Thanks everyone for your prompt and informative replies...I just thought I'd be prepared incase one of those washers was damaged and I could'nt get the job done. The nearest Triumph dealer is 30 miles away, so this would mean having to put the bike off the road untill I could get over for some new replacements.
I think I'll go ahead and just do the oil change and hope that the current washers are ok. Just one more question though.......
I've noticed some folks talking about clutch slip if the correct oil is'nt used. I think this was a case of using semi synthetic as apposed fully synthetic oil. Can any you gentlemen advise me on this.
Thanks again
