Could be a Kill switch,usually blk/wh wire, & on handlebar brake,tether switch,brake pedal, remote box, Try unlugging the kill wire from the CDI first & if it starts that means you have a kill switch on
Again, if it starts you cannot turn it off with the key etc...
.Then unplug remote box - try to start - you will have to kill it by choke or remove plug cap though, at least that will tell you if that is what is wrong.
Otherwise, it could be your ign switch, if it got wet, CDI,coil, battery.

Vin number location for a roketa 400 atv
No its Chinese made.
85b00692
The spark plug is located on the top of the engine. I have not yet found out how to really get to it since it is in there at such an odd angle but, it is there.
It's to control a fire hazard in case of an errant spark, so possibly a melt down of your ATV
Yes, roketa is a great brand for fourwheelers and scooters.
spark gap is 0.28mm.
Replace coil
Not all atv's have them.
.028
The spark plug gap for this kind of ATV is .035.
clean the carb,it must have some trash in it and check the spark plug it may need changing
