Talk to Carlos, remove one plate, replace with what he says, its lil bit thicker on that 1 plate. Cant remember egg zackly.....
I have a snotty ported stock cylinder, raced 300ft for 2-3 yrs, works great for me.
It pays(saves) dearly to shop around, there are better products out there than what you can order from dennis kirk or RM ATV... IMO only.
Need help w anything, PM me,
