You HAVE removed the black evap. cannister right? That can also cause popping after it fills up with fuel.
Thanks! Hope to keep it looking sharp but I am sure it will not look this good again

Yes, Black Evap canister is gone. Going to adjust TPS and see if that helps. Is it best to adjust by ear or use a meter? How could I check for an exhaust leak?

Hi guys, and maybe mams,

I recently bought me a new 500 exc 2012' and still am only visiting it in its garage beeing down on my knees...its her hireness..what a bike.

I decided not to visit any dealor exepct ordering spareparts and having a smalltalk.

1. Service at 3 hours...no loosend srews, only few (3,4) mini small metalpeaces in the Screen.

2. Service at 10 hours, no metalpeaces, only usual abrasion in form of paste at the magnetic screw. Valve clearance perfect in the middle of the tolerances.

Takes far less fuel than my pals 530. Runs perfectly smooth.

By the way...my dealer told me that they get them desmogged and without (germany) and the other crap from ktm. They would have to mount it....ofcourse they didnt :-)

People here with more than 200 hours on the engine?

Have a nice ride

Maintenance on this bike has been minimal. Keep the air filter clean, grease the countershaft sprocket splines, and change the oil every 15 - 25 hours depending on how hard you ride. The valves clearances are still within specs. The dealer said the engine would easily go a 1000 hours before any work.
I am using Dunlop 606's front and rear and they work and wear well on the street and dirt. The last 606 rear tire had 1800 miles on it when i changed it. I run 17 psi front and rear for the street and 12 psi for the dirt.
Gearing is 15t - 49t street and 13t or 14t - 49t for dirt depending where I am going.
Question: why grease the splines on the countershaft sprocket?

Thanks, E-Ticket

E-Ticket - Awesome thread on KTM Talk with your Wee Beasty. Thank you.

It's not just grease on the countershaft but a Moly Paste that is utilized for driveshafts and final drive components. its is supposed to protect the driveshaft splines your countershaftlt sprocket bolts to from looking like my 525 splines.



I've bought some to give it a try and see if helps. The above part was after 470 hours of dual sport riding. Apparently whacking the throttle opened on pavement is not kind to the driveshaft.

Hey guys just picked up my 2013 500 exc here a few weeks ago!

Finally got a second set of wheels and tires. This bike is stupid awesome

She is de-smogged, custom fuel map, and cap out of the pipe.

Wholey crap-o-la ...!!!

Supposedly the new Belville-washer, diaphragm clutch on the 350 EXC-F has a cush hub built into the clutch basket. Is is the same for the 500 EXC-F's?

Regardless, I think that I will do that the next time that I have the countershaft sprocket off!
Any recommendations on any specific-brand of grease? Or just make sure it's a known, high-quality brand?

BTW, would you mind if I posted your pic and mileage on the Wee Beasty thread? That's great information!

Cheers, E-Ticket

The 500 has the same rubber dampers on the clutch hub, but I'd still get a cush hub if you are going to put on lots of dual sport miles.

Regular grease is no good, but Honda Moly 60 paste supposedly is.

Any automotive grease will do. I am using Molybium Multi purpose grease on the splines. I change countershaft sprockets for where I am going to be riding and after 230 hours the splines still look like new. So far the riding has been 60% street and 40% dirt, not by choice but time restraints.
According to the parts manual the 500 EXC has rubber dampers in the clutch hub, same as my 1967 Triumph Bonneville did so I think a rear wheel cush hub isn't necessary.

I am using a 606 130/19 with a 120 link chain. I use the longer chain for two reasons. First is that it moves the rear wheel farther back on the swing arm which makes the ride a little smoother. Second, the longer chain allows me to switch gearing from 13-49 to 15-49 by just flipping the axle chain adjuster 180 degrees and moving the adjuster screw about 1/8 inch.
With the 15-49 combo there is about 7/8 inch clearance between the tire and shock guard.

Read this first: TPS adjustment post 3631

For an exhaust leak look at where the header pipe connects to the engine header to see if it is loose.

The wear is from Fretting, (Wikipedia): The ASM Handbook on Fatigue and Fracture defines fretting as: "A special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force." Fretting examples include wear of drive splines on driveshafts. Fretting damage in steel can be identified by the presence of a pitted surface and fine 'red' iron oxide dust reminiscent of cocoa powder. Strictly this debris is not 'rust' as its production requires no water. The particles are much harder than the steel surfaces in contact, so abrasive wear is inevitable; however, particulates are not required to initiate fret.
Lubricants are often employed to mitigate fretting because they reduce friction and inhibit oxidation.
Grease the splines.

No problem just make sure to identify that it's a 525 driveshaft and not a 350 or 500.

The Honda Moly Paste 60 is what is recommended by Honda on the splines of shaft drive street bikes for minimizing wear of the splines. However keep in mind these street bikes also have cush hubs, our dirt bikes do not. Time will tell how effective lubing the splines are but I'll be surprised (or astounded) if its as effective as a cush hub. Hope I'm gonna be astounded.

Bengt Phorks thank you for posting the description of fretting, good stuff.
