    85 250R frame specs or pics

    Does anyone have any frame dimensions or specs for the 85 R? Im getting ready to rebuild mine and want to make sure its a good straight frame to start with. Anyone have a pic from the front showing the alignment of the front neck and down tubes? Thanks!

    As stated, straight edge, level over rear top sub-frame while keeping bottom of frame flat on a good table or surface. This will allow you to quickly eyeball any warps or twists. You can also use string to measure twists by measuring triangular points on Left to right and comparing equal frame points & distances.

    Other methods get into special equipment & complexities.

    So, i guess i should have started with this...... is the frame symmetrical then? The center of the steering neck should be the center line of the whole frame? Everything equal distance, square and mirrored from that? If i were to cut the frame down the center the two halves would be the same?
