I love my kawasakis, but I'm starting to have wet dreams about the new husky nuda 900... failing that I need to find some where that will allow me to put a turbosystem on finance!

Yes you could bore and replate the cylinder.

Hi,

Very interested in these, keeping a keen eye on exactly what engine work needs to be done to fit them as i obviously do not have half these tools. I'm also another who is keen to know the asking price for a set of these? im currently in the process of stripping my L9 engine down for tuning. I have a tuning and dyno company not far from me so i can get them to do it for me though..

Not sure that it's just me... but i'd be happy to buy 5 and keep one shiney new one for a display i think they look beautiful! :smt007

I don't believe these rings will work on the stock pistons.

Unless your pistons were designed to use the same rings it probably won't work. :) There's more to it than just .5mm oversize

hmmm, a big bored er6. Well, a 4 pot er6 would be about 1300 cc. The only kwak close to that is the zzr1400...

oh wait, the er6 = 83mm bore, the zzr1400 = 84mm bore. (and a 60mm vs 61mm stroke)
And the pin and pin locks are the same, which means the pistons are likely to be VERY similar (we all know how many parts kwaks share!).

And JE pistons do a 87mm bore kit on the zzr1400 piston... should be good for about 715cc!

Even a pair of stock zzr1400 pistons would give 665cc which should be sniffed at.

I might look into this!
I do 700 miles a week in all weathers including snow, that's roughly 35,000 miles a year, and some weekend warrior biker has the nerve to get out of his Audi at work to tell me to I was riding far too fast in the wet (over taking at 50... fast eh?).
