Interesting Ride Today

Riding farther afield now and wanting dirt/gravel road experience, so today I headed about 30 miles south on Hwy 90 to Gold Gulch Road and turned onto it. I wanted to go to Jack's Peak, about 15 or 20 miles in and hike to Burro Mtn summit. Ha.

I'd forgotten about the long run of loose sand where the road meanders back and forth down a long, huge dry wash. That 2" extra leg reach the Seat Concepts kit gave me saved my bacon many, many times today in that awful stuff.....altogether a little more than 4 miles of it, before heading up the mountain on a whole 'nuther type of bad road.

I didn't "quite" lay it down but came very close umpteen times. After about 75 total miles today, my butt was keeping pretty quiet back there. Seems to like that new seat just fine. On the stock seat, I'd be in misery by 50 miles.

You've seen documentaries of the Jesus Christ lizard (google it) that runs on water by windmilling it's back legs fast enuf to stay on top ?? That must be about what ol' Lar looked like going thru that loose sand. Bike did its durndest to squirm out from under me - at 5 - 10 mph and me booting it upright about every other second. (I'm only exaggerating a little) Tiresome. Is there any special technique to help in that stuff ??

Also based on today, I'm going to put 1" lowering links on it (and lower the front to match) and not sure which brand is best. One of the mfr's webpages talks darkly about "someone's" aluminum links being prone to breakage. Any idea which one ?? Any preferences ?? I'm too damned old to go cartwheeling down the highway at 70 mph. (yah, I'll be officially 70 yrs old at midnight tonight. How did that happen to wonderful, immortal me ?? )

I'm aware that many don't like lowering the KLR because of dragging pegs, etc., etc. I'm not even a little bit interested in roaring down rocky trails or jumping logs or going around 30 mph curves at 70 mph. I want my feet to plant solidly when I need it.

In addition, I'm thinking seriously about the Top Gun rear spring upgrade - the 6.6 kg version. Has anyone had experience with their Chain Master ?? A goodie or not necessary ??



The picture shows a good spot where I was able to park for a minute and you can see where the tires were sliding around as I stopped.

I noticed that the power band on the bike seemed to go flat around 4500 to 5500 rpm. Still held 70 mph on the hills but didn't feel like it was really interested.

Thinking on that, the muffler mod really did make a difference. Now I'm thinking about the air box mod. ("L" mod ??)

I've read a lot and thought a lot about the JD kit and think I'll order one tomorrow. Also, I read somewhere about an idle "mixture" screw to replace the stock one under the little aluminum cover so that you can tune idle more easily. Turn it with your fingers. Mixture, not speed. Don't remember where I read it, but haven't seen anything about it on this forum. Is it a good thing or no ??

I'm having a bit of trouble with that sight gauge for engine oil level. (I "much" prefer a dipstick so I can see just what I've got) It looked low this morning, so added oil....just a bit, like 5 or 6 ounces and now it looks over full. What am I not doing right ??

Has anyone had any experience with the 02 sensor air/fuel mixture gauges ?? Seems like it'd be a good tool for fine tuning mixtures and not all that spendy. I like the looks of the Equus brand.

Can't remember where I read or saw it, (old age, again) but someone, I think on this forum, made a "cruise control" out of a length of vacuum tube and just jammed it between twist grip and front brake assembly. It worked like a charm for me last week and this week didn't want to stay put. I'm tempted to spray a bit of silicone lube on it, but not sure how that will affect it. Any thoughts out there ??

Sorry for the long, long post, but thanks in advance for any help............Lar.

Lar - the JD Jetting kit comes with instructions for altitude settings and airbox modification. The published settings are for use with stock exhaust. JD Jetting can be contacted for recommendations for various aftermarket exhausts. I'm running it with stock exhaust and it made a nice difference to the all around performance.

