FireHead Posted January 17, 2007 Report Share Posted January 17, 2007 I recently got ahold of some stock carbs that had aftermarket caps on them, but did not have the idle screws installed. After doing some searching, I found a couple forum posts and eBay auctions where people had not installed the screws and claimed their bike was running fine. My question is: Do you have to install the idle screws? If you do, what is the tap size you need for them? (I could figure that out myself, but it's easier to ask).

All the idel screw does is keeps the slide from bottoming out in the carb. The screw is like a false bottom and you can adjust the heigth of the slide with the screw to make adjust the amount of air entering the carb..If you order the screws it will come with the correct tap.

Let me add some addtitional informatio to this: I already have a set of screws from a set of carbs that cracked. (A)I was wondering what the tap size was? (B)I know what the throttle screws do, I just wasn't sure if I needed them since folks seem to be running around without them. ©This setup is just something to get by until my triple is done. :thumbsup: Quote Link to comment Share on other sites More sharing options...
Handyman Posted January 18, 2007 Report Share Posted January 18, 2007 Yeah I completely misunderstood your first post :shoothead: , Sorry I had just woke up. Not sure what the correct tap size is...As far as running without the screws...I have no idea. Haven't heard of anyone running with out them.

FireHead Posted January 18, 2007 Author Report Share Posted January 18, 2007 m6 by .75 That answers part of my question. Now I just need someone to answer the most important part. Will they run fin without installing the idle screws? I mean if you just unplug your TORS, your bike works properly doesn't it? Quote Link to comment Share on other sites More sharing options...

Unplugging the TORS only disables it, you still have the idle adjustment on top of the TORS crap that's on top of the carbs. I don't really see how it'd idle good w/o the screw in but I guess some people get lucky. Quote Link to comment Share on other sites More sharing options...

Will they run fin without installing the idle screws? I mean if you just unplug your TORS, your bike works properly doesn't it? I would think that it would run (& idol if you adj your cable enough, if that is possible?) or you keep your thumb on the throttle all the time? :thumbsup: Quote Link to comment Share on other sites More sharing options...
fastrthnu Posted January 18, 2007 Report Share Posted January 18, 2007 I would think that it would run (& idol if you adj your cable enough, if that is possible?) or you keep your thumb on the throttle all the time? :thumbsup: troo,. after I did mine i found there was still enough adjustment that I could have just pulled the cable up farther with the adjustment screw on the cap to open the slides,. but if the cable ever stretches..... with srews theyll never move.

FireHead Posted January 18, 2007 Author Report Share Posted January 18, 2007 That all makes sense. It looks like I will be drilling and tapping some holes, all the while wondering what the people who do not do this were thinking when they installed a kit like this without the idol screws. I think the key piece if information I was missing was that there was an idle adjustment on the TORS. I never had them on any of my bikes, so I really don't know much about them. :ninja: Quote Link to comment Share on other sites More sharing options...

I had to order them from toomey. So alot of people might have assumed that they didnt need em if they got a kit without screws. Quote Link to comment Share on other sites More sharing options...

I was looking at eBay and it seems that alot of the carbs for sale that have the TORS elimination kit installed do not have idle screws installed in them. It makes you wonder if all of these folks are riding around with bikes that don't idle properly. Quote Link to comment Share on other sites More sharing options...
trex banshee Posted January 25, 2007 Report Share Posted January 25, 2007 I have seen them run with and without the idle screws. They are intended to run with them, otherwise if you just adjust your idle with the screw on the top of your carb top you are taking all the slack out of your cable and when you do that it is possible that when you turn your bike to the right as far as it will go it will cause the bike to rev up. (not good) So yes Firehead it will run properly and you can adjust the idle without the screws but not the correct way and not the safe way. Oh also Firehead if you haven't done the idle screw installment before you are gonna have to sand your carb body down some so the jam nut on the idle screw will sit against the carb flat. The carbs from stock have an agled face and all you have to do is make it flat. From your previous posts on here I know you shouldn't have a problem with this, I was just giving you the heads up if you didn't already know.

nunyabinness Posted January 25, 2007 Report Share Posted January 25, 2007 okay i have a question... i have a set of carbs that have the idle screws in them but i have no caps and i don't think i have the cable. i have a ton of the TORS tops with the cables attached. i think i even have one set where the tors boxes where taken off the cables (not exactly sure). my questions are this: can i just get the caps and use the stock cable minus the tors boxes? or do i have to buy a new cable?
