Thanks to all for your replies.
I tryed going through a few easy tests today before taking her to a mechanic. It was raining very heavy here today (more so than usual for rainy season) and the bike is outside so i didnt get much done.
What i did do is do a compression check. The first reading was 50 PSI (344kPa). Then i put a couple of ml of engine oil down the spark plug hole and re-measured, this time the reading was 55 PSI (379 kPa).
Now my manual doesnt say what the compression readings should be so i cant read much into these numbers. Does anyone have a idea what they should be?
Bear in mind that its a 400cc LC4 not a 640. The 400 manual says the ratio is 10.3:1, the 640 manual says 11.5:1
I also drained the oil and looked at the sump magnetics. There was a lot of metal on them. Normally i might see a speck but there was a lot and some of them appeared biggish to me. I´ll try and post a pic later.
So tomorrow i´m going to track down a good mechanic. Anyone know one in cusco?
Thanks,
Eamon
