How much hp is your 400EX producing?
#1
After checking out CT's web site I noticed they had a 505EX. What kind of hp is this motor turning? I've got a IMS440, 12:1 JE, port, XR400 cam, hard-rockers, XR250 cdi, full DMC, no snorkle, 6-1" uni-vents w/stock filter, 45 pilot, 175 main, all else stock and I'm figuring 37-40 ponies. How much more can I squeeze out of this motor? Is a 60 hp EX possible naturally aspirated?

You are not producing enpough jay!! J/K.. I got some mods on the Raptor. Nothing to help performance. I ordered a Durablue Banshee 3+5 axle and they sent me the Wrong one. They were cool about it and is sending UPS to pick it up and They are gonna ship me the right one. Only one problem, its on backorder. My parents bought my bro a new YZ80. It is sweet!!! So I am goin to sell the 400ex I think. My g/f is gonna talk to her dad to buy it. How you like theDMC. email me sometime. I dont know yours. Mine is Papapumpdx@aol.com. You are porbally at st.joe right now.
