and then a little bit more.
Yay for 4k's.

No factory limiter, stock redline is 6k.

How long do you want it to last?
5000 is/should be fine

my old 4k struggled to get anywhere near 6k, anything after 4500 it just made a terrible noise and didnt go any faster.

if you wont one make one

get a ricer tacho with a shift light, put a closed relay between you coil main power, and use the shift lite power as the tricker for the relay to open, so you set your ricer tacho to 6 grand, so when it hits 6 grand the power is cut to the coil and the revs drop, tacho drops light goes out relay closes, coil gets power and bam until you hit 6 grand again

^^^^ I have exactly what KE slider is talking about on my car (4k kesev), works a treat, free adjustable rev limiter for a carby car.

Need to get a vid up of how it sounds too, a hole in the exhaust and when it bounces off the limiter people around get SO confused.
