Thanks for your comments.
I will leave it until next year when I pull the motor for a repaint and freshen up.
I do have a new Gates belt, bought from MED in UK. All for sale here in Oz now are Chinese made. They are loose when fitted.??

I like the belt, with a Peak Ignition electronic dizzy I have NO spark scatter at all. = maybe an extra HP or two.
But I wouldn't buy a new belt setup for a road car, they are now too expensive.

I persionally think .. if you're thinking about it... Might as well do it.

  Cheap insurance to have done and replaced vs finding its failure point.. Which finding that failure point or time might be years from now.. why bother worrying about it... Belts are cheap   the job to replace is a busy one but since its a sealed cover its only cver no new oil leaks will be introduced. 

Our mini's are driven less and less over time to know the longevitiy in miles on a part, more about the wear and tear from sitting at this point. Rubber still degrades with ozone / UV / Other influences.

or you could go back to a chain and never do it again!   HA!

I fitted a new Minimania `Gates' kevlar timing belt in 2008. Their product description says `good for up to 50,000 miles' but no life time is mentioned.
After 12 years, the motor has only done maybe 10,000 miles, it's currently on historic registration in NSW Australia so is restricted use, to a max 60 days a year.

Comments re belt life? 1360 motor is running well, no oil leaks, I prefer not to disturb it. With cover off, it looks just fine.

[I did 44,000 miles with a Pirelli belt on this motor 20+ years ago, and it still looked new, no wear in the teeth covering.
I'm aware timing belts on OHC motors are only good for 50-60K miles or 10 years max, but they have an idler which flexes the belt on its back, IMO this shortens their life compared to a 52T Mini belt which has no idler.]
