Call me unconvinced about your speed estimate (unless you were going downhill). It takes quite a lot more than a stock kit and sprocket to do 45MPH with an HT motor. Still, I'm guessing those are 700c wheels, which would give you a bit more top end than a 26"er.

In the top pictures, I see that the stock air cleaner tubes are pointing up. Those should be down, like in the last picture, to keep road trash out. The other thing I see is that the chain is way too loose. Snug that up before it jumps off and throws you down like a rag doll. You might invest in a fuel filter, because the cheapy plastic one on the inside of the petcock is junk.

Apart from those few things - nice clean build. I've got a build going on a similar bike, with those flat bars - do you get a lot of vibration through those? Mine seem to be pretty harsh.

My speedometer may be off. The directions say it should be exactly 5mm from the sensor. I will test it by riding along side my roommate's car over the weekend. I will also swap the intake as suggested. I flipped it over thinking the air would be cooler and more direct from the top, but I did not take in account the dirt. Also, the chain is very snug imo. Should it be so tight that I would put muscle into it? How would I test the tension? I will also be replacing the spark plug, and adding another fuel filter. What type of store would carry all of these supplies? I was thinking any auto parts store, but idk.

Thanks for the information and prompt response. All feedback is welcome and appreciated.
