Another carb question. 72 xs2

[1972_XS650]

Hi all, I’m a new member. First time posting. I recently bought a non running 1972 XS650 XS2 as a project bike. I’m finding out that there’s not much to these motorcycles but I’ve got a lot to learn working on them unlike my last project bike a 2002 BMW K1200RS a lot going on in the bike but easier to work on.

My question is about the carburetor’s. First of all the diaphragm on the right carburetor has a small hole in it and needs to be replaced and the throttle cables need to be replaced. Replacement cost is about $230. New Mikuni carbs are about $500 with cable. The new cable has a single wire at the throttle and splits to two at the carbs. should I keep working on the old carbs or just replace with easier to adjust carbs? If so Which carburetors is everyone getting? And from where? Any tips on adjusting these carburetors is appreciated. Thanks in advance for any help.

Replace your Diaphragm"s with ones from JB industries. No need to buy new carbs. I assume you have a manual, if not thats the first step

I have a 2005 K1200S. If you can work on that BMW this 72 650 should be a breeze.

Until you fully strip and inspect the carbs we can't really advise. It's unusual but not impossible that the carbs can't be saved. On balance though it's more likely than not that you'll be able to fix them up. All the information is here in the carburetor guides.
