I`ve got a strange problem. I rebuilt the bottom end of the engine - new crank, bearings, clutch plates and springs, of course new oil filter. I also checked the oil pump and it is in v.good condition.
I filled the engine with +- 1L of oil and when I checked the oil dipstick it was dry.... I`ve checked the engine oil level a milion of times and never had such an issue. I filled the engine with more and more oil and there was still no oil on the dipstick.....
What could be wrong?
I must admit that I didn`t check the piston rings... my fault, I know... The piston and rings have 30 hours already, but it could be worn... I burnded the clutch and all the crap from the friction plates were in my engine...
Afther the rebuilt the engine was washed throughly with brake cleaner and all the dirt removed. Next I filled the engine with oil, ran it for a couple of minutes and flushed the oil. Nextly new oil was poured in
I followed every step mentioned here http://www.thumperta...9-model-yz450s/
