Tore Apart the 1000S Engine Tonight...

[Nessism]

...and I'm two for two in purchasing S's that have been hot rodded.

Cylinder bores measure at about 76mm (stock is 70). Pistons are MTC. Anyone venture to guess on compression?

Cams are ?? Lumpy enough to require profiling of the head at the valve buckets.

Lastly, the intake valves are oversized. I have no idea what size but they look pretty big.

The PO just installed a new starter clutch, which made a nasty click noise the first time the engine turned over. Obviously this thing has good compression.

All this stuff is kind of fun but honestly, all I want is a stock engine. Going to most likely sell off these parts to fund a stock rebuild.

Oh, and notice that O-ring. Can you say oil leak?

Lucky you all those good parts for FREE!! You should PM Bruce & see if he will trade you some of his stock parts from his 1000. Ray.

[tkent02]

I will.

[Nessism]

I will.

Tom,
What did you do with those parts from my last engine?

[tkent02]

Set them on the shelf for now.
Could use that head with the bigger valves, does it have VM sized intakes or CV sized intakes?

Hi Ed,
If no one is interrested, i can trade stock parts + $$.

It's a 1980 head so it has the CV sized ports. I'm going to pull the valves out today and look at the ports to see if anyone has gone in there with a grinder.

Geez, a 1176cc GS1000? Is that streetable or is it dragstrip/roadrace only? I'd assume you'd need aftermarket sleeves to make this work? And how common was it to go this big back in the day?

I am definitely interested in that head, how big are those valves?

[67fire]

Interested in the cylinder and pistons.
I also have stock 1000 parts.
Might still have a stock head as well.
Do the cams have a stamping on the end? I might wish to have them also.

Pulled the valves out. Intake valves are 2 mm oversized and backcut. The valve guides are nice and tight - the odometer says 6000 miles.

Jim,
A stock 1000 has enough power for me, it's hard enough already keeping the speed down. Plus I'm hoping to save some money on the build by selling off these hot rod parts - stock parts are cheap in comparison.

Put that engine back together and slowly walk away.
Sell it complete and find another engine.

thats a lot of carbon /oil buildup for only 6k
