Got my MANTRA back today from Drake, if you have given it some thought , the EBIS breakin.......trust me Do it! Send it to drake for $50. Get it back in a week ready to go! And the motor just feels different. I can't explain it , but it's not like when we break them in the old way. I'll keep you posted once I get it over 200°. Rightnow the power I got at 170-180° is making this already my favorite.
