basically ive piked up a cheap runner sp50 2004 and was wondering how easy isit to fit he 125 or even a 180 lump and what will i have to upgrade? cheerss..
will need to cut the mount, New wiring loom, cdi,coil bassicly everything. It'll be easier to just buy a 125. Or are you one of these "tits" Who can't wait a year for a 125.
The mount you refer to (silent block) is part of the frame that need's cutting off a 125 frame and welding in place. Or just bodge it in like most people do and make a crap vibrating ilegal piece of crap. Or as already said, wait until your old enough.
