ok 4th installment of the no go massimo. so it took so long, been working my tale off. then went to maine and ate 12 lobsters. the stuff craig sent me from motorcycle docter was most helpfull, gonna try to attach the service flash. well i got the ecu controller in couple days, that fixed that problem, but still wont start or idle unless you hold gas peddle , then it takes off, yes mine will start in any gear. well i had the intake tube off, were throtle cable attaches it has a cover, i removed to find linkage to the throttle position censor , there was a adjustment screw with a red cap over it, plus the houseing had a black rubber plug in it. my little voice told me to didtch the red cap over the screw head. when i put it back together. so now outta options, i pulled the black plug, stuck a straight slotted scewdriver in and turned clockwise, took almost a half turn, but problem solved. starts right up and idles perfectly. by the way the t.p.s is a cts brand, thats a high end american made company, all the high end guitar makers use them , tone and volume pots. craig told me that the engine came out of a yamaha grizzly. but most important was my dipstick was marked wrong, not enough oil, clutch damage will happen. so i hopes this helps some other massimo owner. ps i just ordered a massimo mini bike
