Hi
I bought a motorbike brand new. It has a 4 stroke engine with nikasil lining. The first ride out of 220miles it used almost half a litre of oil, second ride was the similar. Oil consumption dropped to a rate between 500ml per 1000miles and 900ml per thousand miles, till about 1500miles. Up t this time I was running iin by the book, keeping rpm less than 7000rpm.
Once "run in" the bike went back to almost 2litres per 1000miles.
From the first time out I continually complained to the manufacturer, and at 1932miles they agree to inpsect it.
They found, carbonised pistons and damage to the crank.
These parts were replaced along with new piston rings.
My questions are,
1) how likely is it that the new rings will seal with Nikasil bores which have covered 2000miles?
2) Will it be as good as new?
3) Is there much chance engine power or longevity being compromised?
thanks in advance
