Dunt, dunt, dunt. Another YICS bites the dust...

[Lucky]

My bike been acting sick the last week or so, & i've only had time to look at it today.

Symptoms:
if extra current was used (high beams, turn signals, etc) the idle would drop, bike felt like it was cuting out, & she'd stall.  under acceleration from a stop it'd miss horribly & i'd have to throttle thru it.  running with the choke partially on helped a lot, but i still had to turn the lights off at a stop. engine tempurature made no difference.

so was it ignition or fuel?... hmmmm.

turns out the YICS was blown out. I ride this bike hard every day back & fourth to work, often accelerating to 70+ so i'm not surprised..
I took the one Dave sealed for me off Cafe & all is right with the world again.

Oh Daaaaave! I have a small project for you!!  ;D

It's truly amazing what things the YICS can screw with.  Glad you found the problem.   8)

Amazing what an extra lean condition can bring on. 

Glad you found it, and it was an easy fix.

70mph!?
Damn dude, the speedo stops at 85 :O:O:O

[Lucky]

mine goes to 140 mph...   ;D

[h2olawyer]

Inane - seems to me you have a 140MPH speedo, too.   ;D

Meh, I've never let speedo limits determine mine. :D Governors on the other hand suck boulders...

I carry 2 vacuum caps with me at all times. So if the YICS craps out...I can cap it off at the heads. Then fix it later.

I took my YICS off and never looked back.

YICS makes a difference in running of the '82 and to a lesser extent the '83s. Find one or send me yours. I can fix it.

Oddly enough, I noticed no difference.  After fixing it only to have to reseal it again 8 months later, I finally decided i'd had enough.  I blocked the ports and noticed no difference in how it runs.

The bluish white smoke coming out of your front exhaust pipe as you drove away yesterday was an ominous sign.....

Well, your road was skeeter free for a while!    ;D

I of course tested my YICS out as part of my preparation for my ride later this week,  I see if I can get it to stick to my tongue, I can create a good vacuum but there isn't quite enough surface area in relation to the weight of the YICS box to get it to hang off my tongue (needless to say my box still works at this time).

I have to admit guys, my YICS pissed me off so bad I simply plugged it. Tied the intakes together with some nice clamped rubber line.

Last time I'll ever complain about YICS.

[h2olawyer]

I hope you didn't hook the YICS connections together without something to plug off the hose.  Each cylinder needs to be plugged separately.

I notice some difference between properly functioning YiCS and not having it installed.  Mine runs a little smoother & feels a little stronger at the low end with it than without.  Just a seat of pants feel thing - nothing actually measured to prove or disprove its utility.

[h2olawyer]

Hope your & especially Kenny's days go better starting now.  Glad he's home anyway.  At least the compression tested good.
