Cleaning

Drain the frame tube and reinstall the drain bolt. remove the radiator, send that out.
Make your mixture of ¼ bottle lime-away or whatever in a large bottle. a 2L soda bottle should be acceptable
Remove the engine block drain bolts (under the front bank. refer to your manual)
Remove the water pump drain bolt (refer to manual for location)
Once it's completely drained, send some water via garden hose through the system, let drain again, reinstall these bolts
Cap off the hose coming from the frame tube (left side)
With a funnel and your 2L bottle, fill the system with your cleaning solution through the hose leading from the thermostat housing TO the coolant pipes.
- It's important that you don't try to fill it THROUGH the thermostat housing. Why? Because the stat is closed.
Fill it to the top, then shake the bike a bit to work the air bubbles out. Fill - shake, fill - shake, until you feel confident that it's full.
Plug the hose and wait approx 24hrs
Drain everything and leave the drain bolts/plugs out. Hold a garden hose to the hose coming off the frame tube (left side).
Flush flush flush...once the water looks clear, reinstall drain bolts.
With the hose still attached, start the bike and rev it up a bit, keep the water going full blast. Do this for a minute or two and shut the bike down.
- If the water is clear, you're good to go. If it is still dirty, then keep flushing
It is important that you have the hose on the frame tube hose when you start it. Coolant flows IN that way, and OUT the thermostat hose.
