Okay thanks for all the responses guys, sorry I took so long to get back.
I did a bit of reading, that helped a lot. Messed around with the clutch rods a bit, that didn't seem to do anything. I just bought some new springs that I'm planning to put in.
When I bought the bike it came with a whole (used I'm assuming) clutch. I've just gone through cleaning them as Oldfeller suggested, (they're just soaking in oil now) and I'm planning on swapping those in.
Problem is: I just went to take off the clutch nut, and I was able to take it off just by applying the front brake and twisting it off with pliers. Seems to me it should be a bit tighter than that! Anyone have a suggestion on HOW tight I should retighten it?
Oh and the oil I'm running: castrol 4T 4 stroke SAE 10W-40, and I was also using up some GN4 4 stroke SAE 10W-40
