darrensn Posted December 2, 2012 Report Share Posted December 2, 2012 Hi, just got a 2003 Beta Rev 50 (4 speed) for my son, The screw on top of the gearbox where you fill it with gear oil has a strange female socket type bore ? It looks like a standard hex bore but with the corner points removed ? So It looks like a splined bore Is there a special tool to remove this , as an allen key does not work. Not sure if its a original part, but its in really tight. Any help appreciated ? Also, whats the best sparkplug to use. I have BP5ES for my other sons Evo 80, are these OK ? Thanks ......
