Anyone think it's worth putting a new O2 sensor on it, see if that brings the MPG up a bit ??
I would only if I could see what the current o2 is reading. I'm not sure if tune ecu can, but I think it does read the o2. Maybe someone will be able to say. It's been a few since I've had to use tune ecu.

Tune ECU does indeed read the O2 sensor, but I'm not sure what the figures shown actually represent. They seem to fluctuate with the bike at idle. Here's a few examples taken within seconds of each other:
Any ideas ??
And...........I put the old Triumph OEM map (10172) back on the bike today and let it idle. The exhaust fumes smell like they should do ?? Very strange ??
I've been getting poor MPG lately from my 2006 955i and I've had a rich fuel / oil smell from the exhaust for years. The bike uses oil as well.
I got round to doing a compression test today, on what is a cheap and cheerful tester that I don't expect to be 100% accurate. The results were quite similar for both a cold and hot engine test:
For pistons 1 - 2- 3.
Cold engine: 105 - 110 - 100 (pretty poor IMO)
Cold engine with engine oil added to cylinders: 140 - 140 - 140.
Hot engine: 110 - 110 - 110.
Hot engine with engine oil added to cylinders: 140 - 140 - 140.
Looking at a good few videos online for Triumph engine compression tests, they are all above 150psi on a cold engine, so I guess my piston rings are worn. The increase in PSI with the addition of engine oil to the cylinders pretty much backs that up.
