St0fxxx Posted October 10, 2012 Share Posted October 10, 2012 Hi guys, Anyone out there with an 89 DT125R which they know still has the original block in it. I've just checked mine and it has 3MB00 on it. I cant find anything on tinterwebz that says this is right (in fact things that say its wrong). I need to do the top end and know that the piston sizes differ 88-89 (56.40mm) and 90 onwards (56.00mm). Then i guess then ive gotta see if its already been bored total PITA getting a 2nd hand bike, i wanna know everything Thanks in advance guys $t0F Link to comment Share on other sites More sharing options...
