so im pretty well commited. have a 77 yz400 engine plus shipping quoted at $354.82 but i need some stuff to go with it.

Needed:
-A nice Pipe and silencer
-a set of vforce3 reeds
-a carb
-intake boot
-kick start arm
-shift lever
-CDI box (and any other electronics)
-new chain gaurd(the ones broken on the engine im buying)


I need to know what carb to get, what and where the hell to find a vintage performance pipe, vforce reeds might be hard and what electronics i need.

also, would my current clutch cable work? and im wondering about porting by flotek, how much and what to get done to make her rip.

any other tips to make this go smoother would be awsome.

thanks guys.
 
Ok well, pipes seem to be a kick in the nuts. found some stuff

DG pipe ($200 OUCH)

SILENCER(2 CHOICES need help)

choice 1 (100 dollar DG)
eBay Motors: DG 1977-1978 YAMAHA YZ400 TYPE II OVAL SILENCER 21-4414 (item 200234746882 end time Jul-26-08 14:42:41 PDT)
OR
choice 2 (40 dollar random)
eBay Motors: Yamaha YZ 125 YZ125 250 400 5NY Exhaust Pipe (item 190155057047 end time Aug-15-08 14:25:25 PDT)

now that random one, im not sure if its for the old yz 400 or the new one. doesnt say. looks like it would be for the old one, but im not sure. 300 bucks for exhaust is a kick in the nuts. o well.

so far up to around 700 bucks.
