Re: Swingarm chain guide
I've replaced mine unnecessarily so you can have the old one if I can still find it. I think I bought mine from the local Honda dealer. It did involve removing the swingarm but it's not such a big deal. To be honest I'd recomment it as it gives you a chance to grease the linkages which made a huge difference to my bike - it had about 32k miles on the clock at the time.
How many miles have you done on your new chain/sprocket? My experience is that the chain takes a while to fully "mesh" with the sprocket. You could cut away some of the rubber damping (I'm assuming you have a OE Honda item) of the front sprocket.
