Norge 8v GT , oil pressure switch leak

Norge 8v GT ,

had a leaking oil pressure switch , to get to it involves seat, panels,and fuel tank …then you remove the lower fairing , on both sides to access the inlet manifolds to the throttle bodies .

then you can remove the airbox , underneath is the oil pressure switch. It also means you can get to everywhere to clean up the oil that has leaked out .

new switch has an adapter to fit new type of switch , so hopefully it won’t happen again .

clean everything up and screw it all back together.

Guzzi mechanics talking to each other via “FilterMail “

v7 pics 003

When there used to be lots of guzzi workshops in London , ….this is how we would send messages to each other .

I once took out a filter that was 25 years old , message written by a mechanic in 3 Cross . He still worked at a dealer nearby , took it to show him ….he nearly fell over !


1200 Sport


1200 Sport , one of my all-time favourite Guzzi’s , i don’t think there are 200 in the UK .

A  do everything bike , comparable to a VFR750 , doesn’t do anything fantastic , just does everything well.

Fast enough to get from A 2 B at a very good average speed , comfy if you mod the seat a bit  and put on the later bars , fuel efficient , 40+ mpg , good looking , forgiving chassis , good brakes , what more do you need?

Put on the factory 2 into 2 exhaust system , and lose a bit …ok a lot , of weight ,AND  get some noise out of it .


Yes Sir , we will service your new bike before you pick it up !

So , a new owner says… give it a service , so we have a start point. Shouldn’t need much he says , i’ve only done 5-600 miles since i got it . Dropped the oil out and took off the sump… oil filter dated 2012 , thick black sludge in the sump , a drain washer that has been used more than once is cut off of the drain bolt. Double gaskets on the rocker covers ? and valves so very tight , carb balance a mile off , and mixture screws set at 2 turns out not the 3 1/2 turns out the engine wants .

Run it down the road for an MOT , tester can’t get it out of gear , passes with flying colours .

Griso 1200 clutch plate . worn right down to the rivets . The centre of the plate was rubbing against the middle of the pressure plate , causing the clutch to slip under load . You can see the shiney part on the rivets where they are touching the pressure plate .


Does your drive box oil come out looking like this ?

25-2 009

does your oil come out like this ?

this is oil with maybe 10% water in it . Probably caused by lots of short journeys , where the drive box doesn’t get hot enough to make the water evaporate off .
solution , change you oil more frequently , open out the hole in the vent at the breather .

When you change it , try and do it hot , just after a ride is best , leave it to drain , overnight if you can .

Then refill to the correct level .

You may need to do this twice in quick succession , to get all the affected oil out.

Your drive box is an expensive bit of engineering , oil changes are very cheap by comparison .


what bike mags do you read ?

so what bike magazines /papers do you read ?


Oh dear !

rear output bearing has failed .

gearbox is so damaged it isn’t worth fixing .
