twin 40,s with a CVH

[HandyAndy]

i,ve looked thru search facility but didn,t find anything, so as per title.... will a set of twin 40,s work with my CVH 1.8 engine ? if so what is involved apart from getting a manifold to match up?
sorry if this is a basic question but i don,t know the in,s & out,s of carbs/fuel set ups.
thanks in advance

i wish the bike i have sat here doing nothing had its carbs in nice straight line but alas they are a "V" layout for my V4 honda,
i,ll look out for some cheap bikes carbs & a manifold plate from "shortrack", tho to be honest it still confuses me how to put it all together :o :confused: :D

Andy,
There is a breakers next to me I can go ask what a bank of 4 carbies is for quids, as for a manifold think of how they fit on the bike and make it longer..one end to fit the car motor the other the bike carbs but apparently you have to have each tube the same length so will mean adding to the throttle doodah and making the bracket longer

I think you need to get carbs off a bike that produces around the same horsepower as your expecting from your car engine.

:D what? you mean i can get 250bhp???? carbs :D , i wish, from a cvh engine i think i,ll be happy with about 125bhp.

i,ll keep my eyes open for some 600 bike carbs as they seem to be popular.

Andy,

I am in the same boat as you, I went so far as to buy an dual weber intake manifold for a 1600 CVH hoping to be able to put a plate between it and the engine to block off the different water ports but it turns out that the intake ports themselves are in a different position so are about 10mm out. WrigglyPig has made a manifold for bike carbs for his and I have asked him for the cad drawing for the plate he used. I am still contemplating whether to sell my webers and go with bike carbs or to try to make a manifold for the webers.

If you figure anything out then please let me know, I'll do the same.

[RAYLEE29]

what i meant was if your realistically looking at 100 horses from your car engine then look for a bike that produces 100/125 horses as the carbs will flow the correct amount of fuel and air
and as everyone knows horsepower is directlly linked to the amount of fuel you can burn!

Ray, sorry about my rather strange humour, just me being wishful thinking as i,ve only got the cvh engine for now, tho once thru iva that,ll be swapped for a new zetec 2ltr,
thankyou for your suggestions, i,m trying to read up on bike carb info as i know zilch of how to adapt them to a car engine, bikes yes, cars haven,t a clue how to make a setup work.
cheers

Andy,
Think of the car motor as a big but ugly bike motor.;)

[HandyAndy]

ugly & dirty too, :D spent day cleaning my engine , got it on an engine cradle so at waist height so makes it easier, any luck on any carbs from bike breaker?
had a big clean up in garage in prep for doing & finishing the back end.

Its ok had four kids driving me mad yesterday :mad:
try looking at bogg brothers theyve been playing with bike carbs for ages
600 carbs should be about right
there was someone on here that did some
im sure someone on locost builders has done some too

Well wrigglypig cannot locate the cad files so looks like I will be making the plates myself if it turns out easy enough I would be willing to make one for you too Andy. Time will tell :)
