SMC will not start. help. - February 16, 2011, 02:54 PM

Now that it is getting warmer, I am revisiting the bike problem and trying to get the SMC running.

I made a thread about this 3 months ago.

Basically, the bike has been sitting in the winter cold. When I tried to start it 3 months ago, it would not turn over. I tried to bump start it back then, with no success.

Today I charged the battery and it is the same thing. It turns over, but doesn't catch.

The battery could be bad and I will pick up a voltmeter today to check, but what else could it be? Any ideas on how to best proceed?

how long did you try to turn it over b4 stoping?
I wonder if fuel made its way to the carb bowl?

you can try shooting it with starter fluid....

unless your battery is turning over ultra weak I don't think its the battery. Other than that...

If the batter is good..you have power..
next is starter...you have that....
next is fuel/ignition/spark....we don't have that....

Does the engine crank over but it just won't start? Where do you live? I might be able to help.

If you are not mechanically inclined I suggest you do this with help from someone who does. Anyhow in simple terms:

1) assuming that your gas has not gone bad, make sure it is flowing to the carbs (disconnect fuel line and make sure it drips if necessary) and check that if you have a petcock that it is on the PRIMER position or on the RESERVE position

2) at the bottom of the carb there normally is a screw to bleed/sample the float bowls, put a CLEAN glass under it, and open the screw until something comes out. Possible scenarios: a) nothing comes out --> go back to making sure gas get there. b) water and gas come out (they do not mix so it would be easy to spot it) --> you have water in your tank, clean it (and the carbs). c) gas comes out --> go to next step

2.1) sometimes the floats can get stuck, tap the float bowl with a piece of wood or plastic to make it vibrate and check again

3) at this point you have gas next u need to check for a spark: remove spark plug cap, remove spark plug, reconnect it to cap, put metal bottom part of spark plug against a NON painted metal part connected to the chassis (normally a bolt or nut). Engage the starter (having no compression it will rev faster than normal) and look for a spark to appear in the sparkplug between the L shaped lip and it's core. It should be clearly visible and it will make a slight sound too. Scenario's: a) no spark --> change spark plug. b) good spark --> your engine might be flooded, keep engaging the starter with no sparkplug, possibly while blowing compressed air in the cylinder for a good 5 secs. Change spark plug (always a good idea in these cases).

REMEMBER: whenever you install a new spark plug, make sure there is no dirt in the housing next to where is sits, if that stuff goes in between the head and the spark plug it's a costly damage. ALSO, it's metal seal will need to be deformed. This translates to the fact that when you put on the new sparkplug, you will need to screw it in all the way, then unscrew it a couple of turn and then screw it in again, you will notice a different feel the second time you screw it as the seal will have reached it's proper shape.

If all this fail I believe you have a problem that might still be an easy fix, but would be beyond the reach of someone with little mechanical skills. At that point, have someone help you ot bring it to a shop.

And don't use starter fluid, it works a lot of times, but it's not too good for an engine with an unknown issue.

1st it is an FI bike, people!!!

Second it has been sitting for long enough that the fuel filter and lines need to be flushed.

Get fresh fuel in it. Get a charged battery in it!

Do not try to bump start this bike trust me! It will not work period!

This comes from owning a 690 for 4 years and 40,000 miles on them.

Also it has been sitting for almost 7 months! You should be shot!!!

If you need real help PM and we can talk over the phone.

I'm going to poke around tomorrow.

On a regular sportbike, I can do a lot of things, but I'm pretty clueless about the SMC. Today was the first time I looked under the seat.

I will get fresh fuel and recharge and recheck the battery to start.

Basically, I've been riding my gsxr during winter and it's a huge pain to work on a bike on the street in the cold, especially since by the time I got back from work it is dark.
