somke at high RPMs

[midnightsliding]

well i have a stock KA, with 2 91 exhuast valves, removed secondary butterfly valves, and some other lil things, but i noticed the other night on back roads, i got on it in first gear leave this gas station, and it pulled untill around 4500RPMs and it felt like it hesatated and i ssaw it smokeing from the exhaust, and seconds gear did the same at 4500 rpms, but other gears are fine, and driveing it around it dont smoke, untill i floor it in first or secind? what could it be?could bad gas cause it or what, b/c it didnt do it untill i got 93octaine from this shaddy gas station!

well run the gas out and refill to make sure it wasnt the gas. Probably is, i have gotten some bad gas from places, poor burning and some smoke.

[midnightsliding]

yeah , i think it is the gas too, or at least i hope so, thanks

you might look for a product at the parts store that helps clean up bad fuel. Not sure if any are specisic to a particular contaminant in fuel(ie water) but you may look into this. It might help pass the fuel through better.

bad gasket maybe?

[midnightsliding]

[phatmax95]

oh what was it then, dont know?

[midnightsliding]

not sure i think it too much backroad driving, too much high RPM driving i dunno, i thought it might of been bad gas, but it still dose it what ever, ill fix it soon or later
