I felt the TA was just too compromised. I didn't like it offroad, and I didn't like it onroad. That said, for a bike I "didn't like" I owned it for 6 years.

Now if the TA had a kickstart like the ADV it might be a different story . Since I figured out the kicker, I've been starting the KTM nearly every day for the last week just because it's so damn cool.

2 x8000 km trips on mine, and about 4000 2up, not vibey to me. I love that bike even though my cam roller failing ended up in a bunch of damage. Not a big deal if you plan for that maintenance near 30K.

I just read the thread on the neoprene fork guards. It's mentioned to shorten them, as they will affect the suspension if not... Anyone know how long they should be???

You can slid then up and down.

Currently mine are 6 " long, maybe they are pieces of others I cut up.

You could cut a set in two and have replacements, they get worn looking after a while.

They mostly act as additional wipers for me.

sorry for the cross posting. not getting bites at the other thread.

anyway, since it's 2 years old and over 6k miles, i decided to get a new bearing. JAF 6205RS (made in japan @ $30). same OD as the NSK 6205.

i checked the ID of the carrier, 2.0442-2.0445...

based on the above numbers, the interference is over .002. that's a lot....

that explains why the bearing was tight. the outer raceway was getting crushed causing it to collapse.

we do a lot of press fit bearing installation here and the typical interference is .0005 - .001.

does anyone has an uninstalled oem ktm bearing ? OD? :

what's the ID of your carrier?

my next move is machine the ID of the carrier by removing .001 of material.
and thanks in advance.

Is the bearing you are talking about the double race one in the rear? If so there is a bearing that is exactly the same, but with different part numbers that works...it is for a Chevy truck I believe. Cheaper and easier to source than the part from KTM. Let me know if that is what you are looking, I think I still have the box for the one I used in my '02 somewhere in the garage.

Are you sure? I thought the rear sprocket bearing was a double race. I'll dig out the box and see what the part number is. Shouldn't have to machine anything off it.

i'm positively sure. ktm switched to 2 bearings on the newer models, my guess from 2005 and up

it's item #28

my mistake, double race but 1 bearing. i got it mixed up with peeps using 2 bearings that are narrow.

i believe you. what's the outside diameter of your bearing, metric and std (4 decimal places) if you can?

thanks.

I have an NSK bearing from my 03 cush that pretty much measure 52mm spot on... The bearing number I replaced it with NSK- 3205b-2rsrtngc3, I picked this up from a bearing supply place for about $30...

Answer - circa 23,000 miles, just returned from a 6,000 mile trip from England, Spain, France, Morocco and back :-)
Condition, a little rattlier than when it left.. probably going to ride it through winter and rebuild (pay for a) - in february.
It probably should have been serviced while out there, but c'est la vie.
I would invest in the new rollers - the bigger one already looks worn, causing (worse) cam wear too. But You should know it if You are planning rebuild. ;)

Pop the grease seal on the old onee an completely wash it out remembering it is a two race bearing. Get it very clean, then regrease it and replace seals. reinstall it and run it another 20K miles.

Every 20K miles...Remove again, repeat.

I doubt you wrecked it, it is a tough bearing. Mine has run with a little 'hitch' for 50K miles. There is no play in it, just a very scant roughness.

Heat the sprocket carrier assembly with a propane torch to instal/remove.
Get it fairly hot.
to install, bearing in the freezer, use some lube if you must.

Just try not to beat on the inner race, it sometimes divots the metal creating that chunkiness feel. Use a puller if you can
