chappynam

hi guys. I found the old chappy in my granny in laws garage. I managed to get it running and it runs really well. I don't know anything about bikes but it runs. there are 2 problems with it though. the first being that after running for a while it looses oompf and won't go anymore then it has to sit for a day or 2 before it will start again. is it a heating problem? the 2nd problem I have is that my kickstarter is super dodgy. I think it was broken and then welded back on. now the weld is starting to break and the kickstarter is rubbing against the exhaust. any ideas on how to fix it? I spoke to a friend and he said you can't just weld on a new piece I would have to strip the engine and work on only the kickstart. any help would be greatly appreciated guys. thanks in advance

thanks Tommy. I do have a question for you guys out there. I found a chappy in my granny in laws garage. I managed to get it running after cleaning everything!. but I still have 2 problems. the first is the bike stops running after a while is it overheating? also the kickstarter has been welded on and is bent so its now rubbing against the exhaust. the Yamaha shop in town can't help me with a new one so can I just cut it off and re weld it? or is my bike gonna explode?
