Hi, I'm going through my 81' Interstate this year. I've never had it on the road except to ride it home.I looked at Progressive's site for new springs and I saw cartridge emulaters. Has anyone used them and does it make a difference? I'm going to put springs and seals in the forks and figure the time to add the emulater would be at the same time. Next question; I just finished cleaning and rebuilding my carbs using Randakks kit. On the last carb I cleaned the idle jet was plugged solid and cleaner and air wouldn't clean it. Ended up using Littlebeaver's method of pulling it with an easyout so I could clean it. Fortunately it worked. I did check the other carb passages when I cleaned them and they all passed fluid thru the idle jet circuit. Now I'm wondering if I should go back and pull the other 3 idlejets so they can be cleaned as thoroughly as the one I had to pull before I put the rack on the bike. Your insights and opinions on this are greatly appreciated, Steve.
