I am having some issues installing this 41 mm FCR carburetor from Keihin. Originally when I ordered it 2 months ago it was supposed to be a direct fit plug and play. Come to find out I have to tap my thumb throttle housing so the new cable works.or get a honda set up. had to modify the airbox blah blah blah just wondering if anybody has any insight insight with this carburetor on this bike . It seems like the intake Isolator boot won't allow the carburetor to slide all the way in. Got this carb because I put a lot of time and money into it. . Athena 440 bbk stage 1 hotcams.full hmf pipe. List goes on and on . I've rebuilt the oem carb jetted it up and down and it just didn't seam to get the job done it needs to. Any help would be highly appreciated. Still fairly new to the site. I have tried to post this a few times. I don't think it went thru . If it did I am sorry for the additional posts for the same thing.
