (including the odo cable)
> Check brake pads, freewheel gaps and disc bends.
> Take it to HSC, ask for the chief mechanic, get the bike on the lift and manually freewheel the front wheel. If you feel it while freewheel riding, the mech should feel it manually rotating it. If you cant feel it while on the lift then its probably because of load and we'd have to move on to suspensions etc.

Need one thing clear. Just want to make sure its not the 'ffrrrrr' that comes when tyres are new right? Because it happens in the same speed zone you mention.

Anyway hoping for a quick resolution.

Cheers

Yes indeed you did clear some of my misconception. However, Our CBR's when started have an ECU that pushes the rpm to around 2k before taking about 10-15 secs to get back to a 1.5 or 1.6 rpm depending on engine temps. I agree with mostly whats said in the link you provided, but there he measures with wave pulse which doesnt measure fuel/air richness while starting or ECU compensations which surely kick up at every start up, especially on this bike, doesnt with my activa though.

So what i do is basically anything above 40 secs on the signal i switch off and put the engine back on Standby so the fan can run and the ECU kept ready. I start engine just before the signal turns green and most often than not, exit slowly to aid the start up to be smooth.

Anyway, thx for the link and info.

auto choke dude, even my P220 has that. The ecu doesnt need to compensate when the engine is already warm such as a signal stop and that is what i care about. a bike does not cool off even with a fan in 1min which is the typical signal timing. so 40sec is still long.

Anyway my point is i switch off @ 15sec and my bike is fine hence you dont have to worry about your starter motor or fuel consumed for starting the bike.

Like i said, by warming up i mean steady rpm which happens in my P220 in about 10-30secs depending on the surrounding temperature. steady rpm as in when you accelerate the rpm should rise smoothly and not jerky.

and like said below dont accelerate hard until optimum temp is reached. But you can start off as soon as ur rpm is steady.

True about auto choke, but my bike starts on 2k rpm before settling at 1.6k in about 11-12 secs (even when the bike is warmed up). The reason I keep the fan on is not to cool the engine down in one min, but if the ecu calculates 'fan switched on' at or above 98 degrees (on a CBR), then i wouldn't switch and keep the engines off, i'd let the fan run and do its job.

Agree on the fact that starter motors have evolved and dont usually give too much trouble these days even after repetitive, quick usage, no issues on that. You've even opened my eyes up with the fuel consumption thing. The 40 sec mark i maintain for signals is just a personal choice with this bike which i'm sure i'll change if and when i'm totally convinced.

Cheers mates.

Burning smell from the front

Whenever I start my CBR, within 1-2 min I do get a smell which feels like something is burning (it comes from the front side of the bike). I felt this 2-3 times, going to the service station in a day or two but since I had a horrible experience with the honda service provided till date

and wanted to know if there is a specific reason for this burning smell so that honda service guys cant tell me 1000 possibilities and charge me for it

**aargee** · 07-03-2012, 12:34 PM

^^^ Smell is quite common; idle the bike & you can smell more; its from the exhaust & the catalytic converter in action.

Thanks aargee

, just wanted to check if it is safe? I didnt experience it earlier though....I always start my bike in idle position for 2-3 mins but this smell started coming during last week only.
