nsr 125 milk in the crankshaft

[robbie21mcn]

hi peeps need a hand i got this bike finally up and running but i seem to have baileys in the crank shaft as indicated in the photo's anyone any ideas as to where the water is most likely getting in? it was not there before about a day ago but once running i had problems with the water impellor pump leaking water outside the bike and got it torqued on and assumed thats where its leaking inside but i took it out again and it seal seems water tight. is there any other places on this bike the water could get in?

looks like your water pump seal has gone it happened on my dt the seal is just behind the water pump propellar i think and the seal for mine was £13

the seal looked ok on mine aswel but once i replaced it the oil didnt turn milky anymore but before you fit it wash all your clutch and everything in petrol just to get it all the contaminated oil out

I think that's the gearbox oil, not the crank.

Don't know how to solve it though

[robbie21mcn]

is it possible that the water can be leaking in through the head?

can anyone tell me if its possible to leak water from the head to the gearbox on these bikes? or is the only entry point at the impellor?

I can't see water getting from the head to the gearbox on a two stroke. I assume the bike works OK otherwise

[lee125]

i dont think the water can get to your gearbox from the head.if the head gasket has gone you can check by taking the spark plug out turn the engine over with the kill switch off and see if water splashes out but really i think the only way water can get into your gearbox oil is by the woater pump seal behind the propellar
