bike carbs off a cbr600 is what i used, another member had 2 weber 36dcnf's on theres, some other members hava had weber 34ICH carbs on, any weber that is suited to a similar size of engine could be made to work properly, but will have to be set up properly.
almost anything you do is going to need modification to the inlet manifold, weather it be an adapter plate being made, or in some cases a custom manifold,
i have a pair af weber 36dcnf's id part with for the right money, but im not bothered if i have to keep them.

You won't get a huge ammount of extra power out of just changing the carb. It would be best to fit performace manifolds (both inlet and exhaust) in addition because the stocks tend to strangle the engine. I polished the internal surfaces of my stock manifolds and it definately helps, it didn't give it any extra power im sure but it sharpened the reponse a little and reduced the growling considerably. You should consider converting back from electronic carb to the origional type and manifolds, that way you will have more control over your mixture and such instead of making do with computer dictated values.
I think the easiest thing to do to start with is just simply lighten up your car, less weight is always better. (Y)

Cheers guys, thats what iv'e gathered, but just wanted sumone to actually say 4 shure lol. About the manifolds, what would be a good choice for the out - Ive seen somone with a k11 on and others on ebay etc. And would I it be best to get one made, or what cos again ive read about ppl having to do that - and I cant realy do that myself so would rater buy one if possible.

Well if you do change your exhaust manifold and you don't want your old one, if it's the cat type with the EGR pipe on it then let me know coz i'm after one of these.

twin 40's far too big for a 1.2, actually far too big for a 1.6, twin 36's are about your limit on the 1.2, i did the calculations when i bought my webers and came out at 36's.
900 fireblade carbs might work, this is an unknown as i cant think of anyone trying them, everyone seems to go with 600's (well all the about 3 or 4 that have ACTUALLY done it)
750 carbs seem nearer the mark, im not up on bike carbs but the hohda cbr600 ones i had were variable venturie carbs with sliding needle jets, i was led to believe that they were the best to go for, not sure if gs750 carbs are that or not.
again 900 carbs are unknown, id hazard a guess at them being too big for the engine, my 600 carbs and other peoples ran on the lean side, if i were to do it again id be temter to go to 650 or 700 carbs or evern 750, but definately not 900.
the last one, i cant see personally how they can be advertised as 750 and 1100 carbs but like i say im no expert, but either way see above, and 1100 is way too big for the 1.2 you have
"Or none?? And Superls whats the deal with you puttin 600cc carbs on- u told me to find a similar CC webber n and u got half ?"
im not going to say non, cos theres a chance that you could get all of your links to work with your engine, some easier than others.
yes when i said about webers the rule should be stuck to, cos webers are designed to run on car engined, 7k redline and all that etc, so you need one off a similar size engine, there are so many things to change in a carb, its not just the main jets if it boggs down, theres tonnes of stuff, im not going to get into it now, but read anywhere about webers and it will become apparent. and i put 600 carbs on my 1.2 for this reason, im not going to lie to you, i did it cos a well renowned company who do bike carb conversions for every car on the planet, who do this stuff day in and day out used them on a micra 1.2, the company is bogg brothers.
so i thought if the major player in carb conversions is using these carbs i will too. simple as that, but i read up and learned why, cos thats how i am, basically on a honda cbr600 your producing in trhe region of 100bhp (approx i dont know exactly and cba to check) so you know the cbr600 carbs are well capable of that, a maxed out ma12 with the works on it will make around 100bhp, so forget cc's think bhp's.
where as a 1000 fireblade will make the thick end of 200bhp, so no matter what you do to your ma12 it will still only make 100bhp so why put 200bhp carbs on a 100bhp engine???
another comparison could be made like so, you have a micra 1.3 turbo making 200bhp, why would you get a turbo capable of 700bhp and fit it? you wouldnt...
before anybody pipes up, im sure ive got some figures off, but there near enough, and i know charging an ma12 will be more than 100bhp, but thats a differnet story.

I'd like to see someone use an ma12 in an st setup, that would be fun... or dangerous.
OP

Cheers. I thnk ill go for the cbr 600 then, and ive been hunting for carb tuners or specialists for reccomendations n parts, and I cant find ANY. Everyone I ask says 'no one does carbs anymore' Ill check up on bogg brothers sound good. The next step is the mani, u made ur own didtn you Superls, would you do one for me for the rite money? Id love to try myself, (probly flop but would be fun) but i got nothing even like a workshop/garage (I read ur tuning blog). Also, what should i do about the outlet, u made ur own again no?
Oh yeh, how much should i pay for the carb £75 buynow looks a bit high ?

unfortunately i cant make k10 stuff anymore as i dont have an engine to model things on, its easy enough to do if you have the right tools, again same with outlet,
and yes £75 is way too high, my first set cost me 99p with £14 postage, i have a set here i bought for my cg engined k10, they cost me £25, you can have them for that.

Well if no-one does carbs and since you're thinking about custom manifolds anyway, why not convert to fuel injection? I'm sure with some adjustments that k11 parts could be used, which will cut the costs down since these parts are easily available.
OP
OP
Its a cbr600 carb yeh? If so - Ill take it!! And porkpie700, I think ill stick with the carb, I havent realy reaserched injection conversion either, and I recon its probably more complicated. This is kinda off topic but im doing the suspension too, ive herd k11 wishbnes go straight on and fit with k10 shocks, think they do...?
Cheers.
Cheers.

I'm not so sure about the wishbones, but the shocks are intrchangable, you can put k11 front shocks on the k10 but if you need new wish bones you can still get k10 ones, £30 each i paid 3 months ago plus 2 new track-rods for £17 and 2 new front wheel bearings for £12. Add all that up and it makes the front end a hell of a lot tighter, it did for me anyway.

K10 Tuner
yea there cbr600 carbs, pm me if you like, k11 wishbones will fit, but you either need the rear mounting bracket thingy off a k11 or you need to put the smaller diuameter k10 rear bush on the k11 wishbone, both easy to do, id put the k11 rear mount on personally and retain the beefier k11 bushings.
OP
OP
KL kl, the suspension is kinda worn... are all the cheap micra suspension parts on ebay ok? Also for the inlet im thinking of geting a micra mani, and a cbr mani, and mating them, u reccon it would b good? bog bros sed £170 + vat for one. what year n model ect is the carb - im looking for the gasket.
