    I disagree that the klr was not designed to run at highway speeds considering the gearing and target market for this bike. There is no reason why a klr should not run 70 mph all day without burning significant oil. To accept anything else is just making excuses for a poor design IMHO.

    Interesting feedback! Question then - why do such a significant number of KLRs become oil burners?

    It seems that a few of you refuse to believe that higher piston speeds, and the increased stress on the rings, is to blame, so why do you think it occurs? :ear

    EDIT - no argument it shouldn't be happening.

    All of these KLR's are over 20,000 miles and none burn oil, just the '08. Kawasaki fixed the '08 oil burning problem under warranty.

    Good for you guys - guess there isn't a problem then! Seriously, the oil burning issue isn't just confined to the '08 model year. You didn't answer the question - why do YOU think the problem is occurring? ...if it's not due to higher piston speeds? It's pretty clearly understood by automotive engineers that there are consequences and limits to running higher rpms. The KLR piston ain't small - them's Harley sized slugs!

    I think most people will agree that at high speeds a lot of thumpers will burn some oil.

    The issue is that many of the 2008's burn an excessive amount of oil, like a quart in 500 miles. Very few years before do that, and most of the post 2008's don't do that.

    I guess my question to you would be why do YOU think the 2008's were so much worse than the years before and after?

    Most of the 35K miles on my GenI engine are at speeds of 80+ mph. Oil level is the same at every 2000 mile oil change interval.

    Bad run on the manufacture of the cylinder- piston- rings of the '08 model.

    We don't have that problem so I can't tell you why. I've never heard of the oil burning problem until the '08 model. My brothers Barbie does not burn/consume oil.

    I've read the '08 model year had a slightly changed ring design... don't remember the details (maybe someone could chime in with that), but seem to recall the ring type, thickness, hardness all were a factor. Am personally looking forward to 685 kit upgrade with the Thermo-Bob installed - slightly more power, less vibration and decreased oil consumption - all good. Haven't heard too many guys with aftermarket piston kits complaining about excessive oil consumption. I still maintain operating at higher rpms for extended periods places greater stress on pistons and rings - in my mind, it only stands to reason that the rings flex more and generally have a tougher time sealing. I've read this in car & bike mags, and heard this stated here too - it's on the internet - must be true! :lol3

    The pre- 08 pistons are known to occasionally break a ring land - the section of piston material between the rings. The piston design was changed for 08 to try to address that. The new and thinner 08 ring design pressue was about 3lbs - not enough. This could cause ring flutter and oil usage at rpm's around 5K. Some 08's had the bores oval too. The late Cary Aspy, of Schnitz, in co-operation with JT pistons, decided on a forged piston (stock is cast) that gave a 685cc displacement and that has a ring pressure of 11 lbs.

    I now have 36K on my 08 and the JT 685 piston (47k on the bike). It does not use oil ( about 1/8" on the sight glass) even after a 4k ( no oil changes), 8 day ride with several 7-800 mile days and many, many, miles and hours upon hours of running at or above 5k rpm. I have now done many rides like that.

    There are a lot of 'old wives tales', 'tribal knowledge', call it what you like, that are ignorantly spread around on forums about 'all singles use a bit of oil'. Decent piston and ring design, propely bored and toleranced piston and rings will not 'use' oil.

    Thnx for that. All engines use some oil tho... the thing is what is considered acceptable? ...and I'd imagine there are in reality many factors that could contribute to increased oil consumption; worn rings from abrasive dust getting past the filter for example...

    Hey guys,

    I've got some questions about repair work I need to do on my '08 KLR650. I bought the bike last year with about 4000 miles on it, and have put another 6000 on myself. The previous owner said it was broken in properly and maintained, though he didn't believe in lubing the chain. :D It's been running fine for me with a few exceptions which I'll get to, and the one big problem.

