It's been quite a while since I've posted anything. This is one of my latest builds, top speed 55mph.

How's it going guys this time I took two other projects apart to make this one. I have a question about torque converter. My current gearing is a 14 tooth and a 48 tooth on the rear 24-in wheel. The torque converter has a hard time getting past 42 mph. With a centrifugal clutch that current...

All right, where to start. LOL I bought a 40 series for my 420 predator. The plate was strong enough but somebody welded the back pipe with bearings crooked. I cut the plate almost in half and bend it at the seam and rewelded it to get the pulleys to line up. Then I noticed if I kept the rear...

Im thinking about installing a gy6 150 on my trike but i cant any pics online showing the final chain drive up to the engine. Is it just a splined pipe with a small sprocket attached to it hanging off the shaft where the original scooter tire fit? Is the output shaft supported on the other side...

My latest 420cc project. Street legal of course. Od green and tan. I definitely need to get a smaller sprocket on the back to get some more speed out of her. Could use a speedometer also, and I will be building a front fender for it soon.

I was looking around at various types of equipment motors to install on projects and came across a few diesel motors. Does anybody on this forum currently use a small equipment diesel motor on their mini bike go kart or other vehicle? And if yes what size, how is the reliability and what is the...

How's it going guys, just wanted to show you what I've been up to lately. I lost count and how many versions of these I've built. However I believe this one too be the best yet. Even though I say that about every other build 🤔 Current gearing allows for almost 60mph, I'm going to hop up the...

What aftermarket cams have you guys installed on your predator 420? Which ones have been the most reliable? And which one seems to provide best overall performance?

Just wanted to show you guys my newly-completed 670 project. This is version 2.0 of an existing trike I had they had a 250 Ninja motor in it. I only have a few miles on the trike right now but so far I am pleased with the 670 power so far. I am not new to Predator Motors but I have never owned a...

What happens if you use a motor with more horsepower than the clutch is rated? What would be in Jeopardy of failing?

How do i upload a youtube video in a thread??

Haven't put too many miles on it yet, Finished electrical and paint for the most part everything seems to be in good working order.

First you cut out the shape you want in wood. Then drill and drop two bolts in of your choosing for the seat mount. Now you don't want the bolts to rotate under the foam and fabric, so I usually weld a thin rod between them. Next I usually start with the blue camping pad from Walmart as my base...

It's been my experience when using the 420 predator that the charging system sucks. Since I build street legal motorcycles with this engine I'm limited with how much power I can draw from the main battery. I figured a simple way to power the main headlight is to use a rechargeable battery that's...

Do anyone of you have experience using this clutch? It is a outboard only, 1in bore that tapers down and uses needle bearings instead of a bronze bushing. It's a ten tooth also.

What's up guys, just wanted to show you my latest Predator project. Just ordered a few more things for it little bit of fabrication left. She will have a 420, with a 24 inch tire 10 tooth clutch and a 70 tooth rear sprocket. She should do 55 plus, last time I learned my lesson I'm not going to...

I want to get a thin lightweight billet flywheel for my 212. What will be the benefits of this mod, if any? Will it affect idle at all? Will it affect pull starting? Thanks

Finally got my plate. Been dragging tail to finish. Motor still needs mods done to it but in good time I suppose. Here's some pics for ya.

Hi from vegas. Been awhile since my last build. It's in the process of being finished, hopefully by my next days off. I still need to modify the motor, finish some welds and paint also some wiring. Then it's off to the dmv to get a plate. Let me know what you think!

Hey guys, wanted to show you some billet destruction. This happened while slowing down to get into the turn lane on my motorcycle. And no, it was not due to lack of oil. Bolt failure is suspected at this point. I didn't know you could break one of these!? 420cc predator aftermarket rod not the...
