    sho hesitation

    May be an odd question but when I punch my ski it hesitates before it kicks in. I can be doing 60 and hit it and the hesitation is almost feels like the engine will quit. Anybody ever had this?

    GPRSHO R3 flash ET high boost wheel. Happens at any and all rpm. Afr's are perfect low, mids and top.

    My buddy I ride with and I were having the same issue with the R3 tune doing this when it is really hot. I have et 15.5 with r3 and he has b1 with r3. Hesitates somewhere around 7500 rpm I think. It only does it when it's high humidity and very hot.

    I never really felt that until it got hot. Did you start feeling this right after you installed the r3 or have you had the r3 installed for a while and now it just started happening?

    Hey jim, last time I was out, I had a very similar issue. I slight bog when hammering on it . seemed to go away after 20 mins of riding. but I think I may have found my issue. my fuel tank breather line check valve got plugged and my fuel tank was getting sucked in big time.

    It's been like this since day 1. Over a year.
