750 S3 - the recommisioning

[canuck750]

A box of parts arrived from HMB in Germany today, misc rubber bits, brake switches, the long steel brake hose that links front to back and a clutch cable with the lock out switch.

Repro hand grips



Shift and brake pedal rubbers



The brake switch and steel line at the rear splitter



HMB even sells the little rubber sleeve (just a piece of split hose but its as per stock)



The front end of the steel hose to rubber hose



Repro fenders do not come drilled for the brake line brackets. punched and drilled







And I got the original coil wire cap as a gift from 'Guzzista' - Thanks for that!



Not much left to do; fit the distributor, the clutch cable, some wire connections and then it will be time to fire it up,

[canuck750]

The post office returned my long lost flywheel, it never made it to Ed Milch's shop and it took over 4 months to find its way back.
Now I can transfer the timing marks to the RAN clutch.

Guzziology says to install the distributor at the static timing mark, second mark above D.

My V7 Sports had a static timing mark very close to the D.

Here are pictures of the flywheel, the red line is the D. IS the 2nd yellow line the correct static mark?



I just want to be sure

The red line is the first line or TDC, the first yellow line is static and the second yellow line is full advance.

Thanks Joe!

Its finally done, I rolled the S3 off the lift this morning and put it on the trailer, its in storage in another garage waiting to show it next weekend in the International Motorcycle show in town.

I filled the tank with Evaporust for a week and got the inside spotless. No gas yet, I will fire it up after the show.









I brought this out of storage to keep me busy for a while

As usual, great job.

Beautiful!

What are your plans for this one? Have you decided how much of the bike is S?
I really enjoy your posts and appreciate all of the excellent work you do. It is so easy to sometimes say "good enough" when knee deep in a project.

Thanks for the kind words fellas,

For the 750S I plan on restoring it to full original spec. I have found all of the parts I need to make it correct. I have rebuilt a pair of the correct Borrani wheels, sourced a rebuilt final drive from an Eldorado, found a correct pair of swan necks, head light, signal lights etc... It will get the full Gregory Bender wiring harness replacement a CEV fuse box and all the other little parts needed. The engine was supposedly rebuilt with a new crank, bearings and Giladorni kits (we shall see?), forks look good, calipers are new, the list goes on. I have a fresh pair of 750S tool boxes and a gas tank already painted in the green scheme.  The project will get going as time allows.

Cheers

Jim

Nicely done .............. I look forward to viewing some of your machines in person one day.

Ciao.

I spoke with Fast Industries (the Canadian branch of Millennium) in Manitoba, after a short discussion I mailed off the original cylinders and two NOS pistons, they will plate the bores and size them to the pistons. I also sent them the heads, new guides, valves and springs plus the retainers, spring shims and caps, they will grind the valve seats and shim the valve springs, and I asked them to deck the heads while they are in there.

Jim...

When Millennium sized the bore to the pistons what clearance did they target?

I just boxed up my V7 Sport pistons and cylinders to send off today to send off for replating with NiSiC.

I think a reasonable value is 0.0015 - 0.002 in based on the following below.  The LM4 is the only NiSiC bore for Guzzi that I checked out but I also found some air cooled cars (Porsches) that use this range with NiSiC.

I went into some factory manuals (thanks to Greg Bender’s fantastic web site) to do some research into piston to bore clearances and wanted to share what I found.

V7 Sport – chrome bore
Cylinder               82.500-82.006    Min  36 um  ~ 1.5 “
Piston                   82.458-82.464    Max 48 um ~ 2.0 “

850 T – chrome bore  (also LeMans II)
Cylinder               83.000-83.006    Min  26 um  ~ 1.0 “
Piston                   82.968-82.974    Max 38 um ~ 1.5 “

850 LeMans – CI sleeve
Cylinder               83.000-83.009    Min  55 um  ~ 2.0 “
Piston                   82.936-82.945    Max 73 um ~ 3.0 “

G5  – CI sleeve
Cylinder               88.000-88.009    Min  71 um  ~ 3.0 “
Piston                   87.920-87.929    Max 89 um ~ 3.5 “

LeMan IV -  NiSiC  Cali 1000 the same
Cylinder               88.000-88.006    Min  26 um  ~ 1.0 “
Piston                   87.968-87.974    Max 38 um ~ 1.5 “

I need to nail down a value this week.

Not sure, I sent them a new pair of pistons and rings I got from Harper's and they sized the plating to match.

Jim,

I just got done spending a good part of my Sunday afternoon and evening going through the whole tread.  Awesome effort and the end result is stunning.  If I understood correctly, you were showing the bike in a local show...  I wish I could attend to see it in person.

This thread is better than pretty much any other Sunday entertainment I could have come up with! 

I look forward to your next adventure.

[mantaray]

Once again a nice job Jim .......Congratz

Thanks Raymond!

I have really enjoyed bringing this fine bike back to full health and I even controlled my urge to not repaint the tank and side covers.

On to the 750S project......

[canuck750]

I have worked out a deal to sell the S3 back to its original owner who will give it the love and care it needs but more importantly ride it regularly!

I finished the rebuild over a year ago but today for the 1st time attempted to fire it up. I set the point gap, set static timing, fresh oil, gas, charged a battery. Pulled up the choke levers, turned on the gas and with fingers crossed hit the start button, a couple revolutions of the starter motor and VAROOM! it fired right up and sounds great. I ran it or a couple minutes, let it cool down and checked all the oil and fuel lines, no leaks. Started it again and let it run for 10 minutes with a big shop fan keeping the motor cool. Drained the oil, replaced the oil filter and tomorrow I will re-torque the heads and set the valve clearance and set the timing with a strobe.

It feels so damn satisfying when a rebuild fires up and runs smooth!

[twowings]

What a great story! The Circle of Life... hope the owner gets many happy (s)miles out of her

Hi, Jim.

Luca told me last weekend that you guys had reached an agreement, and he was so excited about the bike coming home.  I'm really glad it worked out this way!

Well done!

One of those things that was meant to be.

I had to resolve an electrical gremlin last week, duff starter button, I had a brand new one in my stash, once fitted all electrical problems resolved, otherwise its like it came out of a coma after major reconstructive surgery.

I hope Luca rides the wheels off it, I am looking forward to his comparison of the before and after now that it has Ikon shocks, FAC damper, progressive springs, new tires and brakes and the B10 cam.

Sounds good!   Will be interested to hear what he says, as well, and maybe we can compare will my 950S tribute if I get it done. 

Hope it gets here soon so I can see it.  Planning to move back West someone soon.  Maybe we'll take the northern route and stop in to check out your collection.   

Cheers,
Shaun
