How difficult is it to replace the cam chain tensioner

Last year I had a mechanic do a valve adjustment for me. One thing he mentioned to me was to see if I could replace my tensioners becasue the one on the front cyl. was not working properly. He took it out and told me the spring was pooched.
So, I won some off e-bay and am wondering if this is something I could do or should I have a "pro" look into swapping these for me.

How difficult is it?
If anyone knows of any good links would they mind posting them up here.

Thanks in advance,

If you can borrow a small third hand, it would be easyer!
1 to hold the screw driver,keeping it wound up,
1 to put it in place,and a small hand to start the bolts :) It's not rocket science.
It's doable... There's a tool that you can make. I used a large fender washer. Remember...if you do them yourself...all of the screws can strip...EASLILY....
You can do it yourself. The front is much easier to replace than the rear because there's more room. You have to prop the tank up, take the airbox off and possibly the carbs to get to the front cct. Next, undo the cap bolt and get a small screwdriver to keep the tensioner "unwound" while you undo the two bolts holding the the old tensioner. You may have to buy a new gasket depending on if you can salvage the old one.
If you are going to replace it yourself, you MUST make sure that the cams are positioned such that they are NOT depressing any of the valves. TDC on compression for whichever cylinder you are working on. If you remove the tensioner while the cams are depressing the valves, they could ( will ) lurch out of position from the spring pressure. If that happens, you had better bring it to a mechanic because if you messed up the tensioner you won't be able to fix the cam timing.
