Ok guys, I'm about to start putting everything back together. My question is about jetting. My quad is now going to have a toomey b1 pipe and silencer. A k&n air filter. Vented air box with snorkel cut off due to the 400ex shock. V force 4 reeds. The cylinder is stage 2 ported. The head is rechambered. It just got a fresh bore, just the next size over stock with a namura piston. Where I live my elevation is 360 feet. Where I ride is about 740 feet. It's just over an hour away. The toomey pipe kit comes with a 310 main jet. My question is do you think I'll still probably have to buy different jets or a jet kit? And if so, where and which ones? Thanks guys
