Re: Loss of power, torque. Sputters at full throttle

It's not really a choke, rather an enrichment valve. The control is just inboard of the left grip. There's another thread by a guy with a broke choke, with pictures.

Yeah I have a choke, but the cable is broken. I pulled on it when it was running and it turns off. I checked the S hose and it was fine.

Did you remove the air filter and check the inside surface? The airflow is from the inside to the outside so the bugs and crap plug the inner surface first.

Re: Loss of power, torque. Sputters at full throttle

I imagine that he means the engine. Suddenly enriching a warm engine will shut it down. I learned this the hard way, one day, when I forgot to turn the choke off, and when the engine got warm, it spluttered. Turned off the choke, and back to normal.

He said "the cable is broken. I pulled on it" I reckon that means that he pulled the broken end, and operated the choke.

If he can do that then maybe he can pull it while the bike is sputtering to perform the test I suggested.

But, then, maybe we should stop speculating and let him speak for himself...

Re: Loss of power, torque. Sputters at full throttle

Either way, first things first, fix your choke. It's going to be hard to maintain a properly running bike when all of the things that are supposed to be working on it aren't working...even if it was running fine while it was broken before, this needs to be corrected.

Was it without choke when you bought it? How did the PO get it start without choke? I see you're in Florida, but all it takes is a slight chill and these things simply won't run without choke. Did he adjust some carb settings away from the factory default that could play a factor in the current issue?

Re: Loss of power, torque. Sputters at full throttle

I took out the carb and cleaned it, but that wasn't the problem. Come to find out my valves needed to be adjusted. Now it's running great. I still have to eventually change the springs on it. Does anyone happen to know how much those springs run for? BTW Thanks everyone for they're help.
