NC30 Ignition Coil HT and Pulse generator readings HELP

[goose400]

Hi,
The NC30 track only bike and I track it on a regular bases. Suddenly on my last track day I got a lot of back fire and power loss when I rev it the 6K
After reading all the post I could find regarding this issue I decided to go ahead and do a full test on spark plugs, coils and connectors.
They bike starts with no problem and it will stay on 2K RPM stationary. But when I give it gas, it back fires and the rpm go all over the place after 6K

Just to be safe and it is also time, I will be doing the following:

-Carb Cleaning with an ultrasonic machine
-New carb boots.
-Spark-plugs are good ER10EH , but I will replace them with a new set just in case for testing.

My main concern are the coils and pulse generator since these are the readings I got:

Front primary winding resistance : 2.9
Rear primary winding resistance: 3.1

Front secondary winding resistance: 25.6 With plug
Rear secondary winding resistance: 24.8 With plug

Pulse generator coil resistance: White Yellow / Yellow : 408
White Blue / Blue : 413

Some of this numbers are not on the parameters based from the Haynes book. Primary 2.5 to 3.5 Secondary 14.0 to 25.0 and Pulse gen 450 to 550
My question is:
Are they off enough that will require to be changed ? The pulse generator seams to be the furthest one.

Thanks in advance

If you cannot rev clean above 5500rpm I would suspect there is an issue with the speed limiter. Are you running a speedo?

It revs pass 5500, it just does it erratically and backfiring.
My CDI is the Ignitech one, not the original.

Have you tried reloading the program.

another longshot but worth investigating to rule out.. ive had two bikes that have had issue of appearing to loose spark at high rpm.

one was caused by a failed reg/rec overvolting the electrical system

the other was a dodgy earth connection

I was thinking on doing that to see if it had any effect.

Does anybody knows if I need to replace the pulse generator with these numbers below when the recommended range by the Hynes manual is 450 to 550?
My numbers are between 408 and 413 ohms

Te numbers you have quoted for the various electrical components are not necessarily indicative of faults. The character of your problem is systemic not component, hence, Neosophist suggestion you check the battery voltage when engine revs are greater than 6000rpm. Ignitech ignitions do not run if the supply voltage exceeds 18 volts.

Thanks for the tip. I will definitely check that.
