Found this old skool carb shop on my travels.  Had boxes and boxes of carbs and bits all over the place, but they guy new exactly where everything was when asked.  Manged to get some replacement vacuum port screws for my carbs as the old ones were all chewed up.

Delkevic exhaust arrived and put on.  A little bit fiddly getting it all lined up but nothing too difficult.  Would have preferred to use the original fancy end flanges with the fins on but they aren't used with this system.

Coils and HT leads cut to length and attached.  Heres the current state of play.

Not too much to do at the moment - im waiting for my battery/electrics box to be 3D printed and also waiting for a load of stuff to come back from the being chrome and yellow zinc plated, so been messing around with a few paint schemes.  Here's what im thinking, charcoal grey and silver, with an orange pin stripe!

Colors look good together.

I think you'll find it far ore comfortable to ride your bike with clip-ons if you install some rear sets.  ;) Reaching so far forward then having your shin hang straight down is not a natural position.

Yeah I wasn't originally planing to use clip-ons but they just make the bike look so much better than normal handlebars.  I have long arms so will see how it goes, but yeah might have to look at getting some rearsets.  Ive just sent my old rear brake arm to be chromed too  :-X

Speaking of clip-ons, the only way I could get them to fit without hitting the tank was upside down!

With long arms and/or torso, clipons are less of an issue, but you should swap from the stock pegs to rearsets.  Otherwise you lower half is aligned for more upright riding and you will be bending your back more to reach the clipons.   Rearsets will position your body in a forward lean so that it is more natural to just reach for the bars and not be bending your back more. It also allows you core to support your body better.

Lots of shiny things back from the platers!  Im really happy with how well they came out, especially the yellow zinc on the carb bits.  Before and after below.

Finally got my electrical box 3D printed...  Took a total of 55 hours of printing to get through it.

She's alive!  After a year of blood, sweat and tears I started the old girl up today!  Couldn't get anything out of her at all for the first few minutes, but then noticed that the kill switch was off!  After correcting that she fired straight up.  Here's the second start below.  I never heard it run before but to my novice ears it sounds like its running pretty well.

Carbs were bench sync'd using ball bearings and the current settings are 105 mains jets, 42 idle jets, needles one clip up (however the needles are the E2350F ones from the 500 as opposed to the 550), pilot screws 1.5 turns out, and float heights of 14.5mm.

Nice job.  I like that printed electrical box.  Can you post a shot of it installed with your electrical components installed and wired up?
