I need more power for my KLR 650...any ideas??
repost this in thumpers.
Try the search function - especially in "KLR Stories". There have been numerous posts about this . . . . . with (if I understood those with more knowledge than I correctly) the consensus being that it's really not worth it. You can get roughly an additional 3hp but lose 30% of your MPG. Advice? Learn to love it they way it is or buy a KTM640. Sorry.
Get something else.
From what I've heard about KLRs...I can tell you that the KLR is not a bike that benefits from power "upgrades." I think the above advice is pretty right on-- live with what you got, or buy a different bike.
There maybe airbox mods and jetting mods, but beyond that, I would say that it's not worth your effort.
How about trading it for a honda XR L 650, I think that it will have a power advantage, but those things are tall as hell. I don't really know as I don't own either, but every time I read about the honda, sounds like people can't keep their front wheel down on that thing.
You can't really get more power but you can easily change where your power band is located. I wasn't interested in riding fast so I changed the sprockets for more low end torc. The counter shaft sprocket (front sprocket) is 15 tooth stock and I changed mine to a 13 and the rear is 43 or 45 stock (I can't remember) and I went 2 teeth bigger to 45 or 47. The biggest difference was definately the counter shaft sprocket. I barely noticed a difference with the rear sprocket. The power band was right where I needed it for riding trails and climbing hills. I probably ride 90% off road. So I put up with that for 2 years and then a few months ago bought this.
I don't mean to be a smartass, but why 3 threads on this same question?
Also, if you tell us what you want the more power for, we might be able to help - do you need more low end climbing power or high end speed? Are you riding 2-up, hauling a trailer, hack? Generally with the KLR, power isn't the issue, but suspension, braking and comfort are. I'll agree with the previous posts that those of us that ride the KLR either have all the power we need or get a different bike.
well first time posting threads at advrider..did not know exactly how it works or where to put it!!!!...anyways I live in Quito at 2800 meters above sea level...tha is why I need some more power sometimes..
What's that, about 935 feet? I live at 7,200' above sea level, which means I'm realizing about a 25% loss in power on my KLR650. And that's before I head up into the mountains - typically riding between 9,000 and 12,000 feet altitude. I've never had the bike fail to climb any hill or accelerate in a lively fashion. I'm thinking that the bike would be wonderful at sea level - same power with lower rpm level to make it happen. I fear you won't get much more out of your bike than stock hp - but it can be rejetted for your altitude and that may help some, as should opening up the air box and keeping your air filter clean and oiled.
More like 8600 feet. He needs a rejet. Mine gets a little weak at altitude, also. Not so bad at 8600 but worse the higher I go. It won't ever be like sea level, but it can be improved.
Damn you are way up there ain't ya. OK you need smaller main and probably a smaller pilot jet too. I'd drop down to a 13 tooth countershaft if it was my bike. I ride a DRZ E for the dirt they come with 14-47 gearing. I ride to high mountain lakes and run 13-50. It doesn't have 70mph anymore but the damn thing will climb a telephone pole if I could hang on to it. oldasirt
Lose 40 lbs.
I regularly do a 700mi round trip to my wifes family farm,the ride goes up high in the mountains,then back down,It might sound crazy,but my bike actually runs better at altitude,I notice it pulls a little harder,and feels crisper on throttle response,Is this even possible? Im not jokeing.I can feel it.Right now,Im running E-Mikes recommended jetting.slip on LEXX,opened up airbox,22 cents mod,uni air,95 oct.fuel.stock gearing,with Pirelli 606s rubber.
Different bike is what you need.
I just got another bike, but if you can't do that then as others have said I would try and jet the bike properly for your altitude. Also there is the 685 kit and maybe a 700cc+ kit. You would have to get the cylinder rebored. I installed the 685 kit on my 08 KLR and it did not add much power but the engine ran smoother and did not burn oil.
It's been 6 1/2 years since he posted. Hopefully he figured it out.
It sounds like your carbing is a bit lean for where you normally ride, then altitude richens it up to run correctly.
I have a 06 that I put a 705 piton and ported and polished the head. I left the stock valves and modified the carb, kln needle and jetting. Nice overall improvement in torque. Less Vibration with a much lighter piston. I am able to run the bike with a 16 tooth front sprocket and hold higher speeds more comfortably. www.mtechmotorcycles.com is one place you could use. I have talked with these guys and they seem to be competent. I purchased mine through schnitz racing and used a local machine shop. I love the bike, and have been riding the 705 for 3 years.
My 2006 KLR650 was stolen last Tuesday night.
It had a 688 bore kit, stage II head and FCR-MX39 carb. It pulled WAY better than stock and the power band seemed to never end.
