Is there a specifec difference is jet sizes between the two carbs. I see a lot of jet setting with 5 in between the sizes. I will try the 160 and 162, I really appreciate your reply and input Thank you
I need help, I have a 2005 Raptor 660r with a Yoshimura TRC Full exhaust System. I also have a UM Aluminum airbox with no lid,K&N air filter, and aftermarket intake boots. I have been trying to find the perfect jets for my carbs. I have tried a 157.5 and 152.5 but had no top end. I then put in a 175 and 170 but now it sputters in the low end but has top end all day long. Any suggestion? Also my elevation is 500 feet above sea level.
