Pete, I think I mentioned to you before that pistons are made with the clearance already accounted for, so that if the size of the piston is 69.1 then the bore is taken out to that size. Based on Phil Irving expertise which is still good now, then the average clearance for pistons is about 0.005/inc...

They say, fools are easily parted from their money.

Take them to a platers that do zinc plating. They chemically strip what is left of the cosmetic chrome put on by Morini and replate in zinc to your bright/coloured requirements. Zinc is sacrificial so although it goes to a dullish grey over time rust does not appear. I have a 500 with zinc plated di...

I have one if you would like to call over tomorrow.

The 71mm Gilardoni and K2 barrels are sleeved too.

My 500's generally tick over at 1250 when warm and 350's used to tick over at 1350. You really need to make sure that cables are lubricated and free especially when turning handle bars. Also do as Evguru does and remove balance pipe and blank off, you cannot synchronize if carbs are connected, adjus...

Are the throttles balanced with vacuum gauges? Are the idle mixture holes clear and idle mixture set properly?

For those members who were dreams in their fathers ball bags or still in infant school in April 1981. the 250 cost £1345
Strada £1595, Sport £1695 and the 500 £1895.

As there is no 'seal' as such between the mechanical bit and electrical bit the oil drains into the electrical bit. The oil then combines with the carbon brushes to produce a thick black sludge which seizes the armature. That is the worse case scenario that I have found on customer bikes. Mostly the...

Not quite sure what EVGURU is talking about. Surely if you have no flat spots in your carburetion, means that it is sorted so perhaps everyone should fit 2-1 exhaust systems? I have removed the cross over pipe in the exhaust, which does make tuning easier. Having run Morinis both with 2-2 and 2-1 ex...

PS: The 26 mm PHBH carbs fit with no modifications. The 350 racer had 28mm PHBH carbs. PHBH are a much better carb with the round slides.

I run K & N's round filters and have never had any problems except rain at first dripping off the tank which drains into the float bowl. Solved that problem by inserting drain holes at the bottom side of the filter just before the 'bell mouth' and even in torrential rain no problems with water i...

How? Chemical composition of air is regarded as uniform unless you live in Bophal. Air density changes with pressure and for 'ordinary' bikes like Morinis it will not make a lot of difference unless like you, change your jets having taken pressure readings on a daily basis. In the dim and distant pa...

Contact Eurocarb (Contact Developments) 0118 943 1180 they are the Dellorto concessionaires and will advise you on options regarding your emulsion tube. I do not have a lot of faith in NLM when they told me that the air in England is different to the air in Italy! They will also send you if you ask ...

I have a tank if you are in need of one. It is a 350 with the bolt location at the front. Send me a personal message if you want it to discuss shipping etc.
