Sorry, but you're completely wrong..... If you look at the diagram, you'll see that the ignition switch puts power to the coil in the side stand relay. The coil operates and closes the switch if the bike is in neutral, or the side stand is up. This switch then puts power through the engine stop switch, starter button & clutch lever switch, to the coil in the starter relay. This allows power to flow to the starter motor. So if ANY of these switches is open, the starter relay will not operate. It's nothing to do with the spark.

Fair enough. I'm wrong.

jonathan180iq? Thanks for point it out anyway.

So we exclude the switch issue. I'm wondering if you guys agree with my guess on the carb? I would give the carb cleaning a try anyway this weekend and see what happens then.

If you're going to focus on the carb, make sure it is flowing gas, before tearing it apart.

Simply pull the main down tube (you'll loose a little dribble of gas) and then hit the starter. The vacuum created by the engine should cause gas to start flowing through the tube. Be prepared for this to happen. Catch it if you want.

If it's not, then you have a vacuum issue, which is usually a degraded hose.

If you feel like your gas is contaminated with too much water, you can always put the thing on PRI and drain it out into a container to use on your lawnmowers or something and then refill with fresh gas.

Yes, the carb is really the weak point on an otherwise good bike. Most problems seem to point to the carb. It's just a pity that Suzuki haven't made any mods to it over the years.

Guys, sorry to bother again.

When I was checking my bike this morning I found the bike is missing two bolts in the front frame right near the engine. I took a picture and try to find it out in the CHASSIS section of the manual, but I couldn't find any detail of this part.

I attached the picture just to make sure it is really missing the bolts here. Your bike do have bolts in here, right?

Yep.Motor mount frame bolt.Just go to the hardware store and get a bolt of the proper length.
:cool:

Or order them, it's parts no. 2 and 4 under "FRAME":

If the starter is whirring, that shows that all the switches are working correctly. That leaves either the spark or the carb. First step is to check the plug. Remove it, reconnect the spark plug lead, & hold the plug against the engine (to get a good ground). Try starting the engine . If the starter whirrs & you see a good spark, then you can eliminate the plug (spark) as the fault, & the problem must (probably!)be with the carb. If there is no spark (or a weak spark) then you need to find out why. (possibly battery?)

There is a third possibility, but very rare, that the starter is not engaging the engine. Can you hear the engine trying to turn over?

Keep us posted, so we can update our assistance. :2tup:
