Just scored another 1100 motor

Posted: Tue Aug 29, 2006 1:47 pm

This past weekend me & Laurie went to Grumps house in Nor Cal to pick up a motor I purchased about 6 months ago.

I do not know what is going on inside this motor so I am going to open her up and prep her for an 1123 kit.

When we put the motor in the truck I noticed a few things out of place right away besides the covers missing that is. What can you see out of place at first glance on top.

This motor is going into my latest project that I still need to go and pay for and pick up. It is gonna be awesome looking and hopefully it will handle good too. It sure will be trick though.

Its missing a cam chain?

Score one for yourself Nick, cam chain "B" is off the cam and hanging there off of cam "A". But there is one more multiple thing out of place too.

The cam bearing cap between the one with the tach drive and the exhaust cam sprocket is missing.

No, it is there Scott, you can see the top of the cap that lames always try to tighten up when their valve cover leaks and they strip it out so a guy like me has to do a thread repair.

Odd... I have a motor with those same blue rags Laughing

Cam chain B is off too Laughing

Posession is 9/10 of the law.... roflmao

From all outward appearances that motor is probably in good shape, though the #4 exhaust valve stem is oily. Pop the head and the pan off, check the valves and lap em, do valve guide seals... if everything else looks cool that motor should be ready to go... hope all is well with the tranny. Wink

I threw a towel over it for you Ray Wink

There's no upper tensioner there either.

Good eye Randy Cool

I have a new tensioner and two new springs thanks to Tom Strasser.
The head cap nuts were loose is what I was talking about being the other thing out of place but a tensioner missing is bad too. I did not even see that missing until I saw the pics that Gene put up.
Thanks Gene, I will see you in a little while again.

I can vouch for Randy's intimate knowledge of the whole Cam Chain and tensioner mechanism - he was up close and personal with it this past June...

That's awesome Ray!

I hope the internals are massageable and will be perfect in the shortest time possible!

Cool

I was wondering about that at first glance.

That is nothing compared to what I found after removing the head.
The number 4 piston was at BDC and the water that had sat in there for years was dried into rust fuzing the rings to the cylinder walls. This motor is shot if I can't get that piston out.
I forgot my good camera and was only able to take this picture with a shitty camera.

Here's a better look at that cylinder Shocked

Cool a 3 cylinder!

Wow Gene, you are a magician or a wizard or something because when I left your house that was a four cylinder motor. Confused

OK OK I'll put it back Smile

I'm starting to think fresh plugs and a can of Seafoam wont bring that motor back to life Shocked

I'm inclined to agree.....but maybe deep creep from seafoam might aid to get that piston free....... Idea

What about some heat?

Posted: Wed Aug 30, 2006 9:25 pm

I think it is going to take me ripping the whole thing apart splitting the cases and beating the piston from the bottom.
What ever the case may be and how I get it apart the fact has now arisen that I have to buy a Wiseco piston kit again because the cylinder will have to be bored to clear away the rust damage if it is possible. I have seen some cylinder damaged from water before and it was nothing nice.
The head came apart pretty easy and it is plain to see that she was in desperate need of a valve adjustment. The #2 & #3 exhaust valve seats are carboned up real bad and will need a touching up with a seat cutter but the rest of the seats are ok as far as I can see. They should claen up easy and then I will just lap in those valves.
I forgot to take pics as I was taking it apart, sorry. I get into what I am doing and don't think about taking pics.

I need an 1123 Wiseco Piston kit for this motor and have to wait a week to order it.

If you want to consider another approach to splitting the cases I have one for you. I used this to free up a rusted pontiac engine to rebuild. First soak w/ a good penetrating oil. You can hit the cyl gently w/some heat since you are apart. When your satisfied your done there, put the cyl head back on.I would use the old gasket.All spark plugs are out.Now go to the cyl slightly down from or at TDC. It doesn.t matter if this is the rusted cyl or not. I used a fitting for my compression tester, It screwed into the plug hole and had a quick disconnect for the gauge on the other side. That fitting also fit my air compressor . Now connect compressor to the TDC piston . Say you use 100psi. 1100 piston has almost 6 square inches of area. At 100 psi that's 600 lbs of force pushing down . The engine I broke free sounded like it exploded when it broke free. No hitting rods w/ bfh or anything else. The piston rings take the brunt of this abuse.I was a wuss and wore safety glsses though. good luck

I just scored another 1100 motor too!
Difference is that it's stuck in a late 80's GSXR 750 and it doesn't have any stuck pistons! Laughing

That and the fact that it's a Zuki motor!
Should be an interesting project, has a later USD front end and newer wider wheels.
I may just be a squid on a crotchrocket for a bit when this gets going! Shocked

No worries, my F won't lose it's rank in the stable!

A popular method of freeing up siezed piston's is Diesel Fuel. Fill each cylinder with Diesel and let it sit for a day or two.....you might be surpised....but then again, that is an extreme case.

I just ordered a new "B" tensioner from DSS, it should be here in a week.
The chains appear to be really good. It was difficult to remove cam chain "A" from the sprocket which is a good sign to me of a tight chain.
I will know about the primary chain when I open the bottom end but I am willing to bet it is within tolerance.
I think this motor was neglected to the point of no start and then left to sit somewhere forgotten. So far I have seen no sign of catastrophic failure, only a carbon build up on the exhaust valve seats from no adjustments. We will see what the story is when I split the cases but I don't foresee any major malfunctions, just a stuck piston.

Posted: Thu Aug 31, 2006 5:03 pm

Yeah, it was left out in the rain, that's the cylinder that the exhaust valves were open on when I looked at it.

Hope the crankcase isn't full of water... I put more Seafoam in it...

Why DSS?
You can still get then from Honda can't you?
I know I can. Just takes a few weeks is all.

Because it is cheaper and faster to buy the Honda parts from DSS in the UK than it is to buy the same parts here from Honda.
Upon further inspection I found that both studds are busted off the #2 exhaust and the PO tried to get one out but broke the bit off in there and it is going to be a nightmare to remove.
This is turning into something I may just regret.
