Replaced my FCR-MX pilot jet with a new Keihin pj and the last couple turns started to have some resistance before it seated, not a lot, but enough to make me wonder. I took it back out and looked it over (looked fine), screwed in the old PJ and it went in fine, no resistance till seated as usual . I don't want to damage my carb. Should I use the jet or order another one? I know I should just get another pj but have a ride planned and wouldn't get it in time. Anybody else run into this ?
