Now, i bough the hrc jet suggestions and i am ready to install them and test it.I will leave the power jets as they are just to be secured.

You are fighting a losing battle if you don't fit the kit (or anything else for that matter) as HRC intended.

I've seen it dozens of times. If you don't fit all the kit and set it up as it's supposed to be, then it simply doesn't work. As Kieran says, 1st and 2nd aren't a good way to tell what's going on, as the motor is in the high RPM zone for a lot shorter period of time, and under a lot less load. You should be confident the motor is free from air leaks and a little rich, and then do a plug chop in top gear. Either that or take it to a dyno where they know NSR's and how to set up an HRC kit.

As stated in the tuning guide, the HRC base settings are NOT to be considered as the definitive setting. They are for use with (amongst other things) pre-mix, HRC race pipes, HRC heads, and open carbs, and under the same atmospheric conditions as stated in the HRC manuals. They are also only base settings for SP and SS applications, which both allow tuning of the engine internals to a different level, which can also effect the jetting requirements.
