Looking for the timing inspection port on my '85 1200 ?

Is it the oil filler hole ?

Cheers Bob.

Look on top of the engine block view from left side (opposite from filler hole) the LTD should have a thin vacuum line going to it as well. I can post a pic if you can't find it. Here is a picture of theinspection cap on a carburettored GL1200. The LTD cap is a little different but is in the same location.
What is it u are trying to do?

I changed the the head gasket on the L side (shifetr side) sounds like the timing is off, crank moved as I put the belt back on, lined up the match marks on belts and cam OK ,

Well If you are just lining up the marks then you only have to remove the plug. To use a timing light a clear inspection cap is required or oil will come shooting ot big time when bike is started-ask me how I know!

Here's a pic of my homemade jobbie...

Your camshaft is probably out of time, hopefully not enough to bend a valve.
Just check it by the book now that you know where the TDC mark is.

I must have got the camshaft out of time, it's way off now, when I have the flywheel at the T1 mark.. Does the camshaft timing mark always indicate with each revolution ? in other words, if the timing mark is T1 on the flywheel should the camshaft mark line up each tiem , oreevry 2 revolutions ?

Cheers Bob

The camshaft turns 1/2 as much as the crankshaft so it will be close to the timing marks or about 180 degrees off.

It takes two full turns of the crankshaft to get the camshaft pulley around one full turn.

Thanks-can't take credit as I got the idea on this site.

I took 2 PVC fittings, made a round lens out of plexy with a dremel wheel then a file, o-ring on the wet side of the plexy sandwiched tightly between the 2 pvc pieces. Then used a hacksaw to trim off excess height which allows better clearance and better viewing. FYI threads don't actually match but close enough for a hand tight interference fit that'll keep the oil in the engine. Again not necessary if you are only check the marks with engine not running.

2 crank revolutions per single turn of cams.

Yes it works good, I used lexan and I use a 25mm die on the threads to match the hole, you need to take those threads down to near nothing first and use athe die and make new threads, it's a 3/4 pvc adapter that I used...I used a 15/16" holesaw[special order] and drill press, and sand the edges with a 1" belt sander..a littleso itfits the hole tight, glue it in using pvc glue..nice tight fit so they are pressed in tight on a flat surface..and take an 1/8" off the length too Here's a photo...the oem hastwo lense's this only hs one..Sorry for stepping on your post here...
