I'm baffled as to why anybody needs anything other than pliers (or good quality pipe wrench) to remove and refit the spring clip, but anyway each to their own.
However, a thought occurred to me today.
A few years ago I (as it turned out needlessly) replaced the drive chain on my Yamaha TR1 ( known as XV920 in the U.S.). For anyone who isn't familiar these bikes, they have a fully enclosed grease filled chaincase (much like the Norton Rotaries and MZ's) only much harder to work on as the chain is a whopping 630 !! and you can only pull the lower boot back about 2 inches. After a struggle I got the new chain threaded through and eventually after using twisted bailing wire to bring the ends together got the joining link in and the outer plate on. But I could not get the spring clip on for all the begging and cursing I could muster. I eventually took the joining link back out and measured the width of the inner plates, then on the joining link the distance from the inside of the outer plate to the bottom of the clip groove. I found it was a few thou short. At first I thought the plate under the clip must be too thick, then I got out my magnifyers and could see that the pins were a bit proud the the outer plate. I put the link in my vice, pins downwards, closed the jaws until they were just touching the pins, gave each pin a single blow with a hammer then measured again - perfect. I had the bike buttoned up 15 minutes later, after much scrubbing my hands, free of grease an hour later and the backache subsided around 3 days later!!
So anyway, Maylar, if you haven't managed to get the clip fitted yet it may be worth checking that there is enough exposed groove to actually get the clip into.
Cheers,
cliffa.
