Got my first ever 4 stroke kit today. Now I have built mini bikes, put 212's on bikes, etc. This is the first 4 stroke kit engine I have ever bought. I'm building a bike for my midget apprentice. She's about 4' 8" and 90-100lbs. The bike I am using is a 26" girls huffy mountain bike. I is currently chopped up. I have to wait till she has time to come over so I can customize it to her. In stock form it was way to tall for her.
She has cut the top of the seat tube down. I was so proud of her for holding that torch. She was terrified of it, but she did it. I love to see a little lady out shine the boys. She will need a lot more practice with a cutting torch if she wants to get proficient at it.
I sliced off the top tube and top half of the drop outs. I believe I have it close enough, but don't know until I can measure her or have her next to the frame. It will be getting a handmade customized seat, with laser engraved etching ( done by yours truly), custom rims, maybe a slight rake on the forks ( maybe springers, maybe, not trying to go broke building a bike for her, lol), thumb throttle, speedo, and whatever customizations she wants.
I went with 4 stroke, merely because she is afraid of my bikes ( all smokers). She is completely terrified of them. Now most of us would just be like, " sweet, your MB can pop a wheelie." She's also never been on a motorcycle, I am going to change that next year. She will be getting on back and going for a Sunday jaunt.
My only stipulation for me paying for all of this ( I've offered this to all my friends male kids, none accepted) she has to help build it while I teach her all the tools.
When my pig goes to bed, I'll get some pics of the engine and bike up.
