[Universal Joint replacement]

Hey everyone,

Does anyone have the exact size of the Universal joint ?

 

In the U-Joint Store they list to uni joints for Guzzi - http://theujointstore.com/moto-guzzi.html but not what bike they fit.

Measuring the OD of the bearing is 22mm on Uni i have out 

Measuring the distance across the bearing is 51.7mm

 

Can't seem to find much info on ebay or any of the main guzzi shop websites, but i am just after a replacement rather than an entire shaft and uni's.

 

regards Neil

Have a look at their B1 catalogue.http://www.hardyspicer.com.au/driveline_products.asp

 

Cheers

[guzzidiag maps.]

They have different degrees/voltage slopes .

Here's a fine write up http://archive.guzzitech.com/HD-TPS-Jeff_B.html

[How are fuel map corrections used in a ecu?]

According to Meinolf , who's done a test bench simulation with the 15M , right cylinder , start enrichment and acceleration enrichment are offsets to the base map .

Air/oil temp , air pressure and battery voltage trims modify the above sum by percentage .

[EV Map on my V11S?]

Seems like too much advance is removed .

Usually a couple or three degrees less does the trick .

[Custom pistons from Pistal ?]

Hi all,

 

I've been looking for a set of high compression pistons here in the EU for some time and emailed Agostini , Omega and Pistal Racing .

Here is what Pistal answered yesterday .

 

 

Hi Angelo,

I will make some investigation from a friend dealing with Moto Guzzi since years, I did some racing piston for him few years ago, is the Moto Guzzi dealer in Parma, if I will make some pistons for your engine you will be the first to know.

Kind regards

Dear Giorgio,
Thank you for your swift reply.
V11 was produced between 1998 and 2006 .
It is a two valve per cylinder engine of  92mm piston diameter ..
Although much loved by it's owners , some of them suffer from pre-ignition (knock,pinging) due to the mismatch of the stock piston top to the combustion chamber , leading to slow flame speed .
Even with high octane fuel , mine pinged near 4500-5000 rpm .
Adding more fuel or retarding the spark timing is not a desirable way to cure this phenomenon .
I believe that , if you would make a better shaped piston top , with a mild increase of compression ratio from the stock 9.3 : 1 , you would have a winner .
If you are interested ,  when I open the motor , I will try to send you a piston , a rubber mold of the combustion chamber and whatever measurements of interest I can take from it.
I will contact you first .

Best regards
Angelo

 

 

My take on the matter is , we can have a hand at determining the specs for the end product .

I , for one , would like long (as the OEM) skirts  and as much as possible extended squish band .

Others , more knowledgeable than me , might suggest some other desirable characteristics .

[U-joint life estimate]

Thanks for the feedback gents .

The old U-joints were regularly greased , I expect to find them in very good condition .

I did find some driveshaft firms in England and Germany .

[U-joint life estimate]

Hi all ,

 

I replaced the driveshaft on a friend's V11 at 30K kms as a precaution .

Is there someone who can estimate the remaining life of the old D/S and repair the U-joints ?

Preferably in Europe ?

IIRC there was someone in Germany who did this, but search as I might , I couldn't find him .

Any suggestions ?

 

Cheers
