Hello does anyone know if there is a known problem with V11 sport cams, mine is a -01.

Mine is dead. but I am thinking if I should replace it with a breva cam instead.

Motoguzzi italia does not have the v11 cam anymore. But I found one at corsaitaliana. The breva cam is 3 times the price. Don´t know what to do.

And my guzzi has been in pieces since june. :homer:

My local dealer does not know.

HMB has also a range of uprated cams for Guzzis.

If you buy one of these, do not use the Kit with springs and valve spring retainers, as the V11 has good parts built in in the factory.

Use 8206 for more torque ore 7906 for more power.

I can't help you, but I know a man who can: Pietro diMarino on (0044) (0)1798 813260 - he's commonly known in these parts as Mr. Moto Guzzi!

try http://www.hmb-guzzi.de/ and let it "nitride" harden before mounting. they have lots of v11 stock.

thanks, now I got some options hmb might have hardend ones for sale. I`ll check with them.

Or is it a easy project to let someone do it. Don´t know what the result will be.

The cam on my 04 Coppa Italia frailed at 800 miles and I had to have it reground, reprofiled and hardened( together with lifter(s) by a specialist shop as MGNA had no spare cams in stock( probably woud still be waiting had I not taken matters in my own hands)... 2000 k miles later and all is well...surely there must be camshaft specialists in your parts...good luck and hope you'll be back on the road soon...

I think I may have had a cam failure, the symtoms were a increasing knock in the upper engine block, a loss of power getting worse over about 20 miles until the bike no longer wanted to climb hills.

 

I have stripped the cylinder heads and there is no problem with the top end so my next project is the cam?

 

The pushrods are perfect with no wear or marks visable.

 

Am I on the right track? :luigi:

John,to save time an easy check would be to measure cam lift with a dial gauge.That'll tell you right away.

I'd assume that the tappet clearance had opened right up? If not wrong tree :huh2:

To be more precise: measure and compare valve lift on all four of them. Remove the alternator cover and the plugs to turn the engine.

 

Anyway, my old LM3 has definitely a bad camshaft or worn lifters or something like that, but the lift is still okay. It seems that also minor damages make a lot of noise in the engine. Mine really sounds as if I have forgotten a tool under the valve covers.

Any news John?

 

Yup and its not good. The profiles on the camshaft are damaged, I'm not qualified to give a correct diagnosis but will have a competent mechanic give his opinion tomorrow.

 

I FOUND A NEW GUZZI TOOL !!!!!!! :grin: The 32mm nut on the crankshaft sprocket is a bitch to remove due to it being recessed in the sprocket and being less than half the width of a normal nut. A 32mm ring spanner will just slip off the nut as it has little or no grip, the answer is a 32mm plumbers sink socket (like a cheap spark plug socket with a hole in the center of the body for the screwdriver shaft). 10 Euro from your local plumbing supplier.

Not in the U.S. it's not! ;)

 

Thanks for the tip, tho': maybe it's available via McMaster-Carr?
