It's kind of no longer a 1000LTD with your mods...great looking bike. Glad you are enjoying it.
It's definitely still an LTD, just a better one. It's still got a stepped seat, the bars aren't as tall as stock but fit me better. It came new with a Kerker(dealer option) and still has a 4 into 1, but the carbs have been replaced and so have the shocks but they are the same length. It has the original bodywork, still has the original 16" rear wheel and the motor is stock.
If I changed to the bigger gas tank, get rid of a front brake, change the headlight and front turn signal mounts, change to spoke wheels, change the rear brake from disc to drum and install the A model banana seat then yeah it's not an LTD anymore.
