Pretty new to the posting, so give me a break. I have a 2000 YZ426, I want to it's Keihin 39mm(w/ removable intake bell) on my 2006 Suzuki DRZ400sm. I was going to replace the carb w/ a newer Keihin that doesn't have a removable intake bell. I also have a 2005 YZ450 I was going to "borrow" a carb from to check but I figured I would ask to save me any headaches. Any info would be appreciated.
