Yamaha Wolverine 4

i bought a 1995 wolverine in febuary that was n bad shape, i gave $3500 for it, it was honestly held together with duct tape!.....its motor was blew up and the front fenders were cracked to pieces because the guys wife got mad and took a baseball bat to it, it didnt have back fenders, it had no brakes, the bars were bent, and the left rear tire was bald to the extreme!!!....it was missing the carb and muffler along with the left headlight and the front driveshaft was bent preventing the michine from moving...well i bought the quad and took it to my bilding and called dennis kirk[atv mag] and ordered a complete set of black plastic and some ITP wheels and a big set of mudlites, i also orders a liftkit that added 1' of lift, insted of buying a driveshaft i got a WARN 424 select[which is awsome for wheelies] [now the atv rolled]. i also added a pro circuit pipe along with powermadd handguards, and racks, tag handgrips, handelbars and some  knockout stickers, i put on new brakes and a manual clutch[on the bars], next i added a battery and a cheap carb then i added gas and started it up[it smoked like fire due to there being a awful oil leak draining the oil]it made a clicking noise and i turned it off, i ripped the motor out and sent it to my neighbor "big D" and he took it apart and added new pistons and rings along with a hotcam camshaft and a edelbrock carb with a moose jet kit, he added an EPI clutch kit send it home!...i was now ready to re-install the motor and i noticed i lost the bolts so i welded it in...i now wanted 2 test it out so i started it up and rode it to the local gas station and on my way back it stopped moving!!, the rear differential locked up, now when i buy a new diff.i should be ready to ride it again.
