I have tried many things to fix my versys which refuses to start. Well I have been able to start it once in 20 attempts maybe, but most of the time the battery lose its charge.

However, interestingly enough, once started, it runs pretty well. Go figure.

Here what it does


What I have attempted so far not in a particular order:
1-changed spark plugs,
2-changed oil and oil filter - cleaned air filter and air box,
3-checked valve clearances (twice),
4-checked spark plug coil resistances (ok - coils cracked),
5-checked crankshaft sensor signal (ok),
6-changed crankshaft sensor anyway (for a used one);
7-checked wiring (actually found a few exposed wires around the gas tank and under the seat, fixed);
8-changed ECU for a used one (I really thought it was the issue as it started right after,but problem reappeared)
9-changed one-way starter clutch for a newer one (it actually reduced the nasty noise)
10-Ran the diagnostic but did not find significant info.
11-Changed and charged the battery many times.

If you have a good idea what could be the issue please chime in!

(I have bought and old DR650 - which I like a lot - as I could not find the issue with the Versys, but honestly, the V is irreplaceable:grin2:)

Cheers!

timing might be off, did you remove the cams when you did the valves?

Burnedstar notes that it runs OK on the rare occasion it actually starts:

If the timing were off enough to prevent it from starting, I would think it would never start, or at least run really badly?

Question: When you run it until the battery dies, do you smell unburned gas at the exhaust pipe? That would suggest fuel is flowing, but no spark - an electrical problem.

If no fuel smell, than a fuel delivery problem (which *could* be computer/electrical)

Good luck!

Fuel Pressure or Ignition

The ran once could prove my suggestion as wrong, but do you have #1 plug wire on #1 plug?
Others have suggested fuel, how old is this gas?

Have you checked your fuel system real good? Did not see a mention of that. What kind of fuel setup are you using in the video to try and start? Different ways of doing it on a fuel injected bike, just wondering. I agree with Invader on the starter, sounds horrible. Another question, with all the start attempts, have you thought about changing your start relay? Contacts gotta be in pretty bad shape by now. Anyway, Good Luck and report back.

Its my vote for a fuel problem. Check the list of items the ECU doesn't give fault codes. It is a short list.

Since the bike appears apart, a quick check of the fuel pump is my recommendation. Just remove the pump, and put it in a small bucket of gas. Connect a piece of tubing to the output tube on the fuel pump and apply 12V to the red and black wires. If the flow is any less than a constant, strong stream of fuel, then you may have found the problem.

I just went through a pump failure. To make a long story short, I believe the pickup screen was clogged and that caused the motor to fail.

Hope you find the problem soon!

I have removed the spark plug coils with spark plug connected to its coil and grounded the SP housing then pushed start button. I tested both sides and no problem there - i could see the sparks. From memory (that was almost 2 months back now) I think there was a gas smell but not significant.

Yes, I have checked that too and coils are on the the correct side. The gas was not older than a few days as I have been riding a few times and refueled a week before.

The fuel line (not visible) was still connected to the gas tank (also not visible).

The starter is a good pointer, i'll check that. I have changed the start relay a year ago as it was giving random starter kick while riding at low speed. That was a memorable experience.

Thx all for the good info! Here the next things I'll add to the list:

12-check timing (section 5 - page 24)
13-inspect/change starter ($$$)
14-Check the list of items the ECU doesn't give fault codes
15-check of the fuel pump

Cheers!

That starter motor does not sound OK. If you can bump start it and it runs well stop wasting time elsewhere, it's either the starter, the clutch or something electrical (wiring, grounds, solenoid) preventing enough power to get to the starter.

Here the timing image on my V:

Timing in


Timing Ex


It seems the exhaust sproket is a little off as the alignment mark does not show but is just a little below.

How bad is it?
