Re: Spark plugs?
This topic has been bantered around here too many times to count. Basically there are two ways to access the plugs. You can lower the radiator and get to them from the front like the manual says, or you can remove the tank and air box and get to them from the top. If you ask 10 people on this board, 5 will say it's easier from the top and 5 will say from the front. It's really your call.
For me, I've decided to replace my plugs every 16k miles, which is double what the service manual recomends, but 16k miles cooresponds to valve clearance inspections, so it only makes sense for me to access them from the top since I'm already there doing the valve inspections.
As for the tool, you will need the spark plug tool that comes in the tool kit. Either that or you'll have to find a really thin wall spark plug socket, and maybe a U-joing on top of it. I'd try fairly hard to find that stock tool. There's a frame member that sits right above the spark plug holes, and they're very small, deep holes.
