I see that the manual says to remove one compression ring to reduce friction.

Like the 1 ring pistons on 2 stroke machines.

This modification increase the oil burning, does any one know how much?

Is OK for road bike? (I want to made this modification)

Is for the stock Kawasaki pistons or for special ones?.

My god what a find! Something new for Baz to put up onto site no doubt!

Im guessing thats for the SP model, not the road, bikes.

Yes i think is for the SP only.

I found help the guide for inlet valves drill.

This part number must be out of production, i talk with the Greek Distributor and told me that is possible to made for only Japanese market.

The power claim 75Bhp without ram-air system

But in a few word's many guys made better bikes and more power full.

RobB your bike is an SP one?

Unfortunately its just an L model with an SP seat unit, i wish it was an SP model tho!
