u/Every_Rhubarb_Counts

Hey I’m having some issues with low rpm throttle hesitation on my DR. It has the TM40 pumper carb and runs well when I roll on throttle smooth. However, in the low rpm range there is this hesitation when coming onto the gas or blipping the throttle. It’s like a stuttering nephew until he finally spits out what hes trying to say. I’m new to carburetors so I wanted to see if yall had any tips on where to start.

I backed out the mixture screw (assuming it’s running lean) and it seemed like maybe it helped slightly but I ran out of adjustment room. That’s making me think I might need a different size jet? Or to adjust the clip position on the needle? It has no issues idling and starts right up.

She pulls hard once the engine catches up with my throttle input. I do get some pretty intense deceleration popping especially when she’s fully warmed up or it’s hot out

Hey there I’m having an issue with my new to me DR. I lost power after a full day of riding and the battery was completely dead. I couldn’t bump start it and had to get a tow to a friends. The starter button was a little loose all day and at one point fell out. Once I got home I connected a charged battery and the bike immediately started trying to start without pushing any starter button or having the key in the on position. Once in the on position the bike would start right up but it sounds like the starter motor is still running. I have confirmed the starter button is not making connection.

My thought is that something has occurred with the starter relay? Potentially that I was riding with the starter motor running to the point that it killed the battery and fucked something up. Haven’t had a ton of time to research due to trying to figure out how to get the bike back to my house

Any tips would help. The spring on the starter button is gone …

Pumper carb, full cogent suspension. Assorted farkles. Happy day. Now for a wind screen, luggage, and a safe season of riding 🤞
