Hey all, I'm new to the mini market. My 4yr old is gonna start racin next year and I'm wondering what to do first. Want to wait on bigbore till he's more experienced. What pipe, cam, filter, revbox. Don't want to sink alot cause I'll buy a kit next year. Did a search but most suggestions are for adults. At 4 he dont have a problem with the bars and pegs :roll: . Thanks in advance and great site.
