1.3 with bike carb?

hi guys,

seen many people talking about putting a bike carb or bike carb's onto a 1.3, I asked my friend and he said.. well its a 1.3…. but if I were to do this would I notice a big increase in power/throttle response or is it a waste of money?

thanks

Would expect it to be a waste of money

I'm kinda in the process of getting this done myself just need to get the manifold gasket sent off for the guy to make up a flange and tube kit. The carbs I am using are GSXR 600 SRAD and only because of those sexy red trumpets which will match the paintwork.
Not sure if it will be a massive improvement but it definately will be one, I mean think about it you would have four carbs instead of one and better carbs at that, plus the sound of them!! The carbs will need setting up properly though this could be done by yourself if you are capable and have the tools, the knowlege is out there!

Don't listen to the haters! This set up will end up costing me around £100 and ok I might not be getting 200bhp, but for the time being that's fine, I am doing it for the fun of it and hope to gain slightly better performance.

Will only be good if you have them set up properly on a roller.
Doubt you'll see massive gains apart from the sound of them, they sound awesome.

The response on them is good though but can be a pain.

If your gunna do it, cheapest way is by yourself, DIY. If your handy it won't cost you that much and woul be fun to do if your gunna pay for it then id say a waste of money tbh.

I'm not a hater of carbs I have a set myself.

Its got nothing to do with being a hater, forcing more fuel into an engine will not make it go faster, theres a bit more to it than that, as for the sound just remove the standard air filter system.

hi, peeps, as for performance, from bike carbs,yes it does work,iv done this to my daughters 1.3 running four branch, and five speed box. on r6 bike carbs. im all so building an abf on zzr1100 bike .CARBS.

For sure what goes in must come out, which is why people fit big shiney four branch manifolds, however if you think about it, if you have a single carb sat in the middle of the inlet manifold, the centre two cylinders tend to get more fuel so by fitting four carbs it will balance the fuel delivery equally. Providing they are set up properly the engine will run smoother and breathe a bit more easily.

So you think 4 individual throttles is no different to 1 small throttle shared by four cylinders? You're not forcing more fuel in with bike carbs, you're allowing better, more direct airflow with a more efficient source of fuel.  That = more power and better throttle response.  If you think that bike carbs are un-economical then you are either an idiot or you haven't had the carbs set up properly.  And it CERTAINLY doesn't sound the same as a solex with the filter removed    

Whether it's worth doing to a 1.3, it depends on how attached you are to having a small block mk1.  If you are adament you want to keep it but gain a bit more power then yes it is worth it.  You won't be beating everyone else off the traffic lights with it, but you will have a much more lively, fun small block mk1  You can't expect it to always be simple to do though, they were designed to be used with an engine very different to the mk1s, so it needs patience to work well and no bodgery. :wink:

Where did i say bike carbe are uneconomical? in my first post i said "expect "  a waste of time, why the need to call others an idiot? for voicing my opinion

I didn't mean to sound like I was calling you personally an idiot, I meant whoever believes that particular wrong information because they haven't made the effort to do it properly.  I've seen numerous people say that they're not economical, and from my own experience they are a hell of a lot more economical than the original solex thanks to a rolling road set up by Bogg Bros!


Don't get me wrong, they have their faults, and I have since discovered the wonders of electronic fuel injection, but bike carbs really are the next best thing.  If they weren't, bike manufacturers wouldn't have continued using them for decades after car manufacturers moved onto EFI.


Far from a waste of time.
