Need Help Flushing 250r!

[Holes]

Quad over heated and took chunks from my piston.. Anyone know how to flush the bottom end?

By splitting it anything less and your just asking for it to come back and bite you in the ass.

I got real lucky when mine did that. I used carb cleaner and sprayed it down good and then used a shop vac to suck it out a couple times. Then I put the bike up on its grab bar and sprayed more carb cleaner in it and it flushed the rest out. I have ridden probably 10 hours since then with no problems at all. I know that wasn't smart but I was feeling lazy and I got lucky.

lay the motor on it side and take engine cleaner and spray in the botom end real well, take a water hose and flush the piss out of it.
Then immediately dry with with a air hose then oil everything with fogging oil while rotating the crank.

Or take the motor apart if it makes you feel better but I have done this more times than I care to remember with no issues.

When I am away from home I have used brake, carb cleaners and straight alcohol to do the same but I feel they are a little harsher on the seals so I prefer the engine cleaner and water method. You just have to get things dry as fast as possiable and oiled back up.
