I'm thinking about ceramic coating and maybe heat wrapping the exhaust, then maybe heat shielding on the bottom of the tank since it seems to be the exhaust side that boils.
I've had the fuel boil and it's a little unnerving, you're thinkin, if this thing blows there goes my sex life

Shielding is good, fan is better if you can work it out with the electrics, it'll run all the time in those conditions though. I've never been a fan of wrap on a dirtbike for rust reasons but I hear it helps. Are you running a check valve or straight hose. Many of the caps have a check valve installed inside of the cap, toss it and the stubby little check valves. Run the plain old hose into your steering stem and the pressure issues will go away.

I do like the idea Freak. I have had one day where it was boiling hard enough to pressurize even without the check valve. I thought of rust too but that was why I was thinking of ceramic coating first. Gas burns like hell when applied in liberal doses to your crotch. Had lots of slow going Friday on Golden Spike trail in Moab.

Don't resleeve, there is no sleeve oem. You want it replated. It is the better option.

The oil should drain instantly....otherwise you may have a gopher or tribble living in there....

A long time depending on temperature and pump wear.

That's one for your KTM

Advice

So I installed my head and instead of applying oil to the inside of the nuts as stated in the manual I used my finger and just smeared small amounts on the threads of the studs. Torqued down the head bolts to proper torque and all was fine. Then I noticed a little bit of oil squished out of the base gasket and head gasket after it was torqued. No doubt the oil ran down the studs and made its way there. Will this destroy the base and head gasket? Should I tear it down and use new gaskets?

I often smear grease on paper gaskets and wipe them off good, they swell a little and next time it'll come off easier. Hasn't caused issues yet, I wouldn't worry about it.

I would consider a re-torque of the bolts once you've heat cycled the engine a few times.
This requires backing off the nut and running back to torque again, not just putting the tension wrench on it and checking its still tight- bad practice.

I was wondering about re torqueing and will. Another question. I have not installed the camshaft, top cover, or right crankcase cover yet and it seems to have hardly any compression. I can turn it over with 2 fingers darn near. New piston and rings. Should it not make compression even with no cam or top cover on yet?

Was the head done up also? Re-valves and seats etc?
Is the spark plug in the hole?
Assuming all is good up top, just keep putting it all together.
Once run in, try and turn it by hand..

Assuming the head is fitted with no spark plug and no cam it will be easy to turn over.
If the head is on and torqued down with spark plug installed you will not be able to turn it over with two fingers.
With cam and rockers in place you will need significantly more effort turning it over (even without the plug installed) as you will be compressing the valve springs.

Hope this helps.
