hello all am thinking off changing my coolant on my 210 gas gas pro 250 how do i drain the coolant? also on refilling do i just fill the rad up to the top? and do i put it in slowely like you do with a car? am new to these gas gas bikes. am used to bultacos

I did mine the other day, 2010 300.

Just topped it up with 50/50 water/ antifreeze.

The rad cap is under the tank.

To drain first just find the lowest hose connection or a water drain. (must have a look for it on mine now I've said it, haha. )

Undo the clip on the lowest hose and drain. It's tempting to take out the brass Torx bushing to drain the system

but I would avoid that as there is a very thin thrust washer you will probably lose down into the impellor. Fill to the bottom

of the radiator filler neck and if you overfill, don't worry, the system will dribble out some coolant from the overflow hose

for a bit, just expect it. Use 50/50 mix of distilled water and "regular" auto anti-freeze (green, not the orange long-life newer type).
