Shows in the "better pictures" comment. Let me know if the link isn't working.

 

Yeap. You nailed in the picture...much better photo. Now do you know where to refill the gear oil? I think I know but not 100% sure

 

Never had one, so going by what they said. Looks like the plug is just that, a rubber plug. Pull that and I'd use a funnel and some tubing on that to get it into the transmission. Just pour the 8-9 ounces in.

 

thanks for the help with the lubricants and plug locations.
After I got the lubricants changed, I took it for spin and it's making a noise.
As I'm riding it and moving forward it's coming from the rear axle area. I put it up on a jack and put it in forward and gave it gas until the wheels started spinning and that's when it starts. I put it in reverse and it doesn't do it. It's hard for me to pinpoint the noise as I'm up front giving it gas.
any ideas?
BTW it was doing this before the oil change too.

 

The noise sounds like metal grinding or vibrating and it speeds up as the wheels turn faster.

 

Can anyone tell me how slack/play should be on the drive chain. It's a 2016 JetMoto 150cc quad.
