Looks like a front wheel spacer to me.Didn't notice it was tapered. Don't think I have seen that on my 1979 T3.

This thread is great, like buying a new bike without spending any money.

I love the open area behind the airfilter.

I remember chatting to the Rotary Norton team at the Isle of Man TT races who mentioned not using silicon fluid on their race bike.
Their theory was the silicon is too slippery and caused the pads to drag on the disc - a bad thing on a race bike.
Disc brakes automatically adjust as the piston slides through the square section seal until the pad makes contact with the disc. The seal distorts as it attempts to grip the piston, when the brake is released it is this distortion that pulls the piston back slightly to allow the pads to clear the disc. It was the adoption of the square seal that finally cured the dragging problem early disc brake designers faced.
No doubt this 'slipperiness' problem can be overcome by the careful choice of seal dimensions, perhaps having it grip the piston tighter, but may cause problems with brakes not designed for silicon fluid.

Thanks MArkS,
I really must buy a copy of Guzziology. Recent cold weather and refurbishing the bathroom have put the project on hold for a while, just long enough for me to loose the bits I collected no doubt.

Years ago I remember riding from Germany to England and on arriving at the
DutchNetherlands border was greeted by the customs agents who enquired if I had any sugar or non-european rabbits! It turned out that when there were political squables between them and Germany, the customs were told to make things difficult for anyone entering from Germany. I assume the question was their way of playing along and reflected their sense of humour. However I have often wondered since if non-european rabbits eat sugar? -
Being a spectacle wearer I like Flip-up helmets, I have not noticed any real difference in weight. Look at the locking mechanisms, some have plastic latches - probably wont last too long. I have a cheap RS-V121, ACU approved, £100 including Bluetooth intercom. I feel there is probably very little difference in the injuries you will receive in an accident if the helmet costs £100 or £500. Most of it is the price of fashion and exclusivity.
Best way to protect your head is to not crash.

I think the earlier 5 speed bikes had a narrower rear wheel, The later 6 speed bikes have a wider 180 section tyre so the alignment of the gearbox output shaft to the drive shaft has moved out to the right to clear the new wider section tyre. This may be why there is a difference in access to the forward Universal joint.
Its more to do with the wider rear wheel than the short/long frame.

So are all Le Mans versions long frame?

The Netherlanders can be described as one of the true expansionist nations. At the rate they are reclaiming the North Sea I am convinced I shall awaken one morning to find Britain merely an island in some giant Dutch lake. Still have to take a ferry to get anywhere though.

Thanks for listing the connector, as you say I need the RC ecu to run closed loop. I picked up a used LC-1 lamda controller and an AFR gauge recently and have been riding around looking at the results, tend to wander around a bit at present but quite interesting.
-
That is very kind, I think I have all I need at present just waiting for the double banjo pressure switch now. Thank you for thinking of me though.

For interest sake my 2004 (2003 built?) Rosso Corsa has an IAW15M,C7 and is labelled MG V11 LE MANS MY 02, not sure if that is the most up to date ecu for that bike.
I obtained an IAW15M.A8 labelled DUCATI MONSTER 900 which I stripped to build the My15M including robbing the main connector. I am now considering getting another connector and resurrecting the little beast. This may give me a spare to play with.
Although a 'non lamda bike' my wiring loom has the connector for the O2 sensor so it was easy to connect the sensor up to the My15M.
You can now see why I was asking if I can make the old Ductati unit operate closed loop.
Good luck with project which I suppose not suprisingly reminds me of the DucatiDiag software I have also been playing with.
The truth is however my bike runs fine with the original ECU, I am just tinkering about - I have now got the My15M to run as well as the original except for slower starting.

Many thanks, I found and used the button. We really need to support this guy.
Does anyone know if there any actual differences between the 'with lamda IAW15RC' and the 'without lamda IAW15M' ecus other than the software, in other words can I reprogram an IAW15M to act as an IAW15RC? Also can we reprogram the more common ex Ducati IAW15 ecus to run on a Guzzi?

I think you are talking about the device that senses how much weight is on the rear wheel via a link rod from the swinging arm. I will look into these aftermarket proportioning valves.
For the moment I am going to keep things as simple as I can by simply running a single line from the hand master cylinder to the RH disc and run a second pipe from the rear master cylinder to the LH front disc. Then depending on how it rides consider adding the proportioning valve.
I am waiting for a replacement brake switch for the rear master cylinder that is long enough to accept two brake-pipe unions.
Others have told me to look out for very short rear pad life.

