Out of ideas.. Here's the run down.
Ran both of my 24DMs at Sand Wars. Both would bog at the launch. Swapped CDI and coil. No difference.
Fast forward to Amarillo Sand Drags.. Same issue, both motors. Swapped pipes, carbs and motors. Same issue.
In both cases, bike runs great up top. Just won't get off the line. Never used to do this.
Motor builder wants me to pull a clutch spring or two to see if it will go, but this doesn't make sense to me. How would the springs get stronger over the course of 4-5 years?
I just ordered new stator, CDI and coil as a last ditch effort to figure this thing out.
