I'm sure a bunch of people have made un-detailed posts like this and it's motivated by my reasonably limited understanding of the guts of my new bikes engine so bear with me.

Over the last few weeks I seem to have developed a "rattle" in my bikes engine when idling. It's coming from the lower/middle right hand side of the engine. It's pretty consistent while idling and sounds like a "tick tick tick" as the bike turns over. If I rev up it doesn't increase in frequency in sync with the revs increasing. It seems to be slightly lagging. Unfortunately I can't hear if it's still dong it while I'm riding as it's too quiet to hear over engine/wind noise.
To my ear it sounds like a chain rattling along the inside of a metal tube. The rattle also either stops or becomes very infrequent (the odd "tic") when I put it on it's side stand.
Any ideas what might be causing this? I took it into a shop to get a tune/carb balance and they said they couldn't hear it. Tho at the time I hadn't noticed it stopped on the side stand so they might have been listening to it when it was on the stand. (I wasn't there)
If this was my original bike (a CB110
) I would just rip the engine apart and look for the problem. I have the Hayes manual for the CBR but the amount of moving parts in this engine fill me with "the fear".
I'm hoping someone here might have an idea/suggestion. I will take it to the shop regardless but it's always good to have a direction to point the mechanic so he doesn't waste time rooting around or doing un-needed stuff.
Thanks!
