Coolant Flush

1.  Place a bucket underneath and unscrew the first coolant drain bolt(10mm).

2.  Place a bucket underneath and unscrew the second drain bolt(8mm). If you take it out slowly you can get most, if not all, of the coolant to come out the other drain, thus saving you from having to clean too much off of your engine.

 3.  Now unscrew the radiator cap (not pictured).  Then pour distilled water into the radiator until the water coming out isn't green anymore.  It should take almost one gallon.

4.  Place one of the buckets underneath the reservoir tank and remove the top hose.

 5.  Remove the bottom hose while holding a funnel underneath to direct the coolant away from the engine.

6.  Unscrew the reservoir filler cap leaving the hoses disconnected.  Then pour distilled water into the reservoir until the liquid coming out isn't green anymore.

That's where I stopped because I'm waiting to fill it back up until I'm done checking/adjusting the valve clearances.  Here are the steps to refill the coolant though for future reference.

1. Screw both drain bolts back in and torque to 87 inch-pounds (7.25 foot-pounds).
2. Connect both of the hoses back onto the reservoir.
3. Slowly fill the radiator with coolant up to the filler neck. The slower the better as to avoid creating air bubbles. Leave the cap off.
4. Fill the reservoir tank to the max line with coolant. Leave the cap off.
5. Start the engine and continuously tap on the hoses on both sides of the radiator to get rid of air bubbles. Do this for roughly 30 seconds.
6. Stop the bike.
7. Fill the radiator up to the filler neck with coolant. Install the radiator cap.
8. Check the reservoir tank level and fill back to the max line if needed. Install the reservoir tank cap.
9. Start the bike and keep it running until the radiator fan comes on then turn it off and refill the reservoir to the max line.
10. Clean any spilled coolant and you're done.
