My 2000 ZR-7 had 26.500km (16.000 miles) when I bought it. The sale included a small service check up, with new oil and oil filter. The oil used was Motul half-synthetic 10w40.
At 28.000km (17.000, miles) I noticed I needed to add a bit oil becouse the level was at Low. So I bought a liter of Motul half-synthetic 10w40 and filled till Full.
But after this..the oil consumption went totally out of line!
Now at 29.000km (18.000 miles) the one liter can Motul oil is empty.
Yesterday I filled the oil level to Full..and after one louzy ride (50km/ 30miles) it was at Low again.
*How do I check my oil? Allways on center stand with cold engine.
*How do I drive: sporty but allways warming up the first few miles.
*Any leaking: no, no leaks nor 'sweating' oil.
*Any other changes? Yes, I changed the stock exhaust by a Bos can (with db-killer). I didn't change the manifold, air filter, mappings etc.
Another small issue: everytime I rev up to 6.000 rpm or more and suddenly release the throttle, the exhaust sounds a 'booooom'. No flames, but I do get blue-grey fumes at that very moment. Only the Bos exhaust does this, didn't have this with the stock exhaust.
Any idea what could be wrong?
