Hi, im not that clued up on mods, could someone clear this up for me.
At the moment my raptor 660 03 model is totally stock besides the k&n air filter, i have the lid off.
Im about to buy a trinity VI full exhaust system, just wondering do i need to re jett my carbs.
Im not too bothered about any extra power gains just dont want to be running my 660 to hard incase the stock jets cant handle the new exhaust.
If i do need to rejett, what sizes would i need, 100% of my riding is off road if that matters, thanks for any help in advance
