Hey Everyone Hope everyone is safe and well, and having a great day. Just wanted to get your thoughts on whether I should do some kind of flush of the engine before changing the oil and filter? I've just ordered the following: 4L Castrol Power 1 Racing 4T 10w-40 K&N Powersports Filter K&N Air Filter Working from home at the moment means I can find time to tinker! It's not due for a service for a little while yet, but wanted to give her a breath of freshness. Can't do any harm giving a little extra TLC can it!? So a few pointers would be great: - Should I do anything special to drain out the oil and any particles? - Oil is the correct one isn't it!!! Anything else that you might recommend? Spark plugs? Sorry for it being a little open-ended, but I don't mind spending a bit of time and energy in making sure it's running as efficiently and smoothly as possible. Ah (in Colombo style) one last thing! She runs very hot, 1 indicator less than maximum when she's stood still for any time. Once running and the air is flowing then I can get down to 2, sometime 3 bars under maximum. Should I drain and replace the coolant with anything super-special? The bike is not tracked, just ridden round North Yorkshire and for as much pleasure as possible. Thank you for any and all guidance; much appreciated.
