  1. I have a 2018 Mossimo ALLI 700. Basically replaced everything. Worked directly with the great team at Motorcycle Doctor and SCAUTO. Replaced everything and for whatever reason the owner got into the UTV and drove it like he stole for 40 miles. Cannot stress enough if a buyer purchases a HISUN, BENNCHE or MOSSIMO off Walmart or Amazon they need strict break in instructions. Mossimo 700 would start with gas similar to a carburetor style setup. Please follow these steps if this is happening. 1. Do a compression check...If you are under 100psi you have something blown or broke on the main head 2. We had 90 PSI so we started with the valves to see if they are staying open by adjusting them. They were in spec and timing was on mark 3. Head was removed to inspect valve springs. All were tight but one was loose. On the 700 the springs are single stage so it's tricky if you have an older one with dual stage springs because one can be snapped. 4. In our case one of the single stage springs snapped and thank goodness nothing other than a broken spring created the lower compression. Spring replaced and valves readjusted running like a champ. You can feel a broken spring it will spin of feel loose versus all the good springs will be tight and not able to spin.

  2. 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
