The Ignitech makes a big difference - it allows you to set up a proper ignition curve (rather than the savage step on the Kokusans) just where you want it - at the low end of the rev range
That's right, it's the Kokasuns which are the problem. I also have the exact fit coils from CA cycle works, the MBP? collets and large earth cable for better starting.
It's good to hear plenty folk have the same mods I'm planning FCRS CA Cycleworks coils Ignitech Hi comps. Dyno time
Given a decent method of controlling spark generation (i.e. Ignitech), is there any real need to change the coils?
Well, this was all done around five years ago now, the ignitech will give you a smoother curve and is also totally programable and if going the HC route will also enable to change your ignition timing. The coils will give you the stonger spark.
Agreed, but if the coil generates a strong enough spark to ignite the mixture ( which the standard one clearly does), what's the actual benefit of 'more' spark?
I can't remember, TBH but if you go onto the CA cycleworks website you can read all about it on there.
I've fitted the CA Cycleworks coils. Very pleased with them, instant start and better, smoother low rev running. Worth it just for the instant start, no more of the engine turning before it fire's. It really is, press the starter, boom (sorry), instantly its running. I've also fitted a thicker earth and positive leads from the battery. The original thinner cables can't really carry the current.
No modification needed, the IE uses the same frame. To the best of my knowledge, it is more or less, a carby bike with new bodywork and a fuel injected engine.
Hmm. You've set me thinking again. Mind you, starting is pretty good anyway - I've got uprated starter/battery leads, which do make a huge difference. Also, to complete the set (although I doubt it makes much difference), I've replaced the small earth lead that goes frame to crankcase near the the footrest, with one from the head direct to the battery.
If you think the original ignition was never cutting edge, the exact fit coils and ignitech unit should make a huge difference. If it made no difference having a stronger spark why do people have dual spark heads?
Not trying to start an argument, or criticise, just speculating that if the standard coil ignites the charge with (say) 15k volts, then its done its job, and there's no need for a spark at 35k volts. The CCW site makes no claims (that I can see) about improved performance at all. That's a different issue to the Ignitech which makes a huge difference ( I've had mine fitted since 2008) cos the standard igniters don't actually have an advance curve - just a bloody great step.
The benefit of these coils that can deliver higher voltage sparks are as I understand it are the ability to run a larger gap at the plug, which helps with the burning of the fuel. The most noticeable effects can be felt at the lower end of the rev range with less lumpy running, and jerky throttle response.
If it is, I'll be happy! Different part numbers for left and right, still, it's possible ... Edit: Nope, they are very different items.
Sorry about that. Theres a new pair on eBay @ £40.49. I dont know how to do the link thing but the title is: Ducati SS 620 750 800 900 1000 exhaust hangers brackets (pair) *NEW* 1998-2007
