Long story short. Bought first ATV. Finally got to ride and after 15 minutes noticed smoke coming out under seat. Found oil leaking by the front right cylinder retaining bolt. Hoped it was just loose. Nope it is stripped. Will not tighten. Was thinking if I have to take off the whole top cylinder to repair. Would I be better served to take to a shop and have them rebuild top end and repair bolt? Anyone know what that might cost? Roughly?
Suggestions appreciated

ok, is this the long skinny bolt on the right side ?, if so ?, odds are, it's broken down in the lower case, they are bad about this.

Yes, it is the front right bolt. Feels like it almost wants to tighten, but then just keeps turning. I didn't notice the leak when I bought it, but should have known something might be wrong, as it was low on oil. I changed oil and filter and cleaned carb and finally got it back together yesterday. Was happy and ready to ride. Then this. I am afraid I made a bad buy. But other that this leak. It seems to run fine, shifts, goes in gear fine. Just not sure about how hard it is to pull the head and install a helicore. Or if that is my only option.

if the bolt broke off down in the lower case ?, which like I said..is very common on these stupid trx350 ranchers !!, then you will have to drill it out, and yes, you will have to pull the top end/cylinder in order to get to it. I have seen tons of these break off, been there, done that..lol.

I don't think that it is broke off I can back it out and can reinstall it. But I think that is really a mute point, I think the threads it seats into are stripped, which essentially means the same thing. Pull top and install a helicore. Anyone have a ballpark cost to have this done?.

your not following me. if the threads are broken more than half way on the bottom of the threads on the long bolt, and the bottom half is down in the lower case ?, then you won't ever get it to tighten. this means, the top end has to come off, and the broken bolt has to be drilled out, and then re-tapped, my point is spot on, I've seen this a time or two !. now, if the threads are stripped out on the long bolt, or down in the lower case ?, then this will require work one way or the other depending on which is bad ?, if bolt ?, replace, and you won't know this until you remove the bolt, both of them to be honest, so you can see how long the good bolt is. if the bolt broke off down in the lower case ?, it will require drilling and tapping, or heli coil, and I have no idea what this cost ?. I just drill the broken bolt out, re-tap down further in the hole, because there is a tad more hole below the threads to make new threads, but not many.
