I didn’t even know that was a thing. The bleeder kits seem pretty cheap, I’ll have to give it a try. I run engine ice and change coolant every spring. I always end up having to do a few heat cycles to get the coolant level right, it would be nice to get it on the first try.
I love them. Helped a few mates out with cooling system issues. Just need to make sure your compressor has the herbs to create enough vacuum in the system. Anything bigger than the cheap / really small ones will be fine. Make sure the kit has the right size rad cap adapter fitting. Went to do an RSV4 the other week and my kit didn't have the right fitting.
Like the ones in the bottom left corner
Of course, but you can’t beat these things for a 100% perfect fill. Some systems harder to bleed air out than others.
The interesting thing about this is you said it only leaked after having it constantly spooled up in low gear. Go do it again and see if it does it again. I'd like to see what the newer pumps changes are.
Ok. If it does it again, try changing to a lower pressure cap, doing it again see it stops it. It wasn't really that hot though, was it? Seals will sometimes get the minutest piece of crude on them and leak and then recover (sorta like bug guts causing Ohlins to leak). Weird. I just had a thot. The pump runs off a gear that's integral to the idler that reverses the primary rotation. This gear is floated on an eccentric that when you assemble the motor the backlash between the three gears (crank, idler, clutch) is to be set with no bias. If that were off a bit would it put a pulsing load into the pump mainshaft that showed up as a leak at high RPM?
That exists, but it's about $1K.
