I understood that you could raise your rev limiter by 500 rpm without the code. Anything greater requires a code. Also the research I have done, you can raise it without the ignition module. But I have found it difficult to find information about it. When I think about it I had the new flash done this year and some people are saying yamaha increase the limit.
Oh by the way if i didn't say, thanks for all your help with clutching my sled.
