Thanks for the replys, I finally got ahold of Bid dog and they also said Andrews gear sets in aftermarket cases see below the mail I received from BD:
In the 2000 model Big Dog Motorcycles the transmission was assembled
in-house with ANDREWS gears and an aftermarket 5-speed case. Usually,
JIMS, Total Performance (TP), or DELKRON, depending on the model. The
serial number would indicate who's case it is.
Also this is the model clutch assy. that was installed by big dog on 1997-04 models:
PC-1200-C 1990-97 EVO BIG TWIN 1997-2004 BIG DOG MOTORCYCLES
CLUTCH PACK HEIGHT 1.345"APPROX.
9-PC-018-90 FIBER CLUTCH PLATE (.090")
8-PC-019-90-A STEEL CLUTCH PLATE .047"
2-PC-019-90 STEEL CLUTCH PLATE .080"
PC-4 REPLACEMENT CLUTCH PACK (ALL ABOVE INCLUDED)
Also Big Dog sent me instructions from Primo and it says in the instructions to add Dextron III ATF to the Primary? I have not heard this before and will have BD and if necessary Primo to confirm it?? I have been using regular HD primary fluid and have no clutch fuction problems and I know when I got the bike it did not have ATF fluid?
