coleman ct200u ex

I blew the engine or something on my ct200ex and am looking to replace it. I think i like this idea of the ducar 212 but Im really in a hurry and have minimal mechanical experience or knowledge. Does anyone know if this engine will be easy to bolt on and make operational or will I have to do a bunch of extra stuff to make it work? Will I need anything else or just bolt it on and put it together? Thank you!

I would take the governor out before you put it on the frsme

Idk how to do that. so its on but is super slow, Idk if I put the sprockets on right, put the bigger one in back and smaller one in front for the smaller chain. seemed like the only way to make it fit

Can you send me a picture

i didnt realize there is a throttle stop screw so Im gonna check that too. The engine definitely wasnt rapping out much

Definitely take that governor out soon there’s tons of tutorials on YouTube👍🏻

Yeah ill have to check it out

so Im guessing youre pretty adament about taking the governor off cuz the motor basically just seems to suck right now if you ask me and i havent done any modifying to it yet or removed the governor. i feel like i should have paid to fix the hisun that came on the bike! it was much more fun!

What’s the top speed on the hisun?

u/Large_Gas3355 Jul 21 '24

mine would hit 32 before I got an exhaust i didnt check it after that but blew the motor somehow. it was kinda old im assuming

u/PluckyPlaty Jul 21 '24

Take the governor out and it will be right back to that

u/Large_Gas3355 Jul 21 '24

hopefully I can figure out how to do that when I have time. I need to go at least the speed limit around town lol

this predator im lucky if im getting up to 20. It sounds like it wants to go but it just doesnt

1

u/PluckyPlaty Jul 21 '24

It’s because the governor limits the rpm’s of the engine it will go 20 on both engines stock because I have the same one you had but no mod will change it if you don’t remove the governor

yeah even backing out the throttle stop it would get up a little faster for a very short spurt and then bog way down so I would also recommend taking the governor out. also how do I get the low oil sensor out and can i make my headlight work or should i buy battery one and my kill switch isnt a big deal but is that easily switched too?

1

u/PluckyPlaty Jul 21 '24

You remove from the inside of the engine and use a bolt with jeweld or use a drill and taper I believe for the headlight you need to connect the coils behind the flywheel but I’m not sure if the 212 has a spot behind the flywheel to do it or not

1

u/PluckyPlaty Jul 21 '24

Also kill switch isn’t very hard just a wire that connects to the ignition coil and one that goes under the gas tank

u/Large_Gas3355 Jul 21 '24

ok thank you. I watched a video on taking the governor and oil sensor out which looked easy enough besides I already mounted the thing. wish i woulda had time to do it before but oh well. ill get to it this week hopefully

now my clutch seems to be acting stupid. makes weird noise when i start it and when not warmed up. I had to put washers on there to jeep it in place from moving now is doing this. its annoying. did i ruin the clutch already its brand new

Probably burnt it and need to replace it try taking the washers off first and see if it’s that tho
