I'm trying to disassemble this frankenbike for parts.
It's an old Lotus, but the previous owner swapped out the original Tange fork for a longer Reynolds 753. He also put on an aheadset, and as you can see in the picture, there are still some threads exposed.
I am desperately trying to get the stem and handlebars off, but loosening the bolt on the stem wont release it. I don't have experience with aheadsets. My first instinct was PB Blast and twisting it out, but so far I haven't had any luck. I figured I would come here for advice before making a serious mistake.
If you have any idea what I should do, please let me know! Thanks so much.
