No.......... Bogdan [Non-text portions of this message have been removed]

I have a 2007 klr 650-supertrap and jet kit and twin air filter--bone stock my mileage was 49-51 as an average---with above mods it is 53- 55 and more if I ride steady--I have hit 59 mpg before. But it depends on alot of factors---BUT, weigh the stock exhaust to the supertrap and look at the weight difference, it is alot, horsepower to weight is a factor also. My 2 cents. Oh by the way, there is also a performance boost. --- In DSN_KLR650@yahoogroups.com, "hardyreels" wrote:

I haven't done so on the KLR (yet), but have added pipes and/or jets on just about everything else I've had. In general, it does increase mileage AND/OR performance. The reason I put the "and/or" in there is because if you get more performance and use it, you won't get better mileage. If you want better mileage, don't use the additional performance. Most riders (myself included) will use the performance if it's there, so don't plan on getting better mileage.

Why private? Others may get some value from the answers. Also, it seems kinda silly to join a mailing list if you don't want to actually read the list replies. --Jonathan "smthng" Kalmes Springfield, VA 2005 Yamaha FJR1300ABS - "Blue Bayou" 2006 Jeep Unlimited Rubicon - "Teflon" 2008 Kawasaki KLR 650 - It's here, but it hasn't earned a name yet. http://smthng.info "If I'd known it was harmless, I would have killed it myself."

My prediction: there will be a lot of different answers to this question. This is the one you can take to the bank.

With all due respect to after-market vendors....where are the independent, 3rd-party studies indicating significant performance gains (in power or mileage)? In fact, I don't see manufacturers pimping improved mileage any more than they can support it with scientific proof. Sure, there are tons of anecdotal stories including ones resulting in detrimental effects: where carb, pipe and airbox mods actually reduce performance. I think many people install these things, rejet, etc. and then proceed to convince themselves the change made some huge difference. Mentally, if this pleases you by all means get out the check book. I suspect there is some change but good/bad and measureable? you need to prove with something other than a "feeling." I mean we're not talking myth busters here in this forum. And by the time you factor in $400 for parts (we'll exclude time, tinkering, repacking, dialing- in...all the wasted time fiddling), that's roughly 100 gals of gas or 5,000 miles. I'd rather spend the $400 on gas, personally. My opinion is if and when someone buys a pipe and supports their assertions with "real" scientific data under controlled conditions (measured fuel, dyno or same road route, similar conditions in temp/humidity, etc.), then I'd put some credence on such claims/results. Until then, still I claim my stock KLR gets 500 smiles per gallon running on standard petrol plus adding a special fermented spider urine which coincidentally I sell for $1,000/oz on my...ah...spider-website. --- In DSN_KLR650@yahoogroups.com, "hardyreels" wrote:
