Well, I delved into my first attempt at checking the tappets and before I found out that I didn't have the correct size of feeler gauge I also discovered after taking off the fuel tank that one of my throttle cables broke. Anyway, it's the one that's closest to the rider, the front cable is okay. What I was wondering is what affect this has on the motorcycle since I've been riding it pretty steadily for the past month or two. If I replace it will I notice any difference? Also, on an unrelated note is it okay to use brake cleaner on the valve covers and threads? Thanks for you help guys as always.
