1034cc SF Engine build (Slowly)

[bob]

Julian, If you want high efficiency with a vintage aesthetic then I reckon you should have a look at a pair of Gardener carbs. De rigueur for hot Manxs and G50s.

As ex radio officer i am used to all cineds of "strange" sounds wich make sense in my ears. Like the sound of cam sprocket drive by Honda rc 30 , 10 years i have Honda NS400R with Joly Moto exhost , FCR idle sound on ZXr750R  this is music for my ears etc. .

And I, as an engineer, are very suspect of anything mechanical that's noisy!  Imho, mechanicals should operate smoothly and silently, old stationary petrol or steam engines are a fine example, all that is audible is the puff-puff of the exhaust.....

So it should be with a motorcycle engine, a smooth and harmonic togetherness of individual components.  No rattling, no clanging around, a faint ticking of tappets and whirring of chains is about all that's acceptable, and if the exhaust note is subdued (fat chance within the Lav scene...), fantastic! 8)

As soon as mechanicals start rattling/knocking/rumbling, they're either fucked or badly designed!

Piet and what is with "Zen and art of motorcicle maintenance " bad design is more than inaf on motorcicles . You are right and i was joking ,but i realy like sound of Jolly Motos above 10000rpm , FCR at idle you have feeling ther is something falling apart in engine , and so on .

Thanks for the correction Marnix Now perhaps I can help you with a small error in your grammar. When using an ellipsis one should always use three dots and they should be preceded and succeeded by a space ... actually

 

[MarnixSFC]

It's Gardner actually ...  :-* 

 

[bob]

That's better Marnix, these little details are important. And not at all pedantic ...

 

[Davo]

Ellipsis which touch wine ...

 

[henry]

That's better Marnix, these little details are important. And not at all pedantic ...

since when do you start a (unfinished) sentence with And???

 

[Grant]

Or with lower case?

 

[Cosi]

Fuck

I wish Julian would get back from skiing  :

 

[Kiwi Laverda]

Sound like Julian is being rather unreasonable, going off skiing with an interesting project on the go and leaving the commenting to the wandering minds.
Get off the ski's and get back to the project  we are all waiting for the outcome and to see and hear it on YouTube..........

Henry, starting a sentence with 'and' is becoming more widespread and is now accepted in informal writing styles  , particularly for comedic effect. And that is how it was used on this occasion...

 

[bob]

[henry]

Or with lower case?

i confess to indifferent idleness regarding the use of lower case only, but you can't accuse me of poor syntax!

if my students start a sentence with 'and' they get a big red splodge for it! and is a linking word for joining compatable/additional ideas together in a single sentence. it is NOT (see, i do know how upper case works) for starting a sentence despite any form of acceptance by any bunch of semi-literate morons, especially in the media, who claim it is okay, even if only for informal use. we should not pay them any attention! like spraying andy's toenails red (i believe tim is going to do them either blue or green) it is wrong!

for comedic or any other stressed effect i suggest the use of space dash space. if you wish to subvert it to the main sentence, enclose it in brackets.

and is a linking word for joining compatable/additional ideas together in a single sentence.

So, does that sentence get a big red splodge....................??

 

[mcnicol]

Henry, I wasn't going to say anything, I'm a much worse offender than you, I can't type even when I'm sober, but it's "compatible", not "compatable".

Hi Guys!
Back from skiing and very much enlightened in the use of "and" and .....s etc 

Didn't break any legs so all ok to start work again 

Carbs!
Am listening very much to all your comments and finding them all very interesting!
I think maybe that I will do something fun!  As I will probably be building 2 engines I think I will buy a pair of each and test them back to back!  then decide which to use on which bike!  or maybe even which to save and use on something else entirely!  I have heard similar comments when comparing SUs to Webers etc on car engines but to date after relentless testing, other than finding "small" drivability differences and only "slightly" larger top end differences there is no massive gain for either if setup correctly and using units with similar air flow capabilities etc.
Will be very interesting to test. 
My max revs will be aimed at about the 7500-8000max mark so I don't think max airflow on carbs of about 40mm will be the issue here anyway!  Maybe I will test them on the flow bench though just for a fun comparison.

Looks are for me not the be all and end all but I do find that a nice period looking bike can be easily spoiled by too modern fittings etc.  For instance, I don't even like discs very much   so whatever I use in the end will have to fit this criteria! or be modified to look old which is also a possibility if needed.  None of my bikes will ever (while in my possession) be used for either serious racing or long distance touring so the last ounce of power will not be wrung from any work I do to them, nor will I really care if the carb (due to it's design) is not giving absolute max power, so long as the "roll on" of power is strong and consistent, smooth and without hesitations etc!  One thing that bothers me about the RCs is Lothar's comment about giving full throttle and having to feather it!  That in my book for my use would be un-tolerable. Is this a feature of CRs etc or just on occasion?

Interesting thoughts though and thanks to you all for making this build even more complicated 

Julian,
Glad to be back  :-\

if my students start a sentence with 'and' I encourage them to self flagelllate with a Sjambok! and is a linking word for joining compatable/additional ideas together in a single sentence.

Each to his own Henry but it seems a bit harsh to me. But what do I know? I'm one of the semi literate morons you refer to
