What's the best thing to flush my engine

I hope your frame wasnt blasted with steel grit,a couple of particles of steel grit will destroy an entire engine.Nobody uses sand any more,its banned for health reasons. Regards John.

Hello the only way to get the engine clean is too strip the engine down and clean with a paraffin blow gun ,so you will need a compressor a 2hp one 50 liter tank ,ever part inside you engine needs to be cleaned well so to make sure that it is you need to stip the engine down as it will been in the oilways and the pump and inside the crankshaft as well ,I had too do the same thing with my 650 as I have bits of alloy in the oil from one of the push rods had come out of its ball socket and the other one was knocking bits of it , is taken me a month to sort out now my engine is back in one peace and in the frame ,yes we know its hard work but its the only way you know for sure ! your anna j
