This pink wire will not have anything to do with power in the mud. It only stops the quad from making more power when in 4th gear. If he needs more power in the mud down shift.
To find the pink wire to see if it is still connected. Look on the left side on the frame under the tank. There you will see all the electrical wires going into 1 round system. Pull the wire boot cover back. There you will see the pink wire,ours on the 06 Honda wasn't exactly pink it was an off red color. If it is connected,then the limiter in in place and it won't produce the most power the machine can make. If you cut it and then tape the ends it will run about 46 with a 80 lb kid on it. That's what our's will run. The wire doesn't keep it from going into 4th gear,you put it into 4th gear. The wire just keeps it from producing the most power when in 4th gear.
Another thing you may want to do is change the rear wheels . The tires roll alot of the Honda. Because they are so tall and have a high profile. Look at the rear tires on Codys quad. The turff Tamers are good or any set of wider width and a lower profile works great. We run Kenda Claw MXR's on the rear.
You can change some sprockets and help slow it down. I know where your coming from. Because Michael has been racing for 4 years and STILL when he starts flying around his track here at the house his mom goes crazy and runs in the house and won't come out.
If you need any other help just feel free to ask away. Pappy and I will help ya.
