<><><><><><><> <><><><><><><> Jamie, Doesn't sound to me like you are really wanting a performance increase or to change the bike much. It is after all a KLR and you'll never get significant performance increases from any individual mods. Unless you have a particular issue you want to address I don't see any point in putting on an aftermarket exhaust. That almost $200 is a lot of smiles when it's converted to fuel. : ) I'm gonna guess if you try to sell it at best you might only get $150 for it. So if the company will take it back, even with a 20% restocking fee, you might be better off in your wallet. Just for grins if you only get $150 for it and fuel is $4 a gallon that might be worth about 1,875 miles of fuel at 50 mpg. I haven't done carb mods on my KLR and it runs well. It starts easily, runs out good and has plenty of power. You might want to consider only turning out the idle mixture screw to maybe 1/4 turn more than it is now and seeing how that affects the stumble off idle and popping on decel. I think the blanket statement of 2.5 turns out is bogus as each engine needs to be tuned for it's characteristics and operating conditions. I did do a 685 kit but that was to address an oil use issue. The real benefit I see from the 685 is a smoother running engine and no oil use. (Turns out the ring gaps were aligned on the 650 piston so I know why it was using oil.) If you are concerned about resale even a little bit I think for most folks the stock exhaust is a selling point compared to aftermarket. There are lots of guys that install aftermarket exhausts but they suggest to me the bike might have been ridden hard. If I was buying a used bike and it had an aftermarket exhaust on it I'd take about $100 off the price of the bike. That's about what I figure it would cost to put a stock exhaust back on. I'll suggest the best place to put money in a KLR is suspension and the fuel tank. For some, brakes are high on the list too but I have over 30,000 smiles on my KLR with the original pads and can still lock up either end if I'm dumb enough to apply them too much.
