750S The Build is Done

[swooshdave]

Have you checked the run out on the rotor? Powdercoat may be uneven. For example with Lockheed rotors when they grind them flat you want the rotor face parallel with the mounting surface. Very common with brake rotors.

Powdercoat is thick and can compress as it ages. Rotor may loosen over time. Please check periodically if you leave it.

Regular paint is relatively thin compared to Powdercoat and you can get away with a very thin coat of rust preventive paint.

Good points, probably good practice to check the torque on the rotor bolts annually. I had the rotors ground by Truedisk,

they do a fantastic job and are very reasonable

Love your build, Jim, Thanks for sharing it . +1 on Truedisk. Tom does a great job. He has done a LM 1/3 drilling type pattern on  a couple  sets of mine that looks great in case anyone wants something more Guzzi-ish like on their rotors

If you're going to spend the time getting the discs ground perfectly parallel I wouldn't trust Powdercoat to be as flat.

Check the runout.

Well you got my curiosity up I am going to measure the run out with a dial gauge, the only thing is, if the dial indicates there is a significant wobble (not even sure what that would measure?) I really will not know if it is the disc or the bearing/ disc carrier. Assuming the dial readings is inconsistent I will probably need to chuck up the disc carrier in the lathe and then measure them not to mention the wheel hub could also be a contributor to run out on the disc.

This could prove interesting.

[swooshdave]

The assumption is that the person who ground the discs made them parallel.

The obvious culprit would be the Powdercoat.

If you have wobble it would be the same if you had a warped disc. Not good.

I am down to the very last items, installed a Dyana Ignition this evening,







So that finishes all the wiring with the exception of the signal light switch, waiting for an original right hand signal switch bracket, and I found a better picture of an original 750S that shows the 850T type clutch perch and a separate bracket for the light switch, again just waiting on a NOS bracket to arrive (thanks again Curtis).



I just gota say once more, Gregory Bender's wire harness kits are amazing!!

[canuck750]

Finally some pretty bits

New repro tank emblems and a repro gas cap to the repainted tank



Original electric fuel valve with a reproduction decal



Only two parts yet to source / fit, the CEV switch brackets, left and right, switches zip tied for now



Checking my 750S part book it turns out the 750S takes the same clutch perch and cable as the 850T

Harry sold me a great Sprint half fairing that I took to the painter to get repainted black, it should look sharp on this bike.

[balvenie]

This is a Great story, Jim

[smdl]

Amazing...

[canuck750]

Thanks Shaun. I think this one is my favourite. Once I get the half fairing mounted it will be pretty unique.

How is your sports car project coming?

Cheers

Jim

Hi, Jim.

Thanks for asking.  The Spitfire is just about back together and ready for a safety inspection.  That should give me a decent driver for now, and I will work on the TR250 restoration over the next few years.  However, that won't happen until I first complete the 750S tribute.  Should be getting back to that next month, and can't wait.  Your updates serve to frequently remind me of how important that is to me!

Nice car, and a metal bumper era to boot!

[canuck750]

After the better part of 9 months the 750S rebuild is done.

The last details were the electrical; switch brackets came via Ebay - from Eurotrash, now the switches and controls are correct









Fitted a Brown side stand (thanks to Cam for getting these into production), they work great and they DON'T collapse





Now to fill the crankcase with oil, fit a battery and see if it starts, hopefully I get it fired up on the weekend.

Bravo...your attention to detail is inspiring and appreciated ..
Soon you will be riding , hopefully before the snow fly's

Jim, I have been thoroughly enjoying this build, and have learned heaps myself from it.

The end result is truly outstanding. A gazzilion thumbs up!

[Nolan Woodbury]

Well done!

[Aldo]

Excellent job, looks stunning! 

[Demar]

Congrats Canuck, that's a beautiful bike. I hope to restore a V7 Special some day.

Hey Jim, it looks like that Brown stand is hanging too low in the retracted position.  It should be parallel to the flat pipes on the 750S/V7 Sport.  I've heard of another one (Charlie's customer) that was the same way.  It appears they got the angle wrong when welding the modified mounting plate.  I would send it back to Boxerworks to get it right.  Unacceptable for that price.  Here's mine (first Guzzi prototype) on the Sport....

[Dukedesmo]

Very nice, well done. 

[Fuzzy]

Wow...just...wow

Come to think of it I thought it looked strange, age is creeping up on me! I will take it off and send it back as you suggested. Thanks for catching that.

Cheers

PS 

to the WG Community - Thanks for all the encouragement and advice along the way, without this fantastic web site and its many, many knowledgeable people projects like this would not be possible.

They'll tel you that there's something different about your bike or that you're installing it wrong. That's the response I got anyway.

One question, Jim. Did the 750S have a "shroud" around the warning lights like the V7 Sport (the forward portion of the housing had a raised "lip" around three sides)?



One suggestion: you need one of the plastic covers to hide your solenoid. :-)

[Cam3512]

Send Nathan those pictures.  There's really no wrong way to possibly mount it.  They know all Tonti's are essentially the same.

Ian Fallon's book on the Sport / Le Mans claimed that the 750S came with either the browed or flat idiot light bezel.

This picture of a 750S in Italy shows the brow, it also indicates the earlier throttle, which is probably the correct one but I had a couple of the later Tomaselli types laying around.



I chose the non brow bezel to be distinctive from my V7 Sport, I believe either is correct.

I have not seen the solenoid cover on pictures of the 750S, was it a stock item?

No, but sure hides a lot of "ugly".
