Standard pistons work fine but if you're going to do this you may as well fit the Pistal high comp ones to make the most of things as the crank/rods/pistons assembly has to be re-balanced or it will shake itself to bits.

top mod..... if you want the extra grunt.

but ... to make the most of it you'll need big exhaust system, flowed heads, and on and on...


or wait 6 weeks til the new bike is out.!!!!

when you say pankle rs rods........from what bike? arnt the 999r rods pankle? do they need to be a shorter length cos of the increased stroke?

[wilf]

The R pankle rods are good but not as strong as the RS ones. (998RS rods are ideal)

You don't need a different length con rod so you can use the 999R rods, the barrell needs to be spaced up with a bigger base gasket but because the squish clearance is normally to big on the motor out of the factory it helps take up some of the extra the you are trying to lose for the extra squish.

It is a bit of mucking about with base and head gasket sizes to get compression ratio and squish correct and you may even have to have the pistons machined down.

996 rs crank on ebay £600...................

found this...http://www.youtube.com/watch?v=auEOtAsaW8M&mode=related&search= dont know if thatl work but its the carrachi 1200 sound track!

[bike mad]

sounds very much on the edge, I'd love to have a go though,
not that good on the road,? just a guess,
Is that how it was when M,C,N, had it !

[andyb]

Thing is the set up will/could be just as reliable as any ducati if not better being less stressed!

[bike mad]

yes, but it mite be a bitch if you stall it at the lights,lol
and I wonder what's the lowest rpm it will run at, it's no good trying to ride though a town with a bike that wont pull smoothly at any thing below 5'000rpm,
I know because that's one of the things I have been working on,on my bike,
I have my 999S runing a 2'000rpm in town which is a lot beter than it was when it left the factory, ps that's not the tickover just the point that it runs smoothly,
more power yes but you have to ride on the road,

[andyb]

but you have to ride on the road,


Do you..................i prefer the track!
