One step forwards...

It's been the never ending story trying to get the fuel pump to work normally.
If I wire up the pump directly to the battery, it worked. If I connected into the harness and turned key, the pump never worked..
So tonight , for the first time, I swapped around some of the relays and tried again.
I swapped the 25G-01 for 3GM relay and this time on turn key, the pump worked...and kept working without switching off...
Looking around the forums is also a real head scratcher...there is a lot written about the 25G on the Virago forums...half state it's the relay for the side stand and the other half for the fuel pump....

So, common sense here: the racing sprint harness that came with the bike only had a 3GM blue relay in the harness and no white based 25G. So I'm presuming I've wired it up wrong and I've fitted them into the wrong places in the harness. The positives are of course, that I can finally get the behemoth outside and start her up!

expensive sounds...

After the initial start-up of the OW01,
I haven't had time to get back down and see if I could get the bike running longer.
Tonight I went down to the bike and had another go.
This time, she started up and I managed to keep the bike running for a few minutes.
Everything seemed to be going well, but suddenly a really nasty sound was heard. A really high pitched screech, but it wasn't a constant.
I took the cam cover off and couldn't see any issues. But there is an issue for sure.

By all accounts I'm guessing it's going to be a proper issue....no idea what as head, but I reckon step one will be to whip the head off.

As I've never heard that sound previously, I'm clueless as to what the damage could be.
Facts are:
a) the sound wasn't there until after I kept her running for a few minutes.
b) the sound wasn't there any other time when turning over the engine- until she started and ran for a while.

it's only happening at a certain degree of when the engine is turning over...

Valve? Piston ring? spring? seized something?
