It's a strange thing but as I am approaching fitting the tank and getting close to an attempted start up I feel myself slowing down fearing unforeseen issues. I ought instead to be estatic at the prospect - is this normal !!

Oh boy, do I understand that feeling!

Thank goodness I thought I was alone with the unsaid dread!

I understand exactly where it comes from, for me.  Start with a bike I know wasn't running all that well before it sat for 3 years.  Add to that a bunch of repairs and adjustments - to a bike and to systems I'm not too familiar with, and therefore don't have a lot of confidence about.  I hope for the best, but assume things will go wrong...

Another step closer today - re-fitted old Petcock with new tank strainer used the old seal but have the two that DS supplied - petrol tank back on the bike - 4 Litres of new Super Unleaded tap into Reserve position petrol filled the little in-line filter all looked okay for a minute or so then petrol started coming out of two of the overflow pipes. Big curse to myself !

Walked away wishing I had checked the carbs with fuel before I re-fitted them to the bike had a moan with a mate who said - have you tried a gentle tap on the carbs incase the floats are just a bit stuck as they were completely dry. Did just that followed by shaking the bike from side to side - fuel back into reserve no sign of any more fuel from overflow pipes. I've given it a good 5 minutes and no more fuel out of any of the overflows. I feel happy that's good enough for a planned initial start up.

I've checked for spark - nice visible spark at the old dirty spark plugs - I am now ready to check the static timing tomorrow morning then its new plugs in place and see if she will run. The new plugs that came with the bike are NGK D8EA as are the old ones that were fitted.

Fingers crossed for tomorrows start up attempt !! :)

Set the static timing this morning took me about an hour to get it all done plus 30 mins spent making a decent loom connector & test lamp to set 1&4 then 2&3.

Cranked her over having got the oil light out first with no plugs fitted - plugs in after a fair bit of popping & banging she started to fire - more choke less throttle and away she went. Only a brief video but I am ecstatic !!

Hope the brief video works.

That's excellent!

The video works - it's sideways, but that's ok, the bike isn't moving anyway! ;D

Good news,  it's nice when you get them going.

Unfortunately for me it starts that video trail on the tube with the suggestion side bar,  and off into all sort of interesting stuff  :D
