Airhead 80-100 G/S Adventure Build

A quick question for the cognoscenti, does the HPN tank bag have a metal plate between it and the tank?

Tank bag

The base of the hpn tank bag looks like this and is secured to the tank with 4 screws. So I’m guessing no base plate required for yours.

Right, time to get this party started.

Let’s get the new kit laid out

Yep looks really nice. Good quality waterproof connectors too. Just put a light smear of di-electric grease on them - you could use ACF40 or just not bother.

First lets stick the ignition unit on.

Are you OCD like me? Check the washer:

Unit installed

Then pop the old sender unit off - though I did check it one last time just in case. No spark still.

First lets line up the camshaft and off-centre drive:

Then a light smear of assembly grease on the O ring

And on she goes

put everything back together and check, yes we have a spark!

So the moment of truth.

Fire her up and only running on one cylinder - Bollox, its the Guzzi all over again!

Whip the offending plug out and we have a spark - but the HT lead wasn’t fully pushed home so back goes the plug and a bit more oomph provided.

Here we go … (Sound on)

Great stuff, it lives …

But, rev counter not working, charge light not going out, oil pressure high.

Hey ho, these bespoke builds are never simple!
 
But some good news - a quick check with the strobe shows timing is pretty much bang on, so we’ll leave that as it is for now.
 
Nice one, was the old box of sparks an original item, or is it going back for a refund
 
Been following this build from the start and it makes so happy to hear a build being started for the first time , well done om.
things will come together really fast now that you have made it run.
once again well done .
 
Cheers Turkuss, thanks for support!

More good news - the charging issue was just a loose connection, so that’s all sorted now. It wasn’t running very nicely so I popped off float bowls.

This aperture was blocked on the LH side. A bit of carb cleaner and air did the job.

Just got to fill the test tank and I can do a rudimentary tick over and carb setup.

Engine sounds really lovely and quiet, just a gentle top end rustle and that’s it.

Exhaust however is a different matter. More vid to come.

Got the carbs sort of balanced - not bothering too much with this until I’ve retorqued heads and re-adjusted tappets.

A bit more video - the oil pressure has settled down now that its warmed up a bit. That’s as much as I’m prepared to rev it for now!

Last bits of wiring done, headlights fitted. The micro led bulbs I have are Shit so we’ll have to sort them. Tomorrow’s job is to adjust the float levels, then put fairing, tank and seat on.

Cheers!

Getting to final stages now. It’s off the ramp which is stored away for next time ….

Love how the paint ‘pops’ in the sunlight. (A detailing term apparently!)
