danno, you will get more pleasure out of your bike if you learn a little more about it. There are several books and the spare parts list available from the Spares Company. When you look in the small inspection cap you will see the top of the actuating lever, the end of the cable with nipple and the spring. The push rod is operated by the lever and touches it near the bottom. I don't have one to hand to give you exact measurements but roughtly three quarters of an inch from the bottom is the contact point for the push rod and the lever is, say, six inches long. Just put your finger inside the inspection cap and try to push to top of the lever inwards and outwards. Does it move? If not then there is no clearance between the actuating lever and the clutch push rod. If it moves in and out, say, a tenth of an inch then there is clearance and you have to look elsewhere for your problem, probably oil contamination. From the above I suspect that you will not feel competent to service the clutch itself. That means finding help locally or paying someone to do it. The full instructions for all the work involved are in several of the books and, once again, I urge you to get them and read up what you need to do. If I can learn how to do it then so can anyone else.
