#134339 Flashback (Moderator) The devil to pay, and no pitch hot Moderator Posts: 4591 Re:Mikuni 42 HSR Flatslide Carburetor 2 Months, 1 Week ago   That looks incredible. Its a fine tuners dream come true. That's what I was thinking too..very simple to adjust all the circuits..I think Randysgym has one, but I don't know if he has installed it yet...   Logged       The administrator has disabled public write access. #134420 erizo (User) Gold Boarder Posts: 652 Re:Mikuni 42 HSR Flatslide Carburetor 2 Months, 1 Week ago   Gram wrote: Only saying if because I am also looking into S&S and Weber options too. I really like the Weber but it is going to require a lot of mods to work with the Road Star, and the S&S needs manifold adaption. So the 42mm is going to be the easiest route. i fitted a weber to an electra glide last week. VERY nice carb, far superior than the keihin, a bit of a bitch to fit and sticks out a bit, but lovely smooth power delivery. better than the S&S, which i´ve found to be a bit lacking at the bottom end and bottom midrange. they can be a bit juicy though. the webers are being made 200mtrs from my shop i spoke to the rep last week about the possibility of a roadie adaption, and he said he´d get back to me, so i´ll keep bugging him as much as i can and see if i can blag a freebie to fit on mine for testing.   Logged     be realistic - demand the impossible!   The administrator has disabled public write access. #134425 Gram (Admin) Musky took my beer!

I've spoken to the US folks, but as you can imagine they are not much help for this project. I really like the tunability of the webers. Thinking of the 48 DCO SP, and running each barrel back to an individual cylinder. I can't get any reasonable information on the new motorcycle carbs at all. I would really like to see a shematic for one but the us site does not list them at all. Do you remember which carb it was?

I have a flat slide and love it. however, the hsr has no accomodations for the tps unless you mod it somehow..I use a voes instead...but I've heard thru the grapevine that a member is currently writing up a tech article that will address this...I'm anxiously waiting.. Here is a link to a couple of different way to modify the HSR to accomodate the TPS. http://good-times.webshots.com/album/562849257IwUXNQ?vhost=good-times&start=0   Logged       The administrator has disabled public write access. #134467 eblack (User) Don't force things, just use a bigger hammer Senior Boarder Posts: 202 Re:Mikuni 42 HSR Flatslide Carburetor 2 Months, 1 Week ago   Gram, Thanks for all the info., I've come close to purchasing that carb. a couple of times but $400. is alot of $ and it seems to go elsewhere. Didn't know about the 40mm/yamaha connection. My 40mm w/ it's 2.5mm float valve is working great, so putting a 2.5 in a 42 does sound the easiest route. During my research I just looked at the super E's&G's they seemed incrediably simple and very user friendly. The aftermarket world does revolve around Harley doesn't it.   Logged       The administrator has disabled public write access. #134544 erizo (User) Gold Boarder Posts: 652 Re:Mikuni 42 HSR Flatslide Carburetor 2 Months, 1 Week ago   Gram wrote: I've spoken to the US folks, but as you can imagine they are not much help for this project.

Gram it was a single barrel 45 normally i don´t reccommend more than a 42 on a bike below 1800cc due to the lack of vacuum in the venturi at lower revs making the power delivery a bit poor, but as the weber has the atomiser in the middle of the venturi, the 45 worked perfectly on the 1340 glide. here´s a couple of bits of info.... http://www.webcon.co.uk/weber/perf_operation.htm http://www.teglerizer.com/dcoe/weber_service_manual.pdf it may be worth getting in touch with david `bulldog´ tice who used to do tech advice in the barons websit. he runs a DCOE on the beast. if i get some more info in webers for roadies, i´ll post it up   Logged     be realistic - demand the impossible!   The administrator has disabled public write access.
