I would use something light, like kerosene, to cut the oil and give the sand nothing to stick to. Then stick the nozzle of the garden hose in there and flush it as best you can. Then another round or two of kero to displace the water, and some 2 stroke oil on each bearing before assembly.
I don't think a brief water bath will hurt a thing, and you're gonna need something under pressure to get any debris out of the case. Kero by itself isn't gonna float sand out.

how would you do this with the motor still in the bike?

Take it out. It's a quick, easy job and it makes it so much easier to work on. Plus, less chance of crud getting knocked off the frame and ending up in the case.

I would venture to say if you look at seafoam...it might do what you are asking. To do a flush it has detergents in it that will help in eliminating garbage...but to remove sand...hmmm without a hard flush...like with a water hose....it is a hard one to say. I have in the past run seafoam in mine...started it for a few moments....drained...then flushed with water....then rand about 2 quarts of oil THROUGH it...then filled it...ran it for about 5 minutes...then drained and filled again. The reason for the excesssive oil use it to eliminate the water. I never had problems...but that is just my $.02

Also...if you do not like that idea..then pull the motor and split...but the only issue with that is if you pull it might as well go through it too...and that to me is alot of jing that i dont have....

thanks airborn. IS there a drain plug? i looked but didnt really see one.
i dont think much sand made it past the carbs and into the cylinders. ide really hate to pull the whole motor out but im not one to do things half
assed. thanks for the info!!

The drain plug is at the bottom almost in the center...becareful not to remove the bolt for the support in place of the actual drain plug... but good luck my friend....and I hope all is well....let me know how it goes!!

oh cool, there is a drain bolt!! i didnt see one but i will look again.
I will keep you posted, just waiting for the machine shop to finish boring
and porting.

I believe the drain plug you refer to is actually the gear oil drain. If there IS a way to drain the crankcase, there would have to be two plugs, one for each side. In my experience, very few engines have drains for the crankcase. Polaris snowmobile engines (Fuji) have drains, but my 91 Banshee does not.
