Hi all, hope everyone’s doing as well as can be. After a long time of lusting over the 90s Supersport and with the help of lurking here for a few weeks I think I chose the right bike for me. It’s a 92 900SS, 23k km (14k mikes), and it seems lovingly maintained, which by the opinion of forum members here was the way to go. I had the option of and looks at a 96 ss/sp for about 2,000 less but it had no maintenance history, he had it for a year, he had no idea how long ago the belts were done, it had worn tires, needed new front pads, it showed corrosion in a lot of places, it was leaking oil out one fork, and when he started it up it was only firing on one cylinder at time’s, and then wouldn’t stop with the kill switch!
The 92 I purchased has fresh fluids tires brakes and the belts were just done. He was also kind enough to provide me with the following list of parts on the bike :
Barnett Clutch Plate Kit Item # 279650
Barnett Clutch Spring Kit Item # 279659
NGK Racing Cable 8515 90deg. Cover - 100cm - CR5
Dynatek Coil - 12v HD Single Output - 3 OHM - DC3-1 Item # : 212817
Ducati 900 SS SL 1993 Front Or Rear Red Round Billet Race Foot Pegs
Flennor timing belt 70x18 set
JE Piston Kit 11.5:1 Standard 92mm Bore 157597
Niche Cycle Carb Rebuilt Kit
Ducati cylinder head / top end gasket kit. Ducati part-no. 79120031A; replaces 02079
Corbin seat
He included the original exhaust in the sale, which is pristine, the original foot pegs, original levers, and the original seat with pillion rest cover. He believes it’s the original paint and parts - although it has an alum swing arm, adjustable showa forks, a cr fairing, which my understanding from lurking all came later than 92 so I’m a bit confused
There are a couple of reported “issues” one is that the bike is “cold blooded” as the PO put it. He said it takes about 10 minutes to warm up to a safe idle and that you’re best off just getting on and riding it. I have not had a chance to ride it and won’t until my young son is at his moms next weekend. Anyway - Upon start up with a fully engaged choke, the bike needed some additional coaxing with the throttle and slowly settled into about 3000rpm. My experience with bikes is that once that happens you can pull the choke back so I set it back a notch and it cut out. I tried a few times fir about five minutes but never got it to idle without it cutting out on its own.
The other issue is that the carbs need adjusting.
It has Supertrapp cans original headers and the po said it was running rich on 150 main jets so he said he went back to stock (which i think is 135) and said that the “carbs need to be balanced now” .
My questions to anyone kind enough to help out - is it normal to have these cold start idle issues, is there some connection with the change in jet size, and should I take it to an experienced technician for the carb balance and to look into the starting/idling before riding it - or is that something that a somewhat experienced bike owner can play with? I’ve lurked and it looks like the whole fairing has to come off to do anything with the carbs, for starters! Also curious about the “original” parts. Anyone’s help is greatly appreciated!!
