Hey guys. I bought an 84 110 threewheeler a few months ago and got it running. After riding it around for long periods of time, it starts to bog out, especially if I give it full throttle. It gets so bad that the bike just shuts off and stops working for a few minutes, then you can start it again. I adjusted the clip on the top of the needle in the carb and it made it a lot better, but it only extends the time before my bike ***** the bed. Any tips? Maybe the oil is too thin and the bike overheats? I've been stumped.

 

I'm running 10-40w, just to save someone the question

 

adjust the valves might be too tight when its hot also check fuel tank petcock for full stream of fuel, clean carb out, fuel filter, also loosen gas cap to see if vent is clogged creating a vacuum not allowing fuel good luck and have a great day

 

I would say its probably not getting fuel when it gets warm or the coil is going out.
I have had machines that do the same exact thing, the coil was going out and when it got hot it would loose spark and not want to stay running and loose all power. Put a new coil on and it was a totally different machine. Just something to think about
