I got some drone footage of our TW450 in the ice and snow today.

We've had the Predator 459cc on our American Landmaster TW450 for about one month now. And I've got to say, this has been a solid motor! My kids have really put the motor and the whole side-by-side to the test. But it's running great! The original motor was a Kohler ECH440 with 14hp. We've had ice and snow all weekend. But we can feel the extra power with the Predator 459cc (15.8hp). Just wanted to let y'all know, if you're looking for something to replace your motor on the TW450... We considered the cheaper Predator 420. But I'm really glad we got the 459!

We've got a simple "battery-to-solenoid" connection to use the electric start on the Predator motor. But what I really need help with now is figuring out how to get the headlights and maybe even the stock ignition back working again. Does anyone know how to get an after-market motor connected to the stock wiring for ignition, lights, acc, etc.? The little copper solenoid terminals on the predator already have several things connected to it. Any wiring advice would be greatly appreciated! Thank y'all!

GREAT news, y'all! The new HF Predator 459 was successfully installed and runs great! Even wired up the electric start.

An update: The throttle cable we bought on Amazon was a perfect replacement with plenty of extra length to ensure we had enough. We installed it to mark where to cut the housing. Then pulled the cable out of the way to cut the housing only. They pushed the cable back thru and cut that separate. Works great and awesome to have the TW450 back out in the yard!

We've got the old Kohler motor out and the new Predator 459cc in! But before we put the motor in there. I took some pics of the old wires. I'm hoping y'all can help me figure out what all these are for and what we need to keep. There are a lot of inline fuses. And all the labels we can read say "12v pos" or "regulator/rectifier." Main thing I'm looking for: 1. Wires to connect the stock ignition to the starter on the new motor 2. Wires for the headlights If anyone can help me identify what all these wires are for, I'd appreciate the help!

I found a 70" long throttle cable with the eyelet on one end and open on the other. $10 on Amazon and it'll be here tomorrow.

Here's what we hoped to install tonight. ;(

We bought a used American Landmaster TW450 with a Fuel Injected Kohler 440 on it. Today, I bought a Predator 459cc 15.8hp motor from Harbor Freight. But before we put the new motor in, it's pretty obvious, the stock throttle length is NOT long enough. The stock throttle cable from gas pedal to the end is only 32 inches! We need at least another 10-12 inches to get to the throttle linkage on the new motor. What can we do?? Is there some way to modify the original throttle to add some length? Or do we have to buy a brand new cable?

So today, I bought the Harbor Freight, Predator 459cc 15.8hp motor to put on our Trailmaster TW450. Same shaft diameter and length, a little more HP. Hoping to have this thing running again soon! If y'all have any tips/tricks/advice on how to proceed with this motor swap, I'd greatly appreciate it! Especially if y'all know of an easy way to get the stock ignition to work with the starter on this predator motor, that would be awesome!

Well, my son pulled the motor and took it apart the other day. Now we can see exactly what's going on inside the original motor, Kohler ECH440. Might not be able to tell exactly what happened. But definitely appears beyond repair!

Y'all may remember, last year, I had some big problems with our Landmaster TW450...

A new belt fixed our weird lag issues. The kids ran the go kart all day yesterday, no problem. Then it started doing this... Any idea what would cause the clutch to grab so aggressively like that??

When the kids hit the gas, I can see the front clutch pulley trying to engage the belt. But all it does is burn up the belt. I have ordered some new belts on Amazon that will be here in a couple days. But what else could be going on that the belt is not properly engaging? There's no WD40 or any grease on it. Only difference is I tried riding it (290 lbs).
