I loaned my 372 xp to a friend, he returned it tuned from a shop, and completly detailed like a new car. He also put a new skip link chain on it. I think i will loan it to him again First thing, i have never heard of a skip link untill yesterday, then i see it in a thread in the hearth room. WHats the deal with these chains? I would think you would get more vibration. I havent tried it yet, but what should i expect?
