Replacing the engine in a Baja 90cc Kids ATV with a 6.5HP GX200 clone engine with a comet Tav2 30 Torque converter.

This quad has been just basically sitting around collecting dust for the last couple years and I also had a 6.5hp clone engine, from an old pressure washer, that I haven't touched in about 10 years. I had some free time so decided to see if I could pump some new life into this old 4 wheeler.

The stock engine on these is an 86cc 6.3HP engine with a centrifugal clutch, and it's pretty gutless since it is made for kids. It is also only electric start which is annoying when you want to use it and the battery is dead from sitting too long.

The new engine I put in is a 196cc 6.5HP engine (that is at 3600rpm though, once you bypass or remove the governor they probably run around 45005000rpm and probably put out around 7.5HP). On top of that I put on a torque converter clutch which gives way better performance then just a regular centrifugal clutch. Also no electronics so never have to worry about a dead battery again!

Overall the engine swap works well with way more performance then the stock ATV.
