Update on the coil overs!! I installed them today, very pleased! I will be going to the dyno soon to see actual results, but so far this is what I know.....08 honda 600rr sticks do work, one mod though, they felt a lil loose in the spark plug hole, simple fix, I put a high temp o-ring around the shaft, made it solid, and weather tight. Also the sticks require a studded spark plug(removable tip) the ngk's dont come off, so if you will notice the rc's can also use a denso plug "IK27" same temp range. it has a removable tip. I had bought the harness that goes with the 600rr sticks and simply cut the coil power plug and soldered them together, coverd with high temp loom. removed old coils, huge diff in weight.....if your looking to shave some pounds at least. I feel the throttle has more responce....but the dyno will tell, my wires on the stock coils as you know are not replacable and needed to be replaced, this solved that. Ill update later on the dyno!!
