Conor Posted March 17, 2007 Report Posted March 17, 2007 Been to Boggs today to get the Capri set up on the rolling road. Was having a look around and nearly every car in there now has bike carbs on. The thing that was most impressive was a Rover V8 with a bank of 8 in the middle where a Holley 4 barrel previously sat. Old man Dave brought out a 1360 Mini that had two bike carbs fitted. The noise it made and the throttle response it had convinced me on the spot. Chatting about it, they're a bit up on performance on 45's, have far better throttle response and are a hell of a lot cheaper. Also it looks like they're more "everyday user friendly" as well. As for prices.. If you supply your own carbs, they'll refurb them, jet them to a base line setting and supply manifold etc for about £240. Another £100 on top if you don't have your own carbs. Full turnkey solution for a Pinto was £600 inc the dreaded VAT. If you're going to fit them on a Pinto though, you'll need a fuel pressure regulator as they run at a very low pressure - 2 PSI - which is way below what the mechanical fuel pump is set to.
MK II Mark Posted March 17, 2007 Report Posted March 17, 2007 Where can you get a fuel regulator from?
ExotronGammaPlusSequencer Posted March 17, 2007 Report Posted March 17, 2007 As i said above if you use the electric pump from an R1 or similar you dont need a regulator-this was the advice from Steve at Bogg Bros & about 100 people on the locost forum,my car has been using this setup for a year now
hotrs2000 Posted April 11, 2007 Report Posted April 11, 2007 I'm well happy with my R1 carbs, mine was the one in CF when they did the "how to fit bike carbs" a few months back.
emu Posted April 12, 2007 Report Posted April 12, 2007 If you need any info on them do a search on www.locostbuilders.co.uk theyve been bolting bike carbs onto stuff for ages So, I did as the man suggested. Now im really confused........Seems to be a fair few people bolting carbs from smaller bikes (GSX and FZR 600's)onto 2litre pintos? I was under the impresion that they neeed to be as big as possible!?!? The people who have done it though do seem more than happy with the end result, reporting good drivability and torque characteristics. I JUST DONT UNDERSTAND
Fiesta Steve Posted April 12, 2007 Report Posted April 12, 2007 reporting good drivability and torque characteristics. I JUST DONT UNDERSTAND In other words 'No horse-power' I bet that will upset a few people
alladdin Posted April 12, 2007 Report Posted April 12, 2007 webers need setting up far more frequently to get the most out of them... Do they Yes... otherwise you wouldn't need service kits for webers... Bike carbs are a far better design... i dont agree here sorry. sevice kits are for webbers that have wear / leaks / faults. normaly as a lot are possibly 30+ yrs old. they can go out of balance as can bike carbs. one point to remember. take a set of "base jetted" webers to your local rr and the guy can jet them to SUIT THE ENGINE. take a set of "base jetted" mikunis and chances are you are out of luck. for me the cost of old/worn webers is the main reason to go bike so i would want them for less than 600 notes. and im not anti bike bits... do prefer t/b's tho.... just my view
emu Posted April 12, 2007 Report Posted April 12, 2007 reporting good drivability and torque characteristics. I JUST DONT UNDERSTAND In other words 'No horse-power' I bet that will upset a few people One of the thoughts seemed to be that your better off with individual carbs, each with a 32mm bore, each feeding one cylinder rather than one with 32/36 (not unlike my DGV in fact ) feeding all four

So if I was to find bike carbs from a smaller bike with bores that were bigger than around 30mm then I might get somewhere!? (I did say I didnt understand ) I know im never gonna be making amazing power but a little more would be nice. And I want noise!!!!!

