well i finally diagnosed my high rpm hesitation, today i set my afm to richen the fuel mixture all the way through the power band by adjusting the little gear under the black cover, my hesitation got worse and startted at about 5800 instead of 6500rpm, so now i know im running too rich up top, i need an S-AFC NOW lol, i gotta fix that, gonna replace the coils and get new fuel injectors and an S-AFC, so maybe it will be gone by then


edit: forgot that it could be not a good enough spark up top, and does anyone know any ways to lean out the mixture up there??

 

so first you were runnin to lean and now too rich?

I have a hesitatil at 5500rpm and above and my fuel screw thingy didnt help
