ST2 Starter buggered, any others fit?

**nel5on** · 22 Jan 08, 09:06 PM

My St2 1999 starter is buggered. Yes even the smell escaped.
I was wondering....(I work for an Italian compay) what other bikes use the same starter?
Will others fit, I guess the part number is Ducati only, but guess the motor will be main stream.

I only bought the bike Sat gone (no blame on Seller, who could know) but the starter went tonight, like wires and stuff gone inside. Wheres the best place to source another one? I'm not keen on buyin new.

My first Duke and I just want to ride my new toy....Sob,sob,

Cheers
Nelson

Youre lookin at 20£ish for a new solenoid, either ducati oe (mitsubishi and others) or pattern so thats not too bad. Aprilia's i think have the same stuff but i'm not 100% sure.........lots of japanese bikes too! I know that on the 900ss you can get a replacement solenoid that's from a honda superdream from electrex world! I know from my experience with ducatis that the solenoids do get a hard life (S THEY DO AN APRILIAS)

Thanks Mark,

It's not the solenoid in this case, um.... well could be as well now, but by removing the starter brush cap, some insides fell out, some magnets, wires and other stuff. Being no Ducati expert I guess this is buggered.

The part number is Denso 128000-6050 or 270-4001-1A after some research I've found they are on most newer Dukes, but belive they have also been improved, so wonder what the improved part number is?

Can anybody help me get back on the road?

Cheers Nelson

Basically any Ducati that hasn't got a testastretta engine, bar the 998, will have the same starter motor as your ST2.
The "improved" unit that went into the 999 and 749, and is used in the new SBK's is more than just the motor. The starter gear runs different ratio's. It's not just a motor change. You'd need the idler gear, sprag gear etc. Even then, depending on the flywheel, it may not work as your bike is on the year that changed from 2 to 3 phase.

No specialist knowledge, Nel5on, but I googled your partnumber and came up with this
which indicates that the same pn is used in a 1994-1996 600SS. He seems ot be asking for 129 Euros for a used one....85-90 quid...not cheap....

Hi All
I've got it in my mind that a Suzuki GS550 starter motor has the same internals. Steve (Imola Duke) replaced his. But I may have been hallucinating.

As mentioned elswhere most models have the same starter motor across the range. Nelson, where have your magnets fallen out from? the starter body? I've got a few odds and sods here that could possibly help you out. If you p.m. or email me at porcamiseria@blueyonder dot co dot uk with whats up i could probably help you out, rebuild it and get the beast going. Its a bit of a fiddle getting the end cap on with the brushes but nothing like rocket science, just a bit of patience.Alternatively have a look on ebay... a decent used starter is around £80ish

Sorry to hear about the starter problem.

Got to expect some teething troubles I suppose.

The cluch fell off mine an week after I bought it! But that's a different story...some back street bodger had replaced it!

Sounds like the starter's pretty shafted!

Just a thought, but when you replace it be sure to clean up the the black 2 pin connecter that feeds the switch current to the solenoid and check it is not a loose fit on the solenoid. When this plug gets corroded or loose it can cause the solenoid not to work...I know it happened to mine and many other Ducatis have the same issue.

The solenoid aint always fu**ed! A bit of cleaning up of the plug and adjusting it to fit tighter along with some contact grease can work wonders.

yup, thats right

no youre not hallucinating

**nel5on** · 24 Jan 08, 09:34 PM

Thanks for all your help...It's good to know theres a Ducati forum with helpful members.

Replaced the starter, but the Solenoid has gone too, so will try and pick one up soon. Starter works fine if I bypass the solenoid, so a bit happier now.

I just want to ride her again.

Cheers

Nelson
(at least my first post wasn't a problem issue!!!)

**Steve GD** · 25 Jan 08, 06:31 AM

Good news, Nelson...let us know how it goes!

**nel5on** · 25 Jan 08, 08:33 PM

Took the bike out tonight.... she ran a treat, Batt was a bit flat, slow on the starter(on charge now)
Love the Dutz fasteners, all Fairing on in 10mins

I find I'm running slower into corners than I did on the BMW, but guess I just to change my riding style.

Now keen to meet up with some others to ride....

I feel proud to own a duke, I feel like everybody is looking at my bike..... I like it.

Thanks for all your help guys

Just got myself a 1997 ST2 a month ago and it's been getting harder and harder to get started until at the weekend I was forced to bump start it. Unfortunately when I had stopped the engine and tried to restart it I couldn't get the starter motor to do anything. I press the starter button and not a squeek.

I've checked the fuses in the left side of the upper fairing and no problems there.

Any ideas on how I can trace back the problem to diagnose it? I don't want to replace the starter motor to find out it was something simpler (and cheaper!) causing the problem.

**nel5on** · 27 Mar 08, 07:53 PM

Use a jumper lead from the batt to the starter, bypassing everything else, that should tell you if the starter is buggered (if good, it will spin up /normally or fast)or if its the solionid(sp) or started circuit...Make sure the bike is out of gear and on the center stand!!!

Got try it?
