here is the new rockers/head cover

I'm a mechanic and I know Real, professional mechanics.
Unless you Know the job, have done it until you don't need a manual, you need a manual.
And no, filing the cam won't be okay. It's hard at the surface.
Get under the hard stuff, it's gonna wear.
They are polished, and file marks will eat your rockers.

The used engine idea was likely the answer.
Did someone here suggest you buy parts?

Thanks for the quick replies! It is not quite a case of jump then ask as the parts bike I got has sat outside for years and was given to me for free. I wouldn't go through the hassle of swapping the entire engine out without taking a look inside first. The parts bike top end looks good as far as I can tell. I haven't removed it from the frame yet to take off the cylinder. I will be ordering the Clymers manual today on ebay unless someone can direct me to a better place to grab one.

Is it correct that I will have to remove the clutch to remove the camshaft? If so I know I need a special tool for the rotor.

While I have both engines out I want to grab a verslagen tensioner, do the head plug mod, raptor petcock mod and replace all gaskets. I have been trying to educate myself as best as possible before I start ordering parts.

Thanks again for the replies, I really appreciate it. If there are any forum members around the tri-country area in Charleston, SC I would love to get together. Have a garage we can wrench in and many tools that I don't mind sharing. Cheers

I'm not sure if it has low compression, it tested at 105 cold and 110 warm a few years ago when I first got the bike. You can hear it run in a youtube video I posted in the first message.

The parts bike I found has sat outside for years, I was told the engine ran when parked but have no other information on it. I don't trust it. When I pulled the head cover everything looked great, when I pulled the clutch side cover the clutch is corroded bad so that will certainly need to be replaced regardless.

Thanks for the advise, I'm new to working on bikes. I understand I need to replace the head and cover in a set now, so I'm thinking of pulling both the engines, taking the entire top end off the parts bike and installing it on the bottom end of the original engine. I know this will be a lot of work but this is more of a hobby and I want to learn a lot about these engines.

I guess I could also just buy a used engine, do a swap and sell the other parts but I figured I would at least try to piece together one good engine from what I have first.

What would you do?

I would expect the cam bearing surface of the head to be just as chewed up as the head cover, and I would not use good rockers on a camshaft that is showing wear.

I wouldn't assemble the engine without taking the cam out and looking at the head to see if it is worn.

Thank you Dave. I think I am going to pull both engines, pull the top end off the original engine an take a look at the head. Then probably swap the entire top end. I know I'm going to need a 32mm socket for the front pulley and that special clutch pulling tool. Will I need any other special tools?

Ordering a new gasket set, clymers manual, and clutch puller tomorrow.

you don't need a clutch puller, comes off quite easily.
I forget witch socket you need with the clutch, but you need a 30 and a 32.
If you plan on pulling the rotor, there is a special tool for that.

so keep the cover and head together, they are machined to fit.

I would use the other engine as is, it maybe seized, pour a little atf in the sparkplug hole in case the rings are stuck.  All these these things you are about to get into are why people fail and ruin an engine.
