MZ250 ETZ Oil capacity

[mzgaffer]

Hi ,,Just bought my bike yesterday
wondering if there is a sevice schedule i can look at on this forum ??

Right now would like to know oil capacity and type for the engine/transmission

I tried to top it up earlier (undid screw by gear lever,,topped up till it ran out ,,is this correct ??)

The oil came out like a milky grey / white substance ,,

Would this mean water has contaminated it ?? how would that happen ??

Anyway ,,Thanks in advance for any answers

The oil came out like a milky grey / white substance ,,

time to find the drain plug and flush it out you have water .....
just setting around for years will do this in a humid area
most German bikes the practice is bike level .... oil to bottom of plug threads its full
if its a 2 smoker no oil in engine its added to gas as a mix or placed in a auto lube system tank
dave

exception is 5speed in 1974 r90s bmw lay on side and do 1 full usa quart
they did the fill hole too low on the side of the trans on the one i had
but i found a bunch of funny stuff on mine over the years
like the seal on the shifter shaft was for a 4 speed box if you ordered one for a 5 speed it did not fit
but there were 5 speeds inside ....i think i had been sold one that was supposed to stay at the factory
took it apart to do the points and it had a boyer pointless system in it
very strange bike as i took it out of the crate at the dealers myself
the timing chain had a master link ????
like i said very strange bike

Hi mzgaffer,

I see I've arrived too late to be much help here, as there's already a link to the manual above and you seem to have done all the work anyway. But for what it's worth - yes, the correct amount of oil is "enough that it runs out the little hole by the gear lever"

And yes, the whitish grey gunge indicates oil that's probably been in there for quite a while and has water "issues", get it changed ASAP!

That's a proper Z-cred repair to the crank-case there! Nice work! I have to admit that on one of my 2-smokes I eventually gave up on the oil pump as I couldn't get it to bleed through one time, and ended up pre-mixing in the old-fashioned way for years. Didn't seem to do the bike any harm. But for convenience I think I prefer the pump if it's available.

Enjoy the smoker though, may you have miles of smiles!

Hi Anna

Thankyou for reply ,,,,,

I think my problems came because the guy i bought my bike off (he has only one hand)
didn't adjust the clutch properly and the tube that goes in crankcase to hold the clutch cable ,,was flailing and flapping about ,,so water would have got in there !!

(I turned the plate/washer around under the cover and it sorted the adjustment out )

Oil changed but my repair is leaking still ,,guess i will have to jb weld or alumiweld it or something

My bike when i got it did an easy 80 mph ,,now it does 70 mph and if held for too long at that speed it fades and stops ,,, seems to like it at 55mph and will run ok at that ??

I have a B6HS spark plug at mo ,,colour is light brown when i take it out

Exhaust is peppered with tiny holes ,,have a split air box rubber ,,, any help in getting the power back i would be very gratefull of

Hi anyway ,,,,,,,

Hello MZgaffer!

I suppose must be manual like this in Spanish and English... I don,t founded.

Owners Workshop Manual Haynes MZ ETZ models 1680 is other opcion (not so good).

I don,t speak French, German only a bad Spanish and a very bad English but with love for this machines, a pencil, a traslator, common sense and patience no idiomatic barriers ...we can.

Regard, Manuel.
