I dropped off my 1992 XR250L carb at my local Honda dealer and one of the techs said that for $10.00 he can modify the pump accelerator on my carb. He showed me the before and after results and normally the small L shape jet at the inlet of the carb will spit out a 4" fuel squirt. After the mod it now shoots out about 5 Ft of fuel almost in a straight line? I installed the carb and man! this thing really works, I no longer need to used the choke just jive some gas, the engine sound much better and the throttle respond is excellent. Very minimal power gain but the throttle twist is much crisper. He performed this mod in less the 10 min!
He did say that the return spring was cut almost in ½ and that the accelerator shaft stop was folded down to increase the travel.
My question is: who many of you know of this trick? And what exactly did he do to my carb? Is it just me?
