my friend found a '79 mx 100 the other day and a complete blaster frame good fenders carb tires and beadlocks, both for 100 dol. hes guna bring the mx to me today so i can check it out, does anybody know wnything about these bikes? are they good? can parts still be found easily? he said it still has good compression and the only thing missing is the silencer. any info would help out, ive never messed with anything that old, but cant wait to get my hands on it.
