If the bike runs OK on idle, then you may be lucky. They can hang on to revs or hunt on idle if the centre seal is bad, and also be a pig to start, but often run fine through the gears once started. But various conspicuous idling issues almost always gives it away.

To be fair, I've never had an infra red gun on NSR barrels, but a 40° difference is rather significant!

A rebuilt crank is about £500 if the crank passes [a £25] assessment (most do, but some do not). I believe GTPE have brand new cranks in stock for about £650.

I've not worked there for 18 months now, so best to get in touch to double-check prices and lead times. Please tell them you were referred by NSR-WORLD if you contact them.
