Ok so first I have the stock chain. I was changing the front sprocket from a 15t to a 14t. My rear sprocket is the stock 39t. I loosened the castle nut, then tightened both adjusters equally. After it was tight enough I tightened the castle nut nice and tight. The bike was on the side stand. After I was done I put it on the center stand and washed it. Then put it back on the side stand. thats when I noticed that the chain was completely sagging and lose. My chain only has 7500 miles on it so I dont think its worn out. I lube it regularly. I tightened it again and rode it. Sure enough 5 minutes of riding and the chain is pretty loose again. I feel like something is wrong with either my castle nut or one of the adjuster nuts. If I cant fix it myself I might have to go to the dealers to get it looked at. Anybody know what could be wrong? Oh my tire is far back in the swingarm.
Always adjust the chain on the center stand. The wheel needs to be off the ground.
How did you tighten it? Just wrench it? GET A TORQUE WRENCH. You might be really surprised how much tighter it needs to be after seeing how much torque 60ft-lbs is. Also, check to be sure the adjuster nuts, they should be tight as well.
Yeah +1 to torque wrench. .. 60lbs is a fair bit on standard length tools! , torque wrench is also longer which helps with applying pressure!
I never torqued a rear axle nut for decades and never had a problem. Then one day I found my wheel had slipped out of place and I tightened it again and it slipped again and when it still slipped once again I tightened it with torque wrench. On the road locally the rear wheel all of a sudden was locking up with a bad wheel bearing. I got it freed up and got home and took it off and discovered spacer #9 was missing. It had been lost when the cush drive was removed for a tire change. Take off your wheel and pull out spacer #10 and check. You can see spacer #9 inside the cush bearing if it's there, If not replace all wheel bearings and spacer #9. When spacer #9 is missing tightening the axle nut puts a heavy side load on the left wheel and cush bearings.

Good call Jack...my bike was missing one of the spacers when i got it as well...ended up blowing a bearing to pieces. Made the new spacer on the lathe and yeah...WAY better.
Ill take it apart and look at it. Thanks for a link
