Exclamation Help YZ80 1989 problems

my bike.. isn't hitting band.. when it is about to it jumps in and out of band... and the revs go low... i've tried a few things.. i cleaned out my carbi and my air filter.. n my spark plug.. but i still hae no idea wat could b wrong with it.. my exhust has a few small cracks in it.. could it be that...?

it was great when it running properly.. it could beat alot of newer models specialy in a straight out drag..
but now it jus goes in and out of pand.. and band doesn't feel as powerful...
any help would be great..... i'm lost...
