i just got a arrow i just want to make sure that i am doing this right...First i am going to break it in with the enclosed break in shim. I am to run the motor WITH the shim in it for 1 gallon, after the first gallon i am to take out the break in shim and re adjust the tune on the motor and let er rip correct?

and compared to the VZB line, this engine feels similar but IMHO will blow the doors off the VZB, its more power everywhere, its still smooth and all but its crazy fast. it screams. was really surprised by it. its closer to the VZB Speed imo but with a little more pep. about the same run time. mine still is new and i cant wait for it to fully break in and really make the power.

my understanding is that shim is used for 30% fuel. 20% for stock shimming. but im sure someone will have 100% definite answer.

wow that good huh? but i thought it was the same spec wise as the vzb? and is the crank a little more hardened then the vzb? Sounds good though

i never like the VZB, i had a few and they all felt weak, this one reminds me of the JP modified one, but i still think it has a little more than it, it might just be putting the power to the ground, but it gets going in a hurry.