    The big problem is as follows. I drive the bike into work/school when I'm able, and given the price of gas, I drive pretty late into the year. One cold morning (about 18F I think) I was driving into work on the highway, doing 55. I noticed several puffs of haze form behind me, but since it was kind of foggy in places I thought it was just my exhaust condensing. I rode another 4 - 5 miles and then pulled off on an ATV trail to warm my hands up. I noticed some smoke coming from the engine, so I shut it down and took a closer look. The oil level had entirely disappeared from the sight glass, and the left side of the engine and my left leg were covered in oil. The smoke was coming from where some oil had got on the exhaust pipe. I only had a mile and a half to go to get to a gas station, so I drove slowly there and put some oil in. Since then I've driven another two or three miles, and see no sign of any leaking, but I don't have any idea where the oil came out of the engine. As I said before, the left side of the engine was coated, the right side had nothing. There are no visible holes in any seals, though I can't see the top end very well under the tank.

    On to the smaller issues I've had. When on a weekend trip last summer, my oil filler cap came off on the highway. I felt my peg getting slippery, so I stopped very quickly. I had extra oil along that time, but I couldn't find the cap, so I rode the rest of the weekend with a piece of foam and then a sink stopper stuck in the hole. I changed the oil right away when I got back, but I think there are still a couple of bits of the foam loose in there. The other smaller issue I had was that once the weather started getting cold, my oil sight window and filler cap became coated in white moisture residue. I put the watt-man radiator mod on, and that seemed to be helping, but then I shut everything down after losing all that oil.

    So my questions:
    1. Any idea where the oil is coming from, and how it could spray so much oil and then not leak a drop?
    2. I'll (obviously) be tearing the engine apart until I find what's the matter. Anything I should do while I've got it out of the bike and am working on it? I'd prefer not to put a bored cylinder on it; I just don't have the money for that now. But what is prudent to keep a 2008 running on long trips?

    Thanks all!

    I'm trying to title my 2008 KLR 650 in Wisconsin and the ole' DMV is giving me a hassle saying that the VIN is coming up as a "dirt bike." As we all know this is not the case. The previous title, which was from Illinois has it listed as a "motorcycle." The DMV is telling me that I need to locate a Federal Safety plate which will tell me that it's street legal. Anyone have any suggestions for me? Anyone have this happen to them in Wisconsin? How did you handle it? I should add I didn't go to the DMV window I just sent in the title hoping they would send me my new WI title.

    I see no peril in appearing in person before a DMV office for you; you may find knowledgeable help, and--regardless, your bike will still be a KLR before and after your visit--nothing to lose.

    Further suggestion; wouldn't hurt for you to enlist a Kawasaki dealership in your case. The dealership personnel may have relevant knowledge and experience to share in your case, and--it's in the dealership's best interests to empower a local Kawasaki rider for subsequent business.

    1. Finding the oil leak. Clean the bike well- with a water soluble degreaser - spray on, wash off. Ride the bike (on a dirt road) and see where the dirt collects. Several areas. There is an oil delivery pipe that sends oil from the left side to the transmission, the counter sprocket bearings and up to the head and cams. These attachment points and their copper washers may be loose. This oil leaking will be on the top back of the motor. If the chain was too tight, then it may have destroyed the counter shaft oil seal - oil will be coming out of that shaft area. Both are relatively easy to fix and no need tear the motor apart. Find the leak area 1st.

    2. Foam in the motor. I would 1st look at the oil filter area to see what was in there. Then definitly, and as soon as possible, remove the clutch side cover and check the oil screen at the bottom. If this gets blocked, then it would starve the oil pump and if that happens, it will 1st toast your cam bearings.

    3. White moisture residue in the sight glass. Not a big issue. A by-product of combustion is acidic water which does not get expelled from the exhaust, but leaks into the crankcase and is usually heated off/evaporated when the motor (oil and crankcase in particular, gets up to operating temp. This evaporation does not occur if all you are doing is short trips in cold weather. Those of us who have the thermobob have less of a problem as the motor warms up quickly and stays at a higher temp (195) than the 160 degree stock stat.

