hey,
i want to know cheap mods for my mojave. i will later on put shocks on. but i was looking at the four stroke tech Black Box mod. i would like to know where to purchas stronder valve spring. i would like to get an exhaust. what is the cheapest?where can i fined this exhaust? where is the cheapest sight for a slip on supertrapp. thanx.

 

i would like to know if i would need stronger valve spring if i were to put the black box mod on? do i need to rejet if i get a slip on exhaust? thanxs so much yoiu guys rock

 

Don't know if you need stiffer valve springs with the black box mod. The company that sells it should be able to tell you. As for the exhaust, some require new jetting and others don't. The DynoJet kit will cover you either way but some guys feel it is a rip off. I've got one and it increase my power and response so even though it was like $50 I thought it was worth it.

 

as far as exhaust youll be one loud mo fo but the cobra steel is a straight pipe and is like 89bucks and makes about 1 1/2 to 3 hp? with the rejet and you will prob want a clamp on filter they are cheap and flow good so theres another 5hp with a k&n
