My Tuned R15

fieroid · 26th May 2009, 15:58

Its my 7 months old R15 with 12000kms on the odo and not stock anymore. Completed a performance build about 2 days ago.
Here are a few specs of the bike as of now. The specs are always due for changes as and when I desire.
This is purely a street build and not a race build. key is reliability, economy and rideability. All works are done by me.

Engine:
*Ported and polished cylinder head with altered port geometry
*Custom valve springs
*Stock Valve sizes
*Reprofiled valve seat area
*Stage 1 spec camshaft with custom ground profile
*High compression set-up
*Modified cylinder and stock piston
*Fine tuning and set-up corrections
*Stock airbox and filter
*Stock throttle body and intake tract

Fuelling:
*Stock Injector
*Stock ECU + coil
*Altered AFR values for fuelling inputs

Gearing:
*Stock sprockets
*Stock Gearbox
*Stock Clutch

External:
*Stock looks
*Hand crafted Tuned Free Flow exhaust
*Full stock weight, no lightening

Performance:
0-60 – (awaiting tests)
0-100 - (awaiting tests)
Top-speed – 140kmph (As tested on 24/15/2009 on GPS and Speedgun, with rev-limiter cutting off speeds @ 10000rpm) with full stock mass.

The engine has higher low-end torque than a stock R15 untill 5000rpm and from then on, it gets into the powerband with a stronger pulse. The engine is very streetable and reliability is as much as stock. After being thrashed for over 200kms last afternoon and being pushing to top-speeds numerous times as part of my destructive tests, there was not a hitch in performance or engine NVH levels. The engine stills returns decent fuel efficiency for the power it generates. It’s approximately around 30-35kmpl.
Sunday, when I tested the bike, a stock R15 would clock 119 to a max of 125kmph on a hopelessly windy road (with multiple efforts) and at the same point my R15 clocked 131-138kmph. And recorded a max of 140kmph on a clear patch, with the rev-limiter kicking in @ 10000rpm.
I will also do a Dyno run and post results here.
Will post the pics a while later.

A small video of the exhaust note and the rpm climbing.

Your answers,

The FID is an import. Its to rework fuelling and diagnoise Yamaha FI engines.

It took about 700-800mtrs to clock the 140kmph mark.
Does about 121kmph in 400mtrs. Stock does 112.
I have done the entire works myself.

nice work there Joel, thats a good grunt from the exhaust, a lot lot better than girly stock exhaust...
since Joel is a both a very good rider & a tuner i trust his work more than the other self acclaimed garage tuners....
hopefully someday u will take up some mod works on my YAMAHA GLADI....

Looks good, any plans to change the rear rubber. As the stock seems be outfit for this baby.

fieroid · 26th May 2009, 18:44

^The stock rubber can do a lot more than what you can imagine

no dude you need to put the FZ 140 rear because it's uber cool! j/k!

2StrokeJunkie · 26th May 2009, 20:35

yea the R15 has got mind blowing cycle parts ... sorta like a TZ but with lesser power . infact even the other yamaha entry the Fz has got excessive cycle parts for its puny engine .

great work joel . i never knew u used to tune . heard u used to go the zen and then shankar .
