I'm trying to swap out the standard brake and clutch levers on the 1199 for some folding jobbies, but I need to recycle the push pins. How the feck do you get them out? I don't seem to be able to open the lever out enough to clear the round pin base... Sorry... durr...... I am likely to have further newbie questions coming up as I try to strip and track prep my new-to-me 1199; thanks in advance for your patience...!
