Does anyone on here have a LTZ 400 with a 500cc big bore stroker kit. If so post your hp and your mods:cool: :cool:

I have a Four stroke tech 500 bb/stroker in my dvx. I never put it on a dyno, but it flies when it is jetted right. I have high comp piston, race cams, valvesprings, stiffer clutch springs, porting, cdi, full exhaust, 400ex air boot and k&n filter, aluminum air box, and edlebrock carb. The one problem I have is that the crankshaft is overstroked. Caused lots of problems until we realized that another base gasket was needed to fix the problem because fst didn't want to fix it. Pistons need replaced once a year at least and you have to watch out for the thin cylinder cracking at the bottom due to more side force from the increased rod angle and extra piston travel. I will be taking the messed up crank out to reduce problems so it will only be a 470. Oh well, it is only the spare bike now.
