Anyone ever experienced that after 10 min ride the Speedo goes to "0", the engine hesitates and bogs for 2-3 sec and you can continue riding but the engine warning light comes on after 1min - checked then after stopping the rised DTC ( showing P0501 - VSS low EFI ). Cleared the DTC, started the engine after 1 min, went riding, and after 10 - 15 min the same story starts again ! Anyone knows how to fix this ?
should do - and i think i gonna pull out the VSS-sensor from the tranny to see if itīs damaged or maybe full of metal chips...
just iīm not sure if this "special" behaviour is maybe caused by another things as well ..
changed the VSS and the CKP for new ones - no change..
it seems to have something to to with the Vance & Hines THROTTLEPAK..
gotta get this thing removed and try again..........
WTH ! I disconnected the PC5 and Autotune and the Throttlepak - no changes !
I found out that these symptoms happen each time you accelerate / deaccelerate or lean the bike in in thight turns - i will take it to the dealer today to see whats the problem at last.....
keep you posted
If VSS was changed and aftermarket items removed, it's in your wiring. You have a short to ground. Trace wiring and verify nothing is amiss or chaffed. I would also check the ECM connector under the seat as often the connection can be compromised when not being properly seated.
