mods vs. mpg.

[Eddie]

09' KLR650 OEM gearing with a Scottoiler lubing things. Avon Gripster tires @ 30# each {I ride 99% highway miles) Stock pipe with "tweety" core removed and a replacement sport bike muffler tip riveted in place shimmed needle drilled slide air screw back out approximately 1.75 turns ( most of my riding is below 1,300 feet above sea level.) OEM air filter replaced with a Uni two stage foam filter. 190# rider riding the bike "spiritedly." lol ...................... MPG consistently in the low 50s eddie

From: eddie transalp1@... If you put the stock muffler back on, the bike may be a little rich and a stock main jet would be in order. They tend to be lean from the factory, anyhow. As for the drilled slide, there's an air hole that allows the slide to rise/fall easier. Enlarging it can aid throttle response. I drilled the slide, shimmed the needle and backed out the air mixture screw a little on my otherwise stock 09'. It's run terrific for 17,000 miles since I did. If I were in your position, I'd put the OEM muffler back on and see how the bike runs 1st. It may "like" the setup. =) eddie [Non-text portions of this message have been removed]

If you think oil threads are confusing, try reading this on 'water' threads about coolants. http://www.fordmuscleforums.com/all-ford-techboard/461928-anti-freeze-straight-water-better.html they do make a good point about straight water; it contains no water pump lubricants--though I am not so sure we need it in the KLR in the same way an automobile needs lubricant for its water pump. revmaaatin.
