Got the FCR from an 03 E model put on my 06SM. Thanks kvo for that one. Installed with jetting instructions from Eddie. Used all new factory parts to install this on my bike.(including new E cables) Bike runs and idles and starts flawlessly. It rides so well. No bogging or hesitation what so ever. Well at least up to 70mph. I would not say it will rotate the earth but the power is def better. No where near a power wheelie in second but I am pleased as punch:crazy: Now onto my problems. Bike rode awesome but then after about 10 miles or so the throttle started to hang or stick a bit off idle. Then when I got home I could watch the linkage and throttle wheel. If I wacked the throttle I could feel an initial hang up and then the throttle would stay high. On the way back down I could watch the throttle wheel winding it's way back down. Gonna have to let it cool and look at it again. Do these e model carbs have a sticking issue? I found nothing on a search. Next problem is the gas tank and petcock. The damn thing is a mother trucker to get passed the TPS and choke putting the tank back on. Once it is on the choke can't be pulled out as it hits the petcock. I was riding on prime so if there is a smaller petcock out there I am all ears. I heard somethign about a WR yamaha unit. Bottom line, had fun working on the bike today and just need to get this throttle binding figured out and then it's now time. PS, this carb exhibits no tendancies to stall ever. I can whack the throttle all day long riding or off the bike and it is smooth as glass and holy mother of throttle response. Sorry for all my jibberish.
