Post subject:  Water pump qu.

Hi all, I'm new to this forum. I'm 47 and race Pre-85 class at my local motocross club (in Australia) plus other events like grasstrack and vintage mx, all on my restored CR250RD.

I'm emailing to see if anyone has any clues: when I last changed gearbox oil, its was milky, and I'm worried that's due to water leakage. The water pump was fully rebuilt a couple of years ago and all seems well with it. But maybe its a leaking oil seal in the pump? Any trick to replacing the clutch cover/water pump back on to cases (maybe I didn't put the cover back on correctly when had to replace third gears a couple of months ago?).

Thanks for any tips. Its a great bike otherwise, and can't wait for my DG pipe to arrive (any tips on rejetting for these?).
