Dan M Posted January 31, 2008 Posted January 31, 2008 Thought you might like this Very cool. I wonder how it runs.
DeBenGuzzi Posted January 31, 2008 Posted January 31, 2008 but where do the air filters go? uh-oh, rachet aint gonna like this . . .
Guest ratchethack Posted January 31, 2008 Posted January 31, 2008 I'm no expert on side-draft auto carbs, but is that a Weber DCOE?
Ballacraine Posted January 31, 2008 Posted January 31, 2008 I dunno, but it sort of reminded me of the ghastly WAL-Philips 'Injectors' that the old boys used to put on their sprint Triumph twins & the like. Nige.
Ballacraine Posted January 31, 2008 Posted January 31, 2008 Really not sure about the mile long inlet tracts TBH It is a neatly done job though, by the look. Nige.
emry Posted January 31, 2008 Posted January 31, 2008 Looks like a Dell'orto DHLA. Harley guys love them, more fuel, more noise, more power!!!! I saw a 100inch HD with straight pipes run on a dyno years ago. It shot 2 foot flames out the exhaust when it was wide open and made a whoping 48HP!!!! We about wet our pants we were laughing so hard.
Dan M Posted January 31, 2008 Posted January 31, 2008 Really not sure about the mile long inlet tracts TBH Nige. Long runners are usually good for low end torque but hurt top end. It would be interesting to know if it actually works.
Ballacraine Posted January 31, 2008 Posted January 31, 2008 If emry's post is anything to go by.... I would doubt it! Nige.
Paul Minnaert Posted January 31, 2008 Posted January 31, 2008 A front picture would be nice too, look at the angle the header pices are, and where the silencers are. Maybe someone has been making calculations and found this to be optimal?
felix42o Posted February 1, 2008 Posted February 1, 2008 If nothing else it's a very clean look. I like it. I would think that 2 carbs would be better than one for tuning's sake, however.
macguzzi Posted February 1, 2008 Author Posted February 1, 2008 I'm no expert on side-draft auto carbs, but is that a Weber DCOE? Think it could be Dellorto will check, it is a V7 sport
lavrgs Posted February 1, 2008 Posted February 1, 2008 The seat looks comfy...am I banned for saying that?
emry Posted February 1, 2008 Posted February 1, 2008 I think that the intake length should be close to correct, if I recall from another thread our current intakes are to short. The DHLA's actually are two carbs but they use a common float chamber, each side is individually tunable. I just had to tune up an old Lotus Turbo that used them. The HD I saw belonged to an old grey beard, he was certain that his HD made more power than my Kaw GPz900. He missed out on the whole tuning thing because his carb was about two inches from the valve (common on HD's) and his exhaust was about three feet long and two inch in diameter. Beyond the flames it also holds the record for the loudest motorcycle I have ever been near. It was running in a Dynojet chamber that it left burn mark on the wall of. We were outside the "sound proof" chamber and it still hurt my ears!!! By comparison you could talk normally when a standard bike was running.
