ok so ive been asking around and still havent got some answers needed. Im in the process of guttin the 550. everything is off, cleaning is what im doing now. My main ?s are this: im planning on installing 4-2-1 exhaust..carbs have been recleaned. what jets should i put in for starters?

im using a 38 now and plan on having pods. Also the airbox had 2 hoses plugged into it.....what happens to these hoses??? do i pull them off or what??
Last question for now is any suggestions on the fusebox??where do i put this?? do i need the fuses??..i had a friend say i dont need them and he doesnt have the fuses on his bobber bike..well at least i could not see. Also the battery...Im not very electricall but would like some info on where and how to move it??? am i cutting wires and what should i do and not do??? I really am asking for some indepth answers if possible, i cant seem to get anything useful besides some slightly odd comments that doesnt help me out.

thanks for any useful help!!!!
bike is a honda 550 1976

Do you have any pictures of your bike in progress ?

yes lots..how do i post?

at least you had the good taste to butcher one of the later year 550's you need to have at least one fuse there is a simplified wiring diagram that has been posted on the forum that will work for what you want however with the three phase alternator you must have voltage to make voltage so no voltage no spark which means you must have a battery
I have seen guys put the battery in the triangle next to the back fender with a cover that looks good if you want to use the electric start
If you do not want to use the electric start you can get a small battery and put it under a hump like for a cafe bike seat

I will warn you this those carbs are made for still air and unless you use the antipods you will have a devil of a time making regular pods work with them which will chew up a lot of riding time trying to figure out why the bike will only run well at one given speed
compromises can be made for decent driveability but it will never run well at all speeds

these carbs need the laminar flow of the airbox designed for them
another option is to get cv carbs of of a 650 and use those they will not care so much about pods

also in the spirit of helping you download the manuals for the bike on the forum here

wow....thats kinda scary and darkening my hopes on this project. do u suggest keeping the air box?? i really wanted the triangle. why is it people can make these bikes look so sweet but its such a #$%*

??
I heard i dont need a battery, well if no battery how would electrical charge the speedo?? im not very well at electrical diagrams...i just wish i could shove this fuse in the corner. im so used to track riding and newer aggressive riding bikes, the simple ziptie is notorious with us and i dont want to dothis on this project. i really want a sharp bike
*** i got lost on the alternator and voltage part.... **** i just dont want my bike to be aproject thats a bail out. im so far into it now and really want this to work out like no other!! what do you suggest the best alternative for me is?? just say f it and stick box and battery back?? i dont want to but i guess it is what it is.

Can you explain this

What kind of charge does your speedo need

Yes you need the fuses.

i see. does anyone have the answer for those two hoses going to the airbox that would be hanging out with no home??

messeduptriple · « **Reply #8 on:** January 10, 2012, 08:28:49 PM »

so you say f it and try the carbs of the 650?? what year..sorry if these ?s aredumb just want to know specifics..im guessing 76 right???

messeduptriple · « **Reply #9 on:** January 10, 2012, 08:44:33 PM »

to reply with the speedo i did want to buy a new l e d digital speedo for it. will i still need the battery???

We're here to help, but when your first posts asks many questions without details, you will not get in depth answers.

You post you want to install a 4-2-1 exhaust and want to know what jets to install?
What kind of exhaust??

Start doing your research. Search. Read, read again. If you want to do it, it's aleady been done. Try posting one or two specific questions rather than 6 or 7 general ones.

Good luck.

luap When you kick your bike over to start it up what gives power to the coils? I don't know much about the 550. But my 750 needs a battery to start even with the kicker.

Yes I'm sorry I plopped in many questions but those are the main ones I can't get answered

You're biting off more than you can chew at this point. Slow down and spend some time learning how your bike and its individual systems work before you start trying to re-engineer them. That way you know where you're starting from and you know what you can and cannot do. Jumping into modifications like you're talking about without the experience and knowledge needed to tackle them correctly is a recipe for an unfinished project you end up having to pay somebody else to take off your hands. Take your time, learn about your bike, and do it right.

And yes, you must have a battery for your sohc4 to run, even if you're only using the kick-start.

hey bud I was not meaning to be discouraging but without converting the alternator to a fixed magnet type you need a battery and any of the cv carbs for the 650 sohc bikes would work and could be jetted to your needs the problem is what jets you need depend on how loose the exhaust is and how unrestrictive or restrictive your intake is as said by others if you want to do a build you need to do more research on how the bike should be in its stock form before you go making modifications I and others would be glad to help in whatever way we can but don't get too far ahead of your self and by the way if you are going to sell the side covers I would be interested

Danno · « **Reply #19 on:** January 10, 2012, 11:50:55 PM »

sorry I forgot to answer your question about the hoses one is a drain hose for condensation and should have a fat part when you squeeze it it opens and drains it is on the lower right the other is a vent hose for the engine and comes off the valve cover to let blow by out and condensation it needs to be plumbed either into one of the pods to be reburnt or it can be strung to the back by the fender and pointed to the ground to let the condensation out

Danno · « **Reply #20 on:** January 10, 2012, 11:57:53 PM »

as far as your jets are concerned if you don't take the baffles out of the exhaust then a starting point with pods would be 115 mains and 40 slows but the mains with pods could end up 120 or 110 still 40 slows and move the needles up at least one notch (you move the clip down to move the needle up) to do this with pods you will need at least a 42 slow jet a 40 slow jet and 110,115,120 main jets and you will have to experiment to figure out which one you need I have seen a lot of different combos used with pods none are good with everything you just have to get it where you like it most of the time

messeduptriple · « **Reply #21 on:** January 11, 2012, 04:26:19 AM »

What will the bike do if it doesn't like the jets and things arent working well together?? What should I be expecting ? How will I know to go up or down on jets?
I think I will try this and I hope to learn what works and stuff. Sounds like its work and that's ok with me.
* I'm not sure what 4-2-1 exhaust to get yet.

at least you had the good taste to butcher one of the later year 550's

Wat'chu talkin bout Willis? 74 - 76 are the best years. 77 and 78 would be considered later. Depending the condition when he bought it would be a shame to butcher a good resto bike. It has all the goods like exhaust, original paint and seat pan. A good seat cover and euro bars could've made a nice original.

As far as after morket exhausts and pods and all that 'stuff' it will be trial and error on your part. Most of us cringe at the mention of pods. They're pretty much for looks not performance.

Pretty red chain. You going for some kind of theme there with the frame or tins?
