By Working hard to hardly work
Hey guys im in the process of rebuilding my massimo 500, and like a dummy I did not mark the cam. Im having a harder time finding timing info than i thought. Can anyone give me a no bs way to where and how i need to align the crank and cams to time this thing? Im still trying to learn how to properly time motors so any dumming down would be appreciated.

You will quickly see that I am new to this and don't quite know how to pose this question. I gave myself a Coleman 400 UTV for my 65th birthday a month ago."To Yaya: From Yaya" I've noticed a couple issues. First, as I drive around our acreage, sometimes it just putters, almost sounds like it's going to turn off. The other issue is the lights on the dashboard that correspond with forward, neutral and reverse don't match up to the actual gear. Sometimes it does but most of the time it doesn't. What I mean is that when I put it in forward to drive, the reverse light will be on the dashboard light. Sometimes it will be the forward light. When I put it in Neutral, sometimes the light on the dashboard /N lights up and sometimes it doesn't. Lastly the gas gauge does not register. Although the tank is almost full, it shows E / Empty.

Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

leaking from the output shaft from engine. Parts diagram shows the nut, metal washer, then the flange coupler. However when I took it apart, there was what was left of a plastic bushing. Assuming it seals between the washer and splines shaft. But the parts diagram doesn’t show this plastic part. What gives? Thanks in advance.
Hopefully someone out there is a T-Boss 410 electrics expert or a Massimo mechanic is viewing this. I parked my 410 and it was working great. I came back a week later and attempted to crank it and nothing. Turned the key and no power. Figured it was a bad/low battery so I charged it. Still nothing. Attempted to jump start it and still nothing. Usually when I put the key in and turn it to the first position, the display comes on and I hear the ECU and other items boot. Now it is doing nothing.
I slowly went through the electrical system and found the main fuse attached to the starter relay, part 71602 (pic 1) blown. I figured replacing this fuse would fix my problem. It didn't. I then ordered a new starter relay thinking maybe that part had gone bad and caused the fuse to blow, but a new relay did not fix the problem.
I have found a work around for starting the machine. If I take one of the purple/black leads (pic 2) and insert one of them in the bottom right of the starter relay (pic 1 and 3) then the machine will get power even with the key in the off position. I'm bypassing something but don't know what. I can use my right hand to hold the wire against the lower right of the starter relay, reach over and hold the brake with my foot, then take my left hand and turn the key and it will crank. As soon as I remove the wire from the relay the machine shuts down. I have even removed the power distributor box and it will still get power when I touch the wire to the relay. Of course this is not the way it should work but if I can't solve this problem somehow I may just have to rig a connector to the relay and bypass whatever is causing the electrical issue. Massimo has told me the purple/black wires on my model are not used.
Any help in figuring what my problem may be or other items I can try?
