Just need to check the air gap on the pickup coil.

What is your elevation? At sea level and +4 on the timing to be safe you should run 21cc domes on pump gas.imo

Do you have your slides in the right cabs? Did you switch them when you had the bike apart?

17cc dome is to small for a 68mil bore at sea level.I would not go any smaller than 20cc on a 68mil bore at sea level.You will need to trench your cases for that crank.

I broke piston skirts with my short rod motor,but it did rev quicker.Not worth it in my opinion,i like the reliability of long rod motors.

I use real fine steel wool.

I would not go any smaller than a 20cc dome on a 68mil bore at sea level.

Check your impeller,do you have good coolant flow when you rev the engine with rad cap off?

NGK caps is all i use.

If you have trinity domes then that is your problem,i had 185 psi on each cylinder backing out plugs with trinity domes running alky.Switched out domes to some custom cut ones and sill had 185 psi, changed nothing else and problem went away.

Just make sure everything spins free after you torque the bolts.

I have ran a cylinder like that before,i chamerd the edges and ran it.That far down the cylinder is were it supports the piston when the rod changes direction.Mine was damaged from a broken rod and was a little bigger chunk.It lasted for a long time and it never failed because of that broken piece.I would try it but,it would be best if you didn't have too.I am always tearing my motors apart so it wasn't that big of deal for me.I REALLY liked the port job on my cylinders is why i ran mine.

When in doubt put new spark plug caps on it

I have also learned the lesson the hard way about trinity domes on my cub,the same problems windy city had.

You should not have to go past .080 to clean up your cylinders unless they are really messed up.You should never go bigger than you have too.My buddy had 100 over and it ran good but had to get custom domes made too set the motor up right.It did not seem to overheat but the bike was only ridden at the coast.

Make sure you have the black tube in place that goes inbetween the carbs.

They would work depending on what fuel you want to run,you would need race fuel or alky with a 21cc dome on a 68mm bore.

You should go to a cpi,shearer,rocket,vito's fat bastard or the new sniper pipe,that will let your motor rev out farther and match your carbs better.I run a 15-41 gearing on my cub on alky with 22 inch tall tires.I would change the pipes and then figure out your gearing,what kind of riding do you do with the bike?

You can run pods with no problems with good outerwears and a little common sence.

You have to pay to play,it cost money to go fast

I had my 4mil cub decked and ported,it gave it 7 more pounds of torque and only dropped peak 3hp and gave it alot broader power range.Did not fall out of the pipe near as easy as it did before and ran alot faster 60ft times.4.17 300ft 240lb rider with a non lightend stock frame.

To stay on pump gas with that bore you might need 23cc or 24cc domes.
