on the UK forum a guy posted his compression readings and thought he had a looming problem, I'll quote:
"Firstly can I say I'm a total novice mechanic.
I was concerned that my 1300 Super was hesitant below 2000 revs. I decided to run a compression test and the results were not good.
I have to admit that I didn't warm up the engine, did not touch the throttle during the test and the test was dry. is it worth re-testing..."
I told him his readings meant nothing and to retest 'HOT, WOT and all plugs out':
then he got (quote):
"I have a new set of compression results from a warm engine, throttle open . I'm pleased to say the numbers are completely different to cold engine throttle closed.
1) Dry: 195 Wet: 200
2) Dry: 195 Wet: 200
3) Dry: 190 Wet: 190
4) Dry: 195 Wet: 205 "
he was a pretty happy bunny and could now concentrate on the next problem
