It would be real interesting to do a compression test with the new setup.

The scooter ran fine it's brand new. It had 600km on it when I did the bbk. I think stock jet is like 72it's s sealed carb. That's why I took the carb off my project scoot. I knew it would need re-jet. And like i've said about three times now, you can't see the stem in the old pic cause I just swapped the valves. Why rest valves on a head I'm not using?
No I don't have a flywheel tool. I'll snap some more pics of the fly wheel today and get them up. I'm thinking of just putting a stock head back on it. Will that help? How do I test for exhaust leak. Mind you I'm hearing impaired. That's why I kept putting my ear against the valve cover,but I couldn't feel a vibration on it like valves produce when they're loose...

I've discovered two new issues: 1: i have fuel in my air box 2: clutch contra slide is sticking. Bad! I pulled it back very stiff. When I let go it didn't move. I had to pry it back with a screwdriver. I was on the road. GOOD THING IS I know how fix that..but fuel in the air box???

if you remove the spark plug , and put a straw in the hole . Turn the engine over and find when the piston is at its highest point or closest to the head . When you get the piston all the way up see where the timing marks are , even post a picture .

Well I got the head pulled and tested the valves for leaks and notta. Getting fuel in the air box so I thought I had a bad intake valve. I poured parts cleaner in the port and let sit for about ten minutes and no leaks. So no I guess I tear the carb apart and check the float. Idk maybe the spark plug is bad. Can't get to an auto store too get a compression tester due to the weather. I guess I'm just gonna start shooting in the dark cause I'm completely out of ideas after that.

Timing is on like I said in the beginning.

Do you have any pollution devices on this bike. I'm sorry, I'm too tired to read over your thread and I can't remember exactly what's been going on. A vapor canister could be causing fuel in the box as could carb reflux from too big of a jet. If you take all of the induction components off and crank the throttle, if you see gas coming back out of the carb, that's reflux.

[Clank]

Negative on that PAIR. Float checked out operational to specs. Idle jet was obstructed and cleared. Swapped cam and plug. Have more to do. I'm half asleep and going back there.

when the piston was at its highest point where was the flywheel ?
