looks like it raises RPMs from 11200 to 12000 and adds 3hp.....suppose to add more time in between shifts.....
Anyone have any real world experience with this product???

A friend of mine put one in his crf250. In short they are garbage. It gave a weird hesitation just above idle and quit running when it got hot. He put the stock cdi in and lived happily ever after.

I'd be really hesitant to raise the rev-limiter above factory specs.

Had one on my 2006 YZ450F. Ran fine, but starting became a problem. Went back to stock, all is well with starting.
