That tubing is made for smoke fluid for gas powered R/C model aircraft, the tubing is heat resistant. I use this tubing in my R/C Model plane.

Well After intensive searches and testing I got nowhere so I just went to autozone and bought a repair manual and it seems I was doing the test wrong Now it shows 7.6k resistance on the coil which is in good shape. I probably should of mentioned that the coil has 2 spark plug cables in just the 1 coil and to check resistance you must check in spark plug cable to cable :S and now I have readings!

well recently I got a free 1980 CM400A 9k miles with (auto transmission??? Huh?) well I tried to start it and no go I changed the oil, oil filter, spark plugs, fuel,and cleaned the carb the hell out of it because the jets got clogged because it was sitting for about 4 years outside just rotting away. Anyways I did got it started for once and idled just perfectly but when I turned it off it wouldn't start again at all. I tried to test my coild and not sure of I did it right as I set the multimeter to 200 ohms setting I get 02.6 ohms in small wire that powers the coil and then set to 20k ohms on the spark plug wires with cap removed ofcourse I get nothing the number doesn't change it just says 1 :S can the coild be bad?

your video is set to private, so we can't see it. Also if you hear constant clicking when hitting the starter button it means your battery needs a recharge because the charge is low now.

it is not necessary to adjust the valves after adjusting the f/a ratio as the valves are there just to help in intake and exhaust. The air fuel ratio is to adjust how much fuel and air enters the cylinder intake valves has the role of opening to bring the fuel/air in the cylinder and sealing to allow piston to compress properly same goes with the exhaust it opens to allow piston to push burned fuel fumes out and closing to provide a seal to allow piston to compress the fuel/air.

so it does sound like valve gap is a little big? or what is you opinion on that sound? sound comes from the top on valve cover by exhaust side so probably could be the exhaust valve gap is a little big and it may be banging the valve hence the banging sound

Well, I keep having this tapping sound when I start the engine and stays the same level even when cold started. Sound will not change with engine temp but rather sound much faster tapping with engine rpm increasing. I have been driving like this with this sound for a long time and no damage has occurred(that i'm aware off). So my question is after adjusting valves both intake and exhaust to .004 make the exhaust valve loud or is this normal? Motorcycle is a DF250RTC with a CG250 5 speed engine.
Also Yes as you can see engine is running inside my house :S see how quick it starts from cold engine? engine was cold and starts quick which I assume valves are ok? No leaks in exhaust

doesn't it also mean you could have an exhaust air leak from engine to exhaust?
