Question about stalling when down shifting ?
This only has happened twice since I bought my 01 Low Rider. It idles fine runs great and and seems to be tuned up. Every once in a while when rolling up to a stop while down shifting my bike sometimes will sputter when holding the clutch in during a slow roll. It seems like it will happen more around 3rd down to 2nd and if i hold the clutch to long it will go as low to gasp before i roll the throttle. Yesterday when this happened it did stall for the first time. after that i just started again and all was fine the rest of the way. Now this don't happen much at all so that's what gets me ? If was frequent i would lean towards dirty plugs or something ? Any ideas ?

Bike Stalls
I'm guessing since it is an '01 you have a carb fart going on? A phenomeon no one can figure out, had one with my '02 also. Next question; wll it sit and idle without massaging the throttle? You stated you are rolling with clutch pulled in so not sure what's gong on but I will advise you not to you use downshifting exclusivley to slow your bike down, VERY hard on the clutch. I would set your idle higher (assuming it is carb'd), check air filter first,.. then have someone check your idle/throttle cable adjustment since it seems to be while you are rolling. I have often heard people call the Hypercharger a "horsepower reduction device" so it may be starving it of air.

Carb farts can be "cured" with proper tuning of the CV carb; if you run out and buy a new carb, THAT one will need jetted also. The stock CV carb is perfectly fine until you get into high-zoot performance where you need mixture beyond it's capability. If you threw on the HyperC without a re-jet (or an insufficient one), that is probably the problem (along with too low idle speed). I recommend a dyno run to check and a book called "How to Build A HD Torque Monster" by Bill Rook for carb tuning you can do to improve CV carb performance/driveability issues (and at low-no cost to you exc. the book!).
