Well Daniel. Part of the problem is that the Ninja is a 250 twin not a four (it only has about 30hp). All the Thai Ninja's are FI. So you might find more info on the American sites (US Ninja's are carbed). The Carbed Ninja is also very lean from the factory so if you have put a pipe on it but not rejetted then it will be way lean now (very bad for the engine). Why don't you talk to the guys that made your exhaust they have a Dyno and extensive experience in working on the Carbed Ninja. They have airfilters and rejet kits available. I just cannot remember their name at the moment. Just found it here you are .

There's something wrong with your Ninjette if she'll only do 140km/hr... First thing I'd do is check compression to make sure you engine is ok.
Understand you've got the carbed Ninjette, same as USA, right?
There are folks in the US reaching 100mph (160km/hr) on stock Ninjettes so you should be able to at least reach that.
With major mods they've had the carbed Ninja up to 111mph: http://www.thaivisa.com/forum/Kawasaki-Nin...al-t248352.html
Ride On!
Tony

The 250 thread fell all the way to page 8

I picked up a 2010 Green SE a few weeks ago and I've been enjoying the ride. Did anyone else grab a 2010?

Well, I was going to wait and post this, but since you've brought the thread to the front page...

I finally got the 85kg/mm springs in my forks. Wow is an understatement. The vague mushiness that was the front end is gone. It tracks exactly where I point it with out wallowing around like a 70 kilo bargirl on a pole. It does however really illustrate just how soft the rear shock is; that's up for fixing next.

Best 99.95 USD that you can spend on it (at least thus far).

Also had HEL lines installed, nice and linear action, the brakes work without getting spongy toward the end.

Good job Dave! Nice of you to give the old girl some sturdy legs to carry your big butt around- even 70 kilo bar girls have their limits!
What did you end up doing with the paint? Pics?
Ride On!
Tony

Well, I just tell them I'm not fat, it's the fuel tank for my sex machine. Also fat bar girls are more fun; they Don't get it as often and are more enthusiastic when they do. Errh, so I've been told. The Monster decals will go on in the next day or two, wanted to take care of the other stuff first (I am not a ricer).

Ha ha ha! Classic!
What's a ricer?
Happy Trails!
Tony

Ah ha ha!!! I just looked up "ricer"

(Ricer: from the latin word Ricarius meaning to suck at everything you attempt)

A person who makes unecessary modifications to their most often import car/motorcycle (hence the term "rice") to make it (mostly make it look) faster.
Most of these apply to cars, but still dam_n funny-

You Might Be A Ricer If… You have more exhaust decibels than your engine has horsepower. <li>You have aftermarket FRONT wheels for racing but stock rear wheels. <li>Your engine makes twice as much horsepower as torque. <li>17" rims up front, 13" out back on your FWD. <li>You ever painted your wheels to match the same color of your car. <li>You put your automatic car in neutral at every stoplight in order to roll it back and try to fool other people into thinking you have a manual transmission <li>DuPont gave up trying to figure out the shade you were asking for. <li>Your mod list includes stereo equipment, shifter handle, MOMO steering wheel, PIA driving lights, exhaust tip, but no REAL engine parts. <li>A chameleon lizard undergoes fewer shade changes than your custom paint scheme. <li>Your rims and tires are so large, that you have to install the tire / wheel from underneath the car because it simply won't fit in the wheel well going in from the side. <li>The dealer laughs when you bring your car back in for service under warranty, and you've only had it 6 months... <li>Your tires / rims stick out from the lip of your car by more than 1." <li>Your paint job is from the WRONG end of the color spectrum. <li>You installed spacers on your STOCK wheels and tires to get them to stick out past the fender. <li>You see cars like yours in a Shriner's Parade for Children and clowns are driving them. <li>You bring an empty Maxwell House coffee can with you to compare size when you shop for an aftermarket exhaust system. <li>Your Eclipse GS-T hardtop has a "SPYDER" emblem on the rear... <li>Your sum knowledge of suspension is: "the more negative camber, the better the handling." <li>You push your car through the staging lanes. That way, maybe you can break into the 16s by keeping the motor cool between runs. <li>You add a super tall rear wing, and a hundred pounds of aftermarket ground effects, neon and stereo yet you gut the interior and yank out the rear seat for weight savings. <li>Your rear wing AND your rear window have a third mount brake light... <li>The back lighting in the gauges in your A-pillar gauge pod work long before the actual gauges are hooked up. <li>You cut 4 coil springs and scrape the chassis on the ground. Sparks are cool when you corner at normal traffic speeds! <li>You have to find a way to drive AROUND speed bumps in a parking lot. <li>You install clear corner and brake lights. <li>You install colored bulbs in your aftermarket clear lenses. <li>You ever put neon on the bottom of your car, and then busted it on the first speed bump you went over. <li>You painted the UNDERBODY of your car to match <li>If your rear spoiler is taller then you are. <li>if you can fit fist fuc_k your exhaust tip <li>You have more stereo WATTS than engine TORQUE! <li>If your tailpipe extension is the most expensive mod you’ve done to your engine yet. <li>Your tailpipe extension fell off during a quarter mile race and you went three tenths of a second faster due to weight savings. <li>EVERY car in your class has a turbo pushing double digits worth of boost. <li>You spent $5,000 on the engine and you can not out run a stock Camaro, Firebird, or Mustang <li>You want the 'wastegate' sound, but don't want to install a turbocharger system. <li>You think Nitrous Oxide on your Hyundai Sonata puts you in the same performance league as the Chevy Corvette. <li>The automatic version of your car runs 2 seconds slower in the 1/4mile. <li>If the 1970 Plymouth Daytona Superbird has a smaller spoiler than your car does. <li>You think the Del Sol is a sports car... <li>A torque converter does NOTHING for your car. <li>You think a deep farty noise = the sound of high performance <li>If you think that horsepower is far more important than torque <li>If you have ever claimed that switching to a cone filter has given you more than 5 HP. <li>If you have ever considered installing more than one set of fog / driving lights. <li>If you claim that the aftermarket cold air intake system you just installed doubled your horsepower or took 2 or more seconds off of your E/T.

