While I gather replacement hoses for the octy, I capped both PRI ports, with lines installed on the other ports and used the inline T's to tie both sides together. Just make sure and shut them off when you park it...

**81xsproject** · 02-23-2009, 08:36 AM

I also recomment capping/plugging the prime ports as you will no longer need them. Without the octy, they are always on prime. I have mine setup so the lines from the petcocks T together, then go throught a filter then T back out to the carbs. Simple, works fine, and allows you to run on a single petcock.

I have mine so the right petcock feeds the T between 1&2 carbs on left and the left petcock feeds 3&4.I also left enough line on each one so I can pick the back of the tank up and stick a 2/4 under it and adjust and sync the carbs without completely removing the tank.I have no inline fuel filters but did put new petcock screens on them.Works great.
For me I was trying to simplify the spagetti network of lines so I didnt want add another T just run the petcocks together.

The down side of ditching the 'pus is ...

the fact, after having done it to my bike, I occasionally have forgotten to turn the fuel taps to 'OFF' when I park.

This has resulted (for me at least) in a couple of extra oil changes from the gas drainage into the crankcase. It is nonetheless understandable as I ride a Standard about half of the time which uses a different system not requiring any input from me. Initially, in my life with this bike, I was taking the tank off and on so much that the 'pus was drivin' me nuts as it is a PITA to re install the tank with the damn thing in there. No need for frequent tank removal these days sooo ...bottom line is: mine is goin' back on real soon.

... which would be a float valve problem... not a missing octo problem. On the days you don't turn off your petcocks, it still SHOULDN'T leak. I realize an octy is another added insurance policy, but just not worth the headache to me. You can remove it, and it takes you forgetting to turn off your petcocks AND have leaking float valves to have a problem.. or leaking petcocks and float valves. The FIRST time I had a problem with either, I'd be in there fixing the problem after my oil change.

Yeah ... I lowered the fuel level in the bowls a hair each time ...

The FIRST time I had a problem with either, I'd be in there fixing the problem after my oil change.

but eventually some fuel would seem to seep it's way past the float valves .. especially when the tank is plumb full and it sits on the sidestand. Since the needle and seats were brand new; I figured that just might have been the reason why Yam engineered a vacuum shut off in there and didn't offer it as an option. Hmmm ... but what would I know?

or leaking petcocks

To my backwards way of thinkin', I figured that: if shuttin' of the fuel taps stopped the leak to the crancase, at the very least, THEY, themselves, work, right? Just the way I looked at it ....

Which means you would still have a float valve problem, and is why they recommend doing a leak test on the bench before re-installation of the carbs.

I never said it didn't work as designed, but a THIRD thing to prevent a problem seems a bit repetitive to most.

I appologize if you took anything I wrote to you as a personal attack. No bad intentions were meant. I was simply pointing things out for the original poster's benefit.

Interesting, Tr .. don't think my FVs are bad though ..

Didn't realize that there was so much redundancy built in ... who woulda' thunk it? .... I'll bet ya' dollars to donuts though that the majority of riders out there who have dumped the 'pus find it important to shut off the fuel taps when stopping for long periods .... possibly there's another reason for closing them that I'm unaware of? Frankly, I don't understand why anyone would even bother turning off taps if something untoward didn't happen by leaving them on .... just my back'rds way of thinkin' again, I guess

.... this has been discussed many times here since I've been reading this forum and working on these bikes ... that's only been a little more than a couple of years ... so I have not seen it all ... but that is what I think I've learned thus far.

Actually, we could post a poll if it hasn't been done already ... see who does and who doesn't think it's necessary to close the taps .... Here's a thought ... as you know, Ben Franklin has long been considered one of our nation's wisest men. Whenever ole Ben found himself facing a difficult decision, he used he write down all the reasons TO do or NOT TO do something in two different columns .... then ole Ben would simply count the reasons in each column and his decision was pretty much made for him ... maybe the the original author of this thread might want to use a modified version of the Ben Franklin Balance sheet based on the poll; he could count the DOs and DON'TS and thereby decide if he should shut off his fuel taps or not once he pitches the octy ...???

... and stop attacking me too, ya' old meany

Go find a bear .... or something more your size to pick on

Where's Prometheus?

I havent shut my petcocks of since last year.I always forget.I havent had it leak yet.
However now that I say that I'll go out to the garage and have gas all over the floor.

**DGXSER** · 02-25-2009, 09:31 PM

F I N E C, I go through it everytime (ok ALMOST everytime) I get on and off the bike. (Part of the MSF course). F=Fuel. The biggest thing I forget is sometimes turning it ON when I start it. Amazing how much is on those bowls. I can get it started and warmed up and make it to about 1/4 mile from my drive. But after developing leaking carbs a few times, I have so far not forgotten to shut it off!!

**81xsproject** · 02-25-2009, 09:48 PM

Not that he needs the ego boost

, but Tod is correct. If I forget to turn off my petcocks, I can come out days later and no gas has leaked down full tank or not. Like Tod said, no one is picking on anyone, but float valves shouldn't leak, period.

**DGXSER** · 02-25-2009, 09:53 PM

Float valves

They should not is right, but since I have brand new ones, and have had them be fine one moment and next time I turn the gas on leaking out the air box within a ten minute time period. I'll stick to my routine.

You have an easy problem, no fuel filters and junk in the seats, or the floats are not set correctly, and on the side stand hang up on the side of the carb and NOT shut off.
JMHO

( I know, just like @ssh0les, everyone has one, and most stink!)

**petejw** · 02-26-2009, 12:02 AM

Ive had my bike for over 4 yrs and the first thing i did was
get rid of the occy. I never turn off the fuel taps and the only time it did leak i had a broken float post.
In my opinion fix the cause not the symptom.
