ok so i have a 2001 f4i, just finished ripping the bike completly apart to replace the speedsensor which by the way is a pain in the *** since its located ontop of the crank case, replace plugs, coolant, oil and all that good stuff, the problem is that when im in 1st n 2nd im getting alot of hesitation in the lower rpm, almost like the bike isnt getting enough fuel, i thought it might have been a spark problem but obviously not, so i was wondering if anyone had any input, my conclusion is that its either a clogs or faulty injector( anyone know what kind of injector cleaner works the best in these bikes) or when i dropped in 2 months ago i broke off the fork bar that holds the throatle on and am thinking that maybe the throatle is sticking. dont really want to replace both the throatle assembly n injectors right now dont really have the money to blow, so if anyone has any input to what they think the problem might be i would appriciate it. thanks in advance

 

you need to do a bunch of testing before you just go replace parts. i have no idea of your mechanical ablilties & dont feel like typing a book in response to your post. so feel free to hit me on a chat client if you feel inclined as you didn't put any information needed to diagnose the problem. good luck
