I just bought my first buggy, a 2007 Joyner 4 speed 3 cylinder. I'm not even sure which model it is, I think it's the sand viper. It runs great but 1st gear just started making noise. In neutral it revs with no clicking, in 1st there is a clicking noise like a stick stuck in a fan which increases speed with rpms. 2nd-4th and reverse does not make this sound. Any ideas of what this could be? Thanks
