About two months ago I tried to attempt to help pull a guys quad out of the mud with my 3 wheeler (against my better judjment). I tied a rope from his quad to my 3 wheeler and let it rip. Well after a minute or more there was this load poping noise, and felt almost like a gear sliped. Latter I tore the side of the motor apart and took the cluthch basket off and inspected everything and all looked okay fromwhat I could see. Went for a ride the other day and noticedthat in second gear when the motor is under load it makes this clicking noise ( made the noise twice) and feels like transmission ismissing a gear then its grabing the gear. It then grabs and dosent make the noise again. It is especcially noticable if you are climing a hill. Any thoughts on this problem or what might be the cause would be appriciated thanks Glenn Oister
