Ajusted valves = bike starts and dies

[vboulderer]

Hope someone can give some insight.

Just did my valves, got everything back together and now the bike turns over, runs for a few sec. then dies...
Honestly, I'm at a loss. I'm about to start ripping things apart again but figured I'd see if anyone could point me in a good
direction.
Any ideas?

ANd what bike would it be you're talking about?

did you do the vavles yourself or was it a shop?

Some more questions for you:  Assuming you did the valves yourself, how did you go about finding TDC? Did you double check all your measurements?

[vboulderer]

Sorry 02 620

I did all the work.

TDC was established using the dot on the drive timing pulley and the mark on the crank case. All measurements were double checked.

I'm going to be doing mine in the next month or so i'll throw out a couple of ideas as a novice that keep coming up when I do it in my mind. Did you establish that the cylinder you were working on was the one at TDC with the index marks? And what did you change as far as shims?

TDC was established using the dot on the drive timing pulley and the mark on the crank case. All measurements were double checked.

Okay, thats horizontal TDC.  Now what about vertical TDC? 

[vboulderer]

for the vertical cyl. the mark on the pulley was aligned with the mark on the cover.
None of the shims were swapped for new ones as they were all within spec. (double checked with the dealer) but I did remove and replace them in the vertical cyl. since I was in there to get a feel for it.

 

[uclabiker06]

Well I've never done the valves before so I don't know if I can help you any further except to say that perhaps your vertical cylinder was not actually at TDC.

[nomadwarmachine]

Should be fine if you did not actually change anything -- I assume there are no metal-on-metal love sounds emanating from your motor?

[vboulderer]

perhaps your vertical cylinder was not actually at TDC.

when I checked the valves or when I put the belt back on?
And no metal -on- metal make out sessions
oh and thanks for your ideas. 

Right now i'm going a bit crazy trying to figure out where I went wrong.
basically did everything as described in the ducatitech.com / Ca Cycleworks "how to" videos.

If i did some how mess up the timing how would i go about rectifying it

Before pulling your hair out make sure all the basic stuff is OK eg.  kinked fuel line, vacuum leak.

[Rameses]

Make sure your Throttle Position Sensor is plugged in.

Don't ask how I know to suggest that.

the only time i could keep the bike going for more than 30 sec. was if i pulled the fast idle all the way.
if i cranked the throttle it would die almost immediately.

Did you replace the timing belts? If not, why did you remove the belt?
