build

Got some parts in. Engine, tires, brake caliper and such. I'll get started once I finish cleaning out and rearranging my crappy little shop. I'm going to make an aluminium engine mount with maybe 10° tilt and integrated jackshaft. May not tilt if I can clear the TC driven without it. Got my old...

Hey folks. I'm in need of a HS50 slant intake manifold for my 1971 MTD mini bike build. It's the last part I need to complete this build. Please let me know what you've got and I really appreciate it. Cheers:thumbsup: Scott

Hello, I just got into the world of mini bikes and I just started the modding process on my little beast. I have a few small things done to it, but I want to use it as a test platform for engine work and continue to ride the crap out of it....I could use some input here soon on matching a cam...

A lot of times we make progress on our builds but it's not enough to put in our build threads or you don't think it will be meaningful for others to read about. Well that's where this thread comes in handy because the little things we do really add up if we make continuous progress. Consistency...

Howdy, every few years in between building hot rods I build a new toy and this time a Drift Trike. I had never seen one in person but had watched them on youtube and decided to give it a go. My last post was a mini bike project several years ago, and I still enjoy riding it. A link to it...

Here we go again with this motor . She was originally build for the super Powell had a CL1 cam billet rod and flywheel, head was ported and mill 80 thou , pretty much just stock . This motor was bought back in 2011 it was run for 10 min and never run again till last year . What I've found out...

Mods feel free to move to the more than 2 wheels section if that is more appropriate but as an active build I thought this seemed a more fitting place. After determining my Snow Bike build wasn't for me and not having any luck selling it I've decided to use parts off it to build a drift trike...

One of my students build off bikes has an engine that needs parts. Instead of spending hours trying to find everything and buying the wrong stuff I thought maybe all you could help me. Here is the info I can provide. The engine came off of a Trail Horse, it is a 2.5 hp. I believe it is a...

I have to mount the front fender, and put some finishing touches on it. Next weekend my son and I will be entering it in a local vintage mini-bike and moped show. Can someone tell me how to upload pictures to a thread?

I bought a Doodlebug, bought a Predator 212, got the install kit, and put it all together grinning from ear to ear. Fired that baby up and let her warm up a bit, jumped on, gave her some gas and the vibration taking off is horrible! After the clutch full engages it's just fine but taking...

New member to the forum, and first time ever joining a forum! I debated joining for a while because I don't actually have an old mini bike *yet* (well I guess mine will be old someday), I just have a predator swapped Monster Moto. But this forum has helped me out in the past so I figured maybe I...

This is my current work in progress. It is a reverse trike with independent single A arm front suspension. I am using a Predator 212 with TAV2 and a 15 inch diameter lug tire for improved traction since there is only one drive wheel. It rides fairly smooth however, with no rear shocks it can...

So I am looking at doing my first mini bike build. I don't really have a budget but the more it cost the longer it will take me to build. Looking for something fun. I have never owned a mini bike before and just want a new hobby. I like building motors and my current project, my 4X4 truck is not...

Good evening everyone, if you didnt know I love flatheads, and I know you guys will enjoy my latest project, originally I wanted a stock appearing Raptor to beat an animal bird, i had a bored stock carb and obtained my goal, this year i figured we could let the beast breathe, only missing two...

This bike belongs to the tall kid with the curly haired kid. Many of the kids at work.
