Is it a difficult job to change the coolant in the 650 does anyboby know whats invoved or any tips? thanks
Any tips? Yeah, get hold of a Haynes manual or the Honda workshop manual (but that's harder to find).
As for the job itself - not that difficult but a bit long and tedious as the fairing has to come off - just so's you can get to the radiator cap. Seriously! Actually you might be able to get to the radiator cap if you remove the Right Hand fairing inner panel and then remove the plastic radiator guard.
There's a small drain plug on the bottom of the water pump - you could get away with not removing the belly pan, but it might make collecting the old coolant a bit messy.
Other than that, there's not much to it. Refilling is done via the radiator and after running the bike for a few minutes, topping up the radiator and reservoir.
