You are right - I stand corrected.

Guys---been reading a lot about how fully synth should not be used till the bike has done about 10k or so. Now...immediately after my first service, Arif at PBK Hyderabad suggested I go with fully synth (my bike had done 1200 then) and I went along with him

.

I have already done about 2000kms more on the bike, after that...do you'll suggest I drain the oil and go back to semi-synth or has the damage already been done?

Hi, I'm not sure about this but I heard that like R15, Ninja 250R also comes with synthetic oil from factory. So I think you'll not face any problem with your engine.

Dude, what engine oil does ninja comes with from the factory? Fully synthetic or Semi synthetic? I think Castrol activ Xtra 20W-50 is a fully synth one. If it had came with mineral or semi synth oil, we should only change it with same thing no? Doesn't it make any harm if we change it to fully synth suddenly in first service itself?

Sorry on those a bit confusing lines...

That is one complete sentence to be read and should not be broken down into 2.

All i mean is that the Piston separates the complete engine into 2 regions- The combustion chamber(Where both air and fuel enters in a ratio and gets burnt ) and the other side is where the crankshaft and the other engine moving parts are their. So the place where the crank is their.. this thing i mentioned as the engine oil side

.

May be this could help...

Active Xtra is a mineral oil. Doesnt really last that long.

the bike comes with the semi synth oil from bajaj. please remember that no company will put any oil which is bad for your engine.

what is important is that one should complete the running in period as explained in the manual.

it is better to continue with semi synth/ ordinary mineral oil at least till about 7000 kms or so.

i have given a detailed write up on this in the engine oil thread.(http://www.xbhp.com/talkies/universa...tml#post466124 ) in Indian climate esp in south India where there is no extreme cold, your ordinary mineral oil will do its work very efficiently. Extreme cold may cause it to loose efficiency during starting conditions.

i will not personally use fully synth till atleast 10,000/- kms or more.

what is important is to change the oil and filter at the recommended time / kms run whichever comes first.

Came back after a blast of a ride =) day trip to Hyderabad and back, to meet an old school friend who I had not met for 8 years. Caught up over lunch

Left at 5am today, reached Hyderabad at 10.30am, left Hyderabad at 2pm and was back home 7:45pm! Trip meter: 1,138 kms.

And thanks Yasser for the tip - I rode the 'banned for motorcycles' outer ring road expressway on both way in and way out!

By the way - I tested out my Osram 4300K mega white bulbs. What an improvement over stock illumination - same difference as between a 40W yellow bulb and a 40W energy saving florescent bulbs!

Errr, I don't think so. It's a fully synth one.

Thanx for clarifying bro.

Whizz, the Activ Xtra is not fully synthetic. Kind of semi-synth, if you will.

Ten Hut (In Facebook) At the track...this Jan...the R15 gang from Pune rode the Ninja. Now they had ridden it at lavasa and on the highways before too. But once ridden there a good rider came back saying "I am sorry I ever doubted you" ! He was addressing that ...to the machine.
The Kawasaki Ninja 250R is just a fantastic machine and thats why I wanna punch every sucker who says 'its a good machine but not worth 3 lacs' ! Wanna tour = ninja, wanna track = lol ninja, wanna screw some bad roads= ninja ! Wanna look like a poser = ninja ! Want to have your headlight on all day long = ninja !

I'm lovin' this... that's so damn true!

yeh good ride " Friendly Excuse to Ride " .

this osram is the same specs as the stock ninja bulbs ?

Is it possible to list the tips for riding on the banned express way ?

**aargee** · 02-07-2011, 10:24 AM

@Bluevolt - Does your Osram 4300K give a whitish light or still the same kind of yellowish mix like Philips Xtreme or ordinary Philips H4 60/55? Pls can you confirm? Tks

Bluevolt , you must have tremendous stamina and an iron backside....Gosh can't even dream of such trips.... Take care friend

**vkuchhal** · 02-07-2011, 12:45 PM

Just a thought... In case of the battery running out and isolated places can't we use a set of (9V +1.5V *2 )=12V battery combination to jump start our bike battery.

Can that be done?
