Hello. I'm after reassurance, or otherwise.
I removed the standard MC28 overflow bottle and replaced it with the smaller HRC style one. Now the tubing from rad filler to bottle is transparent I see coolant overflowing into the bottle, well before the temp is very high.
With the radiator cap off I can clearly see the level drops with a rev of the motor, I cant see any bubbles possibly indicating a gasket problem, but sure enough the level rises a fair bit.
I'm hoping to hear 'air lock', I recently changed the coolant and leant the bike at all angles etc to bleed it.
There's a track day at Brands Hatch Wednesday, I was hoping to ride this thing at last!
Thanks for any help.
