Ok so i started the 01 sks 700 up the other day and noticed a chirp-chirp coming from what appeared to be the chaincase. putting it in reverse changed the tone some so i am thinking possible bearing? Anyway, i was wondering how hard is it to remove the chaincase when you have reverse. I have done it several times on a non reverse machine. I just want to know what im getting myself into before i tear into it. i would proble just replace all the drive bearings as long as im in there so then i know all bearings are new and dont have to tear it open again. thanks for any info!!
