XT660 vs Raptor, which parts will fit?

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

Thanks. Found some answers.

But i also have some more questions. Does the raptor 660 share the exact same cylinder as the xt660? Is it possible to use a cylinder head from a raptor 660 on a xt660? If so, from what year of raptor fits the xt660 -07?

Is it possible to use a cylinder head from a raptor 660 on a xt660 I have seen a Raptor 660 5V head fitted to a Raptor 700 motor with modifications done to the head to make it fit? If so, from what year of raptor fits the xt660 -07 Why would want to fit a 5V head, it is proven fact you can get more HP out of a 4V head.

the HYBRIDS that have been done use a Raptor 660(5v) cases while using a Raptor 700 (4v) cylinder and head
The raptor 700 cylinder has to be modified slightly to fit (the 6mm screw holes need to be offset by 2 mm.)

My recommendations for a big bore conversion would be to run a OEM RAPTOR 700 cylinder and your choice of either OEM piston or 11:1 CP. If you decide to run the OEM cylinder id recommend to mill the cylinder to increase compression and tighten up deck height
