You would have thought a V Twin motor with its uneven exhaust pulses would work better with no crossover, just down pipes into seperate silencers. The 1969 Triumph T120 Thruxton system had larger diameter down pipes which reduced in diameter about halfway down, cannot recall if it had a crossover - probably one very close to the exhaust ports of course that had even pulses.

We should encourage this, think of the amount of running gear that would appear on Ebay.

Came across this the other day, may be of interest especially as their IAW15M ECU map is designed to improve low to midrange when using K&N pod filters.

I do hope these are American and not English suspenders you are twanging, or do you have a party going on over there?

Don't forget your ten gallon hat only holds a little over eight gallons in the UK.
UK gallon 4.546 litres x 5 = 22.73 litres.
US gallon 3.785 litres x 6 = 22.71 litres.
This accounts for some wildly different mileage figures, best to say 'miles per US gallon' etc.
As I wander off topic I thought I would share todays UK Unleaded Fuel price, now at $6 per US gallon.
E5 (5% ethanol) Unleaded Petrol £1.20 per litre.
£1.00 = $1.32
$1.32 x 3.785 = $4.996
Which oddly is about what we pay per UK gall in Pounds.

Thank you, truly great to follow this thread.

Thanks for the advice, unfortunately it did not help.
Finally got it working.
I deleted all Guzzidiag files then reloaded the Guzzidiag v47 zip file and extracted it. On starting Guzzidiag I was presented with a small pop-up window requesting language to be set, then another requesting v11 model and the Comm port!
Somehow I must have missed that on my original (last month) reinstallation. It seems you cannot change language or port again once fully installed.
EDIT I now see at the top of the screen 'File' which lets down an option for 'settings' where I can now select the Comm port. For some reason that was not visible before. So yes you can alter settings.

Shame most later Guzzi engines seem tilted back in the frame, tilted foward engines always look better, compare a Triumph T150 with a T160. I suppose it is to do with getting the shaft drive to have a reasonably stright run to make life easier for the universal joints. Later bikes have deeper sumps needing the motor to be mounted higher so making things worse.
No doubt some clever designer can sort that, even if it just visual by redesigning the heads and valve covers like the later BMW twins to give the illusion of a more aggresive looking engine.

Winter is here so I have started to play with Guzzidiag again, just downloaded v47 onto my XP MSI Wind netbook. When all connected up I can get GuzziRead to download the ECU after setting up the com port. However I cannot get Guzzidiag to connect. My problem is I cannot find the screen to setup my com port for Guzzidiag. I tried clicking on and around the top LH corner on the "v47", it just gives me the Windows minimise, quit options etc.
When I left click on the white cross on the v twin engine logo I get a row of options along the bottom of the screen, "connect" etc but nowhere to setup the com port. Right click sends me to the Guzzi De forum!
It has to be something stupid I am doing, please help.
As an aside, I have used these MSI Wind Netbooks, (models U90, U100 and U135), in the past to connect to Guzzidiag with great success, they are now rather old but are cheap second hand and come with Windows XP. Being only a 10 inch display they are small and portable enough to use in the garage. If fitted with a small SSD rather than a hard drive they can be used on the bike for datalogging.

Not so sure about the red frame around the seat and next to the headlight, nothing some black paint could'nt cure.

Lovely photos, where I live I am lucky if I can walk for 30 minutes before meeting someone, and that includes the New Forest!

Holy flywheels Batman.

I had my 850T3 flywheel lightened by turning a 1/4 inch off the outside, not forgetting to remark the timing positions, and fitted 950cc barrels. Kept the original carbs. After all the time it took to do the work I can honestly say I did not remember any huge change, felt much like it was before the work!

I can see all the Tonti boys locking their swinging arms away in a very safe place.

Possibly the end of the thackery spring/washer had worn to a sharp edge and was catching on the arm or the support, then it wound up a little before releasing. Might be worth rounding the ends of the washer.
It used to be a common mod to remove these thackery washers and shim out the gap to reduce friction, it was a little noisier of course but not important when racing. Ideally you only want a few thou clearance when hot, first of all set the gap to around 0.010" then get the motor hot, quickly check the hot gap then add/remove shims to set the gap to a few thou.

Is that the thing that goes up and down in a slow rythmical fashion?

I prefer 6.4mm, too scared to cut a length off her washing line.

You could try temporarily replacing the valve springs with very light springs, then slowly turn the engine over little by little checking the valve can still be pushed down and so are not contacting the pistons.
No need to remove the cylinder head. Use the old trick of filling the cylinder with string (leaving a tail out of the plug hole) then winding the piston up so the string compresses against the valve head. Now lever the valve spring cap down and remove the collets, cap and spring. Fit the light spring, cap collets etc. Remove the string and check as described above. Anyone who has done much work on aircraft piston engines will know this one.Edit: Should of added remove rocker arms for access to collets etc, and make sure you are on compression stroke.

There is one. Perhaps that works for you.
I bought that one, had to send it back as it had the common failed mileometer. Gear wheel worn, the needle indicated so the speedo part probably works. He refunded me OK, although I lost out on the return postage. He may relist it as u/s, may be of some use to add a mph dial to a kph item.

Amazing.

Hi, what size gauge did you opt for please.

After you click on New Content look at the left side of the screen, make sure you have clicked on the right display option, suggest you use 'New since my last visit'.

Found this on the UK Automobile Association website, dated 21 May 2017.
https://www.theaa.com/driving-advice/fuels-environment/biofuels
Basically UK uses 'Up to 5%' ethanol (E5), being phased in is E10 with 10%.
Interestingly ethanol fuel has less energy per volume so fuel consumption may be worse!

Pretty much the same in the UK. The local Ironmongers/Hardware shop don't sell anything really useful now, just decorating stuff and cheap basic tools. No more selection of nuts and bolts, metal stock or even proper paint stripper. The trouble is nobody mends anything any more.
