righto guys, how can I lift or remove the speed limiter on my twin cam?

It has S&S slip ons, screaming eagle tuner, 211 cams.

Pulls like a freight train, but stops dead at 180ks.

I know, I know, why the fuk would you want to ride at those speeds.

Why the fuk not, I ask.

1. It should go past that kph, unless it's geared down?
2. No speed limiter on them
3. They have rev limiter, set at from memory 5500rpm standard, often can be increased with your tuner to say 6200.

Pretty hard to hit the rev limiter  in top with a six speed box

Mine at over 220 kph doesn't sound or feel close to its rev limit (I don't have a tacho) even when it was at 96 ci

Ok, I've never heard that before.
What speed are they limited to Steve? Must be pretty high

Well definitely sounds like it limited.... Someone will come up with an answer for you, I sure as hell don't know lol

Your bikes doing well to hit 180 in 4th though,

mine (when it was at 96) used to hit the 6200rpm rev limit in 4th at 172

and mine is (slightly) taller geared than stock with the 18" rear wheel.

Goes way past it though in 5th and 6th

Good luck mate, I'd be pissed off limited to 180 ha ha

My bike goes off the clock in fifth, but wont go to the rev limiter in sixth. I'm suspecting it maybe speed limited as well because it's acceleration seems to drop off suddenly. Rather than gradually as is my experience normally when a car or bike engine does it through lack of power.. My bike seems to handle fine at these speeds us less wind is gusty because I have a screen on it, that makes the bars shake a little. Either way shit loads of fun. Oh and I only do it on a track.
