To be honest the M2 engine could have had a sensor before I bought it. The guys I bought it from might just have sold it or something... It didn't have a speedo sensor either, so I had to re-use the one from my X1 engine. And the Oil pressure sensor was buggered as well...

In terms of speed, the M2 engine is a lot smoother. probably just down to fueling and/or compression. I'm quite happy with it now. Now if the exhaust doesn't fall off again I'd be even more happier! :D

Were the early M2s carb, and the later M2s FI?

If so, the temp sensor would not be needed for a carbed variant...

The temperature sensor was incorporated on the carb'ed biks as an upgrade from (I can't remember exactly when) 99-00 bikes. It is a sensor on the rear cylinder head and came about after a spate of damaged rear cylinder/piston events. It cuts thje sparks to the rear pot if it gets too hot. The "technical upgrade" was offered to earlier bikes but was not a recall. Some bikes got retro-fitted and some didn't. The sensors weren't particularly reliable IIRC, so my '97 bike never had that particular upgrade. Again, IIRC, this was around the time when the sparkling plug spec changed from 6R12 to 10R12. There was also a modified float bowl assembly for the Keihin carb as well if my memory serves me well. I didn't do that mod either, because if the float needle passes, I'd rather the fuel runs on the floor rather than into a cylinder down an open inlet valve. I recall the modified float chamber didn't overflow to the deck.

My memory is getting a bit hazy about these things now, apologies if that isn't 100% correct. HTH.
