Umm i think we can safely say theres not a car currently in production on the planet (except maybe Skoda) that are still using carbies. Your mates are clearly from the V8 dinosaur set. Even most V8 guys realise fuel injection is the way to go nowadays.

As you may or may not be aware theres two types of fuel delivery systems, one primitive (carburettors) and one modern (fuel injection).

Kinda offtopic, but why do brand new motorbikes still use carbies? Surely it can't add much more to the price to chuck an ECU in there. I remember being amazed that my 94 CC Lancer used one, but then I found out that 2003 model Kawasaki 250cc bikes are using them!

ah ok, so then I suppose if they slide (which I take to mean they adjust themselves and aren't locked for efficiency at a single point), then they would be almost as efficient as EFI as they aren't just set to be optimal at a particular rev point. Am I totally off? I've got no knowledge of pre EFI tech at all really :D

I can't think of any current model sportsbike that hasn't swapped over to fuel injection. The Yamaha R6 and R1 were 2 of the last to change over.

The difference on bikes with carbs and injectors is not that great. You can get virtually as much power out of flatside carbs on a bike as fuel injection, you will just suffer a tiny bit of response and economy. Even though it is cheap to put an ECU and injectors in, carbs were still generally cheaper (until recently at least). The main reason why Yamaha finally made the move is because everyone else did it, and was therefore a marketing ploy rather than a performance one.

The biggest problem with carbs on bikes is tuning the buggers.

Edit: Many Jap "cruiser" type bikes still use carbs, but this is more to do with the "image" of trying to look like a Harley. Again, marketing.

Majority of new bikes use injection, any that don't is cos its more cost affective.

I was only out at the track a few weeks back and there was a 1600 running an SR20DE with twin sideys (personally i would have gone quad throttle bodys if anything).

and i am sure some of u guys have seen the S14 drag car running an L31(stroked L28) with twin turbos and triple webbers? that thing as mad!!

could someone verify for me if it was running methonol? and possibly nitrous?

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
