Moto Guzzi V40 owner's manual?

Ahh great, thank you expensive moto guzzi

My understanding of the small blocks is the final drives are all the same and its the intermediate reduction in the gearbox that needs changing.

Probably not worth the expense of fitting bigger cylinders as you may need to change the cam too....

mark and rolly from scooterazzi deal with my V40 here in wellington and afew comments have slipped of boaring it out to be a 650. just a nice little boost for the open road, since it sucks ass as soon as it reaches 100kph. reeving at 5000 on 5th gear.
could this be a good idea?

can that be done with out replacment barrels etc? might give extra HP but as Paul says the gearing will still be the same.

You would need to do more research but as Dangerous says - you will be replacing parts not boring out the existing ones. Guzzi generally used plated bores which cant be over sized BUT the cylinders were relatively cheap anyway.

Most of the 400's were made for the Japanes market and were just bigger models with smaller pots. Guzzi always have periods where they are struggling to make money and they would have kept any 'special' parts for a 400 to the utter minimum.

Call Pete at Moto Kiwi as he is bound to know more...
