Ajusted valves = bike starts and dies

Good advice Eel

You can set timing with a maximum of 2 points on the 620.

What do you mean by "2 points"?

1) Your flywheel has dots on it that can be seen through the sight window

2) The when you take off the timing belt cover you will notice the engine clutch cover has a small line cast into it..

If the double pulley dot matches this line AND the flywheel dot matches the arrow in the sight glass, you're at TDC for the horizontal cylinder..

LOL....I totally forgot about that. 

That is how I aligned mine the first time I did a valve adjustment. Because of how cramped it is for me to go back and forth between the two sides of the bikes when I'm working on them, I quit using those marks on the flywheel about four years ago.

update.

Seems the bike actually has a faulty ECU (according to the dealer...)

how on earth The ECU decided to totally $h!+ the bed the same time i do a valve job I'll never understand.

Anybody here wana call shenanigans?

I dont want to point the finger but I can think of a few things that could potentially cause a problem like you described while performing a valve adjustment (im not pointing the finger, just a statement of possibilities)

1) When you disconnected the battery, you took the incorrect battery terminal off first and shorted it against something (perhaps ECU). Same think for installation

2) I've seen bikes blow a fuse when the battery is connected back again. Before I call BS on the dealer, I would check this out first.

3) Bad luck and its really an ECU issue.

This whole thread has kinda confused me... I wanna try doing the valves with the belts off this time to see if it's any easier for me (12k adjustment time anyways...)  and I was wondering if I can

rotate the cam gears, but not the double pulley,

and when the valve adjust is done just line up the dots again on the two cam pulleys, along with the one on the DOUBLE PULLEY which hasn't been rotated while the belts were off.

This is what i did. According to the dealer everything with my work was fine.  my bike still isn't running... But mechanically it's fine.
