bought a new 2010 diamo / tuscany 50 . have had it running but is very hard starting. i´ve run nearly a full tank of gas through it. next time i go to start it it starts really hard and after a lot of cranking. any ideas ? also looking at making it go faster , where to disconect the pink wire and change the limit restricter. need help! can ride my goldwing but like my tuscany if it would only work for me better....
