<><><><><><><><> <><><><><><><><> Luc, I don't think I have enough information about how or where you ride to give an opinion about slide drilling. I can tell you that I haven't done it to mine. Mine has some mods, I guess others have to be the judge if they are major or not. I suppose the trade off for fuel economy that folks talk about would be enough to put me off on it. I'd also guess that unless a guy was an 8 or 9 tenths rider it wouldn't make much of a difference. I'm still using the original stock brake pads at 23,000 plus miles. Maybe the folks that wear out a set of front pads in 5,000 miles would find it useful. I think you can get a diaphragm and slide at the Harley dealer for about $50. So it might not be a real expensive mod and it surely would be reversible.

TPI has 'em for $39. It's reversable anyway, you can just fill the hole with JB Weld and redrill it to the stock size. Michael -- "It ain't those parts of the Bible that I can't understand that bother me, it is the parts that I do understand." -- Mark Twain San Francisco, CA

Drilling the carburetor slide vacuum port (not the hole for the main jet needle) works best when you also use a lighter slide spring such as the one supplied in a DynoJet kit. You may, however, contact DynoJet and order the spring separately if you haven't already purchased a complete kit. Drilling the vacuum port to 7/64" (1/8" for larger motors with more vacuum) will generally improve throttle response but will NOT measurably reduce your fuel economy -- your right wrist has a greater impact on fuel economy than a relatively minor modification such as a drilled vacuum slide. Drill your slide (either 7/64" or 1/8" is okay), install a lighter slide spring if you wish, and open up the air fuel mixture needle by 1/2 to 1 turn. Your bike will run much better. ________________________________________ PeoplePC Online A better way to Internet http://www.peoplepc.com

<><><><><><><><><><> <><><><><><><><><><> TC, Your last sentence has my interest. Could you be a bit more specific as to the definition of "run much better"? An example or two might be helpful for me to understand the benefits of drilling a slide. I suppose having a little more pep when accelerating would give some folks the nudge to twist the wrist a bit more in other riding conditions too. Maybe that's where the fuel economy drops show up. I'm sure if you open a properly tuned air fuel mixture screw (by your 1/2 to 1 turn) that will drop fuel economy.

Jeff, I drilled the slide out to 1/8" on my '95. What it took care of for me was a slight lag at lower rpms when you twisted the throttle. I can't tell any difference with the middle and upper rpms. Most of my riding is off road. I'd run into places that you needed to power lighten,(on most dirt bikes it would be a wheelie), the front end to help over a small tree or rocks. With the KLR in stock form, it would take a fraction of a second after twisting the throttle for the engine to start powering up. After the mod, there's no noticeable lag, so you don't have to preplan as much. The only mods that I've done is increased the pilot screw to about 1 3/4 turns and the slide mod. I've also changed the gearing to 15/47 for off-road and use 16/47 for extended on-road riding. I can't tell any difference in MPG, 45-52, unless I'm in twisties and really on/off the throttle quite a bit. I don't know if that is due to the idle mixture adjustment or the slide drilling, since both were done at the same time.

<><><><><><><><><><><> <><><><><><><><><><><> Greg, Thanks for another very good explanation. First it was a tire evaluation and now it's performance based on an internal carb modification. You're on a roll. : ) It sure looks like you scored well with drilling the slide. I'm running a 14/46 combo in the dirt. Your 15/47 is about mid-point between my 14/46 and 15/46 combos. Looks like it would be pretty comparable to a 14/44 combo. I know it's a significant improvement compared to the stock 15/43 combo. I bet you'd really like a 14/47 combo in the dirt. It might be a bit slow in twisties. I sure appreciate your detailed and complete comments.

Jeff, I have the 14/47 combo also. You're right, it's great in the tight stuff. I'd even considered the 13/47, but couldn't locate one for the two bolt earlier models. I use it when it's a weekend of mostly off road riding. When I have to run short commutes, less than 150 miles, I'll just run the 15/47 as an all around. Longer runs, 4 -500 miles, I go to the 16/47.

Hi Jeff, wish I could take credit for the slide write up but it comes from a different Greg, Think I might add the slide mod to mine while it's apart though...have a great evening....the "tired" after busy weekend Greg Jeff Saline wrote: On Sun, 24 Feb 2008 08:53:48 -0800 (PST) GMac999 writes:
