99 RMK 700 136

Hey Guys... Im looking for info on 99-01 700 RMKs... i own a newer 2012 600 rmk.. i am looking at picking up a mod sled. Something for a backup and fun sled.. Currently just purchased a very clean 99 RMK with a newer 136x2 track. It has the full seat/gas tank combo. Could i fit a Edge or gen 2 tank on there so i could use a edge shorty seat? I am looking at doing a skinz or wrp shorty seat. I also will be doing a wildchild steering post and risers. Anything i should look out for? Compression is good.. current mileage is 4100. Never had the top end or clutch rebuilt. So i might be doing that this summer time.

Any and all information would be very helpful.

Thank you
Chris
