yep more pull from idle to midrange, the hotcams take care of the top end but i never use it anyways.
the most suprising aspect of the bigbore kit is that it makes the bike easier to ride.
now lets see if i can get the drill to spin the wheel to 150! :D

I reckon I'll vouch for 150 on a WR, a 426 kept my 610 pretty honest on a low level flying excercise (controlled conditions, closed course, professional rider etc...) ;) LOL

cylinderworks kit cost me $509 delivered with spare gasket set (from usmotoman ebay usa exchange rate was 107 at the time)
comes with
new cylinder
cometic gasket kit
vertex piston kit

was a bolt up job no modifications required and looks standard from the outside (still has 449cc stamped in it) I assembled the motor my self it is no different to doing a standard piston change I am unsure as to how durable this kit will be as in the states some people have had issues with these kits however most problems seem to arise when they use ultra high compression pistons(14:1) and in atv's
if you can change a piston you can fit this kit

jetting wise i have
48 pilot
45 leak jet
168 main
gddsq needle 3rd from top
bike also has stage one hotcams
dep s7 exhaust

i feel the kit is worth doing if you trailride as i do cause you dont have to flog the engine as hard
standard the wr450 power is too user friendly for me
this kit kinda brings the engine out of it's COMA
if your ever down this way riding Hori (like at the urbenville ride coming up) your more than welcome to take her for a spin so you can then compare for yourself the difference (but i guarantee you will then want one)
spambo out :wave
