Just wondering how often I should change exhaust packing.

Opinion varies, depends who you ask. In my opinion every 6-10 trials, you can usually tell when it needs done by the harsher sound. Its cheap to do, and does smooth the power, although can be a right pain with the newer style plastic endcaps

If I go insane and ride 200 hours in a season, I might do it at the end of the year. Otherwise, I'd bother maybe once every 2 or 3. Pulling a bike apart when it doesn't need to be is about as useful as never doing any maintenance at all.

In that case your bike must sound like an old motocrosser and not run very well. Its hardly pulling a bike apart, its 5 screws, costs a fiver, and can be done in less than an hour.

Your last sentence defies logic

Some things warrant regular attention, others you can wait and fix it when there's a problem ... apart from being a bit noisy I'm skeptical as to whether there's any noticeable difference between an exhaust that's been freshened up once a year and one that gets pulled apart every month.

This topic has, at least, reminded me that I should do my exhaust sometime soon, though :)

Luckily the manual actually tells you that every 5-6 trials (unless you happen to ride 20 hours at each one) is a bit ridiculous.

Every 100 hours must be about 30+ trials at least.

Or 20 sessions of 5 hours riding ... which can happen easily enough

Or, if you mess your premix up really badly, 1 session of 30 minutes :P

The maintenance manual also says to replace the cylinder and cylinder head every year. Do you follow their guidelines on that too?
