Thanks for that link, Boris. A fascinating article. That guy really seems to know his stuff. Well written too.

Having gone from lightweight to heavy, I can personally vouch for everything he says, except I haven't experienced any rear wheel lock-ups as my riding style is too sedate for that! I did, however, predict that might happen, so it's nice to know I wasn't talking complete rubbish!

Having read and reread Luddite's excellent piece and also exchanged PM's with him, I decided to try the O2 sensor eliminators, I've already junked the exhaust valve and catalytic converter (by installing a Remus Hypercone) and I've changed to a 14 tooth sprocket.
Fitting was relatively straightforward and I had a chance between showers to get 80 miles on the bike today, mixed town work of 30 mph and some good open road blasts (70 + !).
There is a positive difference, it doesn't hunt as much on small throttle openings in the low gears, it's still not the most pleasant experience and I certainly wouldn't want to be city commuting on it.....ever!
On the open road it pulls like a train and has lost the occasional "cough" as it picked up on acceleration, I haven't noticed the flashing engine light on rapid downshifts.
But after sitting for half an hour it was reluctant to start and when it did the engine light stayed on. I stopped for fuel and it started OK, but still displayed the engine light. I gave it the berries for around 15 miles, stopped and cut the engine, restarted and the light stayed off.
On my outward run , of around 40 miles, it would not return to normal tickover (1200 rpm) but wanted to tickover at around 2200 rpm , not good for traffic work. But it has done this in the past and is probably another "glitch" ( all sensible ideas/suggestions gladly accepted !)
Luddite has also suggested changing plugs to a different spec iridium and that will be my next step.
I'm basically a little happier and will decide before putting the bike to bed for the winter if I'm going to get the ECU reflash or use the cash to upgrade the suspension.

Crawsue, speak to Neil at Cornerspeed ( http://cornerspeed.co.uk ) he does a postal service for the Rexxerr Flash, will sort out your engine lights and all your other fueling issues, just make sure you get a performance air filter and mod your airfilter bix lid to allow more air in.

Crawsue,
I’ve Very recently fitted the full mwr air filter setup including power up mod. It’s another incremental improvement imo.

My Ducati specialist mechanic (Tyler at north motorcycles) recently done my 15k major service. He said it’s running beautifully and the mods are a massive improvement over stock.

Let me know if you’re going down the air filter route and I can give advice or even pop through to you and show you how to do it.

jonzi · 17-09-2018, 08:24 AM

Did you get a remap after the MWR filter?

Ron1000 · 17-09-2018, 09:41 AM

No I’m running a power commander v with auto tune. It’s just been checked by north motorcycles too as part of its service coincidentally. The mechanic Said it’s running beautifully

crawsue · 17-09-2018, 02:53 PM

Cheers for all the advice, Sunday was a washout here but today gave it another 80 mile run to Largs, no starting problems or fast idle problems this time, still a bit "snatchy" in 30 mph limits, but it's liveable with.
It seems to return to idle in two stages....pull up at a junction from a faster speed and it initially drops to around 1600 rpm, then after 2 - 3 seconds it drops to normal 1100/1200 rpm.....are these things "fly by wire" ?It's strange....like an old Monobloc with a sticky slide.....for those over 60!

I'm sure I've seen a post about this! It's an easily curable problem but I can't remember sorry. Do a search for it. maybe ducatiforum.co.uk

Found it here https://www.ducati.ms/forums/42-mons...high-idle.html

And here. https://www.ducati.ms/forums/241-tec...died-mine.html

Have you tried the throttle position reset trick?

Start the bike without using any throttle and let it idle again without ever touching the throttle. Let it get it to 3bars in temp then turn off.

This might help the bike slightly.

Also they are definitely not ride by wire.

I think you have to disconnect the battery before doing this. It dumps the adaptive settings from the ECU.

Ron1000 · 17-09-2018, 10:12 PM

Ahhhhhh interesting

The stock (and even the Ducati Performance) mapping is still lean at low speeds even after the O2 sensors are removed, which contributes to the "snatchiness". That's where a remap, like the Rexxer ones offered by Cornerspeed, will help as they enrich the mixture where you need it, at town speeds.

Have a look at this thread about ECU resets - it contains everything I could find out on the subject.

Some great info on this thread!

I've also decided on trying the heavier flywheel after speaking to Wilf from Moto Rapido back in the spring. I'm waiting until the bike is off the road November (ish). I still have my dyno readings from when the Ti exhaust went on, so we will have a before and after dyno to see any effect. I'll keep you posted.