Please give a bit more detail about the 'hydraulic height adjustment' Lubho. (don't know why I cannot correct this tiny font !)

Ah yes the Munch Mammut. There was a brave man.

Thanks for pointing out the valve actually biases to the rear and not the front wheel.
The standard old Guzzi T3 system works well, you can brake hard at speed with the foot brake with bike feeling very settled even hands off, pulling on the hand lever markedly increasing the braking with plenty of feel. The system is particularly good in cold weather with heavy gloves. As I understood it the size of the discs were chosen to give the correct amount of braking bias. I appreciate a racer may prefer the convential setup when at the limit but I am on the heavily policed UK roads.
I like the idea of ABS, great in my car, but perhaps a little ambitious to fit to a V11.
My intention is to convert to a system similar to your old Gold Wing ie., foot front and rear wheel with the hand lever adding more braking to the front. Never having ridden a Gold Wing I can't comment on the rear wheel locking problem, never happened to me on the T3.
The only time the linked braking has given me trouble is on very slippery off-road descents where its nice to be able to lock the rear wheel. The V11 is a little ungainly for that sort off work so hopefully won't be a problem.
-
An attack of basal joint (thumb) arthritis leads me to want to convert my '04 V11 to the linked braking system as fitted to the conti models.
I have a T3 and find it a very good system, now my T3 does not have a compensator valve as such, merely a simple manifold to direct the fluid equally to the LH front and rear disc and to mount the rear stop switch.
I also have one of the valves from a California - don't know which model - which does appear to have moving parts apparantly to bias the fluid to the front disc.
Does anyone know more about this system, which version would you fit.
There are of course the additional problems of the master cylinders now being the wrong size.
Any advice. Master cyl. part numbers, donor bikes etc?

Since the new version of the site I find many posts have random words hi-lit and underlined. I click on them thinking they are relevant to the post but get led off to strange websites offering beauty advice etc. (although I do need it...).
Is this a site problem or a setting at my end?

Saw one on the Guzzi stand at the Bristol Classic Bike Show this weekend (strangely actually in Shepton Mallet). Did not look so huge as I expected, probably smaller than the new Triumph Rocket 3. Build quality looked good but also looked a bugger to clean. Definitely reminded me of the original Cali with the black and white seat. Did not like the finned, polished and laquered rocker covers - too square and reminded me of those small Korean choppers KMCO, KYGEL or whatever they are called. Still not beyond the wit of man to have replacements, similar to the original round barrel covers, cast I suppose.

I just took the MyEcu data off the SPORT.ECU file supplied by Cliff as an example. I understand that the ambient/oil temp and barometric pressure modify the timings actually sent to the injector. I assume the IAW15M must do something similar. I need to study how to get the two maps displayed as a 3d graph.

So if we look at the view of the ‘how the editing works’ we see the top left cell has 84.14 @8500 = 195
I assume this means Wide open Throttle = 84.14 degrees and that at 8,500 rpm we deliver 195.0 fuel .
What does the 195 mean, is it a quantity or weight of fuel, is it the injection duration? I ask as a typical figure for the MyECU would be Wide Open Throttle at 8,143rpm = 10368 micro seconds injection duration.
I am trying to see how the IAW15M ecu map compares with the MyECU map.
Many thanks for your excellent work, I can give you loads of tips on the best way to cut your knuckles when heaving on spanners or setting light to things while welding but am a bit slow learning this virtual stuff.

What with the excellent forum and now the diagnostic software.....wonderful. Donation sent.

Jokes
in Special place for banter and conversation
Posted
Being a bit fed up with most of the men she has dated, Thelma reluctantly accepts an invitation to dinner from a new guy in the area. It all goes splendidly and his conversation interests her, they have several pleasant dates when he invites her back to his flat. As it has all gone so well she accepts, he is attentive and polite, "Can this be the one ?" she wonders. The evening progresses and soon they are snuggled up in bed, the sex is great and she lays there feeling secure.
She notices three long shelves on the wall with rows of teddy bears, big ones on the top, middle sized on the middle and small ones below. " He must have a sensitive nature to collect so many teddy bears and to arrange them so neatly" she thinks, again they have sex and it is better than before.
"Was it OK for you ?" she asks.
"Yeah great" he replies, "Take anything you want from the middle shelf".
