Re: Changing oil with an anti-draindown valve fitted
It looks like a Bri Tie valve, same as I have fitted on my KH. I would not bother draining the oil pipes or a major priming exercise is needed as Paul describes, Check the unions for tightness regularly and they work perfectly. I had the return side union fail on mine due to a cracking pipe, fortuna...

Re: Mystery cause of sticking inlet valves on Mk II engine.
Paul It might be an oil carburisation / burning problem if you are not using the oil cooler. Experience with racing Honda Cb77's in the IOM, notoriously hot running engines, was that even R40 castor oil was turned to lacquer and vinegar in 6 laps with high consumption without an oil cooler. Another ...

Re: KH Crankcases

Very sorry to hear this, the whole area is a disaster as far as access is concerned, Hopefully the job will be stronger than original when welded up and at least the engine should go back together with no problem

Re: Oil weep from feed pipe nut
On my KH 500 it did that for a while and then became dramatically worse, the pipe was cracked around the soldered on olive

Re: Oil carry over- SQ4
Is it rebored? You may need to use running in oil if it is

Re: Another prat pulled out of the side road without looking
Paul Very sorry to hear this and hope your wrist is not too painful, and the sq four is not too badly damaged. The standard of driving by many is truly abysmal these days. I am just getting the KH back together after my recent front wheel puncture and unexpected arrival on my friends driveway! Best ...

How hot is hot enough to straighten a footrest
Repairing the accident damage to the footrest on my KH. I have sourced another one, but that's a two piece affair with the peg bolted on. My attempts with a map gas torch were completely ineffectual, and I suspect the material is malleable cast iron or SG Iron as they say now. Does anyone know what ...

Re: Mystery cause of sticking inlet valves on Mk II engine.
Paul Do you run an oil cooler? Experience running Honda cb72 engines( notoriously hot running in race condition) in the classic Manx GP on Catrol R30 Castor oil broke the oil down to something resembling vinegar with brown lacquering all over including the bores. The following year bored out to a fu...
