This is my bike i swore i wouldn't motorize it but after much thought and harassment from friends i caved. But instead of going electric or one of them 2 stroke putt putts i chose a predator 79cc 4 stroke. The motor came with a gokart clutch and jackshaft plate but i wasnt happy with the clutch as it was very sluggish and seemed to need to many rpms to get up to a decent speed with my fat ass on the bike. So i upgraded to a comet 30 ctv torque setup with a chain driving the rear wheel. Turns...
 
Still my same bike but my first thread is so old and it's come quite a ways since I first put it together, so I wanted to start over with a clean fresh new thread. Here's my current build, based on a 1997 Gary Fisher Mamba. Here's how she used to look: And here's what started the change: After this happened, one thing led to another, and, well...here she is. PARTS LIST: Engine -66cc China Girl --No-name billet head --No-name MZ65 replica --DIO reed valve --19mm OKO carburetor...
 
Is the new build this one will be much better am determined
 
Just a temporary build. Minarelli hybrid with Athena Sport 70 top end. It's fast running just over 60 mph on 10/36 with 27" tires (26x2.5 Hookworms are about 27.25" tall). Swapping the vm20 for a Tilloston clone when the return springs get here. Not my favorite bike lol.
 
Hey guys.. Been a member here for a little while, have done mostly reading and not a lot of posting, but i figured i'd join this section and post a picture of my bike! I built it in the spring of 2017. The bike is a Genesis GX7, 7 speed with 29 inch tires, purchased from walmart.com. The engine is a Huasheng 49cc, which came with a kit from gasbike.net, but once i learned the transmission was complete crap, i immediately upgraded to the Q-matic from the EZMotorbike company. 60 tooth...
 
2ND BUILD BUT HAVING TROUBLE WITH STARTING MOTOR! NO SPARK
 
Just got this new addition to the harem. Like new Phantom Gray Ghost. Dude had it left to him. He couldn't get it to run right. Took it to a lawn mower shop and they told him it had a flat cam. Sounded like a carb issue to me. He wanted 1100 but since he couldn't get it to run he dropped to 650. I offered 500 and he took it. Swapped the stock carb for a NT and it runs like aq top. So anyone know where I can find brake shoes for this hub?
I started 1 of my new bike builds yesterday. I should be riding again by this weekend. (y)(y).

Well it’s built, first 1400 takes it. This is my new job I’m not going to sell something that is not legit.
 
I still have a few things to do but so far it is going fast. Thought I would show it off well doing maintenance What do you guys think would look good on it? And yes it will be cleaned soon

thanks for all your help with this forum helped a lot with my bike build
I just finished my first build. I ran into some road blocks but here is the fruit of my labor. I haven’t been able to start it yet because of the temperature outside being sub 0 for a few days. I have a brake cable that was directly underneath the gas tank so I sheathed it with some firm aquarium tubing. It seems to be fine Imgur link with photo

Has anyone tried an experimental method with ram air
 
Been working on this bike for a little while now put in a bent springer fork I didn’t want to cut threaded forks so I added some spacers and a shorter BMX stem really loLowered And I installed some really tall ape hangers I’ve been trying to strip off the old paint And been restoring small parts here and there Some engine work too but not ready for an install
