YICS eliminator question

[jwhughes3]

rifle cleaning kit

Smash to clean that YICS passage you might get an inexpensive rifle cleaning kit at Wally World and use the bore brush (.300 cal) to clean the passage.

There is a thread on syncing with a single vacuum gauge (which can be rented/borrowed) at an AutoZone or OReillys / NAPA etc.

Did you even out the butterfly's when you had the carbs out the first time?

I would bet that the little bit of white smoke was just the oil that you stired up from installing the eliminator being burnt off.

Ok.

Can anyone advise as to why the bike ran so incredibly poorly with the eliminator installed? clearly need to figure out why as it needs to run with that installed in order to sync the carbs.

Nathan - thanks for the thoughts on the white smoke!

Have access to a motion pro, just not sure if I've got the right adapters.

Actually had a friend who offered rebuild the carb. I am sure that he did, he's a mechanic. When he offered to rebuild it for the cost of parts, we jumped at the opportunity.

Without the eliminator it will even out the vacuum across the cylinders causing it to cover up sync problems. When you put the eliminate in it shows the poor sync issue very well. I would ask specificly if your friend set the butterflies or not, u am willing to bet he didn't and that is the problem.

Much appreciated Nathan, I'll send him an email now!

That does make sense that that is why it is running so poorly. DUH.

Would it be advantages to attempt a sync with the solo unit mentioned before that can be rented from autozone? I don't really understand how they could be synced that way. My assumption is it would still require the eliminator?

[natemoen]

Yes even doing it with a single guage you need the eliminate in (most people leave the eliminate in all the time anyways).

To do the sync you need to first get a reading for the #3 carb, then adjust the #4 to match #3 with the screw between 3 and 4, then double check and adjust again till 3 and 4 are the same. Then you go and do the same with 1 and 2 and get them to match each other with the screw between 1 and 2. Now the screw between 2 and 3 adjust 1 and 2 so you can match them to 3 and 4 so now do the same procedure as before to match the to pairs.

It is a bit more time consuming to do it with a single gauge but still doable.

Ah ok that makes sense. Good to know there is a another available option if I don't have the right adapter for the Motion Pro (it's setup for a newer Honda vtwin).

So sounds like a good cleaning of the passage is in order, then reinstall the eliminator and just do the best to keep it running while we sync?

Of course find out first if the butterflies were evened out, and if not I'll figure out what it takes to do that.

Hi Smash,

First let me point out that even if you clean the passage until there's no oil in there, if you leave the YICS Eliminator installed, it will look like that when it's removed. I have yet to figure out exactly where the oil comes from, some of it is the oil you used to lube the O-rings when installing the tool. As SFer pointed out, some of it comes from the air-box. I also think some of it is from the valve seals. In any case, I have not seen any problems from this and it really doesn't hurt anything.

I recommend that you keep the YICS Eliminator installed.

Nate has given you some good advice on synchronizing the carbs. I would add that as hard as the carbs are to remove, it might be better to pull them and do a proper bench synch on them first. That will get you very close, then it's just some fine tuning.

One other thing before all of this, is make sure that your fuel levels are right. If they are off, so is everything else. On the XJ they must be set with a sight tube to measure the actual fuel level.

Hope this helps,
Larry

The following link will give you a good idea of how to bench synch your carbs.

Thanks Yahman for the additional information. I don't know what you're talking about with the fuel levels. Quick description or point to an area in the manual to educate myself?

Don't have feeler gauges.

Right now feeling utterly discouraged.

[Smash]

We can make our own feeler gauge to balance the butterflies.

[Smash]

Will look through the manual tonight to locate the fuel level check, thanks for bringing that to my attention!

[Yahman]

Page 4-5 & 4-6 in the XJ service manual describes setting the fuel level.

You can use a metal twist tie from a bread bag, just strip the paper off and it will work great to do the bench synch with.

Brilliant thanks Larry. Glad you include extra o-rings with your kit!
