i have a 87 jawa 210 and don't have much problems other a small gas leak under the bowl (sometimes) and twice since driving it it has climbed past the usual 35km to 45km but i would have to stop or turn and never get it back up again? Anyways if you find an easy way to get parts other than the german site mz-b let me know i also wish i had a manual too-. ride free
