Capone Posted April 24, 2005 Report Posted April 24, 2005 Anyone got pics of where the idle screw goes? I just want to make sure, this kit is used and doesn't come with directions . Any helpful tips would be appreciated... Quote
Banshee~ Posted April 24, 2005 Report Posted April 24, 2005 I think all you have to do is drill and tap it. Heres a pic Quote
RBD Posted April 24, 2005 Report Posted April 24, 2005 LOL Interesting to see the right carb cap retainer clamp on the left carb Quote
broke Posted April 24, 2005 Report Posted April 24, 2005 You do just drill and tap it, but do not drill and tap where that pencil is pointing. Here are a couple pictures of where I installed mine. It really is a "No Brainer" when you know where to drill. Quote

slowpokebanshee Posted April 24, 2005 Report Posted April 24, 2005 don't forget to grind the idle screw boss on the carb, or the idle screw, will not reach the slide to lift it. I believe Toomey has a "how-to" on their web site, don't be afraid to grind those carbs, I remember taking off quite a bit of material, before I could get the screws to lift the slides... Quote
Capone Posted April 24, 2005 Author Report Posted April 24, 2005 I just realized, I also need a size of the drill bit, and the # of the tap, if anyone can get this... I'd appreciate, or if you have both, and don't need anymore please send.. I bought a twist throttle of ebay, comes with carb caps, but no screws, drill or tap. so I bought screws for 10$ they want 35$ for the kit with a drill bit & tap. I have a full tap set, and I figured I could save the $25 for a drill bit. Quote
RBD Posted April 24, 2005 Report Posted April 24, 2005 You will need a 6 X .75 mm tap and a 5.25 mm (.2067") drill bit. Quote

wesw Posted April 25, 2005 Report Posted April 25, 2005 make sure to file like 1/8 off or more so the screw will hit the slide. just dont file it flat, it wont idle with the nuts on. pretty easy take your time with the tap Quote
dajogejr Posted April 25, 2005 Report Posted April 25, 2005 I was going to have my roommate do this for me, since he works in a machine shop. Drill press, etc. Really...you can do this on a bench... The hole is already there, and you're not taking out much metal. I STRONGLY advise you to take the whole carb apart, bowls off...jets out, etc. Once done, take a good 200 grit wetsand paper, and smooth any rough edges on the venturi side of the new hole. As said...file down about 1/8 inch off the outside, so da nutz fit flat. Since the carbs are soft Alumniminum....I used a scotch brite pad on an angle die grinder...and took my time. ONce done...I slowly turned in each screw till it just made contact. Then...from contact...I turned each one in about 1 1/2 turns. Mine idles just perfect! Remember to warm 'er up first before attempt to adjust the idle.... about 1400 to 1600 RPM is right. Quote
boonman Posted April 25, 2005 Report Posted April 25, 2005 Do not be afraid to hog material off the side of them carbs. You almost cannot remove too much material. Otherwise, your bike won't idle, and you will have to go piss INTO the wind... Quote
dajogejr Posted April 26, 2005 Report Posted April 26, 2005 Yeah....you can make them flush...if you wanted to...to the carb bodies. I've got about 1/8 to 1/4 inch of thread left. Luckily...I set mine at 1.5 turns in...and it's idled perfectly every since....cold or warm. Quote
jaysea1 Posted April 26, 2005 Report Posted April 26, 2005 Just as everyone is telling you...the idle screw bosses(where you will drill)are located on the outside of each carb(left side on left carb, right side on right carb) a drill press with carb chucked up or supported would be best. Take your time, use lots of cutting oil while you are tapping. Also file the bosses down past flat as previously stated, Toomey does have detailed instructions on their site...toomey.com. LOok under the tech documents menu, and it is listed in the "motion pro thumb throttle kit" Also after drilling make sure to de-burr inside of the carbs where the hole exits, so the slides will not stick.

dajogejr Posted April 26, 2005 Report Posted April 26, 2005 Good point indeed. When using the Tap...use a ton of cutting oil or WD40. After drilling...I'd put the tap in 1 to 2 turns...oil her, turn her out. Remember, if you've never used a tap before....always turn it in, then back it out just a hair furter than you turned it in. That'll keep the threads cleaned.... Really...once the carbs are off the bike and dissasembled...it'll take about 1/2 hour to 1 hour. Sure you could knock it out in 10 minutes...but, what would be the point? I would file down the boss After you drill and tap the hole. That way...you have more of a "Guide" to drill and tap. Quote
