May be a silly question but I am having a hard time getting the front sprocket off of my Daytona. Is it a normal thread? Clockwise to tighten, counter to loosen?

Yes but they're a beatch to get off.

Martinyoung is correct. To put it slightly differently, the front sprocket bolt is a regular "lefty-loosey, righty-tighty" type fastener. It also probably has the highest torque spec of any fastener on the bike.

Easiest way to get it off is to put the bike in gear, have someone else hold the rear brake pedal down, & go at it with a longish breaker bar.

I had a little incident with my first bike that involved the chain snapping as I came off a stop light. To remove that sprocket, I had to attach the old chain to a piece of 2x4 in order to keep the driveshaft from moving. That was fun! (Umm, not.)

HTH,

I use an electric impact wrench that spins the sprocket nut off in a hurry. I use a torque wrench to tighten though.

I have it in gear, I have someone standing on the brake. I have tried a long bar. I have an air impact and it makes a lot of noise but won't turn it. I do have a small compressor and maybe I can't build up enough pressure to operate it long, but I do let it build up as high as it will go to at least get a good burst, but no go. Acts like either it was put on with an impact, or it is rusted on. Shouldn't be rusted because it was a new chain and sprocket shortly before I spun the rod bearing.

I stick a 2 by 4 through the rim and under the swing arm.
As long as everything is in touch with each other there should be no damage this way.
If needed the same can be done when tightening by putting the 2by4 above the swing arm.

Stupid question but did you lower the external tabs on the lock washer? Also, I'd try some penetrating oil. The 2x4 method's worked for me in the past, also I used a 3lb sledge on the handle of a really long breaker bar once I had a good deal of pressure applied.

Good luck.

I forgot to mention that I used Liquid Wrench 24 hours before removing the sprocket on the old KZ. Penetrating oil helps, & heat might as well.

I did go back and make sure I had the tabs out of the way and that I hadn't missed any. Not a stupid question at all, actually a very good one. I have thought about getting a torch and adding a little heat. I diduse WD40 but I didn't let it soak. Guess I will do that. then add a little heat, use the 2x4 and a longer breaker and see what happens.

Do try Liquid Wrench or Kroil; WD-40 just isn't the same.

I once had a similar problem. The bu88er just wouldn't shift. I was advised to get a good fitting ring spanner on and just tap it with a hammer and it will come off. IT DOES WORK. No force needed.

Thanks for all the help. Liquid Wrench for a couple of days, a long breaker bar, and a 2x4 finally got it off. My shop will never again be without a good 2x4. Now I can get on with replacing the engine. Thanks again.
