As far as add on parts I am not sure. I do know that if you ride in a dusty area I would recommend cleaning the air filter regularly. I neglected my daughter's for 5-10 rides and she said it was sluggish and slow and this was confirmed by her friends. I cleaned the air filter and she was smiling ear to ear for the rest of the day...Man, what a difference that made.

That same link has some mod parts

After market ETON parts

I am not an expert in this area but an after market air filter and possibly and exhaust. I heard a lot of complaints about the quality of the air filter but if you maintain it and keep it clean it seems to go alright.

Make sure you put some of that gas stabilizer in your ATV gas cans. Just had my quad and the 2 etons go to the shop to get the carbs completely cleaned. They sat with bad in the for about a month and that was that. They would not start or anything!

 

The after market headlights were a nice add on. No more racing home to beat the sunset with the kids

 

Thank you.

 

what does the dial do

 

14 year old post, but I would guess at an adjustable rev limiter, seeing as it is a Kids Quad, though some racing CDIs are adjustable for advance/retard of the spark.
