Hi Guys, I need some help here in Thailand. I have replaced my cam timing chain and somehow got something wrong. I joined the new chain onto the old and wound the new chain on carefully. Once done I made sure that the cam was lined up correctly with the shaft machined slot at 12 o'clock while the pistons were at TDC. I was worried that I may be a tooth off but it looked correct at the time. I riveted the new link on just so and checked again to be sure.
Now I am running a Boyer ignition and PMA unit, all worked well together before I replaced the chain. Engine back in the bike and she won't fire with the timing set at 15 degrees advanced as per the Boyer Instructions. I played and adjusted with it all day and finally got it to start right up with the timing set at about 110 degrees BTDC or about 95 degrees too far advanced.The timing mark is at 9 o'clock position now instead of near the bottom at 6 o'clock as it should be. What would cause this? Did I somehow get the camshaft in upside down?
Thanks in advance for your help. No pun intended.
