I'm second owner of a 2001 Bayou 220 that was an adult ridden ranch utitlty vehicle. Bayou ran fine last summer than started leaking fuel from carb overflow and finally the throttle response dimished to where I decided to clean carb and install a Shindy carb kit.
Got all the new jets etc. installed (but kept the old jet needle as I didn't want to alter the setting and reinstalled carb on bike with the Idle Adj. screw and Pilot Air screw @ 1.5 turns open; cleaned air filter and connected carb to airbox. Bike starts quickly and over revs to 2000 plus rpms.
I checked the throttle cable and it is loose allowing slide to close - I thought it might be holding slide open on a high speed circuit, but it isn't.
Also pulled carb back out and changed the jet needle to the Shindy needle set to the 1st clip position - didn't change the rpms - still over reving.
Next I adjusting the Idle and Pilot Air screws out with no change and finally screwed them both in till seated - no change, bike stills starts quick and runs at fast rpms.
Bike starts quick has good throttle response when the throttle is wacked, it is just idleing too fast. What can I do to get the idle normal before I give up and take it to the shop? All comments are welcome.
