The Yamaha dealer is offering this "Speed Kit" as a $150 option to increase top speed. I am guessing that it involves a remapping of something - but what? And how? And will it be detrimental in any way Thanks, this is my first post.
If it is a A/C motor drive you just reprogram for 20 mph and put on 205X65X10 tires . This will give you about 22 - 23 mph. You will still have torque and smooth acceleration.
Ask him if the speed kit comes with bigger tires? If you have a PTV model you already have them, if you have the 8 inch wheels you are programmed for around 12 mph. I do not charge the customer to increase the speed if cart was purchased from me,
