bad to worse

[SiP]

Ok - I posted on here about my snapped spark plug - the my snapped extractor in the spark plug hole.
I've bitten the bullet and taken the head off, it's now in the machinists getting cleaned and heli coiled - That's the good news.
Here's the kicker and if I had the ability I would indeed be kicking my own arse for being such a f@#*ing dimwit.
While stripping the inlet cam off I dropped one of the bearing cup washers straight down the timing chain hole !!!!!
There's no sign of it and fishing around with a magnet doesn't produce anything - please please please don't tell me I now have to do a complete engine strip. It's only little it might be OK?? is there any other way of seeing what's in the case?

ebay carb kit

By the way could someone (more knowledgable than me - ie everyone) check out this lnk for a carb kit and tell me if it's worth it/any good please.
My bikes an '81 H by the way.

Hey Sip,

Are you familiar with the Yamaha Online Microfiche site, if not, you can find it in the LINKs section! Go there, to the camchain section for your year/model, and you'll see the chain tensioner has this shelf as part of it's design, it may have fallen there, and with oil, could have just stuck!

You can pull the bottom tranny pan off without pulling the engine and you may find it has fallen down into it!? This is why they say to stuff a RAG down into the cam chain tunnel to prevent this!

Carb Rebuild Kit
Carb Rebuild Kit - Fits: XS650SG-SL (1980-84) stock Mikuni 34mm. CV carbs
Kit Contains : Push-in Float Valve assembly with O-Ring, Carb rubber passage
Plug & Float bowl Gasket 3F7. Made in Japan - 1 kit required per carb.


Part #48-1408 $12.00 USD /Kit

MikesXS has the above kit. Free shipping with order over $35.00! Unless you need to replace your jets and choke plunger, usually not, then this is all you really need, just be careful when removing the pilot screws so as not to loose the little washer/o-ring around the tip down in the tunnel!

GeorgeFix sells good stuff, but it's not all needed with a regular rebuild/cleaning! BTW, don't use the rubber pilot jet tower plug!

Sip, the washer in the sump won't be a problem, the oil pump is screened with mesh, the washer will sit in the sump recess, but if you wanna get it out, you only need unbolt the sump pan. 14 bolts. 77 bucks for carb kits, waste of money if the carbs are all O.K. especially if those kits have non-mikuni parts, but maybe worth it if the carb components are all seized and corroded - which won't be the case if the bike's runnin O.K. Individual mikuni jets are about 5 or 6 bucks each.

[SiP]

you guys r great, that's good news!!
I checked out mikes xs, and he only seems to supply for 650's. Does it not matter with the carbs?

[81xsproject]

no, those will work. TC know his stuff and MikesXS is a great way to save money on items that overlap models.

Only dropped one washer down the hole? You need to remove the oil pan first. Then, lay on your back on the left side of the bike with your feet towards the front wheel. Reach over with your right hand and put it up inside the open hole with your fingers forward. Chances are you will put your hand right on the washer. If you don't find it immediately, pat around with your fingers.

And you do want to get it out, don't you SIP?
Seriously, remember the "Anything that can wrong will go wrong" rule.

Good Luck with that.

Again - thank you. However you've sparked another question

good time to do the cam chain..

How can you do it without splitting the case - I thought the chain was endless?

Cam chain riviting tool

cut chain, link or wire chains together, feed through, rivit new chain.

btw, easier said than done, but not too hard

Unless you have your Bro-n-law assist you, then you'll be sure to tear things up! Just ask Randy!
