FCR Jetting Question - XR600
(Click here to view the original thread with full colors/images)

Picked up a used 41mm FCR for my xr6 and need to know how it should be set up for 7K feet. Engine is stock, no snorkel, aftermarket header and spark arrestor. Thanks!

What was the carb set up for initially?
That'll be the million-dollar question!

If you are running stock header pipes, and a medium flow muffler, you may be shocked to find that your main jet size should be 142-145. This carb comes set up with a 170 main. I just dyno'd mine with EG analysis and anything above a 145 was way too rich.
