The CT dyno for their 240 kit shows 40 rwhp at midrange rpm, then falls on top. I'm assuming this kit is everything though to get it to that hp, port job, better piston, more compression, bigger carb, exhaust filter etc etc etc everything

But yeah, if those numbers are accurate, it would smoke a 400EX no problem, even a piped and filtered one. a stock 400ex runs 27hp

 

the hollywood dirt blaster puts out over 40 hp to the ground and will spank a 400ex and a banshee, no problem, no compitition

 

well anyway thats stock vs. heavily modded put a sparks or kenz 440 kit on a 400ex or even a sparks 465 kit and see what happens to that 240 blaster

 

ya but 300ex won! not by much it might not even be a win cause 400ex and my 300 were side by side hole time.its a vitos 240 kit for blaster
