Every thing installed easy, no problems there. It was very lean from the factory and took many clicks (around-6) to keep it from popping when I back off of the throttle at high RPM. It was an easy adjustment since I left the needle adjuster on when I installed the carb. I was able to adjust the needle with out even taking the gas tank of or even loosening it. It was a very tight squeeze but sped things up. I payed the big bucks for this mod because I'm only 5'07'' (yea, after hanging by my feet for an hour). It has all ways been a major pain to balance the BRP and go through starting ritual "MANY TIMES" after a crash on an uneven trail, or even a flat surface when the pig is extra flooded. I just wanted the beast to start easier! Any way, I heard that I shouldn't expect much in performance, only a better starting bike. What a difference the carb made in preformace! My bottom and mid is waaay stronger. I have to be carefull when grabbing second on the street or the front end starts skyward. Just like everyone has claimed, no more hesitation off idle and it does start a lot easier. I tested it by laying it on it's side. It kept running and didn't spill a drop of fuel. It kind scared me, I'm not used to seeing the pig run for any length of time while on it's side, it was like having a wounded animal in my driveway, hahaha. I couldn't take seeing the beast like that for too long so I killed the engine. I was prepaired to have to kick it a hundred times or resort to my bag of BRP starting tricks. It started after the second kick! Very impressive. I have heard that the stock carb can be very effective if dialed in right and that the only major draw back is it's starting issues. If that's the case my stock carb must have been way out of whack because the Edelbrock made a BIG difference. BTW, my bike has all of the basic mods to include the Al Bakers gold series pipe. It was re-jetted and tuned by Al's crew. They left it a little lean, it started to pop a little after several rides. Sorry Al but I'm a Barnum fan now. I am getting some bogging toward the end of the RPM range. I haven't noticed this problem before. It just might be the rev-limiter kicking in. It's still pretty strong up untill this point. I think that with the old carb I normally backed off just before the rev-limiter hit due to a flat spot at very high RPM. I'll have to play with it some more to figure it out. If it's not the rev limiter it should be easy adjustment with this carb. Like many others have said, "I SHOULD HAVE BOUGHT THIS CARB A LOOOOOOOONG TIME AGO!
