If I ever build an electric vehicle it will be 48v 1000w. I've thought of using a moped frame with a high power motor and a ton of SLA brick batteries wired in series and parallel with a balance charger. At 48v 1000w any 2-3 wheeled vehicle is street legal with no registration, insurance, or...

Lifan? Sluggish? Noooonononono... bud. See this 'ere bike? This is my friend TJ's bike. It has no engine mods. He has nearly 2K in this motorized bicycle (motorcycle) build. It's a 125cc, and currently hits 68mph with a semi-auto engine (get a full manual by the way). There is so much torque...

I got a Kasea Adventure buggy for $100 yesterday. The engine has seen better days. The axle is also wrapped in fishing line, the roll cage slightly bent, and there's a sad paint job. I'm not bothering with the engine, I'm going to put an ATV engine with transmission on it. The engine was...

Semi auto gear shift bro. http://www.ebay.com/itm/125CC-SEMI-AUTO-ENGINE-MOTOR-3-SPEED-REVERSE-ATV-QUAD-GO-KART-3-1-P-EN19-BASIC-/251044507292?hash=item3a736b2e9c:g:naEAAOSw7NNUF4Rt&vxp=mtr I'm going to build a kart with one of these soon, but they only do 50-60mph. Which I got with my BSP...

I just modified the intake. It now accepts the 3/8" hose that comes from the valve cover breather tube. I'm going to test this on my 79cc motorbike and see if any oil blocks the tube.

I dropped a predator 212 and broke off the spark plug cap. It is snapped in two. I've been looking around and, people don't sell these things like other parts. What are my options for a new spark plug boot?

So, I test fitted the first model. If I didn't break off that bottom piece it would have fit without the nuts running out of thread... anyway here's some pics. I finished the second model and it's perfect. Fits much nicer too. The second model is in the last two pics.

Even better, a finished one! This took exactly 3 hours to print. I broke off the bottom 1/4" of it by accident (pulling these parts off the print bed can be tough, especially with the flat surface that was printed around it to hold it on during printing). I don't think it will have any trouble...

http://www.thingiverse.com/thing:1832430 I'm printing this today. I find it very interesting, perhaps the plastic may work on a predator. I guess we shall see. I'll be using this filter...

If anyone has a spare hemi predator push rod I really need one and can pay for shipping. I'm about to rebuild an old dingo with a predator 6.5hp. Thank you!

On the 212 hemi, can I block off the breather tube to the valve cover or does it need a small air filter? Because I'm taking the stock air cleaner box off. Thanks

It's coming along...

So, I'm about to build a motorized bike. (Most of you are probably already familiar with these, but I ramble about them below anyway) I've ordered an 80cc two stroke kit, and I have an old Trek mountain bike ready to convert. These kits are awesome. You can find them on ebay for $99, and they...

Was browsing on some buggy forums, and they have a good solution for putting speedos on. Since the wheels have suspension and they're moving all over the place, it can be hard for the speedo to work right. So... They put the magnet for the speedo on the axle sprocket! I think it's a pretty good...

Hellion, my trophy please. Lol So. Stock billet rod exploded. Left a hole in the block. My options are: 1. Buy are billet rod, weld block shut. Say nothing ever happened, race on. 2. Sell engine parts. Buy a motorcycle engine off of Craigslist. Go fast. This kart was in Craigslist, due to it...

Well, guess I was right. It blew up. DANG YOU FREAKING ENGINE Edit, took off valve cover. Both rockers are fine, left side pushrod is loose.
