Cool Ways to Increase Power on the KLR 650

I would like to squeeze 20 (yes 20!) more hp out of my KLR. Have any of you experimented with ways to get more power of your KLR? I read that a performance exhaust isn't worth it. Yes, there is the 685 and 705 conversion. How much do they yield? Turbocharging, anyone? What are the most reliable methods? Thanks. DesertRat

KTM. Costs the same as a futile attempt to get 20hp out of the KLR and you get a real bike in the bargain.

Start by starting with a different bike.

You'll get significantly more power and you'll save a LOT of money as well.

Generating a lot of power is just not one of the KLR's strong points.

The KTM690 delivers around 70 engine brake horsepower; the manufacturer claims 305 pounds dry weight.

Out-of-the-box, I imagine the KTM beats the, "World's Fastest KLR," run at the Texas Mile and at Bonneville. I'm close-to-certain the KTM will win a drag race with ANY KLR.

The, "World's Fastest KLR," has EVERY hop-up option applied, sparing no expense. Getting another 20 HP out of a basic, "sow's ear," comprises a hard row to hoe, IMHO; YMMV! And . . . the WFKLR can be ridden legally ONLY on a closed course.

What they said. you can get 2-3 hp with a jet kit, airbox mods and a decent silencer....perhaps a hair more. The 685 will give you another 3 or so.....after that it's cams, porting, etc. which may net you a total output in the 45hp range. 20? ...maybe with Eaglemikes 719 kit and every mod and trick in the book but I doubt it. The best advice is the advice you've already recieved; the smartest, easiest and cheapest way to have a 50-60 hp dual purpose bike is to buy a used KTM690R.

yes, as Damocles mentioned, you could try turbocharging and nitrous as this guy did: OSRT - World's Fastest KLR 650 ....but at the end of the day, to get there you ruin what is good about a KLR by trying to make it into something it is not.

2 cents,
Dave

this is dated and people have gotten a bit more out of their KLR's with the right mods but it should give you an idea on what you can expect when modifying a KLR engine; Patman's Kawasaki KLR650 KLR 650 Dyno Results

DesertRat,
There is some newer tuning information over at this site. But you are really wishing for more than any KLR650 will ever deliver.

I rode my neighbor's KTM 500EXC the other day.

That is a bike I could hurt myself on.

And the KTM 500EXC would be a torture rack to attempt to ride on a true Dual-Sport tour, of say over 1000 miles.

Oh, heck, Paul. I don't think I could ride the damn thing 50 miles!

I've no idea if they even make racks for luggage for those things.
