Sunl SL250-22 Cooling Issue

[bnc]

That's a shame. On my bike the coolant goes all over the place even the carburetor. I dread to think how I would get sludge out of all those places. It would not be just the engine but every rubber hose attached to it that contains coolant. Beware using any cleaner with silicates. My bike has a water pump with a mechanical seal that is damaged by silicates.
