be careful with the cx, I had one les than5 years old and they suffered from big end failures, I test rode mine , agreed subject to a rattle on left side. turned out the garage had to replace big ends, rods, and pistons. even back in the day with a Honda trained mechanic it was a all day job to get the engine out.
as for clutch slipping, what oil was used for last service? many people used oil designed for cars, this made clutches slip on bikes... hint, bikes run wet clutches cars run dry!!
as Arek says, when were plates and springs changed. EBC do higher tension spring kits
