Re: Love my Bike but...
Welcome. I've had a motorized bicycle about two months and I had a friend put it together so it's new to me as well.
Going to add some after market and doing some experimentation on the intake side.
One small step at a time works for me.. It's funny but I find calm and solace when I sit on my bucket next to the bike to do even the simplest things like wiping the bike frame.
I think one either loves MB's or doesn't right from the start.
Sounds like you love it.. Good for you friend!
