Curious about "predator" swap in trikes - anyone attempt? Online I've seen a few quads done...

I have an 86 trx 70... and got an Honda gx160 laid in the frame with torque convertor .... kind of fits... but I haven't bolted anything down.

I also wanted to try to out in a go-kart reverse box ..

The motor fits better when the head is to the front, but then the shaft is on the other side and turning the wrong way. I can swap the axle sprocket side, but could also make a jack shaft and bring the drive sprocket to the left side , and then drive the reverse box and drive the axle. This fits ok.. but then the air filter and exhaust kinda sketchy with the stock plastics...... anyhoooo

I might just get a chinese bolt-in for the trx, then thought maybe the gx160 can be put in a roller trike...

Anyone seen it? How do the ebay torque-convertors perform? With the gx style motors in a 110/125 would need to make a subframe below the motor..

ive seen a few of the chinese off brand engine swap that are almost bolt in and go. the piranha 140 makes any little 70/90/110 turn into a wheelie monster. the intake manifolds are the issue depending on the chassis. as for the torque converter maybe someone else has played with those.

I've seen several attempts, it usually involves ruining a perfectly good frame. They can be found in your local classifieds, usually unfinished, usually with a price that matches an unmolested one.

The go-kart type torque converters are bulky, not real sure where you'd put one without having it in the way of your feet. The 50/70 style clone engines are the go-to for a reason, they work. I understand using what you've got on hand, but is it really worth the effort to put a square peg in a round hole?
