hi I,ve had some problems with the tt ,looking for some advice.The 2 headlight bulbs blew one by one and then the main fuse went leaving me stranded.I replaced all and it worked but now the bulb has blown again.I think it could be a faulty voltage regulator. Cant find any damaged wire. Also the splines at the front wheel hub that drive the speedo are plastic and wear out after 10,000km. Is there a better replacement part than the origanal part. I like the bike but would like it to be reliable.
