1973 v7 Sport refresh
« on: January 03, 2023, 07:17:33 AM »
I pulled the v7 from storage yesterday and started a refresh. I’m going to take it down to a full crab, pull and plate the cylinders, and build it back up, hopefully without touching the original frame and tins paint. I will install new steering, u-joint, swingarm and wheel bearings, rear main and clutch seals, clutch if needed, EI and an EME charging system. It came with a full Gregory Bender wiring harness system. It came apart very easily and there is very little rust, so I’m optimistic so far.

That's going to be a looker.
How are the front shocks?  Seals OK?
I'm curious how they come apart.

I am too. I think they will be ok.  Everything so far has come apart with hand tools. I’ve ordered new springs, dampers and seals for the shocks.

How is your dad’s 650 running?

I rode it a lot this summer, thanks for asking.
The shifting has the occasional neutral between gears, which was also happening originally.
A few other things will need attention this winter.

Frame is all separated for blasting and painting.  I decided that it is scratched up enough to warrant a repaint.







The cylinders are chrome but look like new inside.  The spots in the picture are dust. I’m going to send them off for nikasil plating.







The timing chest looks great.  I forgot to drain the oil before removing the cover. Huge mess.

I'm sure this resto will be as great as your others ;)

That oil pump gear looks a lot lighter than mine did. Is it original or something a PO did?

I’m not sure Klinkhammer.  I’ll do some internet sleuthing to see what they look like. I assumed it was original, but without any basis.  The clocks are boxed and read 61k kms so someone may we’ll have been in there.

Today I got the swingarm and carrier bearings out and have the steel parts ready for media blasting.  My piston pin puller came in today, so tomorrow I can pull the pistons to send in with the cylinders to Millenium for plating.

Found some pics of my V7 Sport engine. This is what it looked like inside.

Ok now I’m wondering what the gearset in mine is.  I’ll post the question on the main board.

Steel parts are bead blasted. Off to the painter.

I dropped the frame and steel parts at my painter today.  He said he may spray them tonight. I can’t wait to start building the bike back up again.

Looks like a nice job. Do you know what paint was used? Now for the fun stuff. Slow and steady ol' boy.

I’ll go out in the garage and look today Steve. I saved a kickstand for Ken to work off of. He said that it is a satin.  It looks almost gloss.  He gave me a can of the paint and hardener for touch ups.

That will be great!
Getting the engine into the frame might be my favourite phase of a build.
Such a great feeling of accomplishment.

I agree.  It is always a fiddly job though.  Cylinders are packed off to Millenium for nickel silicone plating.  They received them and said that turnaround is about two weeks to twenty one days.  Heads are at the machinist and steering yokes and headlight ears are off for crinkle black powder coating.

I can see the writing on the wall. Once you get all the parts together (powder coat here, crinkle coat there and shiny chrome exhaust) all that nice patina just won't cut it.
Rabit hole elevator, going down. All aboard!

I’ll take that challenge Steve. The aluminum will get a scrub but no vapor honing. Paint will stay original.  God I hope you are wrong.

Nice work so far! I see that MG Cycle no longer sells the re-pop shark gill mufflers but the Competizione Lafranconis are still available. Have you decided what to do for mufflers?  :popcorn:
Also, I *highly* recommend the RAM Clutch. The pull is so light I thought I messed up the installation. Feels like an 8 spring clutch with only 2 springs in it.

I have a set of Chrome Bub mufflers from spmoto that I’ll put on until the shark gills roll back around. I’m guessing they will make a run of them at some point.  Thanks for the idea re the RAM clutch.  I’ll look into it.  I’m about to pull the clutch and see how it looks. Cylinders, heads and steering stem should be ready in a few days.
