Hehe! Way to go!!! Joel! The bike's doing great man! maxing out in 700mts is just awesome! Yamaha has gone bonkers with its prices and claims w.r.t racing kits. I'm glad your here to quote the statistics as is!

Makes my decison of getting a p220 even easier. The FZ is great in the city and a great steed to learn the finer aspects of riding, and the p220 for my speed and touring needs. I hope to be a really skilled rider by the time I have the money for a p220.

Why doesn't Yamaha charge us Rs. 1.50 lakh flat and give us a road legal showroom fresh 200+ cc or still better a 250 cc engine(even if it is kept a little bit detuned and civilised) in R-15 chasis and all other things being equal.

This fiddling with a bone stock new engine with the bits costing close to Rs. 1.60 lakh is insaneness.

Yep - she does sound really loud

The kitted R15 has the following advantages over mine in terms of equipment levels,
1. Higher ignition cut-off to nealy 13k
2. Gearing change to shorter ratio
3. Lighter sprokets which reduces drag

If you see the 0-60 times and 0-100 times of the kitted R15, it clearly points that the difference is mainly only coz of the revised gearing. These bikes were running a 13/42 set-up over stock 14/42 which I run.
If these Kitted R15s ran the 14/42, the 0-60 time wont be any great over the stock.
Any engine with good power will show its might in the 0-100 time, coz as you shift higher gears, the load on the engine increases. These kitted R15s have a drop in momentum past 60kph from the tests and only the shorter gearing gave that 0-60 sprint. Its still half a second slower than mine to 60kph and if I ran the shorter gearing, it would have done a flat 3 secs.
Another thing to notice why the kitted R15 is making lesser power is, just notice the 100-110kph figure.
0-100 - 10.67sec
0-110 - 13.67sec
Why would a souped up engine need 3 secs to do just 10kph more? It could do atleast 15-20kph more in 3 secs. At 13 secs, my R15 does over 120kph and closes a 400mtrs dash in 16.3secs registering 131kph(speedo - 136/137) on the device. All this, I'm repeating with stock gearing and a stock 10000rpm cut-off ECU.

I'm only wondering how Yamaha can claim wrong numbers and fool the crowd. Nobody is gonna question Yamaha and they are still gonna sell these kits to a lot of bakras and make good money. Very frankly, from the looks of the performance, these engines are hardly making 3bhp over stock - Hardly! We can prove on a dyno too.
I'll prove I'm making 2bhp atleast over them with the stock ignition and stuffs. Is Yamaha game? It'll be sure some super fun

Ok, let's just forget about yamaha's kit... When are your hand made kit coming out for us ?

PS: the only issue that i see with your mod is the idealing of engine... I hope you come out with the solution/ or did you already ??

Hehe! Joel you said it!!

Sad that Yamaha with all its tech are offering us a gimmick. And the way these SS guys advertise these specifications have these poor R15 owners jumping with joy.

Isnt the R15 geared short already? Yamaha's 'mod' will make it peak out sooner in the first 4-5 gears. Good only for the tracks but maybe with its higher rev range may offset the shorter gearing?. But what's the point of revving any higher if the engine doesnt build any more usable power?

The difference from 100-110 for 'yamamod' is 'big'. And it only gets worse from there. How can they even make claims of it getting to 150kph . I wonder if it would peak out in the top gear at this rate, or have any power to get there at all.

When i look at the stuff they are selling, it makes me wonder if there's any thing worth in the entire kit at all! Well nothing's worth in it! Another money making scheme at the cost of fooling customers.

Are these figures claimed by Yamaha!!

C'mon dude...we are waiting for your stuffs. When can we have it...

better start a performance store or else we'll kill you asking the same Q again and again

Heya Bunny how good is the racekitted FZ to the stock bike and one more thing what is the cost of the full racekit for the FZ?

Heya Joel will a Race CDI help FZ to rev more? And will these revs help to produce more power or it will be just like the R15 a high cutoff.

New video on You Tube-R15 daytona

Guys

found this today morning -

YouTube - YAMAHA YZF-R15 reached 150km/h


Hmmmm

I guess you meant "idling".
That can also be sorted, but remember an aggressive cam profile will always cause varying engine idle and I have already found a solution. The stock ECU cant fuel rightly to make the engine idle normal and hence this.
The Yamaha kit runs a very mild cam and hence, it will idle like a stock engine.

Joel

Awesome video there mate, really good find, i wonder what joel has to comment on that??

Very crisp and ulta quality of video, looking at the video the claims & marketting these guys are doing , i feel the kitted machine definately has more potential than the stock, it's reving more freely just see how fast it touches 12K ****

joel please comment on the above video...what's ur take on it

^^ shadow ..tht's ok but just look investment vs output man.

55k for such a low bump ain't worth it ....if stock can do 148 on speedo albeit with a little struggle though...
