Thanks Nordie,
Have come to the conclusion that it's a case of 'do it yourself'.
So that is what I'm a gonna do.
If it works out ok I'll put up piccy.

What the heck is this, and why did it come out with all the oil when I just did an oil change?
I don't think it's supposed to be in the engine...it's a hard plastic thing. Feels a bit like a plug or something.
It may have just fallen into the oil pan after I drained the oil from somewhere else... seems a bit more likely, but I really don't know.

Plug from a cam bearing top, by the looks.

I'll second that. At least thats the closest thing it resembles that I've seen in one of these engines. Best check all the plugs are in at the top end or the old oil pressure ain't too flash!

Are you guys talking about part #16, here?
http://www.ronayers.com/Fiche/TypeID.../CYLINDER_HEAD

I'm supposed to go several hundred miles into the forest on Thursday, so I need to fix this immediately.
Can I glue it back in place or something? It looks a bit mangled, so I'm not sure how well it'll fit.

I'm going to go pull the cover now to see what else is missing.

I pulled off the valve cover, and sure enough, there was one of those caps missing.
...then I found the missing one stuck to the top of the valve cover. So no, that was not the part.
The thing that I found looks slightly different. Here they are together.


I've realized know what it looks like. It looks like the plug they put in the end of handlebars to keep water from getting in.
Weird, since I have MSR handguards in mine. I have no freaking clue how this thing ended up in my engine oil. I can only assume that it fell into the oil pan sometime after draining the oil before I put it into a container for disposal. No idea from where it fell.

While I had the cover open, I checked the valve clearances. .15 for both intakes, .18 exhausts, so all slightly out of spec, but close enough that it falls pretty far down the list of stuff that this bike needs. (Oh, how I loathe these carburetors...) It's not like I have spare shims handy anyway, and it looked like a lot more work to see which shims are in there now so I left them alone and will have to get back to that another day.

One question, though. The shop manual says that the side cover must be removed to measure the valve clearances. It seems like that's just so you can see a marking that says TDC. Can't you just tell by the position the cam lobes are in? I stuck a clean bamboo skewer the sparkplug hole just to double check... it seems like a lot of extra work and gaskets to remove that cover just to check for TDC?

Since you pulled it apart you probably already figured out that the valve cover holds those in place. No glue needed.

No you don't need to pull the side cover. All four valves closed and piston at the top just like you did it. But, IIRC, the XT has a dry stator. So pulling that side cover is no big deal.

Also this plug is plastic, not rubber.

Just been looking at the fiche of the TT600 vs the TT350.
The TT600 tank looks like it may fit...
Same strap for the rear and same style of front mount.

Looks to be about 11L stock.

Funny lookin plug there man, particularly with the hole in the centre.

It looks like the end off a cable shroud / cover. Maybe the clutch or brake lever dust cover, decompression lever cover at the head, clutch cable cover at the engine.

I'm lookin at replacing the kickstart decompression assembly with some sort of handlebar mounted manual de-comp lever. With the original setup I can't find the compression stroke so it's a PITA with every kick just a random "shot in the dark". I can get a much more predictable start without the orig decomp by squeezin it up onto compression, holding some force on the kickstart lever until there is the slightest of leakdown then kickin it.

However this non decomp routine just takes too much time given the compression of this engine and the slow leakdown due to good engine sealing.

But it seems to be about 2cm in dia.
I'm leaving toward a handlebar plug off something else.

I just push down until there's resistance, back to top, push past TDC, back to top and kick.
Wouldn't mind a manual decomp added for drowned/flooded bike situations.

86 XT350 resurrection

Can someone direct me to any posts relating to wiring on their XT350? I'm resurrecting an 86 model from off-road use back to dual sport duty and the lighting is is giving me problems.

Thanks in advance for any direction or advice.
