Axel nut sizes and torque settings??

Well I've run into my first issue at only 200 km...

My front sprocket shaft seal is leaking. At first I thought it was just excess chain lube, but no, it's definitely leaking. I understand a tight chain can cause this. When I sat on my KLR and checked the chain tension... it was super tight. Damn dealers! I should have been more careful. I'm hoping that loosening the chain will solve the problem without me having to get work done on my KLR.

I need to know what the axel nut sizes are. The left looks to be around 18 or 19 mm. The right nut is definitely bigger. Has anybody adjusted their chains yet?

I also need to know the proper torque settings for these nuts.

Thanks a million (and wish me luck)

The book says 58 ft lbs for the front and 69 ft lbs on the rear. I think the nuts are 22 and 24 mm, I think 19 22 24 mm sockets are needed, maybe a 27 mm too. I'm not sure and it is too dark outside now to check for sure. 27 mm may be the steering bolt.
The chain adjustment should be done with the bike on the side stand, and you should barely be able to push the middle of the chain up to touch the swingarm.

Today is the first day of the rest of your life.

I have already adjusted mine and my buddies after installing the 16 tooth front sprocket. We did it as the book suggested, but I found that mine was way too tight once I was sitting on it. So with Frank's help, we would each sit on our respective bikes and the other would adjust the adjusters back till there was about a half inch or so of slack when the chain was pushed up with fingers. I may get flamed pretty good for doing it this way, but it really seems to be the best way to adjust the chain to the rider's weight, instead of a generic setting.

Previous ride was a 2007 KLR Black/Silver, I miss it..
Looking to get back into KLR's sometime soon.
