KLR exhaust?

[tashunka]

Anyone here running an aftermarket exhaust on their KLR650?

If so, what are you running and what carb changes did you make, if any, to accomadate the new exhaust and what changes did you notice in performance, if any!?!?

Cool, thanks Duall!



I just took a quick look at the Big Gun Exhaust website. Which model do you have the 'X'? As far as I can tell, it's the only model they have a KLR Specific version for. They say in their blurb that jetting is required and the exhaust will add 3 HP. Not huge power, but it's something.Don't knowif the $300+ USD plus shipping etc is worth it for only 3 horsepower though......

Hay, I've got the full Big Gun system, up 1 on the main and a spacer put under the needle, punched 4 x 1" holes in the top of the airbox, and the difference is large over stock, crack it in 1st and it'll go over if you're not careful, that's a huge change over stock.

have you noticed much of a change in fuel mileage, 04?

probably, but it's hard to tell when it's always whacked open! yeah it's down a little but seriously I'm not too concerned with mileage, it is what it is, and I'm ok with that given the power gains. If a real adventure is happening (like my Inuvik trip last year) carring fuel is smart anyhow, (though I put the stock pipe on, quieter and no packing issues)and for all else the range is only down approx. 20k per tankful, a non event to me, as my buddy Greg would say, GIVERRRRR!

Hey guys, i just put on a IDS2 Supertrapp and a stage 1 jet kit , along with a twinair filter. It has given more bottom and midrange and smoothed the motor a little.

Hi Tashunka, managed to install a Supertrapp & center pipe kit. Terrible fit, had to rethink most of the hardware. Bike lost at least 4kgs, nice because the HEAVY stock muffler was so far from the center of the bike. Already had a K&N airbox filter in there. Wound up with 4 sizes over stock on the main, needle up 2 notches, still thinking about air screw. 1 turn more than stock seems close. Adjust your valves to the tight side, this gives more lift and is easier on the valve train as well. Bike runs WAY better everywhere and is a bit faster. Fuel range is still great if you cruse and a bit worse if you flog it. If you`re feeling rich forget this pipe and try the Hindle full system. The Supertrapp should be considered a cheap alternative. Sure sounds good though. Bye. Leon:tup:
