Paul I have the genuine Honda spring compressor for getting the valve springs out. I can pop round after work one night and we can get them removed within around 10 mins if you'd like. It would be around 8.45pm though.
Hi Ken
Thats a very kind offer but I am going to drop head off at my local machine shop for them to do the work as am going to use the opportunity to have all checked, valves reground in etc whilst head is off
I think better to get valves professionally checked rather that rolling them around on glass as I suspect the bend if there is may be only slight but enough to cause them to stick when warm.
Welll just my luck!!!!!!
machine shop called me yesterday all the valves are good and no bends anywhere in sight
Having head skimmed and valves lapped in anyway whilst it’s there but......
That means still no nearer finding the cause of my running problems and think I have exhausted all things to check
This is soooooooooooooo frustrating!!!!!!!
I have now checked and tested the following.....
Carbs stripped and idle circuits checked, no pilots blocked
Good even compression on all 4 cylinders
Complete ignition system back to Boyer for testing and no issues
Leads and plug caps tested and all ok
Valves checked for any bends, leaks etc -all good
Am really now clutching at straws but have one final theory
I put 2 small lengths of nitrile fuel tubing on the tank petcock and connected these using 2 right angle elbows to the carb hoses. I cannot see any kinks in the tubes when installed that would cause a fuel cut off to carbs 1 and 2 but is it possible that by using these right angle connectors that I am somehow upsetting the fuel flow as they have a smaller bore than the hose of course

See my other post today about petcock behaviour
This may sound crazy but I am now really clutching at straws. I seem to remember a post from another member about these bikes being very fussy about hose routing and dimensions
Whilst all is apart am going to get rid of these connectors and put some new hose direct from carbs to petcock to eliminate this as a possible cause
