Check out the CBR stuff. Like I mentioned earlier, I know that some RC51 guys have done this with the CBR stick coils, and the RC51 and Fifth Gens share a lot of things.
Im sure both stock coils work but if theyre using cbr coils then theyre probably the same as my gsxr sticks seeing that kaldek got the same 1.6 ohm reading. I'll just need to mosy on over to a rc51 forum and do some sneaking.
