I seen online a guy made a crf250jr, i was thinking crf450jx would be the bees knees! If im gonna commit to this build, i wanna go big not goin home! electric start 40+hp and convert to road legal. well at least look legal on paper:) I am an excellent tig weldor and fabricator. curious...how much bigger and heavier is the 450 over the 250 and 150? Im a small guy and miss my old kx100. I want the meanest way too powerful trench digger i can make yet a still functional bike.... And fuel injection would make this little bike about the coolest thing i could think of. The only problem i can foresee would be that for one i would have to offset the motor for sprocket chain alignment and two might have to raise the back bone to clear the swing arm pivot point/ chain slider and valve cover clearance to frame??? What do yall think? Possible?
