I had my engine rebuilt and its running great. But the mechanic (not Yamaha aware it appears) did not have the plugs of the harness and carbs plugged in correctly. I got flashing error codes at idle.
I did some research and found some info. It appears the connectors are different and plug into certain carb locations only. But I could have made a mistake. One connector was left unplugged by the mechanic. It runs great when its cold. But once warmed or not very cold outside it bogs down. Leaving to cool down a while and starting again and its a different engine. Something is not right with the fuel mixture it seems.
Anyone with specifics on what goes into what plug so I can very it. Also is there any adjustment I can check which may be wrong with it doing this?
This machine had gotten too heavy for me and I cannot lift the back end when I get stuck (happens a lot with this oem track). I have to drive over 6 -8ft drifts riding the top for long distances. I either go off the side and stuck against brush or dig a hole 3-4ft deep and stand in a 5 ft hole and have to dig my way out. Knowhere to turn drive out only turn around. This is a 3-5hr job(each time) Its going to kill me.
I need a lighter sled and far more capable in deep snow. A lot more capable which will claw through anything. Maybe a 1.5" track in a single seat fan cooled chassis would shed 200lbs off the sled.
