how difficult is a sprocket and chain change?
I have very little mechanical experience with my 04' bonnie, I did manage to add progressive fork springs, change the handle bars and do a couple of oil changes thus far, but now I have ordered new sprockets front and rear and a new did x-ring chain.
I would like to know in advance before the stuff arrives if there are any gotchas'
or special tools I need for a chain/sprocket job. Both sprockets are stock tooth in size but I guess I need a chain breaking/crimping tool?
The manual is all I have to go on, and it mentions that the sprockets have bendable lock washers, and that I should replace them with new ones, are these triumph oem parts that my dealer can get me or do you guys re-use the originals?
Thanks in advance!
peter.

well you will love this but to get the stock chain off you have two choices, cut it or remove the swing arm, as for the front sprocket, get a huge socket, 41mm I think. it only took about 10 min.

Peter I can help you if you'd like. I've changed my front sprocket and the rear would be no problem. You'll need a special tool for the chain though and its expensive. The chain is an endless type that needs a special tool to clamp and rivet together.

Count your blessings. I just did this on the Norton - remove outer primary cover, stator, rotor, clutch spring, clutch plates, primary drive, inner primary cover, left-hand thread sprocket nut, complete rear cush drive (with integral sprocket, then install new stuff and put all the parts back on (with numerous new seals and gaskets).
Not something I hope to do again soon. Modern bikes do have their advantages....

Motion Pro Breaker and Riviter
Here's the tool I use to break chains and to rivit the new one. It's somewhat pricy, but now that I've used it for four chain changes, it's down to about $25 per use. It appears the cost for the tool is about the same whether you buy direct from Motion Pro or from Dennis Kirk. You might want to shop around for a better price.

I found the cheaper version of the DID chain tool. Wow, does it work well, once you figure out how to use it.
Don't kid yourself, I chain needs to be done right and it is easy to screw up. A friend of mine helped me the first time and I learned later, he did it wrong.
You most certainly need the right tool. The DID breaks a chain rivet with ease and rivets a link with ease and precision so it does not bind the connecting link at all.
