Just bought a honda 3 wheeler and it smokes a little bit what should i do?

So i was thinking i just need to keep oil in it and it should be fine but i'm not totally sure. The smoke is either white or blue. My problem is i had a arctic cat 366 that did that and the motor blew. So what yall think i should do?

Along with Freddy's answer, if this is the case and you forget to put oil in it while riding and it burns it all, your motor is screwed and it will be blown up just lime your arctic cat

2-stroke or 4?

Always state Make, Model and Year for better answers.

If it's smoking and the smoke is white or blue it's piston rings are probably stuck together and it's allowing oil to pass into the combustion chamber where it's getting burned along with the gas therefore causing the white/blue smoke. You should check and if that's the case then just replace the piston rings… That's how it works with a four stroke anyways.

PS: If that's the cast then you will never finish putting oil in it cause it will just burn it all.
