Your Royal Sudbury is Urichi Black and Marshall Gold.

Thanks for the additional information. Yamaha calls your "grey" Standards "Midnight Silver". Which of the VINs belongs to "Paris"? As for "Royal Sudbury" is it the same color brown as the US Royale (Birch Brown/Copper Brown)? Like this?: Or is it more like this (Royal Maroon)?:

Thank you, @sailur Your two Standards nearly doubled the number of 1986 Standards in my database. (Very rare) Did you know that there was no 1986 Venture Standard imported to the US? What color and mileage is each of your Canadian Ventures?

31 mpg (US). Only fair/middling mileage. Perhaps you were doing a lot of high speed "testing"?

1983 had no reserve and a tool (screwdriver or wrench) was required to turn the petcock on or off. Starting with the 1984, a reserve and a hand turnable knob was incorporated. The 1990 and newer petcock was changed to have the fuel outlet on the left side of the valve. (I have no idea why the change). All three petcocks will bolt onto any year fuel tank, though fuel hose and routing may need to be changed. Also, if a 1984 or later petcock is used on a 1983, the right side cover will require a notch to clear the knob.

Yes, the vacuum port should be at the six o'clock position when slide is in its bore.

That bushing (90381-18049-00, "Bush, solid") is no longer available from Yamaha. There IS at least two available on eBay, but... https://www.ebay.com/itm/YAMAHA-83-87-XVZ1200-XVZ-1200-VENTURE-ROYAL-REAR-UPPER-SUSPENSION-ARM-BUSHING/112864209229?epid=19016431588&hash=item1a473b294d:g:fBEAAOSwC6haposJ

The gear indicator switch uses a brass pin as the sliding contact. This pin becomes worn and the tip flattened from wear. This reduces the effective length of the pin and enlarges the contact area with resultant poor contact. Remove the Phillips screw and pull the pin out and the spring behind it. Either replace the pin and spring or stretch the spring a bit or place an appropriate shim between the spring and pin. File the end of the pin to more a point to help with good contact.

RUSTY! Usually the dirt inside is carbon from the brushes. The amount of rust showing would make me nervous about reusing it. The field magnets have been exposed to a lot of high moisture conditions. When the magnets begin to rust, they often start to spall. The consequence is either shorted armature or a severely dragging starter due to the rust and fragments wedged between the field magnets and the armature.

Seeing your engine sitting there on the lift/bench, with the starter motor out there in the open, reminded me to mention swapping out the original two brush motor for a four brush starting motor. Easy peasey at this point in your project. BTW, I have a Yamaha four brush motor for sale. (hint)

There is no need to lubricate the outer race of the bearings. The outer races are not supposed to move. Oil the inner races and balls with motor oil; that's what will be lubing them later.

Actually, the newer style shift cam segment appeared for the first time on the 1998 XVZ13 and the 1999 VMX. While your shift cam from Randy may indeed have come from a 1993 XVZ, it had been upgraded after the 1993 Venture was manufactured. The newer style shift cam segment DOES have pins. The pins are captured by the one piece segment versus the sheet metal side plate on the old version. Sometimes the ears on the old side plate became bent outward, allowing the pin to fall out.

The pictures are from a collection of hitch mounting pictures I have. There are at least two different bikes shown. But on both of the bikes I've had a Markland hitch on (1990 and 1991), the vertical bar running from the ear on the ball hitch plate to the U-strap mounted on the saddle bag/crash bar frame has been angled. Maybe just manufacturing tolerance or minor changes Markland made over the years? I don't think it will matter.

Yes. The clutch assembly is bolted to the main transmission axle. You will have to remove the clutch assembly from the main axle in order to transfer it to the new main axle. Since the clutch basket is secured to the main axle with a big nut, requiring substantial torque to loosen, it is best done prior to splitting the cases.

Do these pics help describe the problem, @cowpuc ?

I have a complete gear set from a 1986 1300. Will drop right into your 1983. Yours if you want for $30 plus shipping.

Will, you mention the "plate, seat", but it is not pictured. The "plate, seat" is used on 1988-1993 Ventures. You are working on your 1989, right? The "plate, seat" often remains at the bottom of the lower leg interior upon fork disassembly because of the rubber seal/lip on the "plate, seat" creating a seal. If you don't have it out of the lower leg yet, fish it out and examine it. The rubber lip is sometimes damaged. If the seat plate is good, then lightly grease all those loose components to stick them together and on to the "spindle, taper" and slide the whole assembly down into the lower leg in one smooth motion until the assembly bottoms out in the lower leg. Attached is a diagram I made, showing how the 1988-1989 assembly should be. Also attached is Bob K's photo of the damping rod assembly, but with out the "plate, seat".

How, from the original owner?

Actually, it appears your final drive is from a Second Generation Venture, not from a First Generation MKII. The final drive can be replaced without modifying or removing the engine, so I doubt, just because the final drive has been swapped, that the second gear has been fixed.
