Alternative ignition coils

for Ducatis with Kokusan ignition

NOLOGY: ProFire PFC-30S (152 051 300)
Andrews: CW140403
Dynatek: DC3-1 (the green ones) or DC10-1 (the black ones)
Dynatek miniature: DC3-3 (DC3-2 = set of two coils)
VOLT-Tech (VTwin Manufacturing) (VT No: 32-0484, orange)
Daytona Twin Tec Mini Single Fire Coils (p/n 2006)
Andover Voodoo Single Fire Coils (voo-021 = 3 ohms, voo-023 = 5 ohms)
original coils of carbed (not fuel injected!) Monster/SS (primary 3.8-5.2 ohms, secondary 10.8K - 16.2K ohms, plug cap 5K ohms)
Silent Hektik: MotoCoil (recommended only for use with Silent Hektik ignition module as coil resistance is 2.7 ohms)

The P750 (California model) with Marelli Digiplex ignition uses Marelli BAE 209BK 7J coils. These have about 0,35-0,4 ohms resistance. Same as the ones of the 906.

note: listed NOLOGY, ANDREWS, DYNATEK, VOLT-TECH & Twin Tec are coils with 3 ohms primary resistance (the Dyna DC10-1 are 5 ohms). Using coils with lower resistance than 3 ohms can lead to ignition module damage.
(The 907i.e. being fuel injected and with a different CDI unit uses lower resistance coils. See 907ie FAQs)

Starter Brush Replacements / starter rebuild

In case the starter motor is starting to act up never hit it with a hammer ! On the inner side of the starter housing there are magnet plates which can break. Also if the brushes are worn they could fall out of their guide ruining the rotor.

The brushes are 6x9x12,5mm.

Also used on:

Kawasaki ZX750 (1996-2003) & ZX900 (1994-1997); part numbers: 14079-2055 & 21169-1058
Honda; part numbers: 31201-HA0-004 & 31231-ZA1-003

http://forums.ducatipaso.org/viewtopic.php?f=1&t=2573

http://forums.ducatipaso.org/viewtopic.php?f=2&t=4449

http://forums.ducatipaso.org/viewtopic.php?f=1&t=4870

http://www.electrexworld.co.uk/smbk175- ... 221-0.html

The bearing on the power take-off side is a 6002 (verify with your original if it is a RS, 2ZR or other).
On the rear there`s a low maintainance slide bearing with the measurements 10mm x 14mm x 10mm (Id x Od x height).
The oil seal is a BASL 15-24-6 (or 5, manufacturer Simrit).

In case the starter motor turns but you hear strange noises from the engine and the bike won`t start after replacing the brushes it could be the starter was not assembled correctly making it spin in the wrong direction. The noise comes from the starter sprag clutch which is then also running reverse (which can damage it). Looking at the left side of the engine (alternator cover removed) the starter pinion has to turn counterclockwise. This is the same rotating direction the starter sprag clutch will lock.
There are marks on the front and end cap of the starter motor as well as on its center body which must align. While there are line marks on the end caps and the front (drive shaft side) of the starter body its rear mark is a square and on the opposite side. The marks of the rear cap have to align with this square.
In case you replaced the starter sprag clutch, too you should verify if it`s an incorrectly assembled starter motor or a reversed mounted starter sprag clutch.

Instrument Cluster Vibration Damper Alternatives - Cheap

Post by Desmo_Demon »

Instrument Cluster Vibration Damper Alternatives - Cheap


From May of 2007....
http://forums.ducatipaso.org/viewtopic. ... 992#p12992
Public Service Announcement - For future reference, the vibration dampening mounts for the instrument cluster have an M4x.70 thread with each thread section being 3/8" (9.5 mm) long and the rubber section 3/8" (9.5 mm) in diameter and 3/8" (9.5mm) in length. I surfed through McMaster-Carr's catalog and the M4x0.7 with the same sized rubber or neoprene section but 1/2" (12.7 mm) threaded sections are Part #9376K111 and $1.50 each. This means that you can buy this part MUCH cheaper than the OEM, but you will have to cut 1/8" (3.2 mm) off of the threaded section that will go into the instrument cluster so you don't break the housing (it is a blind hole). I hope this helps save someone a few bucks in the future.
Edit - Price on June 18, 2021 is $1.77 each for part #9376K201 listed as the one with the metric thread....
