The screws are 4mm diameter, 12mm long. Yes, there is a gasket for the choke assembly. Part number 3JB-14536-00-00 https://www.partzilla.com/product/yamaha/3JB-14536-00-00?ref=0b935775ba783008fc3eb8976f85607427091d8a

Throttle shaft seals seem not to need be ever replaced on the Mikuni BDS34/35. At least, I have never seen them replaced, although some have cautioned about too long carb cleaner soak possibly degrading throttle shaft seals. Carb parts to replace.xlsx Throttle Shaft Seals and Cleaning.docx

Thanks

Don, the pics USED to be in this thread, but not now. Can you fix it?

Yeah, Yamaha nomenclature sometimes seems irrational. Yamaha calls the oil pan on the First Generation XVZ "COVER, strainer". Go figure.

Thanks, Jeff. Your thoughts match mine. The reason I inquired about the battery cables, etal; was that I see RSV (and RSTD) battery cables from various eBay sellers for $4- $6 dollars SHIPPED! I figured that for that kind of money one could upgrade the First Generation cables real cheaply, IF the RSV cables were in fact larger. The lengths of the cables are different from the First Gen, but I don't think that is a real problem; (the RSV cables are longer).

First: the CV carbs on the Venture will not perform well with an open intake. The airbox and filter must be fully installed. Closed up. Second: if the jet block was cruddy, it is likely that the pilot circuits within the carb body are fouled, too. The pilot jet is notorious for being easily blocked. I suggest that you need to perform a THOROUGH re-cleaning of the carbs, replacing gaskets and O-rings with new. Attached is a pdf file for an excellent tutorial on cleaning the Mikuni BDS carbs.

Removing the CB or AM/FM or CLASS will have no effect on the cruise control.

Drain the carbs. There are drain screws near the base of each carb and they will drain via the hoses sticking out the sides. It's messy, and because of that, I might not even drain them, but keep aware they're full of gas still if you don't. Remove the fuel-feed hose (from the fuel pump) in the top-center of the carb bank. It is the only hose with a clamp. Use a radiator pick to free it up (carefully) if it is stuck. Pay attention to how the hose is routed. Gas will spill. Remove the four vent hoses. Notice the path they follow so you can put it back together right. Rem

What is the wire gauge of the negative, positive and starter cable on the RSV?

@cowpuc I knew DenDen from the Venturers Club. Indeed he was the First Gen Venture guru. I would be very interested in his info.

The SINGLE punch mark was indeed supposed to be done by the dealership when the stator cooling mod was performed. I have never seen TWO punch marks on the crankcase. I do not know what that is about. There was never a "recall" for the transmission fix. And it was not a warranty claim.

On the middle gear cover, the bolt/cap screw at the six o'clock position should have a copper washer under its head. The copper washer acts as a gasket to prevent oil escaping. If the copper washer has become work hardened (and it is once installed) it will leak when the bolt is reinstalled, even if reinstalled with the washer. The washer can be re-annealed (softened) and reused or it can be replaced with a new washer. To anneal the old washer, heat it to red hot with a torch and then quench the red hot washer in oil or water. It will now be as new (soft) and capable of acting like the gaske
