2006 breva head compatible with v11 ?

[motoguzzimick]

Anyone on here ever fitted a set of 2006 1100 breva twin plug heads to a 1100 guzzi

I wondered about that as well, I remember folk did it with old Tonti models.

 

I was told one problem is if a plug or one coil fails the cylinder is then running retarded with possible overheating and piston and exhaust header damage. You don't know the plug has failed, as the drop in performance will not be great, until you see the header glowing cherry red.

 

 

I found this earlier thread by Motoguzznix.

ive had a couple of engines twin plugged in the past .it makes a diffrence, im always tinkering so if the plugs fail,.......

the throttle response is improved and the engine runs leaner ,also need  to be able to retard the ignition advance 4 deg and so on 

i have a power commander on mine so i can do that

raceco used to have the info on is website 

the base gaskets look the same but the head gaskets have diffrent part numbers

bit nervous about spending too much money......ummm

I bow to personal experience, also got myself well confused with Motoguzznix and Motoguzzimick!

 

Glad to hear plug failure not a problem, it would be an easy mod on my old T3.

Ohh thank you for the link ..... Super duper interesting read

On the breva heads the oil ways are already moved too ......

I thought as much ,the should drop straight on... Compression ratio is diffrent,depending what you read

 

Nice easy project then

All you need now is cash.

 

Have you tried Nik's Euro Bits on 07980639289, also on Ebay as nik-w. Based near Chichester.

He has a wealth of Guzzi knowledge and specialises in Guzzi bits, you may have met him at Autojumbles.

To be honest nige at NBS is the man for this .....

I did a 992 motor I bought from Steve Wesson back in the day

I went down 10 points on the main jets on 40mm pumpers ,pumps detached so 150 to 140 mains 60 to 55 pilot jet

13 deg advance at idle to 28 degrees from 32 at full advance I think I set that at 5500 rpm (I just couldn't Rev it any harder)

I'm almost 100 percent that it can be done and that those kind of figures will work

 

It worked well ,the bike was a responsive as my v11,but it took along time to get it right .... And a few diffrent strobe lamps too.....

But now I have a power commander ........and a laptop ,I've never tried it but it got to be easy enough

Interesting to see that the factory does it as standard now

If I go through with it I'll post some pictures and so on

Any how thanks for the links ... Very interesting
