Need 78 Standard Fuel Petcocks

[bs78xs1100]

First of all - love the site! Have learned a ton just by reading through the site.

Now - Just bought a 78 XS100 E Standard. It's in the shop getting the carbs worked on. I've been told that it needs new petcocks and some kind of a stem within the carbs. My question is... is there a vendor that anyone knows of that I can contact (that has a lot of 78 parts)? I live in Ohio and I REALLY want to get my bike back and get out on the road! Any names, numbers or websites will help!

Thanks in advance!

Check with Anreas Wiess, a member here. He has a lot of XS11 parts for sale and seems to be adding to his collection all the time.

I did a search for him and nothing came up. Do you know his user name?

Thx, B

Oops

I had a typo in his first name. It's andreashweiss. Sorry Andy.
He is easy to find here.

I'm having a hell of a time finding these anywhere. Anyone know of a shop that might have them?

they don't have OEM's, but they have like generic petcocks that'll work on most bikes, and they sell adapters for the 78 XS11. Plus, they have genuine on and off positions, so you can do away with the whole vacum on switch, and avoid possible leaks etc in the future. I'm planning on replacing my petcocks with these eventually.

Good luck bro,

Kris

You also might try Old Bike Barn.

By the way, what part of ohio are you in? I'm in Westerville, just north of Columbus

Was killing time so I looked at the Old Bike Barn. They do have rebuild kits and some univeral kits also. Good luck.

Well - going to keep my bike for a long time. It's a really nice bike! So - went ahead and ordered new ones from Yamaha. Normally wouldn't spend that much - but I got sick of trying to find them. And I'm not all about adding adapters and/or buying used. Figured I might as well do it right if I'm going to keep the bike. $80 a piece though! Ouch! I'll just have to ride her in a few extra days to save on gas!

B. I rebuilt mine last night with some homemade gaskets, and so far, they are holding. I took a piece of 3.2mm thick sheet glylon (inert plastic), and a set of leather punches. I will try to post a pic/how to if there isnt a puddle under the bike when I get home(could make a few more, have some material left.)

well, it kinda worked. It didnt leak in the off position, but the gasket is all one thickness, not like the OEM, so it takes a bit of force to turn it. Also the holes have to align perfectly, so trying to get all 5 holes punced into a small disk without damaging it while punching out the holes. Drilling it worked better, but then the holes needed alot of xacto work to remove the burrs left by the bit. I tried to just drill the reserve and fuel feed holes for ease, but it needs to sit against the back of the petcock body to seal properly (because the center feed hole isn't raised like the other three).

All in all it works, but it wasnt pretty. and I am not to confident that these seals wont start to rotate in the petcock. They are held in place by the petcock outlets, but the combination of turning the petcock, and the friction will tear/destroy it soon. Inspection of the gasket after only a few turns showed marring on the gasket surfact. Not to mention I havent tried them on a full tank. I just put a gallon in for the testing. It would suck to find out them dont work on a full tank.

Probably cheaper and easier to just buy the parts (I ordered them this AM)

I feel better - thanks! Those are the the kind of problems I didn't want to run into. Nothing worse than wasted time and frustration.

Good luck!

ps the part # was KL185100 from oldbikebarn.com for my bike. it comes with all of the gaskets for both petcocks and the vaccumn diaphram to rebuild that octapus thing for $32. If you only need the 5 holed gasket, they have a cheaper kit.
