need help. My 426 hick ups out of coners and on hard landings. Some people have told me to check the bowl for debris and to clean the air filter. I have done both. Also I was told to check the packing in the silencer. By the way I have a WB r4 with tapered head pipe. Could it be jetting? This set did not effect my 98 400. Also I heard that 2000-2001 426's are common to hick up problems. What are my cures....... Thanks

Hickups are not common on the '01 from what I can tell (my '01 has none at all). I would start by cleaning the carb out really good. Did it do this with the stock pipe? If it runs OK with the stock pipe (and stock jetting?) then I would think that the problem is jetting related since the problem appears if you change the pipe and/or jetting.
