Big Gun Rev Box....anyone use this

5 posts in this topic

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.

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???

from the search I did it does not look too good,,,,any other opinions?

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