1980 GS1000G Rebuild / Update/ Help

[jasonadams74]

Hi Guys,
I finally got my GS1000G back together after replacing the cam dog seal in the bottom half. While out of the frame, I went ahead and replaced all gaskets and seals for the entire engine. I did not remove the buckets on the springs and do anything with the valve springs, I only checked the shims and adjusted them to the right size. The timing is correct, I check it 3 times and did several rotations before putting the cover back on.

Now that everything is back together I am attempting to start the bike, it turns and turns never to fire. I checked the plugs I have spark and I'm spraying starter fluid into the carbs with no airbox. I'm just trying to get it to fire. I'm thinking back to everything I did to this motor, I feel like I put everything back together correctly with help from the manual.

Am I forgetting something? When I spray starter fluid into the carbs, I hear it hissing like it trying to spark. Maybe I've done something and it doesn't have compression?
Looking for answers for a newbie with his first engine rebuild. It's probably something simple.....
Thanks a million.

Cam timing 180 degrees out?

BTW, you should have replace the valve stem seals.

I can always go back in and replace the valve stem seals.
Secondly what do you mean 180 degrees out?

I lined up the timing marks, I pulled the cam chain tight from the front. Inserted the EX gear and lined 1 pointing at / slightly down at the valve cover gasket. Then counting the pins including the pin located above #2, 20 pins back to 3.

Question, there are two "T" marks on this thing. The first T is after the "F" and the second "T" is all the way 180 degrees. Which do I use?

[jasonadams74]

That was it, timing was off. I had it on the wrong "T", needs to be on the "T" for 1-4 cyl
