I just installed a FCR 39mm from sparks on my 426. Ive never ridden a bike with one it doesnt seem to have as long of throttle throw as a stock 400 carb it only moves like an inch and it wide open is this normal.What all adjustment should I have to make or will it be close from sparks the main jet in it seems small especially with that big of carb what are some of you fcr owners running and what all did you have to due to get it dialed in doesnt seem like it is running right at this moment but Im sure it will need some tuning.Help

yes the throttle is normal, we run a twist throttle on our 440 1/4 turn and it's wide open, we have had our fcr-39mm 2 years no problems,
