Lets see your bike carbs!

I could show you mine, but they're all attached to my bikes, so wouldn't be that interesting

Sorry mate, i don't have any more pics of the tu one.. If you are bike carbing yours my suggestion is that you get rid of youre head, and fit a 106 rallye head and cam, then bike carbs on that.. You then have a much better head and cam, then you can put your distributor housing into the rallye head. This is what i did on my 205 rallye but with 40s.. Its a simple bolt on affair. You will have to block the injector ports on the head but this can be done using just a fuel rail and injectors or just make up some little blanks.. This combo on the 1400 makes a lovely little engine. I will be going back home to devon on the bank holiday weekend and think i have a head and cam still somewhere so i will try and dig it out for you!

cheers

Any better pictures of this? How much gain were you expecting over the M40 with standard injection?

Cheers

[stoopid question]
whats the differences fitting-wise and what are the advantages of doing this over fitting normal carbs like twin 40`s etc?
[/stoopid question]

Just like slater said!

When you think about it, webers etc are based on a 50s, compromised design, Bike carbs are designed by geniuses with computers,haha when setup correctly will be far supperior at providing the right amount of fuel accross the rev range.. And they are cheeeeeeep ;D

Is this true though? No-one's ever cleared this up for me. The way i see carbs vs. injection is that carbs have one 'setting' (for want of a better word) of how much fuel will be delivered, decided by timing, mixture and jet settings, which is why on some highly strung carb engines you get too much fuel low end revs as a compromise for the right fuelling at the top end with your peak power.

Then if i understand it right injection plus ECU and correct map the amount of fuel, timing etc are all adjusted constantly over the rev range to give the optimum settings at that particular RPM.

I always assumed bike carbs were much the same as 'normal' carbs in that they had one 'setting'? Maby my understanding is wrong, could anyone clear this up? I'm maby veering away from the original topic of just pics and can start a new topic if anyone wants

Also, bike carbs seem a little hyped up because won't linkages etc bend after a while, since their components are only used to the movement of a hand twisting rather than a heavy foot pushing a throttle pedal?

Edcobb - Did you space your carbs out and make different linkages etc or, as it's only occured to me now, did you keep all that standard and used the silicon hose to get it to line up with the manifold?

Thats all my questions for the time being

Apologies, phrased it wrongly. If a weber has the one 'setting' (get me a better word) how can bike carbs be any different?

I think a lot of bike carbs are varible venturi, like an SU.
Webers have fixed venturis which means they have a sweet spot in the rev range where they work best and everything else is a compromise.

Sorry but that make me laugh!

The force required to open the butterflys is still the same so theres no diferance relly. Force on the stop would be greater but i don't think it would be much

Bike carbs are totaly differant to webbers in their design. Carbs don't have 'one setting' either they give to a cirtan amount of fuel for a cirtan pressure drop across the carb, then they piggy back on some odds and ends to compensate for the other stuff like tempreture (choke, bi-metalic strips etc.), throttle opening speed etc. (accel pump). The Bike carb just does it better!