I had this discussion the other day with one of my mates and he said that bike carbs have been constantly developed right up until most of them went down the injection road around 2000 where as Webers are the same design from day one. I am not knocking Webers but I feel that bike carbs are bang upto date where as Webers aren't.
ExotronGammaPlusSequencer Posted April 13, 2007 Report Posted April 13, 2007 Old School Geezer must be the exception to the rule then as he bolted his just straight on and they worked without re-jetting. Just to clear up any misunderstanding mine have been rejetted but not set up yet,When i got them from Bogg bros they came refurbished & base jetted(i have said this in most of the other posts) the same way webers would be as alladdin pointed out.. Im sure most people realise you cant just unbolt a set from a bike & strap them on the side of your pinto,the same way you cant get a pair of webers off an old alfa & expect them to run perfectly reporting good drivability and torque characteristics. In other words 'No horse-power' :mrgreen I bet that will upset a few people Is this supposed to mean we all brag about driveability because weve not gained any power ? Ive only commented on the driveability because it is a FACT the car drives better than any of the cars ive had with webers/dellortos Most of the other people on locostbuilders have said the same thing-we cant all be wrong? Or do you mean none of us have big power engines? Its not our fault if we build our cars to suit our requirements & not just for ultimate bhp. Im not trying to convert anyone & dont really care what people use,ive just tried to answer peoples questions based on my own experience with bike carbs.
badchild Posted April 13, 2007 Report Posted April 13, 2007 Just a thought but would they have to be 1000cc carbs? i mean would gsx600 or gsx800 etc etc carbs do 4 a 1600 xflow?

Im not trying to convert anyone & dont really care what people use,ive just tried to answer peoples questions based on my own experience with bike carbs. Ive commented on drivability because thats whats important to me. As much as I would like a 200pony pinto it wouldnt be ideal for sitting in nose-to-tail traffic I endure to work every day. But I still want a car I can have some fun with and play around with. The reasons for my post were based on there seeming to be quite a few people on Locostbuilders who are using 600cc bike carbs on Pinto's. This seems to go against general opinion of using those from larger bikes. However, smaller carbs seem to be a lot cheaper and as with sidedrafts I would imagine that a carb that is too large is just an overkill if the rest of the engine isnt built to use them. My pinto is standard except for a fast road cam. so I would therefore assume that rather than using big carbs I could use littl'uns (which would still be better than 1 DGV)????
ExotronGammaPlusSequencer Posted April 13, 2007 Report Posted April 13, 2007 I wasnt quoting you emu ,i meant steves no horsepower comment. When i was researching using them i was advised to go for R1 carbs which are 40mm yet whenever the subject comes up on here i am told they are too small? To be honest ive not really looked into the subject much since i fitted mine but i thought because of the design larger carbs being "overkill" isnt an issue.Most people said mine are fine,a few have said they are too small,yet everyone else whos fitted them loves them If you are intent on using smaller carbs maybe the best people to ask are the people on locostbuilders who are using them? The conversions ive seen on 2.0 pintos have used the same as mine. Ive posted my reasons for using them countless times elsewhere & dont need to go over it again-they are still on the car after a year which i think confirms they are as good as i was led to believe theyd be
emu Posted April 13, 2007 Report Posted April 13, 2007 I wasnt quoting you emu I must have a guilty conscience then . I think ill send a few PM's over on Locostbuilders. See what sort of response I get.I can see why people would say that they would be too small but to my mind if thats the case then the DGV must be terrible . I guess a lot of it comes down to how the airflow distributes to each cylinder.
Arched Escy Posted April 13, 2007 Report Posted April 13, 2007 Mine have been taken off as they are misfiring like fook.
X-pack-Glyn Posted April 13, 2007 Report Posted April 13, 2007 whats going on with all this bike carbs lark anyway.... webber didnt give us DCOE,s for nothing you know!
emu Posted April 13, 2007 Report Posted April 13, 2007 Maybe not, but they also didnt exactly make them cheap either.
X-pack-Glyn Posted April 13, 2007 Report Posted April 13, 2007 the best of anything is never cheap you dont get owt for nowt in this world.
emu Posted April 13, 2007 Report Posted April 13, 2007 the best of anything is never cheap you dont get owt for nowt in this world. Im happy to keep trying though, at least until someone leaves a set of 45's on my doorstep
