Sounds like Big Wing is the place to be.

Great building

Dyno

And an experienced mechanic(s) to set bikes up.

I'm sure Kawasaki will be looking to improve their showrooms sometime soon or at least open one that's more maintenance orientated.

They really are great. The mechanics are very professional and meticulous in their work. Up to western standards for sure. They also had free trips to Kao Yai and to Malaysia to watch the Moto GP.

Mmm it seems like there is alot more to it than just adding fuel controllers/maps,exhausts etc to try and get these bikes running smooth and delivering full power i know the dyno reads low but 130 bhp is still alittle way of from what it should be.

Yes, about 20 HP at the rear wheel assuming the dyno was accurate. Still more than enough power for a noob like me though.

AFR is the most important graph to have, please make sure it's right before you give the bike any beans with its new tune.

I of course lost the warranty on the engine, but Big Wing assured me that everything was fine with the bike and the mods I made. I've put a few thousand trouble free kilometers since I have made all the mods. I even rode from Hat Yai to Kuala Lumpur and back without any problems. However, I am still very curious to see the AFR graph. Thanks for the advice.

Sorry to say this Mr Sumet and I'm not instigating an argument.

But I just want to understand why you went for the Thai speck bike Vs’ the imported bike with its full whammy of power.... You are obviously chasing the dream of attaining 'full power'

Some would say they bought the Thai spec bike because they feel more comfortable that it has a year or so warranty.

But modifying it with a 3^rd party ignition and fuel modules will void such a warranty, hence the reason Big Wing wanted nothing to do with such a modification

IMO a stock import would be more reliable than a Thai speck bike that's been fettled and had Joe Blogs play around with the bike's ignition and fuel maps....

When I first bought the bike I wanted the warranty, full dealer support, and a guarantee that the bike could be quickly registered and plated. Red Baron told me it would take 6 or 7 months to get a plate. Big Wing had the bike registered and plated within a month. I was going to wait for the warranty to run out and then derestrict it, but after a while decided to take a chance and do it early. I have learned a lot and quite enjoyed the experience.

Yes, Big Wing didn't want to install the full spec power converter, but they did readjust the fuel map after it was installed. The person who installed the full spec power converter used to work for Honda Racing and now owns his own shop (Big Ban Modify Shop). He certainly knew what he was doing.

Here is the final dyno for my bike. 99.40 N-M converts to 73.3 ft lb, which is pretty close to the 77.24 ft lb that Motorcycle U.S.A gave it.

That's hp graph looks a bit of a mess, not very smooth above 9500rpm and would be a handful to push hard at the track. Here's my Dyno numbers from Dirt shop which reads really low. Blue line is bone stock 08 CBR1000 and Red line is with full Yoshi, IRC and PCIII.

This Dyno chart is from the Tyga Dyno,

Green line - 2012 CBR1000, full Yoshi, zbomb and bazzaz Zfi

Red line - 08 CBR1000, full akra, zbomb and bazzaz Zfi, modified head and cams

Yes, yours looks much smoother. The stock reading from the Dirt Shop dyno looks a bit messy after 9,500 RPM as well. Anything I can do to improve mine?

The US spec bikes are restricted above 10,500rpm and that's what you see in the stock graph, the IRC-1 or zbomb makes it full spec but you need a fuel controller (power commander or bazzaz) to fix the fueling. What are you using to adjust fuel? If you haven't adjusted the fuel map then you'll be running really lean up top, do. Have an AFR graph?

Big Wing mentioned a problem with the fuel map right after I installed the full spec power converter. I had no speedo readings and the engine warning light was stuck on. Not sure how they adjusted it, but the speedo is back and the warning light hasn't come on since. I'll ask them about a AFR graph next time I go there.

First time on a liter bike. Nice Vid.

Here is the final dyno for my bike. 99.40 N-M converts to 73.3 ft lb, which is pretty close to the 77.24 ft lb that Motorcycle U.S.A gave it.

Motorcycle U.S.A. has max HP at only 151.27 which must be at the rear wheel.

For the Akrapovic Exhaust, full size velocity stacks, K&N filter, and full spec power converter it was about 50,000 baht.

Just an update, if anyone is interested. My bike is now derestricted. It has been confirmed by Big Wing's Dyno, but the numbers seem a bit low. It is now putting out 131.49 hp at the rear wheel and 99.40 N-M for torque. I may try another dyno at Dirt Shop, but I am very happy with the bike as is. Restricted it would cut out at 100 HP @7,500 RPM. It would also lock top speed at 190. The dyno also confirmed that it is now capable of doing just under 300 KPH. I got it up to 204 KPH on a recent trip up to Kao Yai. What a feeling.

The full spec power converter piggyback I put on is pretty cool, as it allows you to program in the amount of teeth if you make sprocket changes. It also allows you to program in three different adjustments for the electronic steering damper.

It is good luck when you buy a new vehicle to buy a lottery number with the same numbers as your license plate.

You had good luck today.

My plate number came out in the lottery the day I got it. Didn't play it though. dam_n!

I looked at the cbr1000 too. Its going to get taxed also which could put it in the 900k range. In its thai/restricted form it doesnt really have any more power then the z1000. I am getting older and for daily use and comfort the z1000 wins hands down.

The tax probably wouldnt have stopped me as i wanted a legal bike. I ordered it before the motorexpo and it was here in less then a month.

The CBR 1000 is easy enough to derestrict with an aftermarket exhaust, full spec velocity stacks, and an ECM piggyback. It is pricey though and it will be interesting to see if it gets the 10 or 20 percent tax.

I rode a 500R up and down the Bigwing car park in CM. Very similar feel to the CBR250 - a bit toy-like in the lightness of controls, lightweight enough for traffic. Much more zoom than the 250, which makes it a potential fun bike for weekends, and it seems on paper enough power for decent long- range touring through mountains. Sound is subdued, not unpleasant. Riding position feels slightly more upright than 250, and the F is more so (and the X even more when it comes in Feb/March). Seat may be ok for lighter riders, but XL riders and above will probably want some more padding.

I don't like the looks so much - lots of plastic, and that wide open rear end that throws water onto pillions (and demands ingenuity for mounting luggage systems).

I don't see it becoming a classic for collectors 20 or 30 years from now. Doesn't have the "x" factor of its bigger brethren - the 600 and 1000 cc machines. Overall, I think it will be a very practical bike for everyday out-of-town use, although a run to Mae Hong Son would be a better test than a dawdle in the car park.

I took it for a spin at Big Wing Bangkok yesterday. Same thing though. The test ride area wasn't big enough to really get a feel for the bike.

Si Sawat in Kanjanaburi is a good alternative to Kao Yai.

I rode through Kao Yai today with a couple of friends. No mention of a ban. Perhaps after New Year, but I can't see it being in effect for long. This obviously hasn't been thought through.
