Perplexed-Need Help X 4

[MrConcdid]

I have 3 in right now myself
1 a 200e leaky valves no compression
2 200es intake valve is hanging open
3 200es cylinder is rusted, piston moves but slowly.this

Yours may be a 2 ok bikes becomes 1 really good bike and the other becomes parts bikes.
You dont have to rebuild them all. Weigh out your options.

I'm going to cut the chain off today like 350 said and see what happens. Whatever it is that's got it locked up has both the 200s locked up. The 2 250sx's weren't hard to get unlocked but of course, they don't have chains so we'll see.

So... a little update

Slow but progress but first see why I am so interested in these bikes:




See how easy it is to read the engine number? See how little the sprocket is worn? See how little wear is on the foot pegs?

I cut the chain off today and front sprocket was rusty but moved freely and I verified neutral. I put an 18 inch stilson on the axle and it moved like butter (eventually).

I was going to remove the engine and according to the manual-the first thing to take off was the exhaust. Nuts came off very easily so I thought "something is not right", couldnt figure out what so I sprayed everything with blaster and will probably remove the engine tomorrow.

I opened the exhaust valve cover and everything looked new. I took the cage off the rotor and everything looked very rusty.



And yes, I tried to turn the motor over and "nothing"

It"ll probably come out tomorrow.

Thanks for the help!!

So strange that so many parts look good and so many look trashed. It’s like it was squirted with some sort of corrosive liquid in spots!?

[patriot1]

Yes atcmatt: based on suspicion and knowledge of shortline-rat piss is the guilty culprit to blame! What's perplexing is how much and locations. Might have been beer drinking rats? How did so much get into the recoil? How did they nest up in the enclosed and sealed drive chain area?

These bikes have a "crank case cooler" (probably not the right name) that I am going to look at today. It's a 1/2 inch hose that runs from the bottom of the engine to a oil filter looking thing. Not doubt rats could have got in there as well.

One more thing that I find odd-I have not noticed not one chewed wire anywhere on this bike.

That’s because the wire sheath is pre vegetable coated crap that’s used on the newer machine’s .

Some of you know that I am blessed enough to be able to use an old Vo-Ag school building to work on my projects. Around the room there are old wooden toolboxes all labeled ie: wood working hand tools, cold steel, arc welding and:

So update:

Going from a Haynes manual and I don't like it as well as a Clymer to pull the engine out. Haynes is small print and hard for me to read.

Everything went well and I could not believe how easy all the bolts came out. Everything until I went to war with the exhaust.



I won

Next the carb just because it's interesting:



Slim shady

Next the engine is out!



And crusty as hell!

I should have stopped when i got it out, I really needed to go home but I couldn't wait to see what was inside so I kept going until:



I screwed up the screw on the right. Then I decided to do something else.


Shortline: I can tell you have way more experience at this than me. What should I expect next?

More on Sammy to come.

I use one of these on any screw thats been in there for awhile, spray it with pb blaster for a day, hit it with a . it might mess the screw up if its really stuck but usually the screw comes out. jim

[patriot1]

I tried with one yesterday Jim. Didn't work so I decided to let it soak. Hopefully will be able to open it up today and see what I am working with.

[ATC King]

For a stripped Phillips/JIS screw, you can cut a slot in in, then use a flat tip in a impact driver.

Don't cut too deep or the head will split and make sure to cut square so the tip doesn't cant out.

[patriot1]

The manual say "remove the dowl pin" I don't see one. I can't get the rest of the pulse generator out (??Is that even what it's called???) What am I missing?



Anything else?

[shortline10]

That whole advancer pulls off the camshaft , might be stuck .

[atcmatt]

JIS screw drivers are the best. Impact series have saved me so many headaches. They are worth every cent and more!
