Well you are going to have to re-sleeve the cylinder to accept the larger piston. The piston that you are going to need is an 80mm if I remember correctly. With that its a good idea to go ahead and throw a good exhaust system on there and a good intake and get the carb re-jetted. Since you are going to have the top-end opened up you may also want to consider throwing in a mild cam, that is always a nice extra. Well I hope this helps, Good Luck..

 

well i dont think i got money for the exhaust and the cam...will i feel any diffrence? with only uni filter?...

 

Well if you don't play around in the water I would just drop the uni filter in and run without an airbox lid. Remove the baffle from the exhaust if that is permitted in your area. You are still going to have to re-jet doing this. Going with the big bore you are going to want the engine breathing better and yes you will notice a difference.

 

well, i also need a new clutch :\ and the guy who install all the stuff want alot of money [img]i/expressions/face-icon-small-smile.gif[/img] thats the way in israel everything cost alot
i will consider the exhaust (HMF is the best for EX ?) and how do i remove the baffle? in case i wont be able to get the HMF or whatever you say that good[img]i/expressions/face-icon-small-smile.gif[/img]
