frame

I have two questions. Bear w/me please I am an uber newbie in this subject and it does not help at all that I'm solely a visual learner. Ok, first question: is there a way to make the 2 stroke engine quieter? Second question: what frame is most recommended for a girl? I'm more of a mountain...

I am looking for a RAW engine, but I am skeptical on if it will fit my frame. The dimensions of the frame are (top)18" x (bottom)22" x (height)11.5". I don't know if I should get a slant angle engine or a regular engine. I am looking here for my engine. I have heard of that mounting it in...

Douse any one know if it is ok to cut off the sunspot beam from the Tim Hornets bicycle i have it circled in yellow in the pic attachment. is it just for looks or its is support as well.

Just a FYI, if you have an angle plug head on a smaller framed bike, you can easily create the clearance you need by flipping the cylinder head... YouTube - ‪engine mounting trick, reverse the head‬‏
