Smile Rear tire position, chain tightness, studded tires

     

Thanks for taking the time to read my question.

I am putting on ice tires (IceKing with Marcel Fournier studds) and i need to move my rear tire back so that the studds don't hit the "armpit" of the swing arm. If i move it back as far as it goes i have a space of one link missing. This is fine as i thought i could get another master link and use the cutoff from my chain that i kept. The problem is the chain is too slack and i cant go further back . i could move it forward but then i would only have half a link space which of course doesn't work. I can move it forward more so i have no space and i can join the chain with the master link but there isn't much slack and the studds look really close to the "armpit".

I'm not overly mechanical and can't figure out how to solve this.

BTW, i determined spacing by putting my chain on my bike and having the two ends of the chain on the rear sprocket to see how many "U's" are left.

I have a 2007 YZ250 if that is helpful.

Thanks!

I put on a 13 tooth front sprocket, one less than stock. This is the same as half a chain link.

I would determine what leanht i need ether buy that sze or have one made. When looking at what leanth of chain u have to consider front and rear sporket size. determine how far back it needs to move to be safe to clear the added leanth of tf the studs.

Thank you for your reply here too bjunior

The different front sprocket solved my issue and I didn't have to buy a new chain.

Some claim adding more than 1 masterlink makes it weak I have not tried it.
