Octy with inlines?

[Redshirt]

Ive been digging for a while to find out how to route inline filters with an octy.
I found this thread
http://www.xs11.com/forum/showthread...ight=fuel+line
and Im not sure if any of these diagrams apply when an octy is involved. Some are mentioned as having a "manifold" and Im not sure its refering to the octy assembly.

Im trying to keep the octy. My tank is being coated but an additional precaution seems good since the tank was pretty nasty looking.

Any diagrams on routing with octy?

Ys instead of Ts

We are working that on the naked boy right now. We sourced some 1/4 plastic Y fittings to replace the standard Ts that are used in the stock routing. We use Tygone tubing which will kink if you try to tight a bend. When Salty gets it figured out we will try and take some pics. Not going to be today as its going to be nice enough to ride today and tomorrow

Excellent!
My octy was working (apparently) when I got it. I opened it and removed some gummed fuel by just inspecting and screwing it back together. I didnt pull it apart or remove the innards so Im supposing it will still work.

Actually, now that I think of it, I had a fuel drip into carb 1 (the kickstand side). This was prior to carb cleaning but Im not sure this is an indicator of a problem up the lines/octy. The petcock was set to on most of the time, but I turned it off and this reduced the amount I saw drip through the podded carb 1.

When I was draining the tank, I turned the petcock off and had no drips. So I dont think they are the problem.
Anyone have any ideas on that?

If you have a carb that is overflowing when sitting it means that both the octy and the carbs float valve has failed, and if the petcocks are off and still overflowing it means the petcock has failed as well.

You say your petcocks didnt drip when disconnected and off so they are good. From your other thread you said you cleaned a lot of crap out of the float screens so that may have been what was causing the float to leak. You say you cleaned some crap out of the octy and that may have been what was causing the problem there.

You said before that you were getting carb kits didn't you?

[Redshirt]

yes. carb kits are installed. The leaking was with the POs dirty carbs et al. The new carbs havent had fuel put in them yet. Carbs are assembled now, but Im stil working all the other little issues as I go and the tank is being lined right now.

A good comparison for me of our bikes fuel system is like your kitchen sink. You have shut off valves under the sink, they are just there to shut off the water when you service the faucet or leaving for a long period of time just in case. The faucet is what turns the water on and off as needed during normal use.

For our bikes, the float valves in the carb are like the faucet, the petcocks are like the shut off valves. The octy is an added shut off valve just in case the petcocks leaked, or you did not turn them off. It just happens to be very handy that it works off engine vacuum.

If your kitchen faucet drips, you don't replace the shutoff valves, you work on the faucet. Same thing for the fuel system, if the carbs overflow, the float needles are not working correctly.

Now just like your faucet, it may be that the shutoff valves also do not work and need some work to.

I still have the Octy installed. 90º Filters installed below airbox boots.

Haven't seen filters like that, I like!

[wingnut]

Those are neat filters. Opens up a couple of options. Were did you find them?

The have a list of dealers.

Sweet, thanks!

rpgoerlich,
So put the filters on the line "to carb 1 & 2" and the other on line "to carb 3 &4?
Im guessing you used 90 degree filters because of the space constraints. Is that true?

Im looking at the octy routing in the book and trying to figure out the best places to put the filters. I have the straight through filters (no angle). Might just be out of luck?

That's correct. I just turned the fuel "T" down a bit to take the strain off the line and filter. Now granted these aren't the best filters out there but with them lower than the carbs they tend to trap everything there.

I have used straight filters but had problems with them cracking due to the strain on the lines and plastic unless you run them like TC diagrammed in the earlier link feeding opposite sides. I also like to be able to replace them without having to pull the tank and all. They're kinda hard to get to when they are between the air box boots.

The local Yamaha dealer as well as an independent cycle repair shop stocks them here. Cost is a couple bucks each. They go quick as I usually buy 6 at a time off the display along with a few other folks it looks like. Most times I end up grabbing the rest of the display.

So you run the octy but have the filters after it? Wouldn't it make more sense to filter it before the octy so that something doesnt get in there and hold it open?

[DGXSER]

Nate, it could make more sense, but I'd be danged if I could find room or make a routing to fit them in there.

Redshirt, I have straight in line filters that I put in the fuel line as it goes down between the air box boots. They fit between them fine. I do not use the octy, but the lines down to the carbs is pretty much the same with or without it.
