Steelies Posted December 9, 2012 Share Posted December 9, 2012 ok, i want bike carbs on my stock bluetop, in a KP60 starlet. currently running SUs haha yuck someone has offered me dellorto sidedrafts in exchange for labour... but i really like the idea of bike carbs! - both options require making a manifold. - it's a little tight for space in the KP, dellortos are somewhat bulkier than a set of motorbicycle carburettors. another quick'n'easy option may even be to put smaller SUs on so it's not so over carbed. currently running twin 1.75"SU from a trump 2500 and pouring gas in, and out. anyone have any pearl necklaces of wisdom on this?

ryanfels Posted December 9, 2012 Share Posted December 9, 2012 I have no personal experiance with bike carbs but the manifolds look super easy to make as they are just a flange with some curved pipes welded to them and the bike carbs just attached using some silicon piping. From what ive read, they just need a fuel regulator to get running. im not sure on playing with the jets though I vote get dellortos, sell and buy bike carbs Quote Link to comment Share on other sites More sharing options...
Rookie Posted December 9, 2012 Share Posted December 9, 2012 I really like dellortos and bike carbs, but given the choice I would probably go with the dellortos, just due to the fact you are able to get a smoother drive across the board because of the 5 circuits compared to 3 in bike carbs. In saying that either can be made to drive well, and if you are really tight on space then the bike carbs may be the only option. Don't know if this has helped or not haha Quote Link to comment Share on other sites More sharing options...
Steelies Posted December 9, 2012 Author Share Posted December 9, 2012 helping indeed, chur! heh i would sell the dellortos but as they'd be a hookup from a friend it wouldnt be right. theyre on the L16 Jake is replacing with the CA we just picked up from your ways Quote Link to comment Share on other sites More sharing options...
peteretep Posted December 9, 2012 Share Posted December 9, 2012 Running a standard carb fuel pump you shouldnt need to fit a regulator. Most carbs(bike or other) need ~3psi so you can measure your current fuel pressure if you want. Me and stephen set up his bike carbs with a wide band just driving around the streets and a set of jet drills. You set up the idle fueling with the needle height. In my escort the economy cant be complained about, its not bad at all. There is probably more to be learned about the little ports at the inlets of the carbs but they dont seem to have a big effect on normal running, the ports would normally be inside the airbox but all setups I have seen have them looking at atmosphere. One thing which is different with bike carbs is the linkage is smaller than a car carb which means a shorter pedal movement in the car unless modified. There isnt a problem with either setups but for me, I would go for bike carbs as they are cheaper and newer, new sidedraughts cost a bomb and old ones are all pretty worn from what I have seen Quote Link to comment Share on other sites More sharing options...
Goat Posted December 9, 2012 Share Posted December 9, 2012 Asthetically, dellortos would look super choice. Make it looks like an early 80's race car. Hah. You also get that "fwoar" factor, cos dellortos/webbers are big boys toys. But for ease of manifold, and minimum space, bike carbs will be the beeze kneeze. Probably a million recepies for how to jet all sorts to suut 4age on the interwebs too/probably dont need to change a thing/lift the needles up a tooth or two. 1 Quote Link to comment Share on other sites More sharing options...
rot808 Posted December 9, 2012 Share Posted December 9, 2012 Bike carbs I rection •Look cool •Sound cool •Sounds cooler saying bike carbs •Look cool •Jet drills is all we used to rejet mine with wideband •Didn't bother fitting a regulator and it works fine (I'm lazy) •Look cool •Manifold is easier Edit: dayum beaten by fuckloads Quote Link to comment Share on other sites More sharing options...
phatt20 Posted December 9, 2012 Share Posted December 9, 2012 iv used both, would almost have to say go the dellortos just for the fact you can buy an off the shelf manifold to suit so saves a bit of fucking round. most dellortos are gettin pretty long in the tooth tho so i would recommend buying new webers or similar. bike carbs tend to be better on fuel and are a lot smoother due to being a cv type carb, easy to jet, and cheap. so really depends on your fabrication skills / hook ups/ preference really. i would go sidedrafts on a 4age personally.

phatt20 Posted December 9, 2012 Share Posted December 9, 2012 oh and bike carbs give ya more room non restrictive for air cleaners ( as long as they are the semi downdraft type) Quote Link to comment Share on other sites More sharing options...
Steelies Posted December 9, 2012 Author Share Posted December 9, 2012 wicked , all good info thanks good point about side draft condition as they arent new thats for sure. i can make a manifold cheaper than buying one, so i'll do that no matter which choice. i'll measure up and see how tight the dellortos will be. i currently have filter problems so keen to get actual filtration on there with the carb switch. but currently leaning towards bike crabs.

peteretep Posted December 9, 2012 Share Posted December 9, 2012 It depends on which carbs you use, but bike carbs arent the easiest thing to fit filters to. Best bet would be to look at how the filter is fitted on the bike then try to copy it, as bike airboxes are usually some weird shape that wouldnt work in a car Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted December 9, 2012 Share Posted December 9, 2012 Use a click clack lunch box with panel filter in one side so you can remove it on the fly when you want extra doort. I agree with stephen about everything. Bike Carbs. Quote Link to comment Share on other sites More sharing options...

Steelies Posted December 9, 2012 Author Share Posted December 9, 2012 filter will be an issue because of brake booster, strut tower etc. fitment to carb is all G, do that stuffs all day at work anyway. anyone know about stationary airboxes and flexi panel to allow carb movement?

peteretep Posted December 9, 2012 Share Posted December 9, 2012 just use some foam around the intakes to make a reasonable seal Quote Link to comment Share on other sites More sharing options...
shaneo Posted December 10, 2012 Share Posted December 10, 2012 I have had a few people tell me I should run an air box for the bike carbs then others tell me that there should be enough draw so they wont need one. I got some motor cross air filters for mine and I don't run a fuel reg either. I vote for bike carbs they sound and perform very well.
