  • 1997 ts 770 problems!

    i have a 97 ts 770 . apx a 18 months ago i was riding and the motor just came apart . so rather than mess around i got a short block from sbt . installed and rode for apx 6 hours on 2 seperate occasions . heard bad sounds again and checked plugs . they looked good so checked compression manually on water and found none in back cylinder. broken crank shaft . so they warrantied the motor which was great . put motor in and this time rode for apx 3 hours and at apx 50% throttle it just started to bog . checked plugs and rear appeared to be sand blasted . big hole in rear piston !!!!!!!!! . apparently extremely lean . but looking for some help . thanx [img]/graemlins/angryfire.gif[/img]

    I can not belive you burned up 3 motors and haven't rebuilt the carbs or checked oil pump/lines. Sounds like you have a real bad air leak or realy bad carbs. Take them off ond find out what the problem is. you will probably find filter cloged.
