pulse adrenaline bogging out at 8000 rpm

[Dan SM]

So when you say bogging you mean the revs aren't going past 8000? Bogging is caused by too much fuel and not enough air in the mixture. I assume you can walk the throttle open wide and there is also no bogging until 8000? How about in neutral? The same?

I recommend turning the air and mixture screw fully in and then screwing it out about 1.5 turns. See how it runs. My bet would be the needle pin or maybe the needle itself. Infact, what's the colour of your spark plug? Black is rich, white is lean. It should be a nice brown colour.

Anyway, I'll stop rattling on. I recommend dropping the main jet a size and see if it improves, let me know how you get on. If not, get the thing on the dyno, that way it can be set up properly. Josh

i just realized if i pull the throttle back slowly it goes past 8000 rpm just like normal but if i pull it back abit to quick it bogs out at 8000 rpm and doesn't go past it and yes its doing this in neutral is this a sign of too much fuel and its flooding? i just checked the spark plug and it was black but i didn't do a plug chop but i cleaned it there and put it back in and left it running awhile and theres no black looks the same as when i cleaned and put it in altho theres was a slight bit of liquid on it im assuming its petrol but didnt smell to strong of petrol i tried the needle but i'm open to try anything so i will try it again where do you recommend to put it it only has 3 notches for the circlip its in middle atm ? i will try screwing the fuel screw fully in then out 1.5 as you suggested and i'll let you know how it goes thanks.
