i have a 2001 suzuki lt250 4x4. this four wheeler had been sitting up for some time and the people that had it before me werent all there. im haveing a couple of different problems with it. FIRST is bike will start right up and will fun as long as you want, it want ever cut itself off but if i cut it off it is very hard to get back started unless i wait long enough for it to cool down. then it will fire right back up and run good. SECOND is gas is getting into the oil however i have noticed that it doesnt have a fuel shut off. wondering if the fuel pump could be weak and its running through or if it is something alittle more in debt. and last the clutch is slipping i havent had any luck trying to find any sort of adjustment, i used to have a honda and it had and a bolt on the side to tighten or loosten the friction. im wondering if there is anything like that, that im missing. im asking all these questions because im haveing a hard time finding a repair manual for it. i would appreciate any kind of help
