Yeah... 60-90mph comes up in a stupid rush...

Three figures comes up very quickly. 

Great fun, addictive too.

Don't they all do this anyway? I mean, surely yours doesn't just do it now you've tweaked it a bit?

The K75 final drive will also work, if its a 20 spline shaft, if not you need a shaft as well.

A standard K100 feels like a bit of a slug compared to the mildly-tweaked version. I tried my two back-to-back and Brick2 felt like it was going nowhere compared to LFB. The tweak seems to put much more in the midrange where it's really needed.

Having done the 1100tbs and the timing tweak , there was a definite increase in mid range response.

The other change I did was to adjust the TPS as far retarded as I could to stop the fuel being cut off at lows revs, 

which meant that the second trigger should occur a little sooner on the throttle opening than with the standard TPS set up.

I would not normally drop her two gears and wind her open, thats not my usual style of riding, usually relying on roll on power , which is also good.

I did it once before the tweaks and wasnt overly impressed, but now she pulls really well.

So for me, the three tweaks have combined to make difference.

I will still ride like an old fart on a LT, but I now know what lies beneath if ever I want to have some fun.

If I rode an RS , I probably would be tempted to open her up more often.

I've heard of this tweak, does it work for the K75 engine?  Would like to tweak my K75's, as since riding my 16v K100RS they feel a bit heavier than the K100.

Apparently hitting the starter button is also supposed to give you a bit of a boost. It enriches the mixture, I haven't tried it, I just drop a couple of gears. However I experienced a definite improvement by cleaning all my injectors and getting the correct spray pattern.

Then you first must select neutral, or pull the clutch.

The 4° advance works well on any of the bricks. The base idle timing is left at 6° BTDC because if it is advanced any further than that the engines don't pass the pollution tests.
Unfortunately most engines are being made now days that they cant be advanced any further because the trigger mechanism cant be moved.
With the North American model 8V engines if you really want some bottom end torque then advance the inlet cam a tooth (10.5°) however you will miss out a bit in the top end HP department.
 Same can be done for the North American and Australian model K1100 16V but not the K100 16V engines.
Or buy a set of 16V cams from Europe which open the inlet 20° earlier and will still give you good top end.
