Yes, I done the wire spliced, but no good to ride. feel like very weak, only the high RPM has feel.

And 132? DOWN from 140? Are you really sure it was that rich? I know all bikes are different and jet sizes are bike and condition specific but I'm going to guess you're on the edge at that anyway, running the HRC card as well is just inviting detonation.

As mentioned here there are no Honda unrestricted NSR settings the best we have are from HRC and JHA both of which are settings for no airbox, pipes, premix and without the power jets or the MMax derestricted '21 settings which are nearer what you have. They say 145 - 148 if your running the power jets and oil pump.
As for some interesting reason the Honda and HRC '28 settings are richer than '21 I'd start at around 150-152 unless I was going to buy the HRC kit. Then I'd follow Andy's jetting guide.

Thanks Andy
How about the HRC 030 card timing? will it different with Stock card, or only derestrict the top speed?
