Dellortos are quite widely available in Europe, these carbs are used as stock with Motoguzzi, BMW, Laverda, Husaberg, Husqvarna, KTM and Ducati. They are available 34, 36, 38, 40 and 41mm. Theys are also equipped with accelerator pump.WoW! where did you get Dollerto's for your Bonnie? I had Dollerto's on my 69 VW Bug.
Advantage against what? Against stock ones it is the same as with any bigger carb (Keihin FCR, Mikuni TMR).Advantage?
Should not be a problem. I have done it previously with Dellorto to one Ducati SS (bigger PHM40;s instead of single DRLA), One Honda XL500, one Honda 600 Dominator and One Husaberg ( bigger pump carb instead of stock non pump type one). There is nothing strange with it and I have access to all needles, jets and slides for tuning.good, now let's see you tune them, sync them properly, and post a dyno run with some quantifiable results.
Hi Mike,I think they will make better hp then stock carbs but not as much as flat slides .Most times you get what you pay for .I think a flow bench and a dyno would tell you that.
4mm os valves,for someome that wants to save money is going to be pricey you will have to but some way bigger valve seats in they will be about touching each other.I am not sure i would want that big of valve on the street.Why would you want them with that small of carb anyway? 1 or 2mm os will take more air then those carbs will flow.
I will ask, Thanks.well all i can tell you a 2mm over intake valve is about the same size as the out side DIA. of a stock valve seat .A 4mm intake will be hanging over the seat by 1 mm on each side.I know this cause i had my intake seats replaced.You might want to ask him if he is aware of that.
1. Throttle is ok, it pulls 42-43mm, enough for these carbs.So what are you using for a throttle & cable setup ?
