[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

Oke

I wanna buy a ctx 90 or 80 engine but i cant find it so are they so special in your country?

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

little update
There is a change in styling.
CTX rear forks with mono-amortizer .. and all what needs to be modificated

as always looking nice

id really like to see it finished

ps: do you know which gasoline/oil ratio you need for BT-Cyl, some say 1:20/1:25 and other just 1:40 , 1:45

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

Okay 50x1,04 =52 that is 2 liter oil in 50 liter is" 1:25 "

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

tnx
I will start working on it again on friday, couse in thurstday we have last final exam

Good luck with the exam!

yes good luck

i hope you finnish it
Than you can make alot of money for more intresting projects
