750 Sport restoration project

[Andrew2]

Thanks guys.I only turned the motor a couple of times to see if the starter worked and the motor turned.I'll definately put oil into the cylinders and check the belts etc before I fire her up.

I've thought about putting that extra strut in but thought I would get away without painting it.Looks like I'll be doing it now .

I read somewhere about spacers in the right hand side engine mounts?.What is that all about.
Are there any other Sports that have a rebuild report on here somewhere.Would be interesting to read.
Cheers

I don`t think so. This was one attempt but unfortunately this topic wasn`t continued.

Thanks G,I'll check it out.One question I have.does anyone know of any other bike (any brand ) that has 40mm forks like the Sport.Seeing as my tubes are rusted I was thinking of maybe finding a front end off another bike with 40mm forks and possibly a 17" wheel.If not then I'll try and source some oem fork tubes,although I have read that the standard forks are rubbish.Another optionthat has crossed my mind is a complete frontend from an RGV250 and also a back wheel from the same bike.I've heard this is a common mod.

Keep in mind that a different fork length, triple clamp offset etc will impact handling for better or worse.
Some bikes with 40mm stanchion tubes are ie. some Guzzis (LM4 or early California) or some older Kawa GPZ, early Yamaha Vmax etc. Of course you`ll run into other problems as these bikes have bigger brake discs and use brake calipers with a different mounting hole distance. The axles may be a different size so you may have to change wheel bearings if wanting to keep the original wheels, fitting the speedometer drive could become a problem and you may have to machine the fork legs or some spacers to center the wheel. The original front fender also won`t fit anymore.
Of course problems are less if you find a complete frontend but then you will still have the problem of the speedometer drive and correcting the chain alignment in case you go for different wheels. You`ll probably also need new spacers for the rear wheel then and maybe other bearings for rim and sprocket carrier.
In case the RGV250 frontend is a swap (which I know nothing about, not having a Sport) I wonder if it can be used as is as the Sport is quite a bit heavier. (128 vs. 195kg)

The early models did not have the spacers on the right hand side between the engine and the frame. the later models did, which allowed the used of later 6 speed motors in the same frame. The spacer moved the engine over for better chainline. Judging by the monster offset of that spare countershaft sprocket you were given, you probably don't have the spacers on the right hand side.

As far as forks go, I will gladly sell you my spare set, but you have to pay shipping from California, which won't be cheap.
I am putting on a set of M1R forks on that once graced a Paso, and putting on 17" wheels.
You can search the posts for other comments on the front end. One option is a complete swap for a later model front end, wheel and all, like the one on that 900SS in your garage. Being a Paso man, you know all to well the curse of the 16" wheels/tires.

So your first major debate point in the restoration is whether you stay with 16" wheels, or go to 17"?
In the back its as easy as taking the wheel and brakes off that 900ss and putting it on the Sport. The front is more complicated, but swapping out the entire front end is one option. (not much there to save except history)

Oh, and those rear turn signals are as rare as hens teeth. I haven't seen a good pair on a Sport before, except in the original tests of the bike.

everything but cheap (the ones at Stein Dinse are marked green/in stock)

Just found this on eBay, might be of use if you want to keep it original.

Good luck with the rebuild, mine has slowed down due to finances.

Cheers, Rob.

I think the RGV front end would be strong enough but the springs would have to be upgraded.Also the wheels look the same as Ducati rims.If not there is always a GSXR front end.The only reason I mention these is because they are a lot to get them out here than Ducati front ends.I'm just thinking out loud at the moment and gathering different ideas and of course I value any ideas and input you guys have .

The reason I asked is because it does have spacers between the engine and frame on the right hand side.I'll get some photos tonight and post them up so you can have a look.
Thankyou for the offer for your forks.It's still early days and I will have to have a good think about which direction i will end up going,16" or 17" wheels,original front end or alternative front end etc.I'll keep it in the memory bank though.I know the Michelins are no longer available and have been researching alternatives but to be honest I have'nt seen any that really inspire me to keep the 16's.I do think they suit the bike though.
I'll swap the rear wheel off the SS and see what it looks like.

Thanks Rob,I had a look at that one.I'm in the same boat mate....no money left .I'm going to start with the cheap option...elbow grease .I'll get the motor running then drop it and get the old paint off and new on.Clean the wheels up and powder coat the frame.What are you up to with yours mate?.

Wow, a lot of work to do...

Definately...but it should be fun ( I hope )

Are these the spacers.

Front right.


Rear right.


I also have one on the rear left.


My compliance plate says 12/1988.

It`s painful to see no single aluminium part where the paint hasn`t bubbled from oxidation.
The ground connections don`t look much better. I hope the other electrical contacts do.

Ok, I need to do some measurements to get to the bottom of this spacer thing. I hadn't seen the one on the back left of the engine before.
Also, the spacers look small to me. I'm wondering how many versions of the frame they made now.

I'll measure my spacers to see what I have. Mine is a California issue 1989.

As G. pointed out, with all that corroded aluminum, you will need to spend a considerable amount of time on the electrical connections.
