SUZUKIPictures of how I set the timing on the camshaft sprockets and timing chain on my 89-09 Suzuki GS500 motorcycle.


But first, lets pay some bills:

  1. I had the head and cylinder block off to fix the gasket leak and clean up the carbon deposits on the head and pistons. That done, I reinstalled the pistons, reassembled the top end, and pulled the timing chain up through the head.


  2. I removed the signal generator cover, or the right side engine cover, so I could get to the crank bolt and timing marks.

  3. I used a wrench to rotate the crankshaft by the LARGE BOLT, 18mm I think, not the small bolt. The small bolt holds on the signal rotor. The large bolt turns the crankshaft.

  4. I'm looking for top dead center (TDC) on the right piston. When the RT (Right Top) mark is on the rear pickup, that is RTDC, Right piston, Top Dead Center.
    TDC


  5. When the RT mark is on the rear pickup, the LT mark is on the forward pickup. 5 to 15 degree timing advance will not make any difference for setting the timing on the timing chain and cams. The difference is so small it is way less than one link on the chain.

  6. Here are both camshafts and all four camshaft journal holders. A "journal" is the part that the holders hold. The exhaust cam is marked EX and the intake IN. The exhaust also has a worm gear for turning the tachometer cable. Those gear teeth are brittle, so be careful and gentle installing that cam. How do I know? Shut up.

  7. Reinstalled the camshafts and the front timing chain guide.

  8. Here are the camshafts set in place without installing the journal holders.

  9. This is the exhaust cam from the right side of the bike. On the right side of the exhaust camshaft sprocket, mark "↑ 2" (up arrow 2) is at 12 o'clock and mark "1 ↑" (1 up arrow) is at 3 o'clock, even with the head mating suface. The 2 arrow points to this circled chain pin. This is pin # 1.

  10. Now I count to pin # 18. 18 pins is 9 links.

  11. Timing chain pin # 18 is cirlced here. This timing chain pin # 18 gets aligned with the intake camshaft sprocket at timing mark "↑ 3" (up arrow 3). This is the best picture I have. Can't read it? Look in your Factory Service Manual!

  12. Journal holders + Moly paste + Torque. Careful to not damage worm drive on exhaust cam. Careful to install camshaft holders slowly and evenly to not damage camshaft lobes. Even Fleabay camshafts are expensive. How do I know? SHUT UP!


  13. Timing chain tensioner. That is a little screwdriver in my hand. I held the tensioner and screwdriver with one hand, and installed the bolts hand tight with my other hand.

  14. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!


  15. Then I finished my beer.
