[Kwee]

/!\ That's not my bike, i'm just sharing results and informations.

Hi everyone,

My local tuner tune his first H2 SX on the bench. He flash many H2 SX ECU but this one is his first on the bench.

He is impressed how the bike feel and pull. He said he enjoy a lot tuning this bike.

He said the redline is at 12250 and not at 12500 like i throught. @Vcyclenut ?

Updated : I call him back, he correct his statement, the stock redline is at 12500 rpm, he push the redline at 12700 rpm. Not so much.

He let the bike run a little rich for safety purpose. He said he can gain 3-4 hp here by leaning a little bit at high rpm. Timing is also retained a bit back for safety purpose.

Kawasaki tune the bike with conservative tuning and rich at high rpm, a little lean at low rpm. That's why the gain is so impressive.

The bike has only a slip-on, stock air filter

28 hp gain, what do you think ?

Torque gain is impressive(between 1 and 1,25 mkg) but the lambda sensor must be disconnected for get a smooth throttle.

He change the redline : 12250 -> 12650 (+400)

Updated : Corrected, he change the redline : 12500 -> 12700(+200)

he just stop the bike stock because the bike not making power at stock past 11000 rpm
