Ok, Priobe- this have been into my mind as well; so: I will change air jets first and then see. If A/F is OK at wide open, and still around 10- 11 lower in the RPM scale,the exhaust has to be changed. Definitive.

I visited a racetrack last weekend and did alot of testing: In 4., the engine completely stalls at 4000 rpm, no matter what- if you gon on and off then on again; still the same. If you flloor the pedal; no answer either.
But; If revved to 7- 7500 rpm in 3., it hits 5000 or so in 4. and then it goes on (although not too far, the longest straight lets you go like 190 KMH (110- MPH), so I guess maximum 6200 in 4.?).
To be honest, the engine runs like crap, (is it weather- sick? it rained...) and I'm onto trying different things:
- Going to colder plugs
- Reducing the cold air scoop
- Removing closed "pressure box" around the carb air horns
- Using "boxed" K&N filters
(- Larger air jets and mesh filters for the air horns will go in next week)

Thanks for all the feedback
