Big thanks to Steve (xcuvator) for dragging his carbureted 610 over today for some install and testing. We tried once before with good results but needed some fine tuning. The carb size wise drops right on where the stock carb was, zero issues and looks small in comparison to the FCR it replaces. We also changed out the throttle to the single pull and new cable. Cable was way to long but works and is being addressed. Steve has a lot of extras on his bike so the install took longer than usual as we had to pull the big tank with 5, yes 5 hoses off, hand guards, all sorts of goodies. That said the actual carb install was super simple. Slapped it all back together, hit the starter button and boom, she lights right off. Adjusted the idle and took it for a ride. Runs great. smooth and snappy, no bog, idles well. We were getting some black smoke cracking the throttle while just sitting there so we leaned the rod out some. It took care of this but I think we went to far and it needs richened up some as it has a very slight bog and some popping now. The additional air bleed screw works and you can for sure make it leaner at idle with this adjustor. We got it to run very good with several combinations of rod setting, air screw setting and idles settings. Seemed EZ to tune to me and several variables to play with. I really think it came setup almost perfect and we actually made it slightly worse although still quite acceptable and ridable. We probably should have left it as shipped and just leaned it out with the air screw but wanted to play with it some. I think we are at 3/4 leaner on the rod and i bet 1/4 - 1/2 turn is all it needed. The cool thing is you can manipulate it EZ with the air screw and idle adjustment.
So... I feel it is very good. Bike ran nice, no holes or flat spots. Steve is going to play with it some more but it is right there. His bike has a open muffler and was no issue. Will work up pricing on the final assembly and let people know whom are interested.
thanks
Very EZ to get to the air screw, idle and choke as configured even with the big IMS tank. The rod was EZ to as you can just rotate the carb and pull the slide out without removing the carb.
Simple single pull throttle...
