well

i made that same newbie mistake 2 years ago with my 91 rm250. I also just turned over my bike to get rid of the water, and threw some 2stroke oil in the crank before mounting my piston and cilinder.

It smoked alot when i started it :smirk:, but that's because of the oil.

For the rest, it has been 2 years now, and still same crank, bearings, rod. Everything is still perfect, and i ride almost every week, and mostly very heavy sand.

So i wouldnt be worried!

thank you so mutch i love my bike and didnt want to get rid of it
