my 1997 honda cr 250 was not getting spark. went threw all of the tests and results told me the cdi was bad (getting intermitent spark). drove all the way to buffalo mn (a 2 hr drive for me) to get a cdi from a guy that claimed his was from a 97 cr 250. got there and his cdi was completly diffrerant from mine, however he did have the cdi stator and coil and told me it would work if i just used all three. bought them for a deal and got home, mounted everything in there, and wat do ya know, NO SPARK. looked up the part number of the cdi box on google and figured out it was really a cdi from a 99.(im guessing the stator and coil are off a 99 to). What i am wondering is if these parts from a 99 should work on a 97. He tells me i may have a bad ground, however i cleaned it up pretty good and am still not getting spark. Any responses will help. i have been trying to figure out the problem of my bike for almost a month and I JUST WANNA RIDE!
