ok so i just got back from riding glamis on my 450 and noticed a clunking sound in the bike. i tore it down to find it was full of sand. i believe everything is still ok i just need to flush all the sand out, what do i use?
If your engine is in fact contaminated with sand, the only way to really deal with it effectively is to pull it out, tear it down, and clean it out thoroughly. Amy half way measures are an invitation for trouble. If it's a steel bike, be sure to get the tank clean.
Does Yamaha really put the breather down on the frame. I like Yamaha but that has got to be the most bone headed move ever.
I ride the deserts and dunes a lot, and have repeatedly checked the top of the breather tubes of the 4 YZF's I've ridden there. I have never found a trace of grit in it.
