250R rebuld

Do you guys think I should rebuild my 86 R if it still runs good but lacks a lot of power. I dont if it is worth the money if the thing runs good. Any suggestions would be good.
Thanks

If it ain't broke don't fix it.

do a compression test on the cylinder and get back to us.. if its low and you dont do somethg about it... may cause you lots of problems down the road...