    4. Leaking oil and using oil are two different animals. Fix the leaks and then see what your oil usage is before sweating over piston replacement.

    5. What is prudent for keeping an 08 running on long trips?. Oil and gas is the short answer. Proper maintenace, including lubing and adjusting the chain helps. The long answer - another day. However, the best and most important answer to keeping any motorcycle running long and reliably is what is between your ears! Information (and knowing where to get it), knowledge and a KLR, as simple as it is, will help you there.

    The design is okay, it's the quality control in the building process. :evil

    Hi guys, I've been wanting a KLR for years and now is finally the time to get one. I've looked at a couple on Craigslist and really like this one, but there are a couple things I'm a little concerned about. Here's a link to the post but I copied the text from the post so if you don't care to see the pics:

    This red 2008 KLR650 has good TKC80 tires (rear is brand new), battery, etc. 99XX miles. Runs well and looks good. Clear AZ title. This is the first year of the latest redesign and it is much smoother with a much more comfortable seat than the earlier model.
    Extras include:
    High strength sub-frame bolt
    Progressive suspension front and rear
    Fork brace
    Stompgrip tank knee grips
    Stage one carb / jet kit
    14T countershaft sprocket
    Happy Trails skid plate, radiator guard, side guards, and bag racks
    Optional higher Kawasaki windshield
    Hyperlight blinking brake lights
    Modulated headlight
    Turn signal beeper
    12v cigarette lighter type outlet
    Stebel air horn
    I will also include a pair of clapped out Fastrax bags and a Cee Bailey headlight guard that have survived a trip to the Arctic Ocean.

    And the link: http://phoenix.craigslist.org/evl/mcy/3554394187.html


    Here are my concerns.

    First, he's the original owner and he had oil burning issues when he first purchased it. The dealer addressed the issue by replacing pistons and rings, which he says resolved the oil burning problem. I've read a little about the 2008 oil burning issue and I was under the impression this procedure didn't fix the problem. The guy is a real motorcycle hobbyist and does a lot of work himself (he's got two older bikes he takes up to Bonneville to compete each year and does the mods himself) so I would think he would have just done the top end rebuild himself if this didn't fix the oil burning issue.

    Second, he claims the odometer got stuck at 2,500 miles, so the 9,9XX miles listed in the add is an estimate. I plan to take it to a nearby shop to have it checked out so I should be able to make sure it really isn't 102,500 miles. My concern with this issue is resale value. I'm wondering if I'll have issues selling it myself later.

    I'm a pretty good judge of character because of my line of work, my BS meter is pretty accurate and I tend to believe the seller, but you never know for sure.

    Lastly, the price is pretty firm, think it is a good price?

    Thanks for the advice,

    Todd

    I've seen a number of OEM fixes that did work...and others that didn't. Worse case you can upgrade with an EagleMike big bore kit and be done with it. Relatively inexpensive...

    2500 mileage discrepancy is not even a blip on my radar. Fact he told you lends credit to him...

    If that is a DynoJet kit installed its running way too rich. Expect mileage in the low 40's...maybe even upper 30's. We can give jetting changes that will work great with that kit.

    Its a fair price. I have a buddy about to sell his 08. He has 20K and his was an oil burner to the point the original owner let it run low and toasted the topend. He simply swapped out the engine. He's added some nice suspension upgrades as well as addressed the normal KLR stuff. He'll be asking about the same price.

    When/If you purchase...check for deep hole syndrome (all 2008's had it), visually verify Doo lever/spring or best to just upgrade both, pull the rear suspension apart and lube the bearings. The Prolink pivot bolt is first to get seized. Understand how the side stand and clutch safety switch works, maintained and how to disable either/both in the field if needed. The early GenII's have 6 common rub thru points on the wire harness. There are several more that are coming to light. Simply strip the bike down and go thru the entire harness. You'll get years of trouble free service...
