    that is true and is really nice if you dont plan on having a major project but if your already going to have it apart and feel like doing it anyways you can get that horsepower at the wheels. all depends on how much money you feel like spending.

    Thanks guys really appreciate the advice!!! I'm going to definatly take the motor down and put lifters in and probably the 1050 kit I think. Don't really feel like getting into cams and timing and all that stuff. I am very mechanically inclined and can do it just don't feel like having that much of a project (only trying for weekend tear down and back together). Do I need to re map my ecu? The ecu in my bike is stamped race use only. I assume that's the premapped ebr ecu. Probably a good question for whoever I buy the kit from but midaswell ask. Also since it needs a lifter do you all suggest factory lifters or any aftermarket ones?

    I would get aftermarket lifters, and the ECM will have to be remapped since it is for a 984cc instead of a 1050cc which will need more fuel and air

    Make sure the cam isn't hurt...if it lost an alignment and spun in its bore, it probably took the cam with it...hopefully not, but...!!

    most of a power increase would be from cams and heads. the bikes now have a nice epa rated cam in it and really can change with new cams and especially the heads. you would get way more power out of the cams and even only stage one heads than a big bore kit. going from 984 to 1050 is only a 6% increase in displacment and really wont give you to much more power. if your looking for a quick power increase heads are where you would want to go.

    Besides the 6% increase in displacement though it also up's the compression ratio a hair, that's probably where more of the power increase comes from. At least that's how it is with the blast big bore kit, which only goes from 492 to 515cc but increases power substantially. I've been looking and can't find one, but does anyone know of a video on youtube of someone showing how to do a 1050 kit install? I want to get one for my bike eventually but I've never done work on the internals of an engine. Do companies like nhrs, revperformance, hammer performance, etc, send good detailed instructions with their kits or do they just mail you the part and wish you the best of luck?
