Help! Carb Problems and Chain Question

I've got a 99' KLR650 I bought used and it seems to have developed a problem in the carb. Normally, I get about 55 MPG but the last tank only got 44 MPG and I've noticed the bike is making everything (me, jacket, tailbag, the surrounding countyside, etc) reek of exhaust fumes. I've checked the carb tubing to make sure it's not clogged and swapped the spark plug about 400 miles ago. Is there something specific to look for as a cause for the lower mileage/dirty exhaust? :lol:

As for the chain: Has anyone heard of "Super Links" chains and are they any good? My KLR has 12,800 miles on the original chain sprockets and is due for replacement. I found these chains for $38 bucks, but wondered if anyone has experience with them. (Good or bad)

Thanks for the help!


Never heard of Super Links chains. Google them and see if you can find any info. Be aware tho, you get what you pay for. A low buck chain may wear/stretch prematurely and that prematurely wears the sprockets that might otherwise have lasted a lot longer with a quality chain.

Still running stock exhaust?

Air filter clean?

Was the new spark plug the proper plug and gapped correctly?

Make sure the bike isn't pissing fuel out the carb vent/overflow, setting still or when going down the road. That would suggest trash in the needle valve or float levels off.

Is your bike using much oil?

That might be the reason everything stinks as unburnt oil will stick to everything and it stinks.


I couldn't find a thing on Superlinks chains on the web. They are part of the discount package for chain/sprockets/chain breaker off

The air filter is clean and I'm having trouble remembering exactly what plug it was but it was the same as the one I took out and was recommended by the Clymer manual and was gapped. I do have the stock exaust and I was going to pull all the 3 bolts out the bottom to "clean" it (per the manual) but the first one I tried snapped off. Too old and corroded I guess. I've hit the other 2 with WD-40 and after they soak awhile I'll try them.

It doesn't seem to burn any oil that I can tell. There's no smoke of any kind and I've owned it for 3000 miles (I've done 2 oil changes) and never had to add any oil.

Thanks Fellas.

      Hello guys,New to the forum.
      Quick question,I have a 1994 klx650c i recently purchased and am in the process of upgrading it.
      Have a trial tech vapor speedo ready to fit,however just wondering about the stock instrument gauges etc.
      Is it literally a case of unplugging the old dash and fitting the Vapor? Is the Dash used to complete the stock wiring circuit? e.g-if i unplug it and leave it unplugged is it going to effect the running of the bike? What about the dash lights,how would i go about wiring these up?
      electrics really isn't my strong point,got the basics covered but way too complicated for me.
      any help greatly appreciated,any more info you need please feel free to ask.

      Hello, This is my first post and I'm new to TT.  I recently acquired a 2008 KLR650 (which by the way I absolutely love) and I'm working on adjusting my valves, I already measured its clearances and found this helpful online calculator: however I'm unsure of what the shim factory setting size is and it is essential to get the right shims. Does anybody know what the factory settings are?
      Thank you!

      Recently we did a project bike with Dirt Bike Magazine's KLR650 and we were pretty excited about the results.  Check out the article on this fun project here:

      Hey guys,  
      A super duper THANKS for all the help, laughs, and fun I've had here, and the bike I put together based on advice and lots and lots of reading material you've provided on what is the best vehicle forum I've ever encountered (been on many over the years). . 
      Just when my bike was absolutely the bike I wanted it to be, my riding buddy (who is my father in law) bounced of his DRZ well up 4610 here in Oregon and broke his leg, and good. Tib/fib  job requiring rods, screws, plates, and a kitchen sink to put back together. If it wasn't for the MX boots I got him, and "forced" him to wear....there would have been all sorts of nastiness sticking out of the skin. No doubt about it, as both lower bones broke at sharp angles making spears inside his leg. As it was, everything was contained. He is going to be down for quite some time. I bought my drz to ride with him initially as he had a KLR650 and had an interest in backroad and moderate trail riding. On our first trip out (Brown's camp easy/mod trails) after about 10 times picking up his KLR with over-inflated 50/50 tires (mine stayed on 2 wheels all day long) he said "I need a bike like yours". Within a week he had his DRZ too! Then over the fall and winter we did all the mods and fixes to get them ready for this spring/summer.  It was kind of a miracle I even convinced my wife to let me get a dual sport bike. I'm 50 now, and have a degenerative vision disease called RP. Basically, I'm missing quite a bit of my vision field, but have decent vision straight ahead (unlike macular degeneration). I'm not in denial that good/full  vision is important for safe motorcycle riding on the street...and the reason I'm a 90/10 dirt/street guy. My argument was that we won't get hurt just poking around the woods, old man style, with occasional pavement work to connect trails (thus the need for dual sport over dirt bike).  Well, my father in law shot that theory down, but good!  He has dealt with so much pain over the last month, and met several dual sport riders in for riding injuries (some that make his look like a kid's day camp) that he decided he is out of the game. Unfortunately for me, that means I'm out of the game too. My wife is so worried I'm going to get injured badly, that it's not worth the fight. I don't want her and my daughter stressed and worried every time I go riding. My father in law was doing great on the roads and trails we've been riding. And just loved riding the DRZ. But he's 70 and looking at Jeep Wranglers with lift/tires for his forest adventures going forward. Not a bad call imo.  So...I've sold 2 DRZ's and a KLR in about 1 week (here in Portland OR, I could have sold 4 more DRZ's in the same time if I had them!).  His 1100 Honda shadow cruiser is on C.L. now as he is cleaning out the stable completely. Sad, sad day. It's only been a month since our last ride and I'm already missing the dirt big time. Even sold my daughters doodle bug. Oh well, life goes on. 
      Take care guys, ride safe (inside your skill level), gear up...and have some fun for me!!
