The bike developed a squeal at startup. I have been riding 30-40 miles daily to get a good break-in, plus it is fun. It also started sputtering at extended WOT.
Checked the fuel flow, and it was a trickle. I thought the zoombikes petcock was better than the old brass one, but I guess not.
I pulled the gear cover, it is a bit more work because the shift kit mounts there too. In my hurry to build, I neglected to grease the gears, and sure enough it was bone dry with metal shavings. I greased it up and put it back together. I ran a drill bit throught the petcock, and it is flowing great now.
The squeal is gone now, and it certianly is quieter. I think it picked up a little too, it was 41-42 on the flat with no wind.
I am running 40 at the top of 5th, still have 3 gears left. I am thinking of dropping it down to the 10 tooth to see what that does. I am still getting my butt kicked by the wind, could only do 30 on one stretch today. I hope to add an expansion pipe soon and pick up some more HP and TQ.
