I'm going to look at a R1100RT-Police that the seller says needs a clutch. I've put clutches in airheads, but not these newfangled bikes. Is this a straightforward DIY thing, or am I about to bite off more than I can chew? On a scale of 1-10, my mechanics skills are a solid 4-minus, but I'm pretty game to try things. Also...what might I be looking at in parts cost for this job (I assume, besides clutch, I would do the rear seal and other maintenance while I'm in there...?) Any other tips greatly appreciated. Thanks!
