Funny Noises

Just today I've noticed an odd noise with my '99 750ss. Here's the scenario:

- My bike had been standing for about 4 days. Last time I rode it was last Thursday evening.
- This morning the battery was nearly dead. Bike would turn over but not fire. I needed to roll start it.
- On the way to work started to notice an odd "noise". The only way I can describe it is a "clack" and a "hiss".
- On the way home from work this evening the noise started getting lowder.
- Noticed the bike felt to be underpowered on the ride home this evening
- Noticed that on the overrun, when using the engine for breaking down through the gears, that there were a lot of "pops" like mini backfires. This has sometimes happened in the past, but not constantly.
- At idle the noise is not appreciable, but anything about 2k revs it is noticeable.

I had a bit of a look around the bike when I got home tonight. It's a half faired version so access to the engine is easy enough. I couldn't see much really.

I know it's not much of a description, but any ideas?

Just booked a service today so it'll get sorted out in a couple of weeks. But am I terminal? Should I be riding it at all over the next couple of weeks?

Thoughts appreciated.

Cheers
Phill
