Sputtering at high temp
I've had this 95' vn750 for a few weeks now. It's got 54k miles on it so I assume it's been through some stuff.
The problem I've been having recently is once the bike gets hot it starts sputtering at higher RPMs and will stall out.
I want to start out by saying I definitely feel like it's running rich. I can smell it. Also in the past few weeks I've had issues going places and having a hard time starting it back up. I have to use full choke to get it started back up. The bike has custom ear shaved exhaust and I'm not sure if the previous owner re-jetted for this but I want to assume they have since it has so many miles on it.
I don't know much about the coaster thing I'm reading about in these forums. I did do the pick up coil mod the other day to help with hot starts.
I have a manometer and plan on attempting to sync the carbs too. I believe the front cylinder is running really rich and the rear cylinder is running really lean. I feel like this could be the source of my problem.
Again the problem is when the bike gets hot it will begin to idle erratically (jump up in rpms) and then when I hit higher rpms in gear it starts to sputter, slip, and stall out. It has no problems idling when starting it up cool. The problem only arises after riding for 20-30 minutes.
I'll take any advice I can get! If anybody has any ideas to what could be the cause of this issue.
