Hey all, searched but not a single hit on the xt600sc (California emissions model). Surely I'm not the only one?

I'm resurrecting a 1986 xt600sc, parked with fuel in the system over 20 years ago. I'm a bit rusty myself when it comes to carb work but Carb cleaner and patience seem to be winning on the hard parts. All of the o-rings and gaskets pretty much disintegrated and need replacing. I gather oem is the best (or only) source for these now?

Also, the air intake and exhaust system are stock, but the original charcoal emissions canister had been removed and some of the carb ports / hoses capped off. I'd like to get this bike running without the emissions junk if possible since I'll be using it off road with a Clarke tank (petcock only, no emissions outlet bung for the tank to canister pipe).

Curious what effect if any omitting the emissions equipment will have on jetting, etc.? I've seen references that the standard xt600 primary main jet was a #130, but the one I pulled was #125? I wonder if the sc model carb came with it or it was installed later, possibly to compensate for the lack of charcoal canister... anybody?

I imagine this isn't the first time an xt600sc lost it's canister, so perhaps someone has a suggestion on which primary and secondary main or needle jets, clip position etc. will run best on this carb with the emissions bypassed, and whether simply capping off all unused carb ports is standard procedure or if any need to be vented to atmosphere?

Thanks much, forum has been a great help already!
