GO FAST WITH TILLOTSON TCT MECHANICAL FUEL INJECTION. This is a direct replacement for your Predator 212cc or any Honda 6.5hp clone carburetor

i only found out about this the other day myself.

there was talk of other sizes circa 2016 but no more details still.

looking into them...whilst they start easy and give good low speed performance (no bogging etc) they lack in the high end due to small venturi sizes.

ie, expect more power at low speeds, but dont expect an increase in top speed. the exact opposite actually.

still for $40 (more like AU$140 after the exchange rate and shipping...) it could be worth a try...i wanna see how one deals with turbocharging...

Great info,thank you! I already welded up a straight pipe,and had no power/speed increase from it. I’ll try a 22mm carb like you suggested. Maybe that and the pipe together will give me a tad more. I’d love to see a 212cc predator engine on one of these Phatmoto bikes instead of that 79cc Lifan engine. I just want to see somebody do it first so I have something to follow along to.
Is the predator 212cc engine base the same size as the original Rover engine

Drain the engine oil and remove the side case gently so you don’t ruin the gasket. I lightly tapped my side case with a rubber mallet and the gasket stayed in tact. Then you have to cut out the plastic governor that you’ll see in the engine. I then used a dremel tool,hammer,and screwdriver to get the gear out of there. Be sure to remove all the debris when your done.

sadly no. there are no aftermarket parts aside from carb, intake, exhaust. you're in the same boat as Predators and other clones in that size but the good news is you can definately supe it up yourself with a little work. Some Honda valve train parts can fit or engine made to accept in the way of valves, springs & rockers. I'd start with looking at GX100 parts and try to get measurements/specs on them before buying. At the point you'd spend $200 on engine upgrades you'd probably be farther ahead to go with a bigger engine or downsize to a high revving 49cc which is lighter and actually has a higher top speed than a 79
Can u send link for exhaust and carb intake ?
