Enough of the butt kissing. Here is my problem...
I bought an 04 YFZ 450. It has a YZ426 swap on it. The bike runs great everywhere in the rev range. That is until I let completely off the throttle. Then it dies. There are no wires going to the throttle. The only wires going to the carb are for the TPS and it is a 3 wire plug. There is a red anodized plate on the bottom of the carb. Im not sure what that replaced.
Where would the TORS go on the carb? Any suggestions as to what I need to do? It is time to go ride and this is FRUSTRATING ME!!

My bike came with one that the previous owner put on it. There should be some markings on it to identify it.

I took a crash course today in carb rebuilding. I cleaned all the jets and passages and made sure there was no clogs or dirt ANYWHERE. I dont remember off the top of my head what all the jet sizes were. I wrote them down, but they are in the truck. Ill get them in the morning. I know the pilot jet was 45 and I "think" the main was 72. The other fuel jet was i "think" 64. Again Ill double check in the morning.The air jets were 100 and 200.
So I put it all back together and it didnt fix anything. Still runs great everywhere but Idle. No dead spots or hesitation anywhere in the rev range. Throttle response is quick and not a hint of stumble. Only Idle...
The only thing electrical coming off the carb is the TPS. Nothing on the throttle.

The TORS goes from the throttle and the carb to where?? What actually controls it? Does it go to the rev box? I am trrying to find out how this works. I dont know if the guy used the rev box frrom the 426 or the stock 450. Is there a way to identify it?
AAAAHHHHH!!!! It is driving me nuts!
