Still waiting on pullers which i ordered last Sunday night :ranto that's temporarly put the kabosh on getting the flywheel off till next week, so took the engwin out now.

I noticed i had'nt removed the water pump when i pulled the oil pumps so set to it, wot a booger, Haynes mentions it could well be vacoomed in on the 2 impeller seals but blimey, dont see how i could pull the shaft out without damaging it ! Or is the back part of the pump housing meant to be prised away from the crankcase !! Haynes mention's prying but it's a little confuzziling, anyone.

So a bit stumped with the water pump went on to removing me 2 stuck shim buckets, so Proxxon in hand with a grinding stone (Pink stone borrowed from a 9r chap) started a grinding with success (good man Studs) but still needed pulling with some molies, was a bit afraid off grinding to much and buckets is cheaper than cylinder head. Looks like the aluminium has been peened over in parts !! In fact it's right where the oil hole is peened over either side.

Here's the worse bucket, if'n you can see it

One of those valves was a bit stuck and you can see some pitting on the top of the stem, may have to replace that one

So wot to do about the cam bearing now where i have had to grind, one bucket is still a bit tight and cant pull out with a magnet,only molies, some wet/dry maybe and smooth it off perhaps.

 

Also had a quick gander at the frame around the inside of the swing arm bolt and a cursory glance is not highlighting any cracks, need to wash all the crud off and may shift some paint for a better look but here's hoping i'm all good.

Now those last 2 shims are out i have all the measurements for me valve's, all bar 1 in spec but a good few are somewhat tight,   clearances then shim size in red in case it's not obvious to somebody.

That's all for now folk's.
