I rebuilt my 750 at about 70k miles and it needed to be bored. At less mileage, maybe not? You have to measure the cylinder wall wear.DLP wrote: So I have done a compression test and I think I might need some rings, how often is it that the pistons will have to be replaced also or is it just a given to do it all, I have done a little looking in to it and it seems some of the parts might be hard to find or come by

If its been sitting that long Id be willing to bet the oil is really funky which is not helping the rings seal any either.
Before you get it back together maybe throw a little sea foam in the oil and crank it over several times to get it run through the motor.
Then change the oil and filter to see what it looks like,Then put it back together and see if you can get it running.
Sea foam makes a really good carb cleaner also,just dump a big can in the tank and run the wheels off of it to see if it helps.
Still recovering,some days are better than others.

As far as adjusting them I just check the ones pointing away from shim on both cams,spin it over with a wrench and check the others.
Keep a list of the clearances then if you can get the motor running/rings freed up you can always swap the shims if the rest of motor seems solid.
