they should fit they have a smaller gap 12R .032 vs 10R .036. Not sure if or how that would affect performance but they should fit. Really that aren't that expensive and you don't have to change them that often just get the proper ones. You might be able to exchange them if they're new.

This is probably true actually. Would be worth giving it a shot. :+1: to JLG though, Id just get the ones that are supposed to go into it.

sorry I'm on crack I don't know where I came up with the 12R. the cr9ek is multi vs single tip as far as I know. The gap is now quite a bit smaller at .028. I wouldn't use them. They would still probably fit though as the profile would most likely be quite shorter.

Don't do it...your bike came with your specific size for a reason...exchange em, or wait till you can buy the correct size...or you can just do it, and let us all know how it works out for you...

Yea, having to take the frame mounts out sucks. You have to get the right tool combination going to easily remove/install the frame mounts and plugs...GL :thumbsup:

I am running cr9ek plugs and loving them, you just have to pull them out once a year and clean the threads that is in the combustion chamber, that's about it.
