Valve stem seals

check with Nurse Julie for the pucks and other o rings

All sorted thanks, genuine Honda on the way to me, going to take the head apart today and probably grind the seats and clean up the head, tempted to have a look at cleaning up the ports but knowing that it's easier to make things worse rather than better I'll leave it alone, not trying to make the bike much more powerful,  just a little more comfortable at motorway cruising speeds

OZZYSBIKES:
Well, you live and learn or more correctly you live, learn, forget and learn again !

Got the head stripped and all is well, valve guides are good, camshaft bearing surfaces very good, the bit that I have relearned is not to order the parts until it is fully stripped down as you never know what unexpected things might be needed, in this case three of the inner valve spring seats (shim washers) are missing, I could understand if all eight were missing, the builder might not know they are needed but to fit five and leave three out ? Or perhaps just remove and refit some valves but not check them all ? Well it goes against my thinking,

Well hopefully that's the last obstacle to the rebuild

Trigger:
You could find them stuck to the bottom of the inner spring or on the floor by now  ;)

I checked all of the above and below (on the floor) they were missing,  now ordered so should be able to have it back running on Wednesday,

It doesn't surprise me with some of the work on this bike, it has a spurious exhaust system on it and the back brake lever hit the exhaust and the side stand wouldn't fit, I removed it completely, refitted it correctly and now the side stand is fitted and the rear brake lever doesn't touch the exhaust, hopefully nothing much left on this bike to surprise me !