Just a heads up. With my 100 kilo(ish) weight, I've got the Ninja up to 156 km/h (96,93 MPH), GPS verified--totally flat out on the Nakhon Sawan bypass. Also, the speedo is some 7% optimistic; i.e. I pegged it at 100 and it was reading 93 on the GPS. Finally, I did 353,7 kilometers on 14,11 liters of benzine gaow-sip-ningun (filled to the exact same spot) and thus averaged 25,07 km/L or 3,99 L/100 km.

dave,
thanks for the info. I've been hearing more information from sub 80kgers and needed some info pertaining more to my weight division.

Is this the fastest the Ninja 250 can go? That's kinda disappointing with the 144k baht price tag.

A 20k baht two stroke can keep up with that.

I doubt the two stroke would ride as comfortable as the ninja. (no i have never ridden on one but i assume it would be a smoother ride)

I'm sure an old 2t could keep up. But with a 'plus' sized rider on it? And remember, that's a real 156; speedo would be reading some 167. Plus there's the safety factor; do you feel lucky punk is all I could think about getting one of those 'pristine' examples of a bike up to similar speeds.

You'd be surprised how stable an NSR 150 is once you drop the front end an inch or two. The newer NSR RRW's are even more stable than the RR do to a longer wheelbase.
I took a ride on a yamaha TZM 150 today, comparing it to my NSR, and I must say the yamaha feels much more stable. May have to make a switch here sometime soon. The yamaha feels more purpose built for higher speeds.

I don't want to threadjack, so thats all.

This is interesting I just looked up the wheelbase of both bikes and the proarm is actually 20 mm longer than the ninjette. 1335mm vs 1355mm...anyone want to double check? The info isn't the same for every site I checked

Not sure how a 2t would cope on a sustained high speed run, say Daves recent 1000km 'iron butt'. A well maintained one should be ok BUT seeing as this is LOS. very,very difficult to find.

Are you saying 144k is expensive? I think it's pretty darn cheap... Guess it all depends on your point of view. And please note that Dave's bike is pretty much stock and he's a big guy. Get rid of the terrible stock exhaust, add a powercommander and yank the baffles and you'll get another 5 or 10 km/hr on the top end. I used to cruise along at 170-175 indicated on my stock Ninjette, but I weigh quite a bit less than Dave.

Not saying it's expensive or cheap for that matter, just a 124k baht difference for a marginal performance gain. I agree it would be better for long trips for someone with the time to go touring, but for everyday use for normal people that have to work almost everyday, I don't see the worth.

Why buy a new Honda City instead of a 15 year old Mitibushi Lancer? Why buy a new ER6N/F instead of a 15 year old GSXR750? Some people like newer, reliable, warrantied, 100% legal machines with dealer backup and no hassle. I work my ass off during the week and if my weekend break was ruined by a breakdown in Nakhon Nowhere on an old piece of crap like some of the NSR's floating around then I would be extremely pissed off.

If you want to run around the village with the odd 200km trip out of town then you might get lucky for a year or two with an old NSR. Sooner or later you'll be in the cycle of regular substandard repairs, dodgy mechanics, ripoffs etc. If you're a good mechanic and have the time and patience to source the parts and enjoy doing the work yourself then I can see the attraction of these ikes (I absolutely LOVE 2 strokes) but for anyone else they're just a compromise to save a few quid IMO.

I agree.  For normal around moo-baan riding the CBR is rolled out.  For long rides the Ninja gets the nod.  If I still lived in Samut Prakarn the Ninja would pretty much never get used.





And that's the crux of the matter.  Did I need the Ninja?  No.  But I got it now and it fits the usage I need it for.  Was actually looking for a CBR 250RR before the wife bought the Ninja; that would have been my 'fun' bike (where I poured more money into it than was worthwhile-my time is worth something) with the little CBR being the old reliable and the Vigo for any other time.

Whats the difference in fuel consumption between the two bikes?

If you're asking me, about 15 km/L between the Ninja 250 and the CBR 150R.....

How much faster is the ninja up to 120kph when your really gettin' on it?

I dont know what consumption a 250 Nija has but my CBR 150 is currently exactly 1 Baht per km over months of usage running 91. Mix of highway (average 100kph +) and town running.

Ive never ridden a ninja...(must rent one for a few days ).......but from friends comments, "IF" the Ninja is faster up to 120kph its by a whisker only. After that it beats the CBR hands down. Ninja is blasted into oblivion by a CBR 250.

Anyone know the stock sprocket ratios for the ninja 250? and how many RPM's is it pushing at 150 kph? What's the peak RPM and when does it begin to redline?

This bike must be locked somehow.

Oh, and carburetor size.

When you're really on it? After about 40 or so quite a bit.

As an example. I was tooling around about 90 when a CBR 150 with Thais 2-up roared pass me. I dropped a gear and was fairly easily able to catch up, and blow past them at 130+ in what seemed like 15 seconds or so.



I think you'd find out it's more like up to about, maybe, 60 or so.....




I'll get you the numbers tomorrow; I've changed sites and I don't have the forumlae on this computer. However, the stock sprockest for fuel injected models is 43/14. Redline is right at 13K, but the rev limiter kicks in at well above that...can't tell you exactly though.

You do realise it's fuel injected right?

Although I agree that it feels suspciously light on power compared to the 33 BHP that's brandied around.
