Hey guys Im new to this site. Well i ride a KFX 400 2006.
When i shift to fourth gear it seems as it doesn't gain anymore speed then it does in 3rd gear. When I shift to 5th gear it seems to slow down. 45 mph is the top speed i have hit with it. I'm pretty sure it has to go way faster than this. I heard they could go up to 75mph in stock. What could be the problem here ? Will I be able to fix it myself ? Also I dont have the hose that goes on top of the gas cap. Is it necessary? Thank You for any help given !
