750 K1 project
Nurse Julie:
They have come up fantastic Mick, great job 👍👍👍
Andrew-S:
Carbs look great, it may be one of the jobs I'll have to tackle on my K1.
Crispy:
Pleased to report that I've had the oil tank repaired, I've painted it and it's now fitted to the bike along with whatever else I have that is ready to bolt on. I need to sort a brake out next as the bike is getting difficult to stop when I roll it back into the garage from my hill of a drive! :o Can anyone enlighten me as to how the oil tank works? In particular what does the pipe connected to the crank case do? Is it just a breather? Thanks! :)
SumpMagnet:
Looking much shinier than my efforts :)
Not sure about the K1...but my F2 had a complex arrangement of pipes coming off the crankcase, through a catch tank bolted to the bottom of the battery box.
It wasn't connected to teh oil tank...the oil tank had a breather/overflow pipe running from the top back side of teh filler cap...straight down to the deck.
Now....that may not be correct...but it's how mine was when I got it
K2-K6:
The F2 came in the era of emmisions and trying to avoid output to atmosphere. They effectively collect any oil suspended in air (smoke to most of us) and seperate it at the air filter contraption to burn any contaminant by drawing in through intakes.
The early tanks vent to air from the top generally, they have a built in air oil separator inside the tank that splits oil vapour to drip back into oil supply, with air going out to ground. This is from description in KO manual, you'd have to look at later manuals to see your K model.
They have to vent both tank and crankcase, ultimately to atmosphere, to prevent overpressure in engine.
Sealed completely, it'll try to push oil out of oil seals etc. Also interferes with dry sump system on 750 as you don't need either vacuum or pressure exerting against oil pump operation.
