can someone give me a little insite? i had put a 15 tooth sprocket on my 2003 vfr and it threw off my speedo. i went back to the stock sprocket to correct the problem because i am about to go on a road trip. well, the speedo is still not reading. can someone tell me if this will correct its self or am i going to have to get one of those speedo menders? thanks for any assistance. thp803
