Unhappy

I have a manual for the machine but it does not tell which is the exhaust valves and which is the intake valves, also not too clear on finding TDC. Do I need to find seperate TDC for exhaust and then again for intake adjustment? When I look in the timing hole I can't really see any marks.

The exhaust valves are the two at the front of the head (exhaust side) and the intake valves are at the rear (carb side).

Make sure your looking in the right spot, the marks are there. The timing plug is the one right beside the recoil and not the plug on the side of the jug (just incase). Just line the marks up at TDK on the compression stroke.

Thanks, the picture it helped alot. Just getting back to it now, can't get at the hole to look in. Looks like exhaust removal is next. Geez I have a big head......lol

Well, could not find any marks when looking in the hourglass yesterday.....Even the old lady couldn't see anything on the flywheel to go along with the arrow at the top. Must have pulled the thing over as slow as humanly possible for over an hour. That's after going to store and getting a small flashlight of course.

take the recoil off and use a socket and ratchet to turn it over even slower. Someone gave me that tip and it worked.

Thanks alot for the tip, I'll bet it works. Do I adjust both intake and exhaust valves when the marks are lined up? Fueler gauges I bought are too big for the intakes but good for the exhaust, .08 is the smallest they came with. I'll have to check the parts store for smaller 1's. What kind of calistenics does it take to adjust them exhaust valves? Thanks for the help guys, Tom.

heres an honist truth that most any bike shop wont tell you.you dont need the feeler guages just turn the motor over untill the cam lobs are as fare away from giving the rocker arms lift as possible turn your rocker adjusters in untill they tutch the valve stem then back it off 1/4 turn and lock it down without it moving and your done. or you can keep looking for timing marks and feeler guages but your bike shop wouldent

Yes and No to your question, Yes you do set both intake and exhaust when the timing mark is lined up but you have to make sure you are top dead center on the compression stroke and not top dead center on the exhaust stroke.

The way you can tell the difference is there should be a little free play on the exhaust valve( Meaning the rocker is not opening the exhaust valves)

If the exhaust pipe is in the way, you can probably use a mirror to see the timing mark.
