Im thinking of putting on a big bore kit to a XT660 but there dont seem to be that many. Although there seem to be alot of parts for a raptor, which according to my knowledge, should have the same engine.
So from what years of a raptor 660/700 can i take cylinder sleeve and piston from? Would it be bolt on or would i have to change more parts?
How much would a 686cc sleeve and a 11:1 comp piston affect the durability of the bike? Would it still be a bike that you could use in daily or would the extra cc and higher compression be to much for the engine?
Thanks in advance for the help
