I recently purchased 110 Yamoto ATV w/3 speedfor my son. Problem is it starts to whine horribly in third gear and moderate in second gear.( can be heard 1/4 mile away) Was told that this occasionally happens. Anybody else have this problem? Will it get better or worse, and if so, what is the fix? And has anybody tore a Yamoto 110 transmission apart, because I want to know if the fourth gear is in there, but minus the shifter fork like on the Suzuki DRZ110. Any Comments or help are appreciated. Thank You
