Re-route hoses

[rishardh]

When you T the two breather hoses from the cylinders wont it push air from one cylinder to the other?

Looks great stewart! Copy away!
Suckers r heavy aren't they.

 

[stewart2]

Yes they are! I'm thinking about putting one on the other side, right across from it just for looks. And it does turn heads, especially going on bases.

That is why i used a Y-connection, so the flow has to go downwards.

What would happen if I put a catch can before the filter. Not after. I'm not to mechanically inclined.

Could a person use fuel vapor hose instead of transmission oil cooler hose for this type of application? I understand the transmission oil cooler hose can withstand higher temperatures (~300F as opposed to ~250F) and higher pressures then the fuel vapor hose, but it doesn't appear there will be a large amount of hot oil running through this hose...

It'd be fine as I've seen many with the filter mounted on the catchcan itself.

Why when rubber fuel line is black and cheap.

Well, I already have 5ft of 3/8" black rubber fuel line (i.e., fuel vapor hose) and I'm wondering if that will work, or if I will need to hunt down some "transmission oil cooler hose." Both types of hoses look the same on the outside, its the inside thats different. I'm wondering if the black rubber fuel line will be exposed to temperatures around 300F.

 

[Stevenc150]

You had me confused as most of the "fuel vapor lines" I've seen were small diam. and steel. The fuel line is what I used and have had no probs whatsoever - just be concious of your routing and you'll be fine.

Just did the modification yesterday. Worked out great. Loving the smoothness.

 

[tedstang]

im so damn confused you guys make everything so hard to understand!!!! let me make sure i got this right you take the 2 hoses, connect them to a y pipe then run a line off that to the rear with a filter mounted somwhere on the line? now my question is do i need a filter and catch can. i see if you have a catch can you need a filter but i just did mine and havent started it up yet because i have no filter or catch can just a line with both hoses running to the back.[confused]

Just thought i would add a couple pictures of how i did mine. I ran them to the front and did a filter and a plug. The plug is just a large bolt that was the perfect size to fit in the line nice and snug. The line runs to the front, down, and through the little opening on the bracket for the oil cooler. This way, the line doesn't require any zip ties to hold it in place. Also, the filter is then tucked nicely out of view between the oil cooler and the motor.

I covered the chrome of the filter with black duct tape considering nothing else on my bike is chrome.

A 5/8" tee doesn't even come close to fitting inside of the 2 hoses in the airbox you need to connect together with the 1st tee.

So I put the bike back together now and go back to the store.

We'll try 3/8" this time.

 

[ny_driver]

So....after going and getting some 3/8" hose and T's in my truck, I was able to finish the project.

I think it feels smoother in 1st gear for sure.

Here you can see how I spliced my hoses.

How I plugged the holes.

How it looks finished.

How the chrome filter matches my aluminum Jardine close enough for me.

I did this a little differently. Run both breathers into one 3/8" line with a T, then ran the fuel evaporator hose into another T (it fits snugly into the the 3/8" line, or you could use an adapter) and ran them both down into the original fuel overflow pipe, which exits neatly at a stock location. Very clean, no added dangling hoses/parts. Need only three new parts from True Value, and a bunch of zip ties:

1. 2x 3/8" nylon Ts.
2. 1x 3/8" to 1/4" 'mender' adapter.

No extra 3/8" fuel line, no 'catch can' or breather filter. Used the original 2x 3/8" hoses, and had some left over.

Just did this and noticed one hell of a difference. Thanks for the write up![up]

I know paolosica's post is very old but I just got to say I recommend this mod is not done the way he did it. When there is a fuel overflow, it could back up into the engine. I know, It will flow down hill and the breathers are one way valves, but it's just not a good idea. There is a chance fuel will get in to the crankcase. Just fair warning.
