Thanks for everybody about comments.
Just wanna continue little bit talk about the my issue.
Pages from www.wiseco-europe.com I found following information.
There is new kit, model CK172. That its for america models -02-05.
Price here in Finland is 600,00 euros.
Bore x stroke is 47mm x 74,35mm. What else i had to change in motor. (Ghostrider answer was: "Including getting the crank reground, getting the juggs bored and sleeved. I would recomend getting bigger carbs to, that is a big piston"..)
What crank reground means? (I didn't find it from dictionary)
Do the stroke getlonger? If compare orginal? Do i need longer connection rods?
At the end, does enyone has been done it? Is it worth of it ?
