My first bike was a Yamaha JT60 when I was 6 and sometime after my Dad brought home an RV90. I was so short he took the seat off so I could ride it but that bit my ass hard so I asked him to put the seat back on it and learned at first to do the midget dismount and later to tripod.
Glad you had fun on it - but those old rotary valve suzuki's wouldn't pull a greasy string out of a cats pissy . LAME in the HP dept. . Had a suzuki TM 75 - what a POS I could outrun that turd on a bicycle .
Did scar my left calf for life with it though , clutch ball broke off the end of the lever - put it completely through my left calf and barely out the other side . Just noticed it this morning while drinking coffee and remembered that.
If it doesn't have Reed Valve - steer clear and the rotary valve doesn't help fuel economy at all = lame - yeah .
