So I have a pretty decent leak at the head gasket. I tried retorqueing to a higher torque all the bolts per a thread I saw here, but it's still leaking a little bit. I also need to replace cam chain guide bar. I know a mechanic, who I trust and highly regard, who will do it all for me, and do a valve job while the engines off. I'm tempted to just let him do it, but I'm also tempted to do it myself. I'm confident that I can get the engine off the bike, and replace the gasket, and cam guide, but my worry is that I won't be able to tell if the valves need adjusting or if anything else is wrong. SO I guess my question is how hard are these things to figure out. If I get the engine off and start looking at things with a good shop manual and you guys help, can I make it happen?? Opinions...

It's all pretty easy if you read the manual........and all you can do is screw it up.....then you do it again and pretty soon your an expert.......

That being said, which manual do you guys like better haynes or clymer. I have the clymer, gets a little confusing.

If you just read the manual without taking it apart it would appear confusing......If you watch how things come apart you will know how they go back together......and you really need an electric or air impact wrench and a hammer impact for the clutch spring screws.......
And if you leave the pistons in the bore and just pull the pins you won't have to break it in again......"if it ran ok before hand"......getting the front chain guide in straight is pretty important too.........

If you pay a mechanic everytime you need work on the bike, it will get to be very expensive. These bikes are not difficult to work on. If you want to learn how bikes work, then this is your chance. You need to spend some time reading the past threads on the engine forum. Many of your questions have already been answered.

Yeah I'm starting to see the light. I'm going to order the gasket and the cam guide bar next week then, get the engine off the bike. Anything I should order while I'm at it that tends to need replacing? My thoughts right now are to get the engine off the bike, get the head off, and then decide whether or not I want to try to do a valve job, or take it to a machine shop. A reputable bike shop in town will do a valve job if I bring the head for 100 bucks. That may be worth it as I don't have the tools necessary to do the job (or really even a decent workshop) and buying them would almost cost that. I agree retired gentleman, that you'll spend a lot of money if you pay for a mechanic every time, and I learned that lesson the hard way. Pretty much everything else on the bike at this point I've done myself, so maybe this needs to be that way too, although professional help is sometimes nice.
Thanks,
John

You should do a compression test while the engine is still running. That may tell you what needs to be done inside the engine.

If your head gasket was leaking then how come your compression test was right on, and what is right on?

it's quite possible to have a oil leak and still have compession or a compression loss without a oil leak just depends where it's at and what remains sealed
