Hi Matey.Can i suggest you try using 3 new springs & 3 old springs in a Triangle formation, this will give you more spring pressure than 6 old springs but won't be as heavy as 6 new heavy duty springs... (An old racing trick) to find enough spring pressure without clutch slip at high RPM with the bonus of a lighter clutch lever feel.Regarding drilling the basket for better oil flow, this is a free Mod that actually works wonders on any wet multi-plate clutch.Personally I drill all my clutch baskets, I've found it works well if you get a marker pen & mark the location of the steels on the basket, then drill 3mm holes in these areas, I stagger my drilling in a spiral type pattern & slightly countersink all holes drilled, this massively improves oil flow throughout the plates & I've yet to see a dry plate after this Mod.Hope this suggestion helps?
I saw an American site where they cut a small trough from the existing holes in the back plate up to the lip around the edge of the plate. Looks easy and was going to do that as well.Old trick used on a few bikes including the old fzrhttp://www.factorypro.com/tech/clutch_y.htmlThat's the site I saw it on. It does look quite easy to do.

Can anybody tell if the pin (with the notch at the top) that you see when you take the clutch cover off, the one held by the cover that is bolted in with the six screws and clutch springs, should be tight in its hole?Mine was very sloppy and whilst I thought it cant be right I refitted it and the bike broke down on the way to work. There is not enough movement of the lever the cable connects to on top of the clutch housing and I wonder if the pin has moved to one side. Thanks

Well, carried out the clutch basket mod. I drilled an extra 2 holes on the side of the basket so I now have three sets of 2 rather than the original 2 sets of 2. I also drilled another hole through the back and went up a drill size on the existing holes. I also countersank the holes of the back.The hardest part was bending the locking snib back to secure the main nut, It took almost 30 minutes but its done now. I'll try it out tomorrow.
