I have an 02 road king, rinehart true duals and a thundermax tuner. While riding down the road with a steady throttle my bike will just jerk like it's going to quit then it runs like nothing happened. Sometimes it will run without doing it sometimes it's more often. No fault codes come up and TPS has been replaced. Any ideas?

 

i have the same crap going on with my 2005 ultra clasic,i have replaced the map,iat,ets,intake gaskets,cps,injectors,next step coil and wires,

 

Check your crank position sensor located up by the oil filter. These are known to go bad and bike will run erratically.

 

Change plugs and wires

 

I have replaced it and it did not help but thanks 95custmz.

 

That is my next step plugs and wires, Thanks.

 

Intermittent jerking and misfire

Title made me laugh. I was thinking of some sort of premature (sexual) dysfunction.


On the serious side if it's carb-ed it could be a re-jetting issue. After adding upgrades, racing components, you would have needed to rejet the carb.

If EFI you may need to try a new map.

 

No it's fuel injected

 

Also tried a remap!?
