Before I go to Majestic Trails,I want to service the bike.Should I just drain and fill or flush the radiator?
What's the procedure to properly do either one?

On my quad,I drained the old coolant,used a mix of vinegar and distilled water,filled the rad and ran the engine a few minutes,drained and filled with coolant.

I thought there was a bolt to remove for "burping"

The bikes are a little different than quads. When I did the same on my two E440's I used to have I did similar to above but just used water. However both bikes would not circulate coolant when first running. They'd build up tons of pressure in the house coming from the head but wouldn't flow it through the engine.

Both times I had to loosen the upper hose and let the pressure out. Then it seems to flow fine without issue. Not sure if I just had some fluke incidents or not, but that was my experiences.
