I am getting ready to build a big bore 250r motor out of a 250r crate motor. I have been looking into a couple of different kits. If anyone has one of these kits, let me know how you like it. The kits are the PSI 425, CT350 or a CT330. I am waiting something that will contend with a Raptor and a 420 Banshee. Thanks for any help!

 

I have had the ct 330 and now have the ct 350 and this thing rips, torque like crazy. I run blacktop roads, 6th gear wide open against banshee and the ct 350 is hard for a banshee to beat, unless worked pretty good. what do you use the bike for, what style of ridind

 

I use it for mx, play riding and a little bit of duning. Can you tell a big difference between the 330 and the 350? Thanks!

 

have you had any problams with your kits? do they ever over heat? i bet that is one fast bike did you think about getting power valves?
