tabshee Posted June 27, 2004 Report Share Posted June 27, 2004 After searching many posts it seems that the solution to the problem I'm having is in the Bermuda Triangle. I just bought a 1996 Shee with some nice mods and it ran perfect at the sellers house (wouldn't ya know) I get it home and I am running it around my homemade track and it starts revving to the MOON - i pull the kill switch and roll it back. The setup is 2 into 1 Trinity stage IV with Keihn PKW (spelling is probably wrong) Carb (single carb). Well I check the throttle cable and it isn't kinked. The slide goes up and down like it should and you can here it bottom out (work perfect) - I pulled the carb apart and went through it and it is all clean, put it back together and now it seems to just act crazy - revving up then cutting out and revving back up and cutting out - until I pull the choke then it just screams. My spark plugs were fouled so I thought maybe it's that simple - NOPE new plugs- same thing. No airleaks checked for that, tors removed, parking brake gone. Help, Help, Help Thanks!!!

Oilsmoke Posted June 27, 2004 Report Share Posted June 27, 2004 If you have remove carb and replaced it make sure the cable is seated all the was down to the cap. If it got hung up little it will rev. Quote Link to comment Share on other sites More sharing options...
tabshee Posted June 27, 2004 Author Report Share Posted June 27, 2004 cable is seated - for sure, it's like the carb isn't responding to the slide at all - you have to keep bipping it real fast just to keep it going then it revs up by itself and cuts out - until I pull the choke then it gets stupid, revving through the roof Quote Link to comment Share on other sites More sharing options...

tabshee Posted June 28, 2004 Author Report Share Posted June 28, 2004 This slide can't go in backwards - only one way Quote Link to comment Share on other sites More sharing options...
BanshAholic Posted June 28, 2004 Report Share Posted June 28, 2004 Sure sounds like an air leak to me,have u checked the carb boots,my buddy blew a base gasket on his tri-z and it did exactly what ure explaining. Quote Link to comment Share on other sites More sharing options...
geaux 4 it Posted June 28, 2004 Report Share Posted June 28, 2004 Spray carb cleaner around the reed gaskets & the base gaskets to see if you have an air leak in that area. Quote Link to comment Share on other sites More sharing options...
reas11 Posted June 28, 2004 Report Share Posted June 28, 2004 it's def. a problem with too much air going to the carb havoc was on the right track if they were rs carbs this would be the result of the idle screw being in too far or the slide was in backwards . your problem is def. in the carb u just gotta single it out .

tabshee Posted June 28, 2004 Author Report Share Posted June 28, 2004 reas - now that you mentioned it - I did try to adjust the idle on the carb just before it went haywire - the idle screw is funky - plastic head that was probably stripped the first time anybody tried to turn it - it is also spring loaded - I first turned it into to lift the slide slightly because the idle was real low and thats when I went for my ride and wham thats when it started - so I kept adjusting it out to drop the slide and couldn't get it right. Again it is a funky idle adjustment and I could certainly see how some air could get by it - I'm guessing maybe I should pull it out and re-seat it. What do you guys think. Again the carb is a keihin pwk - have any of you guys messed with them? Thanks Quote Link to comment Share on other sites More sharing options...
reas11 Posted June 28, 2004 Report Share Posted June 28, 2004 theres your problem check to see if its still there when i was out in glamis i lost one of them .. if it was backed out to far it might have vibrated loose .. but theres your problem for sure it's in too far back it out and start over alittle is alot .

Hockey390 Posted June 28, 2004 Report Share Posted June 28, 2004 if that isnt your problem, which it sounds like it should be.. Then take your filter off or whatever you have, and see what the slide is doing, have someone rev it up or whatever you were doing to make it go haywire.. See if the slide is sticking, or if its going down all the way for that matter.. If what reas said isnt it, and your slide moves fine, then your only other option is an air leak somewhere.. my 2 cents. Quote Link to comment Share on other sites More sharing options...
tabshee Posted June 28, 2004 Author Report Share Posted June 28, 2004 The idle screw is still there in fact when I was adjusting - it turned really hard and the fact that the head is plastic didn't help - I was thinking about pulling it out all together and wrapping some teflon around it to see if that might make a difference - if there is air getting in and around it - the teflon should make difference right? I will also check the slide although I can hear it pull up then come back down and hit bottom - I also checked the action with the slide out of the carb. We'll see - I am thinking in some way it has to be the idle screw because it is the only thing I adjusted before it went off like a crack addict. Thanks for the help guys, I'll let you know what happens. If anybody is interested I bought this 96 to sell (I have a 90 that I am keeping) here are the mods: Fresh top end with Wiseco's, FMF Fatty's, Stage IV 2 - 1 with Keihin PWK Carb, Works front suspension (not gas) Race Tech Heart Transplant Rear Shock, Amp link chain tensioner, Brand new Henson Clutch.

tabshee Posted July 1, 2004 Author Report Share Posted July 1, 2004 THIS REALLY SUCKS!!! OK here is what I have done - installed a new NONE PLASTIC idle screw and adjusted it properly, fired it up and same thing - first nothing then I pull the choke and WHAM it hits the roof. I pull off the filter and check out the slide action and it is for sure hitting bottom, so I take the slide apart and find the clip on the lowest setting - so I raise it one, put it back together and same thing - revs crazy on choke. Next I turn the idle screw in enough to make sure it raises the slide and fire it without the choke it Idles high but doesn't get to crazy - so I bip it and it hesitates and then takes off for a second then comes back down to high idle, I turn the idle screw out and drop the idle and it slows down but its rough and when I bip it shee hesitates and takes off again - comes back down and idles rough - I pull the choke and WHAM it goes off. After playing around for about 15 minutes I noticed that the left side is dead flat COLD - not even firing. I don't know why I do this to myself - you have to be into S&M to own one of these things - AND I HAVE HAD 4. I felt like pounding the screwdriver into my eye. In my last post I mentioned interest in selling it - disregard that I wouldn't wish this pain on my worst enemy. PLEASE ....For The Love Of God And Country....... Help.

tabshee Posted July 1, 2004 Author Report Share Posted July 1, 2004 Oh and by the way - Brand Spanking New Spark Plugs - keep in mind single Keihin Carb set up Quote Link to comment Share on other sites More sharing options...
23champ Posted July 1, 2004 Report Share Posted July 1, 2004 Don't know about the dead cylinder, could be a number of things. As for the crazy idle, perhaps the carb has been bored and the slide is not wide enough to seal the airflow. Or the slide could be wore out, thus causing it not seal also. The best way I've found to tell if a slide is wore out is to rub some white lithium grease all over the slide then install it back into the carb, this will help a wore out slide seal. Then fire it up and see if it still does it. Although this is just a test to see if the slide is wore, you wouldnt want to use this method as a fix.
