> Is there someone in the area you would recommend to tune a 636 motor? I ask because I have one going in something in the near future and while the motor is stock, the exhaust is going to have to be modified a bit. Will still be using cycle parts and a slip-on or similar motorcycle can, but have to change and reroute the midpipe, which I’m sure is going to screw with the AFR’s on the thing.

I asked the same question in this thread and you can take a look at the replies, my question is on post #12.

Why not just get the autotune if you are using PCV?
