I dont have a supertrap. I think it depends on how many disks you put on it and how much it free flows. If you have not done it already, you need to open up the pilot mixture screw. that shouldnt hurt your milage.

Your question - or something close - comes up regularly on this list, John. The consensus is that it's not worth doing. Use your mod money for suspension upgrades. Yes, you'll gain little in power and compromise your gas mileage. The quality is often not great and you'll need to repack the can. I personally don't think the weight saving is significant on a bike like the klr. FWIW my experience is that if you install all the discs you don't need to re-jet however the bike will run a tad lean. I would be best to shim the needle a bit. Anyway, my SuperCrap/SupperTripe now sits on the shelf. Bogdan

About a month or two ago, you said that adjusting your pilot screw "would" effect your milage, which it will. Doing anything to change the mixture richer will effect the mileage. Even the slightest little adjustment. I have been into my carb dozens of times now, to rejet for an aftermarket pipe, and then again to rejet for the stock can. Each time I go in I make one tiny adjustment and then check everything. Mileage, idle speed, cruising, top end, blah blah blah. Mileage is the one thing that will always change with the adjustments. I have also adjusted quite a few other bikes. Some stock ones a bit richer for a little better response and cooler running, and some other ones that have been adjusted so rich that they are down right ridiculous. It is VERY easy to jet the KLR too rich. The window for a finely tuned carb is very small. MrMoose A8 (Barbie and Ken special)

If you are looking for a bit more performance, as some folks have said you are better off spending the money on suspension upgrades, that will be your best bang for the buck. having said that, like CA Stu recently rediscovered, an aftermarket pipe does offer better pull off the low end so it does help. I converted to the Dynajet kit at the same time I added a pipe and found the Dynajet recommendations were spot on with the addition of the pipe.

Even CA Stu is not immune to the placebo effect. He also has been known to be manipulated by women who likewise pull his low end. Bogdan

If I did then I hust have forgot to hit the "not" key on my key board. The first carb mod I did was drill out the pilot screw cover and richen it up. At that time I didn't drill out the slide or put larger main jets in. after riding around with just the pilot mod, I noticed no increase in fuel consumtion. there could have been 1/2 mile less but I dont pay attention to what on the right of the decimal when calculating miles per gallon. drilling out the slide reduced milage by 3 MPG. putting in 155 (???) mains, knocked it down to almost 40 MPG

Geeeeesh what a pushover.... get a foot massage and gets stomped on.... Placebo effect.. hummm Cobra can gave me more low end grunt, at least it seemed like it, but the NOISE was horrible... packed that little sucker with just about anything non-flammable I could find... Fiberglass insulation, Stainless Steel Wool... did'nt matter it was LOUD !! On the road is was bearable with ear plugs, but in the tight woods... my my the echo was enough to take out fillings. My opinion... keep the OEM can, de-tweety it when the time comes and adjust the pilot circuit to the sweet spot right now, still need to drill my slide, but will get there sooner or later.

I can confirm more low-end grunt with the supertrapp. I found I REALLY liked the power for tight woods riding. Unfortunately one good dent in an IDS2 canister and it's rendered un-repackable. And "quiet core" is a relative thing, I hated the noise it made, even through earplugs on the highway. In the woods it was annoying after a while. The stock pipe is quiet, indestructable, and gives a nice easy power that makes the bike hook up real well in slippery stuff. Spend your money on suspension. The bike will be more fun to ride with better suspension. Devon
