capri_boy Posted March 16, 2007 Report Posted March 16, 2007 Hey i done a search but couldnt find an answer i was lookin for..... I was considering R1 carbs for my capri. Everyone ive asked before has said not to do it and fit webbers instead. what r the draw backs to fitting bike carbs? Does it really effect torque that much. Anyone had any probs with them? and is there anything i should know before i do it, any advice?? cheers folks
capri_boy Posted March 16, 2007 Author Report Posted March 16, 2007 Allready said my views I know mate, but there must be more to life than webbers!!!!!
GT_Jim Posted March 16, 2007 Report Posted March 16, 2007 a frind has some on his capri i thought the made a huge differnce to the 38dgas he had on his pinto, what spec is yours dude?
capri_boy Posted March 16, 2007 Author Report Posted March 16, 2007 a frind has some on his capri i thought the made a huge differnce to the 38dgas he had on his pinto, what spec is yours dude? im just running a standard 2.0l pinto, i have an Ashley 4 branch system and will eventually fit a cam. Thats about all i have planned. im running a 32/36 webber just now. I think i can do the conversion for about £400, where as webbers will cost that 2nd hand, and will probably be knackered.
GT_Jim Posted March 16, 2007 Report Posted March 16, 2007 thats why he did it, he has a 2l pinto with a mild road cam and a lightend flywheel and ahs ahd head work done, it pulls so well in 3rd it was in cf last year with the 3.0s capri
Arched Escy Posted March 16, 2007 Report Posted March 16, 2007 Have mine in the garage,putting them on the car on Monday,so I'll reserve judgement till then
Gareth Posted March 16, 2007 Report Posted March 16, 2007 I've read that they're similar to fittin 40's, but give a bit better throttle response. I plan to fit some one day. Plus I think it's different...... For now

Plus I think it's different...... For now Yeh most top end sports bike where 40mm bodies. The only difference i can find is that you need to fit a regulator to resrict fuel flow as the bike carbs are normally gravity fed from the tank.
Gareth Posted March 16, 2007 Report Posted March 16, 2007 Yeah that's all I've heard. I saw a Sierra in RC mag a while back with a home fitted set up, they were held on to the inlet with what looked like nylon tube sections and jubilee clips. Must've been specially made tho as the manifold side of the carbs have like a rib on them....
capri_boy Posted March 16, 2007 Author Report Posted March 16, 2007 Read an article on them in Retro Ford or Classic ford and they seem ok to do. Think all bike carbs are fitted with silicone hose between them and the manifold so should be easy to do. I phoned Bogg Bros the other week and they quoted £260 to make the manifold and Jet the carbs, its a bit expensive but not to bad.

Guest pistonbroke Posted March 16, 2007 Report Posted March 16, 2007 I've heard that bike carbs are better than webbers for a couple of reasons. 1. cheaoper, this is always important in my book. 2. Due to the varible venturi design, kind of like an S.U they give smoother running and better throttle response. 3. They're less likley to need regular setting up like webbers. All that said though, if your only running a standard pinto with a cam your not really going to get the full benifit of either of the two. EDIT. Al the above is based only on what i've heard about bike carbs. Never actually had any experience with them myself. I'd rather go the injection route all day long

I'd rather go the injection route all day long Yeh thats about the same as ive heard, ive also heard they sound amazing which is the main reason for going for twins!! not to bothered about performance, if i want fast i will put the bike on the road!!!!
Guest pistonbroke Posted March 16, 2007 Report Posted March 16, 2007 Another thing is bike carbs wont be as juicy as webbers. Especially important if your not worried about performance
escort21 Posted March 16, 2007 Report Posted March 16, 2007 Another thing is bike carbs wont be as juicy as webbers. Especially important if your not worried about performance Then why not stick with a normal twinchoke then and save a few hundred quid
ExotronGammaPlusSequencer Posted March 16, 2007 Report Posted March 16, 2007 The only difference i can find is that you need to fit a regulator to resrict fuel flow as the bike carbs are normally gravity fed from the tank. My R1 carbs were fed by an electric pump on the bike & this is what ive used on the 100e (my pump cost about £10) this goes straight to the carbs without the need for a seperate regulator giving you a tidyer (& cheaper) install.Ive heard people have run into problems when using facet or similar pumps with a regulator on bike carbs. Mine have been on the car a year now & they still run sweet even though ive never got round to having them set up! As ive said in other posts they drive really nice with them with no hesitation/coughing or farting (just the odd spit from cold as ive not connected the choke) Glad i bought them when i did because there was no waiting list & the price has gone up by nearly £100. If you need any info on them do a search on www.locostbuilders.co.uk theyve been bolting bike carbs onto stuff for ages
MK II Mark Posted March 16, 2007 Report Posted March 16, 2007 Bike carbs have constantly evolved whereas weber designed twin carbs are pretty old in design and need setting up far more frequently to get the most out of them... I can't wait to get mine back from Bogg's....

Hours of head scratching, injuries and throwing things across the workshop. Its fun, no really it is
Fiesta Steve Posted March 16, 2007 Report Posted March 16, 2007 webers need setting up far more frequently to get the most out of them... Do they
MK II Mark Posted March 16, 2007 Report Posted March 16, 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...

Do they Yes... otherwise you wouldn't need service kits for webers... Bike carbs are a far better design... My webers are older than my Fireblade. My webers have never been opened up. My bikes carbs have. I know just how good bike carbs are, my bike rides almost as if its fuel injected. But webers can be just as reliable. Unfortunatly they are often thrown on engines by owners that don't really know what they are doing and end up needing constant attention. Not the carbs fault.

Is your bike kept outside etc etc...

Is your bike kept outside etc etc... No, bikes kept indoors, webers are kept outdoors. Leaking fuel, and needed some attention to get them running perfect. I didn't do the work myself I entrusted the work to my local bike shop who done a superb job, like I said almost like its fuel injected now
