Everything is tight at this point, your kicker alignment sucks. It either rubs the pipe or frame even though I clearanced it, "the frame," after setting it up when I did the motor mounts. I'm hoping to hit a half gear on the nuetral setup in the case sprag, or I'll get a kx420 kicker & bend it with the torch to get a fit between the frame & pipe. The CPI does kick ass over the FMF or Procircuit for fit. The springs for attaching the pipe are a challenge but look at broken frame pics of AF conversions on the net & you'll be hessitant to cut like me. Just a bit of die grinding in the kicker C will help & but do it before you powder coat. Even after that you can trim on the kicker stubb & gain a little more. you will have to mount the jug & then roll it into the mounts to assemble it which is a struggle for some. The 3.7 gallon tank is a must, after pushing a bike 2mi home 3 times you'll see Y , it should clear the plug & head nicely . Those stock 250 tanks are only good for 1hr & 45 minutes "no longer"
