Best place online to buy upgrades for small engines

[Jackseale777]

I have two Duromax 18hp engines and I'm looking for air filters that connect directly to the carb or maybe a good pod filter, jet kits, and I am stumped on finding some. I'd like to have an assortment jet kit so I could try out some and test them. Thanks guys.

Check out Vegas Carts.

I have a duromax 7 hp most of my parts have come from NR racing or OMB warehouse; customer service is good at both; that being said, some of my parts have needed modifying or didn't just bolt up requiring other parts to make them work ,so take careful measurements and ask questions concerning part compatibility. I try to buy parts in bunches to minimize shipping cost.
As for the motor itself I love it ,stock with cc it's faster down low than either predator 212 or 420.( both of them have t.c.'s)

I know you asked for "BEST"
But here is a long list of Kart Parts places:

Do y'all think that the 212cc predator exhaust and air filter kits will bolt up to the Duromax? I'm not home at the moment to do measurements.
