I'm new to the Honda world but have a KTM 450 EXC and just sold a KTM 625 SXC. In the KTM world, the Keihin FCR is the hot carb. I see lots of posts on this forum about the Edelbrock , but very little about the Keihin. Why is that? Is anyone running a Keihin pumper carb on the 650R and if so, what do you think about it? Any comparison with the Edlebrock? Any issues installing? Thanks in advance.
