Lots of tuning today, about half of which was a waste of time because I was having other fuel issues. I put a filter in the line and I think that is messing with the flow into the carb. With my mlm intake the carb sits almost at the same height as the petcock and I think it is causing issues. I took out the filter and shortened the fuel line.

Given the above, I don't think I got much "good data" during testing today. I ended up back on the 120 main and middle needle setting. I think that it is about right. 125 is real happy in the mod range, but bogs out at WOT. 120 feels great, but may be hot.

NAME THIS SYMPTOM

The bike will be running well until I take it up to 6-7k rpm for most of a block (well below 300F, but warmed up now) and on the deccel it seems to lose power or cut out until I pull the choke. It will then return to idle and sound happy for a moment, pull with throttle for 30 seconds, then you got to the the choke off. Back and forth like this.

I'm hoping it was a bad seal on the fuel filter/lack of drop into the float bowl.

I think the tuning may be almost right, but I just need to gear it up so I top out at 7K and then look into clutch tuning.
