Hello Everyone,

I just noticed that my Raptor has a slight Hesitation while going forward and reverse. If you keep the throttle constant at very low speeds, the engine will hesitate. It seems fine throughout midrange and topend. Keep in mind, my machine is all stock!, no modifications have been done with the exception of the front countershaft sproket. I replaced it with a 12 tooth but thinking about putting the 13 tooth on as soon as I purchase an aftermarket exhaust system. I never even touched the carb settings. Any suggestions on how to correct this problem would be greatly appreciated!!

P.S. I'm thinking about purchasing either the Big Gun "Quiet Core" exhaust or the GYTR Carbon Fiber slip on exhaust. Again, any information would be greatly appreciated!!

Thank You,

Check and make sure that your choke is all the way off. Even if you don't use it check it. Hope this helps!

 

Usually a hesitation is caused by a lean condidtion.

Try this, run it at the rpm that creates the hesitation, then pull the choke on very slowly. If the hesitation clears up, you are lean, if it begins to get worst without getting better first you are to rich (unlikely). The way you described the problem it sounds as it will be in the mixture screws. If you are to lean turn the screws counterclockwise (while looking at them), and vice versa if you are to lean. Do both carbs 1/4 turn at a time.

JPB...

 

The lean condition can also be caused by the now notorious poorly made intake boots. I'm sure that every Raptor owner has heard of the carbs falling off. Obviously, yours have not fallen completely off but they may be comming loose. Check to make sure that the carburetors are fully seated into the intake boots and that the clamps are tight. If these connections aren't tight, air can leak past and cause a lean hesitation.

Guys,

Thank you for all your help. When I go over to my parents house this weekend, (That's where the machine resides) I will be sure to check the intake boots to make sure that the clamps are tight on the carbs and also try pulling the choke when I notice the hesitation. I appreciate all these responses.

When it comes time for me purchasing an exhaust. I will be sure to check with you guys.

Thanks Again!
