705 updates

Im wondering with the 705 kit ,pipe can and updated cams this boosts the klr to nearly 50 rwhp. That's almost the same as a heavier versys or vstrom at rear. Think those bikes mid 60 flywheel. So with my weight 195 I should be close to a 220 lb rider and the extra weight of other two style bikes. Or is the klr still a little hp handicapped?

A stone stock KLR650 can get you a speeding ticket in any state in the Union. And a 705 cc kit and its attending labor gets pretty involved. Best to stop at 685 cc & reserve the 692 kit just in-case of a screw-up.

A 685 with properly ported head and Degreed camshafts along with air box mods & a a freer flowing exhaust should satisfy your desire for MORE. Mine is more stock than not.

Thanks for post. My nephew is buying the new ktm 790 duke for a long haul to yukon. Although he out weighs me by nearly 30lbs i was hoping to keep his tail light visible. Im used to wrenching on snowmobiles all my life and currently big bored my 2013 summit 800 to a 872.

After reading the smallport article more bore would actually help the big head. I also build cleveland ford engines for a hobby and i will say the flow on these heads even stock is impressive to say the least.

Steve.k, I'll suggest that you take the time to read the rest of klr.chris articles.

And a cross-country tour shouldn't be a race. But yeah, I know some roads just beg to be ridden quickly. But its not how fast one can accelerate out of corners that makes those roads fun with touring gear, its how little one slows down for the curves.

Maybe you ought to consider Cogent Dynamics suspension upgrades to control the touring load, rather than horsepower to accelerate the load?

Yes i know what your saying. Im just saying to make the bikes closer. I read pretty much his whole site. I recently talked to fella who did this yukon run with the 685 kit. He was very happy with the bike. He said it. Ran flawlessly and the extra oomph was great to have. He had A daylong seat on his also.

I put a 685 on mine...I honestly cannot tell the difference vs. the original 650. Well, one difference is I no longer have to add oil every 100 miles. And, I suppose it's a bit smoother. But as far as oomph goes...well, the KLR is not known for oomph. If I want to go fast, I ride a different bike.

A KLR makes, what, 35 horsepower or something? So, you jazz it up, and maybe get 40 horses. Not enough to notice..

Slow and steady wins the race many times.
