Hey guys thanks for the add! and "NEW" to the DRRs also! so question PLEASE HELP! lol

i got a smoking deal for my lil guy! i got a 2007 drr50 that is almost brand new a lil girl ran it through water and bent the rod and broke a piston so bike was never used...
Now the question! Im brand new to these bikes and the cvt trans on them... Can a Yamaha zuma 50 complete setup engine/tranny work on the drr frame??? i found one cheap and runs perfect!
would i need to change anything in the transmission? weights, springs etc...?
Thanks guys! WOULD GREATLY APPRECIATE ANY RESPONSE ON THIS!!
