HELLO THERE! I HAVE A JAWA TYPE 354, AND I FOUND AN ENGINE FROM A IZH PLANETA SPORT-ENDURO! I got the engine in a big box ... :-) and the crankcase had been cracked and welded! DO YOU HAVE A REPAIR MANUAL, OR AT LEAST SOME INDICATION ABOUT HOW COULD I PUT IT IN ONE PIECE AGAIN? :-) I MUST MENTION THAT I HAD AND A DNEPR MT-11 FROM 1992 , BUT I SOLD THAT ONE AWAY , BECAUSE IT WAS HEAVY , THE SPARE PARTS WERE CRAP...AND SO ON... THANK YOU KINDLY!( GABRIEL)
