Seeing as the push rod appears to be bent, I wonder if it may also be mushroomed on the end. That may prevent it from sliding through the push rod bushing. Although a bushing isn't shown on the diagram above, I'll bet there is one on the bike. I haven't found any diagram that does show the...

Manual suggests re-installing in the reverse order.

There are a couple on Ebay right now, but the prices are up there...

The ones from Partzilla are the new style locking nut. They are not correct if you want to keep it original looking. The original style are tough to find, but do come up on Ebay occasionally; I snagged a few for cheap a month or so ago. If someone does come up with an alternate source, it would...

Columnar basalt. Devil's Postpile here in California is comprised of the same rock.

This part manual lists 256-12231-00-00 for the XS1, and 256-12231-01-00 for the XS1b, XS2, and TX650. 256-12231-01-00 is also the number for all later models. The "01" digits indicate a modification of the original part, which suggests some change was made. It's possible the change was small...

I searched some threads on cam chain guides and found some information suggesting that guides for "early" (70 to 73?) bikes are different, possibly due to clearance issues. Online parts sellers like Partzilla, CMSL, and Mike's indicate one guide for all years (not that I trust these sources...

Currently, there's several NOS brackets for under $30 on EBay. Part # is 256-83519-00.

Any update on your progress on these?

I have 2 brand new Yamaha air filter elements (533-14451-00). I believe these fit 1974 and on. Thought I'd offer here first; $60 plus shipping for the pair OBO.

Have 2 new Yamaha air cleaner elements (533-14451-00) that I bought and never used. I believe these fit 1974 and on. Thought I'd offer them up here. $60 plus shipping for the pair OBO.

Black bits are likely from the cam chain guide. Best to fix it now with new tensioner and cam chain. Had the same situation with one of my bikes. Because the engine has to come out to do this, I took the opportunity to do a whole top end refresh. There are good threads in the Tech section on how...

Been looking for a pair of early original petcocks for my XS1. Found a set off a bike being parted out at a good price, so took a chance on them. They turned out to be in decent condition, but were pretty gunked up inside. Looks of soaking, cleaning, and polishing, plus new gaskets. They look...

I have one if you need it. Message me if you want it and I can put it in the mail to you.

I may have a spare 90 degree fitting. Let me check.