Hats off to you for riding in the dry sand in the image. I generally avoid deliberately riding in sand, preferring to fall down by riding in mud. Understand that in NM sand is harder to avoid... if sand trails were my only option I would carry a small dependable compressor and drop my tire pressures for the sand and air back up again for the hard roads. Keeping your total weight as low as possible will help, leave the extra stuff you don't need at home. Jetting your carb properly will help in sand as the engine responds better to throttle input, and there are no flat spots. Keeping your weight low and back helps, like the lizard. Not sure if muttering and swearing helps...

Cruise control: I use a Cramp Buster from time to time - it works nice and gets out of the way in the tank bag when you don't need it.

The best bolt on modification for sand: take your licencse plate and bolt it on a 70hp KTM that weights 2/3 what a KLR does.

Speed is your friend in soft sand. The faster you can go the more stable the bike will be. Also shifting your weight towards the back of the bike will help some. A KLR is front end heavy and there's not enough power to float the front like you would on a dirt bike but moving weight back by sliding back on the seat or standing and moving your butt over the fender will at least make you think that it's helping!

Not needed my chain has never hit the airbox like they show in their ads. I've bottomed out my shock multiple times on trails before I had the sense to slow down! The suspension is kinda like a built in speed governor!

It's a 35 horsepower motor and that's where I notice it. The git up and go has got up and left by 70 mph. Plan your passes in advance.

JD kit good idea, adjustable mixture screw not needed unless you change altitude drastically on a ride. The CV carb is good with moderate changes in altitude you don't really need to fiddle with the mixture IMHO.

The bike has to be sitting level and not running for a few minutes to let the oil settle back into the trans.

That's all I got

Lar the Mod page is your friend and that hose trick is on the bottom of that page.

The hose trick works well for me as I run 70 miles daily on the slab. That being said a Throttlemeister is on my short list. Have fun.

I'm somewhat puzzled now. I've read in several places where people have tried to get more power from the 650 thumper and very little is practical. Why would a V-Strom 650 twin get 60 hp (if it really does) and we only get 35 hp ??

I googled the KTM and it sounds pretty great, but I'm not sure about the power claims. If I remember right, 650cc = about 40 cubic inches. On a fairly mild engine, 1 hp per cubic inch was always a standby. Snoose it up a bit and quite a bit more can be had with a little lumpier running.

Someone - several someones - have said the single won't give the power of an equal displacement twin. Why not ?? Now we see the single cylinder 650 KTM claiming 70 hp. Granted , it's FI and all, but that won't double the power. Have they snuck a mini-turbocharger into those things ??

Hi biglar!
Your question brings up mine from a short time back. Look up the thread KLR Power Mods and read on. As near as I can determine to this point the Klr needs to be modded to breathe better to get more power. A little more compression helps too. Of course horsepower = money.I am going to be pursuing this through the winter. As I find out more I will share it.

As far as sand, lowest tire pressure possible, stand up riding will help stabilize the bike, go as fast as you can will help stabilize. There is a road I ride very similar to that one you were on. The full knobbies at 12 psi(Pirelli MT 21's) were much better than the factory dunlops or Mefo explorers I tried before. You must have bead locks to run pressures that low. Ride lots Experiance helps too! I sucked in the spring,much better by fall.

The KLR is a 20+ year old design. There has been a lot of development since...

450 off-road bikes are pushing 55 horsepower, 600 sport bikes are kicking out 100+. All the reviews I've read of the KTM 690 rave about the motor, 70 horsepower? Not at the rear wheel more like 55.

A Wee Strom does indeed get 60 at the rear wheel there are plenty of dyno runs confirming that. It's renown for it's reliability so the engine is not stressed at that level of power output.

Haha........looks like we're both suckers for punishment.

I should clarify, tho' - I'm happy with my KLR and enjoy riding it. My aim is to maximize its potential but I'm not going to get into hot rodding the thing. All that in my last email was curiosity more than anything.

Bet people in the US wouldn't think of sand like that being in Northern Canada!
There are many simple mods on the site that most anyone can do which will help greatly with drivability and throttle response. You can look in the "common mods and issues" thread for some of those. If you have a problem or question the people here are more than willing to offer their TwentyTwoCents!! That will be funny later.... The wealth of knowledge here and the willingness to share it is second to none!
