I was wondering if anyone out there has a problem with their Raptor coughing or stuttering from harsh landings or when blitzing whoop sections. I've had this problem alot and was told it's because the stock carbs work on a vacuum system and on hard landings the vacuum is simply not enough to hold up the slides. If there is anyone out there that can help, I would really appreciate it before I plop down cash for something else. I would much rather modify the stock ones because I like the light throttle spring and the quick throttle response but I can live with the bike length I give away each time it does this. The Nationals start in 2 months! Thanks for the advice
