Great news Paul! Hope that's it sorted
PS - Ref my previous suggestion - misread your post prior to my suggestion as if misfire was on 1 - 4 (hence same ignition circuit) - yet another senior moment! (becoming ever more frequent!

SUCCESS!!!!!!

New plugs fitted today, synced carbs, sorted malfitting plug caps

PURRING LIKE A KITTEN NOW

This has been a frustrating but valuable learning curve but with fully reconditioned head, new plugs, new inlet rubbers with decent clips and nicely balanced carbs this bike is running smoother than it ever has. Ticks over lovely at 1k

Yet to get out on the road but all now looking really good

Many thanks to all who have added advice and wisdom over the last few weeks, that’s why this forum is so great and the advice and ideas have been so much more useful than the so called pro mechanic I used. I am not dishing him just that intimate knowledge of these bikes is so valuable which he did not have.

Some times it is obvious that it is unbelievable  :o

Had a twin in last year for a new cam chain, easier to drop the engine to do this job. New chain fitted, engine back in but, no spark. Instead of the mind thinking, no electrics have been disconnected apart from the alternator, i started by changing the plugs, then the coils and caps, then the CDI unit, then the pick up. Lucky i had the same bike sitting in the workshop so just swapping parts and scratching my head. Right i thought, it must be the ignition switch and as i lowered the ramp, i noticed the kill switch was off  ::)

I think that most of us have been caught out by that kill switch Graham

Kill switch! It happen to me too! I can imagine that... I never use it, so if by whatever chance it becomes off, I have problem ;)

Pleased to hear it’s just not me that misses the obvious sometimes. Spent 5 minutes in Ireland this summer pressing the starter on my Yam Tracer and engine not turning over, eventually realising it was in gear and there is an inhibitor switch that stops you starting it in gear!!!

Well finally got out on the road today and pleased to report that after all the work my bike is running better than it ever has👍👍👍👍 just a small panic caused by a kinked fuel feed hose after 2 miles (easy fix!!)

The new rubbers and decent clips have resulted in a smoother tick over than it has ever had and the head skim has finally resolved the oil leak where this tale began ( oil was seeping out around the timing chain area of the head)

Many thanks to all who have helped with advice and put up with my frustration over the last weeks, this forum is just a great resource
