mania

I just got back from a BKK to CNX run on gasohol and hit 164 kph.

Wow that is a long ways on a smaller bike.

Did you do it in one ride or break it down

Yes sir stock gearing, but it was a cold day last week (10am), 95 benzine,

Sorry did not see this reply till now

Cool...........You know I have never even tried 95 Benz since gasahol 95 has always run so well in

bike & scooters

Might try it just to see how it feels in comparison.

I watch on BBC 2 coverage and Cal in interview said that Herve came down with pen and contract to sign and Cal said he had his chance last week to do that, so still not clear what's happening.

Yeah I saw that too & wondered what is going on.

You can read back on some news here...

I read some last week & from what I could tell it was all rumors

But yes seems some bad blood there now & that is never a good thing

Cool man. Your bike is on its way.

Please inform us about you dig regarding ecus.

What is the estimated performance increase for ninja 250 after pipe, air filter and aftermarket ecu?

Yeah sometimes fun to tinker around a bit.

Power estimates I am not sure as it is harder to see dyno's for this model now that most

of the world is running the N300

I did see alias post a dyno of just his pipe & showing about 2.75hp gain for pipe alone.

He said no air filter was changed for the dyno just the pipe.

So not bad at 11% bump for just pipe.

After I am all sorted I may go see if Big Wing here is running their dyno yet just out of curiosity.

I would like to get a few more rides in as the first two were kind of surprising & I would like to see

how the top end has changed as well.

Was too busy today but hopefully tomorrow or later today,

mania the pipe fits well to the bike nice angle, not too big not too small this is how a aftermarket pipe should look like. When i still had a cbr250 i wasnt able to find a good looking pipe at all.

Thanks &

Funny you mention that as it was a selling point for me on the Devil.

Many cans are just too big & not what I wanted.

i am a kk guy http://www.krispykreme.co.th/index.php nothing like a quick ride for donuts and coffee

Wow a dollar a doughnut eh?

Them KK doughnuts are pricey

Looks great mania. I heard good things about devil pipes.

Now all you need is an aftermarket ecu to get the full performance from them.

Did you check if they sell pc 5 in Thailand for ninja 250?

Thanks LL

On PC-V

I have seen some folks selling used so I know they exist

but it would be easy for me to buy in the US & have my son send it via post to me too.

Just reading a bit about the various ones available, PC, Bazazz & Area P/ Fuel Moto

Blocking it off isn't a big deal- all you really need is the right size plastic cap- it definitly makes a difference.

Here are instructions and pics for my application- it's most likely similar for every bike:

http://www.brocksperformance.com/Instructions/ZX14/996395.pdf

Yes I recently saw a guy using a marble on a Thai site to block off his N250

If you go to a full system, unless you do some tuning and block off the PAIR valve, you'll very likely have some deceleration pop no matter which brand you purchase- if you're just getting slip-ons it shouldn't be an issue.

The exhaust I'm having installed this week comes with the PAIR valve block-off kit, and I'll be doing some FI tuning as well- even with that, I still expect some issues until I get the ECU flashed- even though its a different bike from yours, you'll probably still have to do some tuning as well when you swap your header- it's a byproduct of the increased air-flow of a freer-breathing system.

Yep that is the truth of it & to tell you the truth I liked it better in many ways when it was jetting changes instead of ecu related

At least it was easier to do yourself & cheaper.

I have heard a bit about the block offs & seen pictures but have not

used any

I recently changed my pipe & air filter on my N250 & of course have the deceleration backfires

Although not as bad as initial run I will be dealing with it & probably need to grab a bazazz or PCV

So the block offs help a lot do they? I wonder if someone has done any on the new FI Ninja 250's?

Yeah the rain made it very exciting.

I initially thought Marc was done & could not handle the rain/wet but he proved me wrong & clawed his way all

the way back.

The Ducati of Dovizioso impressed me in Qualifying & then all thru the race so did Hayden really

especially not plowing into Rossi when Rossi went down.

Then of course Pedrosa was very good even after his early off track excursion

Crutchlow? Awesome & glad he has some bargaining power to help in in his time of need.

