If you ride it and the head is leaking, it's gonna blow....
If you ride it and compression is really that low in the one cylinder, its gonna blow...

If your tester is working properly, you either need new o-rings or you need to rebuild (at least top end). Don't wait until you take out your cylinder, cases, and crank, then it will cost you 5 times as much to fix. A top end is relatively cheap...

i jUst have a hard time believeing that i would not even know the comp is so low i feel if i put it in the water and it runs ok then i should be fine i may be wrong but thats what i would think

 

[Matt_E]

Ok. Let us know how it turns out.

 

[lcgordon]

Ok i just did the wd 40 thing no change maybe 5 psi lower so i guess im gonna pull the head anything i should know just undo the bolds right

 

[Mdavies_02]

Yea, make sure you have a head gasket in hand, and remember to torque those bolts to 18lb if your running a non girdled head.

 

[Matt_E]

Loosen all head bolts and the girdle nuts.
Remove bolts and nuts plus washers, then take the head off. But be careful to pull only on the head and not the cylinder. (I don't recall if the Wammer head uses girdle studs only or a 2-part system like the Riva head)

 

[lcgordon]

ok thanks ill try that and look

 

[lcgordon]

wow this is gonna be harder than i thought cuz my pipe is in the way of a few bolts

 

[Matt_E]

I assume you have some sort of drypipe that wraps over the top of the head?
If so, you'll need to remove the chamber.

 

[lcgordon]

gotta take the pipe off

 

[lcgordon]

Well i got the head off and the first pic is before i took it off it has a hole by the carb is there supposed to be a bolt there or not. The third pic this thing inbetween the cylenders is loose dont know what that is im guessing it needs to be tightened up. The Fourth pic is a white milky substantce guessing a water and oil mix. And the inside of the cylender looks like its all moldy is that ok? The Fifth pic is of the cylender and piston the piston looks like it has hard black depost on top and the cylender walls maybe have scratches not sure. The last pic is of the head and the o ring that fell out. Well you guys take a look but thanks alot for the help in advance.

Looks like you got some scoring in that one bore, but it might just look that way. Run your finger around the bore and feel for scratches. The entire bore should be very smooth.
The lose thing is the sacrificial anode. You can tighten it back up or take it out, it doesn't matter.
The missing head bolt is a big deal - that could have caused some cooling water to leak past the o-ring into the combustion chamber.

 

[lcgordon]

I think there is som scratches also does the head look ok? If it was not ok would i be able to know?

 

[lcgordon]

Ok defenatly scratches needs rebuild for sure i guess so what is the steps for that?

 

[Matt_E]

As long as the dome surface is smooth and doesn't have pieces embedded in it or looks all cratered - the head is likely ok.
You need to check out the scratches on the bore. That is not ok and could well have been caused by a leaking o-ring. The intruding water can wash the oil film away.

 

[lcgordon]

well i sunk my ski last time i rode it so it was all filed with water.

 

[Matt_E]

Ok defenatly scratches needs rebuild for sure i guess so what is the steps for that?

over sized pistons and bore & hone.

 

[lcgordon]

Do you know how much that would run

 

[Mark44]

Do you know how much that would run

550 bucks about. with base gasket piston rings fitted and new wrist pin bearings. Ask me how I know.
