[clyde the ape]

Hi everyone,  I am switching to pod filters.  What does everyone do with the crankcase breather tubes??

If there is not a spot on the breather cannister under the battery box for it you can just run it to the ground. If you are worried that crud might get in there (like me) you can stick an inline fuel filter in it.Alot cheaper than buying a fancy breather for it,and it barely shows anyways

here's a link to some pics of where the hoses in question come from.  They should go to the air box, but I am not going to be reusing the box.  What should I do with these hoses??

Anybody ????

[Re-run]

That hose looks like a crankcase hose. Most just put a filter on it. Or you could just hang it out the back but that leaves the possibility of crap on the tire.

Again, you can run them to the ground or put a filter on the end. See earler post.

1980 dohc 750

The guy who is rebuilding my carbs asked if I wanted the carbs jets changed. I said I'm going to run 4 into 1 headers with a baffle and pods so, yes.

He went on a religious tirade about how crappy the bike would run with pods. How bad is bad, Who's running them on their bikes? That stock air box is the ugliest piece of tupperware ever designed. I want the pods, are we talking backfiring, decel pop, air starvation... what?

When I put my dynojet PC111 on my vtx 1800, everyone said it would run like crap. I installed it anyway myself anf took it to my local dyno tuner, they dialed it in and it runs like a raped ape. I'm thinking the same things about the naysayers on the pods.

                                              GO for it Ghost guy
  Tupperware worked for Mom WORKS fer me ,May have to change 1 day

                  But have confidants in my Mechanics ability's to get it best it can be ,
                   IF needed later,do to engine mods not looks of my Ole Tupperware

[shinyribs]

I know pods were a breeze on my SOHC,but alot of people say it is a whole different ballgame on a bike like yours. I had some cross wind issues but they went away once i got a little bigger idle jet in there. Stock was 40. I had 42's and just put in 44's the other day The 44 idle jets didnt affect idle quality,fuel mileage or anything else,as compared to the 40's or 42's.

Some say it is impossible with CV carbs,yet you see a bunch with them. I guess it all depends on how devoted you are to making it works.Sounds like you are

This what I'm thinking. After I get the bike back together and running, if my mechanic can't get it running right with the pods, I will put the stock box back on.

Shiny (or anyone), how do I determine if I have CV carbs or otherwise?

[vosachi]

so reading this the stock jet size is supposed to be 40 for the main or the pilot!? both of my jets are 68... I was told i needed to go to a 80 pilot and a 120 main jet so i can run the individual filters. I don't plan on running the airbox it's bulky and annoying any help on that would be nice

[Piute]

                                                       

                           Ya put those in A 350 Chevy or Some Ole dodge

As far as I know, if you have a DOHC then you have CV carbs. The early style roundtops and keyholes were only on the SOHC bikes. There is another style of carb on the F2's I believe.Like Piute's. Not sure what they are called.They may be Cv's,too


Roundtops

Keyholes

CV


If I got any of that wrong please someone correct me

[Piute]

Honda used two basic types of carburetors, CV and slide both made by the Keihin company. The CV type, Constant Velocity or Constant Vacuum, uses pressure to raise the throttle slide where a cable is used in the slide model.
                   me Keihin CV Carb History, and Design Specifications
Keihin is a well known carb maker in Japan, that has been making CV (constant velocity) carburetors for motorcycles for many years. Unlike Mikuni carbs (similar to Amals), which can be finicky, hard to tune, and generally offer primarily top end performance as their specialty, the Keihin CV carb is designed for better all around drivability. Honda has used them exclusively since the 1960's. As you know, Harley-Davidson (H-D) struggled for years with poor carburetors untill 1988 when they had Keihin design the 41mm CV unit that is still used today. It comes on everything from their little 500cc Buell Blast, the Sportsters, and all of their Big Twins. The only differences are in jet size, and fuel needle choice. They have installed millions of these carbs on their bikes with great results. Indians are very similar to modern H-D's, where carburetion is concerned, so the Keihin CV is a good choice if the rider wants to step up to more power, smoother running, easier starting, and better milage than the original Linkert carb. Because many H-D riders replace these carbs with larger, performance carbs, they can be easily found for very little money, and in very good shape. They can be found for less than $100.00 complete!

Well thanks for all the replies. I have my carbs at a carb builder. heres what he said. He has rebuilt and tune some 500 carbs for bothe the sohc and dohc. It is his experience that only the strong of heart and strong of mechanical skills should use pods on a dohc. He's an expert and he can't get them running right for very long. He said definitly stay with the stock air box. It has magical powers, for vacuum lines to keep everything running right.
So, I'm keeping the stock air box on. I will have to rethink my build.

                                    cover the pods with clear plastic wrap

I was thinking duck tape.
