I have a couple 110cc atvs that my mother in law bought for my kids awhile back, now they dont use them. Thought about making a project out of them. Anyone know somewhere, if there is anywhere, to buy "aftermarket" parts for them? I know they're all low quality being off brand, but I would like to at least widen and stretch them a bit. Better tires maybe? Bigger carb, new piston, etc. Just a small build on them. I know nothing about off brand, anyone have any info for me?

 

What is the point? If the kids don't want to use them are they any more likely to after you modify them? You can usually tune the Chinese Honda Cub clone engines quite a bit, "pit bike" tuning parts are available for them, but the engine will be more stressed and less reliable. Finding normal A arms etc, is almost impossible for "no name" bikes, there won't be anyone making modified ones for them.
