Just broke in and race tuned. This thing has great torque! Run times aren't the greatest (under 9min)but if you want power this has got it. Great response. Picked up while on sale to give a try. Might have to get another for back up. Mine came with the upgrade kit separate, so had to install the button and longer low speed needle. Used with a 053mr dp pipe and header and it was pulling the front wheels off the ground on good launches. Just received the 2058 pipe set in the mail since I've read lots of good reviews of it paired with this motor. If your looking to get a new motor and this one is still under 200$ don't think twice, you won't regret it
