I have a 1996 suzuki ltf250 quadrunner, I bought it used recently and I got it running. However, when I finally drove it, it runs fine at first, but later it started make a click noise when I throttle it and made a drag resistance like the gear didn’t shift fully. It has low, high, and reverse switch, but I don’t know if it’s a automatic transmission. Also it has a clutch pedal for me to shift the switches. What do I do to fix it?
