RE: WHAT ARE THE KNOWN PROBLEMS WITH MUGEN MBX5
Well I guess since this thread is active again I'll give a little update since I bought mine quite a while and raced it half a season, this thing is brilliant. Not a single problem with it, I built it with the aftermarket A Main diff seals and have had no issues. I never tried the factory ones so I can't speak for them. I've yet to rebuild my shocks they are amazing just replace the shock oil once in a while and it's always clean.
