Double check the throttle again... Sounds like the the cable, or linkage, has gotten hung up on something. The repair you made to the ign advance would have nothing to do with a wide open throttle (WOT) condition. On the other hand, did you remove the airbox from the bike when you installed the aftermarket filters? To do that without destroying it, the carbs must be removed. I'll bet some how that's where the problem lies. The only way to get a WOT is for the throttles to be physically opened. Nothing in the ignition system could cause this. Hope this helps.

Re: Engine Runaway

I wouldn't think that the pick-up wire repair has anything to do with excessive rpms at idle. If you previously adjusted the idle to try compensating for the bad pick-up wire, you might adjust the idle back down.

Make sure that when your throttle position is all the way down, the carb linkages are returning all the way to the stops. I like to have just a tiny bit of slack in the cable when the throttle is off. Also, check for binding of the cable in the sleeve or bad routing of the cable. FYI, I once had a runaway throttle that was due to a broken tab where the metal piece of the sleeve attaches near the handlebars.

One more thing comes to mind. Although I have not installed individual filters, I understand that if you have older model carbs, 78 or 79, the breather hoses can not be plugged, or the engine vacuum will cause the fuel levels to rise dramatically, in some cases it will cause flooding.

Okay this is what is going on.

First I did the vac advance repair. (snip)... I checked the throttle cable and linkage stuff around the carb set for obstructions of which there where none.

I am thinking the repair I made to the vac advance failed and has got the thing stuck wide open. I am going out right now to pull that cover off and check to be sure.

Thanks

I have checked the linkage it doesnt appear to be bound in any way at least no more than before. The guy i bought the bike from had already done some work to the airbox so most of the lines are already capped off.

i will check the final resting position of the links.

I realize a well that the ign advance had nothing to do with the WOT issue I was just running down the list of stuff I had done prior to this issue.

I'll be back in a few.

Thanks

Adjustment

Thanks Skids

I adjusted the idle and it seems to be okay at least a bit better. When I hit the throttle it revs (duhh) but it doenst come right back to idle it sounds like it it slowing down. but it did that before so I am not overly concerned about that.

I had to take the tank back off and check the routing of the cable and stuff. But the adjustment of the idle has helped a great deal. i think I am on the right track now.

The other thing that has appeared it is spitting and spuddering I think that might just be that it is cold. The only line that I had to moved was one vaccum line that was on the carb set that went down to the advance but that was just a reroute. I may have to rejet the carbs again. CRAP... I am going to put her back together and take her out and see what happens... I'll check back later...

Thanks Again

Something New

I found something new after putting the tank back on.

When I release the throttle. it goes almost all the way back to rest but stops just short. I have to push it back the last tiny tiny little bit.

there is slack in the throttle cable in both positions. The only way I have been able to get the linkage to the correct place is to physically move them. The linkage is rust free and paint free. I cleaned the little bit of paint that was on them off when I discoverd this and sprayed them with WD 40 to see if maybe they where sticking on themselves. Any suggestions: throttle cable maybe?

**mitch** · 01-02-2004, 01:43 PM

You answered it yourself

You said (after i put the tank back on ) Would that not suggest the cable is getting possible jammed or pulled under the tank someplace Take it off and see if it works right .............MITCH

Filters

Springer i read on here once when one of the guys put filters on they had trouble cause the slid them on too far and covered up the port on the end of the carb. if u take one off you will see a port on the end of your carb, if you shove your filter all the way in it blocks that port! just a thought HTH..............MITCH

**scalded dog** · 01-02-2004, 04:50 PM

"fixed the advance under the right cover" I hope thats a misnomer, if the throttle dosn't go all the way down you may need to sinc them.

**Springer** · 01-02-2004, 05:54 PM

That is what I get for working and not reading huh..

Okay to catch up.

With the tank off it works perfectly. I will recheck the cable routing tommorow (its dark here)

Yes it was a misnomor. I meant the left cover as sitting on the bike. My brain was off the bike not on it. I'm usually a little off. haha

With the tank off it runs perfectly actually better than it did before imagine that.. that goes back to my above comment.

I will check to make sure that the ports arent covered.

I managed to get the bike out of the shop and moving. It ran like a scalded dog(no offense)

Okay Dinner time. Thanks for everyones input today it helped a Great Deal. What would I have done without this site.

Cheers

John

I'm proud of that name 'scalded dog'. my first xs11, earned me the name in my club, LOL. there is not a cruiser in the club that can touch it. LOL. Later 'Dog

On my 78, I found that I was getting interferrence from one of the boot clamps. Putting pressure on the screw to tighten it pushed the back of the screw against the throttle linkage. It ran fine until I opened the throttle up enough to raise the linkage above the end of the clamp..... allowing the back end of the clamp screw to pop under the linkage just a hair. It was held up to such a small degree that I could not see it until I forced the linkage back down and the idle slowed. From then on I learned to hold the clamps securely in place and well away from the linkage when tightening them.

Multi stage issue

Okay here was the fix.

I found that during the removal of the throttle cable I had put a small bend in the cable. Replaced it. Helped alot.

next I had the same issue that jeff had. One of the clamps to the boots was hitting the middle linkage and stopping it from going back to total rest.

But the good thing is I have had the carbs aparts and cleaned better than I ever have. new cable.

I noticed when I had the carb set off the butterflies where not lined up with each other. I fixed that issue. I guess during all the adjustment I got them out of whack. But they are cool now.

I'm going for a ride before it starts raining it is 62 right now and the high is supposed to be 74 can you believe this for January in Virginia. WOOOOOHOOOOO!!!!!!!!!!!!!!!

Thanks for everyones help...

**mitch** · 01-04-2004, 09:37 AM
