Posted this on the Yahoo board, but thought I'd check here as well. Just took delivery of the 750 America that was at the Mecum auction in Monterey. It is a 76 model that under the dirt and grime has a grand total of 5500 original miles. It is fitted with 32mm Dells (the stock 26mm Dell’s were also included along with the original air box, manifolds, etc.) and what looks like Magni exhaust (the carbs and exhaust were installed in the late 70’s, so not sure if it came from the factory spares?) It also came with the standard chrome pipes and black and chrome mufflers that had obviously been sitting on a shelf for a long time. It has wire wheels with drum rear and dual Scarab discs up front. The bike was last ridden in the early ‘80’s by the previous owner (confirmed with him) and has been sitting with fluids drained ever since. It was obviously stored indoors as the finish on the chrome and paint is in amazingly good shape for having sat with little attention all those years.

So, having worked on a variety of ‘20’s to ‘80’s exotica (and not so exotic) for many years along with a few more recent two wheelers, I thought before I dig in too far, I’d ask the group for their collective wisdom on where to start and what to do to get this beast running again. I have a factory workshop manual, but no spare parts book. I definitely need to rebuild the original Scarab brakes and it needs a variety of small bits (does the club have access to consumables? How does one actually join the "Club"?), and possible handlebar switch assemblies. Anyway, advice welcome.

Thanks.

Wow...congrats....there are several members here with connections for spares and such. Pretty much a;; overseas (UK?)
By introducing yourself you have joined this "club"...but there is on in the UK that you need to get connected with if I am not mistaken.

And we all love pictures!!!!

Pics added. I think I'm going to run it without the fairing for now. The engine is just way to cool to be covered up :)

Thanks.

Could not agree more, absolute shame to cover up that engine!

It looks :mouthwate not much I can say is there???? :laughing:

I guess it had a bar end mirror on the left judging by the 'hole' there - it seems a shame to put mirrors & blinkers on it but alas we live in the real world ;)

Magnificent Chuck, simply magnificent, may you enjoy it in wonderful health. :)

Cheers

Thanks MVista. Unfortunately, I didn't get the stock front turn signals or stalks (the PO looked, but couldn't find them), so not sure what I'm going to do about that. The turn signal switch doesn't appear to be working properly either, so I may go sans turn signals front and rear for now. Not sure about the bar end mirror either. Pretty sure it had one, and will likely put one back.

Congrats on what looks like a superb bike Chuck. For parts try sending a PM to Dorian (one of the members on here)that's if he doesn't see your post first! He (along with a few others on here) is a mine of useful information when it comes to Cascina Costa bikes.

hi Chuck

Congrats on the bike, they are fun.

Manuals can be found on www.thebikemuseum.com which is also a good source for classic MVs info with quite a few articles etc for the America. If you can't get the parts manual let me know as I have a copy which I can scan onto a cd.

The Magni pipes look great, far better than the originals. Similarly the engine is too good to cover up and like JSM, a Magni 1/2 fairing is a nice compromise and I think enhances the bikes appearance. I'm in the process of converting mine from a full fairing to Magni 1/2 fairing.

From all reports, expect to have problems with the Scarab brakes. A standard mod is to convert the Scarabs to Brembos including braided lines. Mine are great. Parts for the Scarabs are scarce. If you wish to persevere with the Scarabs there is one person who specialises in Scarabs but I'd have to 'find' his contact details. just let me know and I'll chase it up.

I gather you are in the States. The 4C MV expert is Albert Bold, http://www.boldprecision.com/. Albert is great to deal with and can answer all your questions regarding getting the bike back on the road.

As for indicators ... I happily live without them. I think that it was 1975 that they became compulsory so if registration is a problem then fudge the year of manufacture. Besides, they don't really compliment the bike. If you after originals then do some research as I think those for the US models were slightly different to that of other markets.

finally, the MVOGB is a good source for parts (probably the best).

cheers

Nice bike Chuck :mouthwate

If it was mine I'd have the tank and carbs off straight away to give them a good clean-out. Maybe the tank's corroded inside if it's been standing empty all that time? (I used a product called Por15 on my eBay-acquired Sport tank to give it a new inner lining. It's excellent stuff, and the tank still looks as new inside even after four years).

Points will need replacing, and the ignition timing re-setting. (I fitted cheap Fiat equivalents, which I bought from my local auto store :)). The wires in the block-connector beneath the tank can be the source of any electrical/ignition gremlins, so I'd disconnect these whilst the tank was off and clean them up. I'd do the same with the little rectangular connector-box beneath the seat.

I expect you'll be changing the engine oil and filter as a matter of course? - but don't forget the final drive. These can be a weak area on these machines. I use fully synthetic oil in each of these on my bike, and it's run like clockwork for almost five years on it. (I took off the cam-covers over the past winter, and I measured no appreciable wear on the valve train or any of the clearances therein).

Clutch slip is common on these bikes - this caused by the high bottom gear and the bike's heavy weight! - and no amount of cable adjustment seems to help, but it can sometimes be overcome by adjusting its clearance at the engine push-rod instead. Failing this, the UK club might supply you with a set of new (ie. unused! :naughty:) clutch plates. (Join the club here: http://www.mvownersclub.co.uk/index.php?M=14)

The generator light set in the clocks will glow until around 2,400rpm are reached. This is normal, so don't be alarmed :wtf: If it glows thereafter, check the tension of the belts beneath the angine. They can slip! So too, if the starter seems reluctant to turn-over the engine, check the belts. (The battery can be changed for a much smaller/lighter/more powerful gel-type with good results - I've done this, and it's truly been a fit and forget addition. I've never had a problem with starting).

Check that none of the downpipes are fouling the frame just to the rear of the front wheel. This can happen on the fitment of inaccurately made aftermarket exhausts. Judicial persuasion of the pipes before tightening their clamps can alleviate this. (Ask me how I know :jsm:)

It's good to display the engine, I'd agree, but my own bike handles noticaby better with the full-fairing fitted. It's a fairly heavy item, and I can only assume the additional weight over the bike's front wheel improves its balance. Your own may be different? (I weigh only 140lb, so..!)

Good luck with its refurbishment Chuck. Any problems just post 'em up, we'll do our best to help :yo:

Steve,
Appreciate the reply and the link to the UK Club. The tank is already off - the interior is in nice shape although it needs a good cleaning. I haven't attacked the petcocks yet, but they are frozen at the moment so will need some attention. Externally, the carbs look like they are brand new - haven't popped th float bowls yet to start the inspection process. If anyone has modern references for the following consumables, I'd appreciate it:

Oil Filter
Belts
Battery
Points
Rotor
Distributor Cap
Condenser

Other than that, looks like it mostly needs a good cleaning! Will keep the board posted.

Thanks.
Chuck S.

These are some of the numbers I have at hand, Chuck:

Oil filter - Coopers G813 (AC 61, Crosland 521, Mann H6, Knecht SH268, Fram CH 803PL). These are used in the following cars (B.M.W. 1500, 1600, 1800, 1800TI). (N.S.U. Prinz).

Check out these numbers for points: Lucas DSB 446 - Intermotor 22700 - C.I. xcs 123.
Condensers: Bosch (1237?) 330116 - Intermotor 33510 - C.I. xcon 135.

I went to my local auto-store armed with these numbers and the old items I'd removed from the bike, and I came away with the new stuff I needed - although I can't remember exactly which numbers proved to be correct!

Can't help with the rest since I've never needed to replace them, but these items may well be available from the UK Owners' Club. Dorian's the chap who will know best.