Although I am sure he was glad the race ended as Marc was on a mission

I felt bad for Dovi & thought maybe he could hold onto that 3rd

Very good racing I loved it !!

Oh what a great race that was

Really Enjoyed it !

Are you sure about this?

Yes I think I am

Imagine you have a wheel say it is what ever diameter....17" for instance

From a starting line/point ...Imagine it makes one revolution...it has traveled x amount of inches

Imagine X amount of those revolutions per minute it has traveled x amount of inches per minute/ per hour etc.

That is the beginning basics now you need to visualize all the ratios of various gear configurations

Your idea about a higher revving 150 vs a 500 only makes sense if they both are turning the same gear ratios.....They are not

The charts are correct...Or will be if you input the proper info of what your running.

It is math plain & simple .....well ok maybe not simple at times lol

Does it works that way? What about the difference in hp and torque?

Sent from my GT-N7100 using Thaivisa Connect Thailand mobile app

When your looking at gearing you are looking at distance traveled in what is called gear inches

That is arrived at by gear inches & wheel diameter

The distance is termed by a revolution so rpm is what is needed to be known not hp or torque

PS: Very good help section on that site

Go click help > Help on using GC > Enter Manually

Or click resulting speed etc for explanations

Or Gearing Basics etc.

PSS: Remember this kind of thing os all theoretical too

meaning you will have wind / drag etc which will make each persons situation different

But it is a good guideline to see " Theoretical" speeds etc.

LL I really think that is the bikes capability....Here is a theoretical calculator for you to play with....

Now my friends er6 maxed out at 220 in top gear without hitting redline and he has quite a few mods....pipe, sprockets etc!!!

I always liked that site

It is cool to look at the various gearing configurations & their effects all else being equal

Nice site mania! But at the moment they don't have the charts for our cbr500R bike.

Load the Honda CBR250 & then I guess you need your primary ratio which I guess you have it in your manuals?

Then

Just load your sprocket sizes ( also not online for Honda??? )& rpm range & change tire sizes all in the custom or current section

Then save as your personal profile & it will save as a cookie on your computer

The so called white carbon vinyl sticker hasn't worked so will try and find a whiter one hehe.

heheh mai bpen rai but yeah it is kind of an eggshell white isn't it?

No worries just go straight white wrap ? ..I think it will look cool & you can always add

some brand stickers you support

Sound like a busy little engine doesn't it!

Has a very decent sound

Thick up top &

Beefy down low too

I think if we closed our eyes & none told us what bike this 600 was

we would all say wow pretty beefy for a stock bike with stock exhausts etc.

I know I did

Well Happy Birthday soihok !

About Lemans I would have to say it was a bit of a surprise to see

Dovizioso get front row.

Good on Ducati though & getting more brands into the final fight makes it all

the better for us spectators

Crutchlow nursing a small fracture near his shin

will see how he goes.

Strange things going on with Cal, when he seems to be doing so good.

I know !

I kind of hope he pulls a great race out there in France

Maybe that would give him some bargaining powers

Does seem weird for them to be screwing with him but I also do not know the history

of him not signing for 2 years before .

these guys, the non-riders who buy new imported bikes, are OUR best friends in LoS. They pay full retail, all taxes, add expensive bits, ride em once, park em, change their underwear, then sell em! All we have to do is wash off the seat.

We had the same thing in San Francisco with the DotCom yuppies in late '90s - early '00s: i was not alone in snagging a basically new Ducati for a song from one of these dweebs. Bike had 1600 miles on it!

Well that is what I was hoping when I saw these sites with all these low miles bikes for sale.

But that Financing deal is the killer because they do not drop the interest for prepayment in full.

So the used bikes owned by the finance companies are usually higher priced than new out the door bikes.

Yet they sell because the next Thai lines up & takes over payments & has enough side money to pay off the previous

debt jockey's small deposit request

FP2

I actually got the CBR 250 up to 170 kph the other day. Heres what was needed:

Stock gearing?

I'm getting the US-spec version (200hp/210hp with ram air- with my mods I'm hoping for ~205hp at the rear wheel

That sure made me smile

I am sure it will make you smile too when you twist the wrist
