Recommended Chain Slack '07 Te 250?

Does anybody know the manufacturer recommendation here? I can not seem to find it anywhere in the manual. Thanks

I'm guessing 35mm. It's not real critical tho; too loose being better than too tight.

I rarely go by factory specs- especially KTM which always seemed tight to me.

Unless the bike has a front sprocket centered at the swingarm pivot then they are all adjusted about the same.

Best way that always works is put your chest on the seat and reach down and grab the swingarm and compress the rear shock until the center of the front sprocket the swingarm pivot and the rear axle are all lined up in a straight line. That is the point where the chain is the tightest and you should have about 20mm of slack.

yeah, this way is definitely the best technique (IMO, 20mm might be a bit much. maybe 10mm? eh, probably not a big diff).

Lankydoug's method is the exact method the 2007 factory manual uses- except they recommend 0-2mm (!) clearance between the chain & slider when pushing the bottom of the chain up (so less clearance is a looser chain). Here's the excerpt from page D.37 (141) in the multi-language manual which you may already have (english is the 2nd language). The first picture is what LD means by having the sprocket (A), swingarm pivot (B) and the rear axle (C) all lined up in a straight line. This technique works on any motorcycle with 2 sprockets.

I don't use my chest, but instead use a ratcheting tie down; but whatever works for you. after you're done, note how much slack is in the chain when the suspension is relaxed and use that number as your new chain adjustment; avoiding future gymnastics.

good luck.
