Hi all, long time lover of the DUC's first time caller. I have a 93 750ss/cr, with half fairings. I bought it wrecked the front wheel is bent and the motor mounts on the front are snapped off and some other problems. I talked to a welding instructor he said that the mounts could be welded back on, does anybody see a problem with that?
Also does anybody know where I can find a front wheel for this bike? I have had this bike for several years just sitting in the garage thinking that I couldnt do anything with the mounts.
I have a complete frame ready to swap it into if I can have the motor mounts welded. There are a few other things that need attention but the motor is the main thing im worried about. I was also told that the 750's run really well almost as good as the 900's is there any truth to this statement.
The local Duc dealer told me that the 750's where only imported to the states in the years 92-93 also is this true? Sorry for all the questions.

Thanks Shawn

Sorry may have got excited with my first post and to many questions. Has anybody tried welding on the case's? Any ideas?

Thanks shawn

Pretty much anything can be welded if you can find a welder who knows what he is doing. I don't know about the 750 being almost as fast as the 900, kind of depends what you mean by almost, but both are relatively slow when compared to Jap inline 4s. Unless the front wheel is really badly bent, it can be straightened. I had it done on a CBR 900 RR I used to own and it worked fine. The place was www.framestraightsystem.com. He won't do it if it might not be safe.

I see wheels all the time on eBay, so you should be able to score one of those pretty easily.

I'm about to post a for-sale ad in the Classifieds for a pair of Marvic 2-pc wheels that came off my 1993 Superlight. I will also be selling the engine from that bike.

 

[haulinit]

Thanks for the info guys. I will look at getting the wheel straightened, when ever I look on evilbay I only find rear wheels. Is the 750ss really that hard to find in the states? The ducati dealer didnt want to believe me when I told him what I needed parts for.

Next time tell him your looking for '92 750SS with a dry clutch parts and see how funny he looks at you then!!

That's the look I get!

This is going to be a FNG question but do the 750's have a dry clutch, and or which models do?

-----------------------------------------------------------------------------
MY 1997 [1.146 built]
A number of changes for the bike’s last MY. Bimetallic inlet and exhaust valves (better to suit unleaded fuel); oil-cooler mounted above the front cylinder (like the new Monster, less vulnerable to debris); carburettor heating kit (to cure carb icing in Mikunis caused by long inlet tracts); increased steering lock to 28 degrees either side; fairing with revised (larger) graphics, added air intake (for cooling rear cylinder), internal sound-absorbing panels; more comfortable seat.

MY 1996 [60 built]
Production interrupted so few produced; only change was sound deadening panels in the fairing.

MY 1995 [1,550 built]
Colour changes were the same as for the 900SS (see spec list above), including 916-style gold frame and grey timing belt covers. Showa front fork replaced by Marzocchi 40mm.

MY 1994 [1,008 built]
The introduction of the single-front-disc 600SS saw the 750 get twin-discs. The Showa front fork was given a larger 20mm front axle. Wheels went bronze. Aluminium swingarm replaced by steel.

MY 1993 [2,352 built]
Silver-painted crankcases; bronze-painted frame and new decals.

MY 1992 [2,973 built]
Clutch changed to hydraulic wet; oil cooler and higher primary drive ratio added from the 900SS; red bikes acquired black wheels. Stronger chain-adjuster bolts from frame no. 001210.

MY 1991 [153 built 1990, 1872 built 1991]
750 model released shortly after the 900 Supersport: essentially the small-crankcase engine of the earlier 750 Sport, with Mikuni constant vacuum carburettors, in the 900 chassis. Early models had the same hydraulic dry clutch. Compared to the 900SS Front fork was unadjustable, different aluminium swingarm, single stainless-steel front brake with gold P4 30/34 Brembo caliper; rear wheel was also narrower at 4.50x17”.

I just did a quick search on KBB and the NADA sites and they only list values for '92 and '93 MY's for the 750SS'.
So yeah, I would say they were only imported for those two years.

Hope this answers some of your FNG questions

[haulinit]

Yep, thanks Mikes.

 

[haulinit]

What is the advantage to the dry clutch? What front wheels are compatitble with the 750 ss's from different models I.E. monster?

 

[Joe-B]

Dry clutch: easier to work on, clutch dust doesn't contaminate motor oil, robs less power since it doesn't have to spin in oil. While watching the Brno Moto GP the other day I noticed Danny Pedrosa's Honda has a dry clutch; I bet most of them do. Sorry, can't help with the front wheel question.

[haulinit]

The clutch makes sense less parasitic drag. Im assuming that by getting the parts off a oem dry clutch bike is all you need to do the swap?

 

[Tbarr1000]

I have a couple half fairings laying around if you need those.

 

[haulinit]

Tbarr thanks for the offer but I would really like to go full fairing.

I think it's a little more involved than that.
Just finding one of the 1275 of the 750's with a dry clutch would be a needle in a haystack proposition.(especially in the States). Maybe 900 parts would work, they're all dry, but I think the cases and other parts are different too. The clutch slave is on the left side of the bike on the 9's. I think yours is in the cover?

Wet clutches are alright, at least they're nice and quiet.

 

[haulinit]

I will have to go look as to where the cylinder is at. Quiet so I can someday listen to the music of the exhaust.

 

[haulinit]

I talked to the weld shop he is goig to try and weld it for me so I maybe a lil closer to being able to enjoy it someday.

Cool!

Im assuming you mean owning a 750 and not a 900.

I need a fuel sending unit, know where to get one other then the stealership?

Exactly what I mean!

Not sure about the sending unit, I would think all the carbies are the same though.
