[quote="pomartin"]update
i got crankshafts, some stickers and outside part of engine is half way pollished.
at the moment i do not have time for this... we got final exams in school and it ends 6.9.... so till then, this would be it
Is this crankshaft really black ?
If so , can you tell us more about it ?
Is it a special brand , it looks like a hardend type of crankshaft.

it is not black.. it joust seems on picture.
this is copy of CTX crankshaft, made in serbia, the other ones are original CTX. Originals are a bit better than copies, but the problem is that there is almost no good CTX original ctankshaft.
all of them have racing bearings

ctx is 80
e90 is 90
well, there is no such a problem finding an engine... but they are a bit expensive.. around 250 and 300€.. it depends on its condition

3% of oil is usual ok.
If you use some cheap mark or non-syntetic oil i would reccomend 4%
with motul 710 (or better) is 2,5% enough.
And main rule: better too much than too few
hehe i would like to see it finished too... its about time.. 26.6. will be exactly 8 months from when i started

4% is indeed 1:25
With good oil 2,5% - 3% (1:40- 1:35) is enough.
By the way, looks very nice.
