build

started building my drag bike in early september hoping to top 60+ mph in the 1/8 mile. power plant is a vintage hirth 292cc 19hp snojet engine with a comet 94c duster driver and a 10" salsbury driven. gearing is 20t jackshaft to a 54t rear sprocket. don't know what this bike will do?

Been meaning to restore this bike for a while now....so glad the OldMiniBikes build off has finally come.... gonna start working on it tomorrow. I have everything to build this bike except an original throttle assembly and a rear fender, just in case anyone wants to sell me these parts to help with the...

Hey fellas. Here's my entry into the 2017 OldMiniBikes Build Off. It's my '60 or '70s Fox Sprite. I'm not sure what I'll be doing for engine but It definitely will not be factory to the bike so I'm entering the Vintage Open class. Here's he kicker for me. I'm going to try to get it done by working...

Hey guys, i figured id make a thread for my drift kart yerf dog that i entered into the 2017 build contest since i have already done some work and this can potentially go beyond the contest end date so here we go. frame as it was when i picked it up, got it off some kid for 170, was missing...

I build this back in '06.....not quite a mini, but it's a fun ride. The grand kids have taken it over, my fat a$$ can't pedal it anymore. We named it the "ped-chuco", which roughly translated means "mexican muscle car":laugh: I keep thinking I need to motorize this bad boy.........

Just one build for me this year ! Bonanza MX frame .....should be easy ..right ? This is it bare frame, swing arm, shocks and a jack shaft...nothing special. :grind::hammer::hack::weld: Let the fun begin ! Good Luck to all the builders this year !:thumbsup: I"M JUST GLAD TO BE...

First time entering. Build off have 2 entry.....This alt to be fun

Hi guys thought id share where my micro build is at so far! The plan was to make the smallest go kart possible whilst keeping it simple and using cheap second hand parts.. Using a lifan 110 at the moment but really need something electri start! The frame is similar to a bierkiste (beercrate)...

Repainted an old bike, went for multi colored, of course it is lifting and I need to redo. Thinking about just going flat black...you folks like multi colored or one color?

Hello. I'm new to the site, and new to Mini Bikes so work with me here. I have what I believe to be a old Bird Mini Bike that I want to fix up. My intentions are to pull the current motor and put a standard 212cc predator on it. This is my first major project I'm not entirely sure what I'm...

When do the entries open up for the build off?

Not sure about this bike's brand, maybe a Coleman? Just purchased and looking forward to re-building this as a winter project.

I have acquired all of the major parts to start my build, and now need some info about frames sizes. My goal is to essentially clone a 70-74" Rupp bike with the motor cycle style frame, but the problem is I have no sample available for me to examine. Although it won't be a carbon copy, I would...

Needing some room guys....so I'm selling this little roller complete minus the engine. Small frame bike great for kids, rear disc brake, jack shaft, seat, handle bars and throttle...just add your engine and clutch. $400.00 or best offer....and I will box it and ship it on your dime...

I was just wondering if there was going to be a build off this year ... Jan1st is coming fast !!! And I got a bike ear marked for this year if we are having one

Hi guys, recently been thinking about building something up over winter, got an old 125 pit bike engine which id like to make use off, wanting this to be a bit of a budget build sourcing second hand parts if possible.. I can make most parts only thing that's stumping me a bit is the rear...

Good morning everybody, long time lurker, first time poster. This weekend I will be building a Predator 212 Hemi for a Motovox MBX10 that was recently given to me, just something to cruise around on. Nothing too extreme. Tomorrow, I'm planning on going to the local shop and buying a Mikumi...

Im looking to build a non hemi predator with RTC-8 head. It's going to be put on a asphalt go kart that will be used for parking lots and maybe on the streets in a subdivision. I would also like to use pump gas. So far I'm thinking: governor removal ARC flywheel 308 cam (102 centerline)...
