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.
Thanks Triumph for your crap piston ring design
