Mystery Engine

Thanks Jay. So someone had these cams ground by who knows. I don't know the lobe seperation or anything about them.

I will look at them again more closely.

The guy that owned the bike when it was raced was a kawasaki mechanic for years. Both mechanics at the shop usally had their engines built by sonny that is no longer with us.

I really didn't want to tear the engine down but might have to. It has compression out of this world.

The guy I bought it from told me it was a built engine but I didn't pay him no mind as I was wanting other parts off the bike.

Les. I lost the PM. I'll think about it. Roy

Why two head gaskets? I'll have to check the cam chain tower and see what type it is. Roy

If it is a 418 Andrews, it will have a lot of duration for a street motor. Some of the early cam covers had an X cast up underneath them. High lift cams would hit them if they were not ground off. Some used the double cam cover gasket to solve it.

Thanks again. This bike has all chrome covers from Browns Plating. Roy

could be a ape hanger

Put a degree wheel on them for valve opening/closing measurements, may give you some idea on the duration...

I'm going to fire the engine.

I couldn't tell if the engine had a cometric gasket on it. How can I tell if the engine is bigger than a 900cc. Can compression tell?

I found a cam cover the has the X's ground off. I don't think they were done by hand! :huh:

I might just install the cams in my 1075 engine. I had to sell my 3X cams last year when I was broke and this will put me back on track. I got $255.00 for the 3X and only paid $175.00 for this bike. So that will put me ahead a little.

I didn't find any more markings.

That's got to be worth 6 HP

Point the lobe straight up and get a photo from the side. The profile view will give a good indication of ballpark duration.

Will do. I hope to get a chance to get the bike wired today. I done shop lighting and lawn tractor starter last night. Roy

If the pistons are aftermarket cant you see if you can read the numbers off the top. and find out what they are.
