Fitting Mikuni carbs

[Vince Farrell]

I dont think based on the information above I would risk spending money on mikuni. (you got to admit its a bit sketchy) what sort of mikuni for a start VM ?TM? suduco? RS? The US site looks a better bet at least there is a carb selected to suit and all the jets and slides sorted is there anywhere like that in UK?

Vincent owners are hard ‘Task Masters’. Trying to answer questions isn’t
good enough, apparently answering the ones not yet asked is also
a requirement.

Lets ask Brian Chapman what he thinks of the Mikuni`s he has fitted on his solo.

dont wish to spoil the flow, but I fitted dell'ortos from don godden as was; Perfect. They said use 34mm, angle to fit, I did, started first kick, has done ever since.

Well, Ducati tuners used to put 40mm carbs on 250cc race bikes.

What model number dell'ortos did you fit?

 

[vibrac]

Dell-ortos are still in production although they stoped making car carbs when the damm injectors and computers were forced on us when cars got too reliable and garages were running out of work . The delorto.com & co.uk are both owned by eurocarb (webber) I suppose the factory web page is a bit harder to find This does sound like a better option I too would like to know the model....

I have recently Dellorto's PHBH 30 MM fitted which i did have for about 10 years on stock, came off a tuned B Black shadow with 9:1 pistons. Fitting the front carburettor was a bit tricky because at first the carb touched the rear cilinderhead and after altering the inlet manifold the bottom welding seam of the petrol tank came just in line with the choke connection, removed 5 MM from the inlet stub.
In the flanges of the manifolds i did make M5 connections for vacuum metering and the carbs can be nicely adjusted. The bike is easy to start and performs after 2100 revs very good.

Has anyone put the Dellorto PHF 36mm on a Vincent. If so, are there any modifications necessary? Thanks, Dan

Hello Dan, I have had PHF36AD carbs on my Special road bike since mid 70s, I went that way because I raced it in street class, As well as on the road. Just a road bike now.They are good carbs, But a bit big. My Brother made long alloy manifolds, there is not much room under the tank, And I use two front Cyl' Heads. Unless you are going to go for Top speed, I would put a smaller carb on, You will get a better tickover with a small one. Up till 1980 I ran 12 to one pistons on 100 type petrol, Now the petrol is not so good i only use 9 to one, I took the pump arms out of the carbs because it made them too rich. Good luck Bill.
