Question about 2001 Suzuki SV 650

1 Answer

The engine turns over and everything but it wont start. no spark

I had my 2001 Suzuki Sv650s in a local bike shop, not sure they knew what they were doing but only ones who worked on Suzukis. they tested everything, got a new stator/pick up coil, cdi, had the carbs cleaned out, and had every wiring connection/wire tested. they said first it was the battery so i bought a new one, then they said it was the pick up coil so i bought a new one, then they said it was the cdi, got a new one and it still didnt work. they tested the coils and said a two inch spark shot out but nothing when they are put back on the bike. really stumped here. they said it was the first bike they have ever had that they couldnt find the problem. can you offer some ideas? maybe something or someway to test it?

I assume you got this fixed; sounds like it wasn't getting gas to the carbs. Some people don't realize the 99-02 SV650 has a vacuum-actuated fuel pump, and sometimes it can get stuck. Mine has had this problem, and it took me a while to determine it was the problem. I would guess it only happens after the bike has been sitting a while.

Best way to check it is to lift the tank (it's bolted to the frame on the right side of the engine just under the tank). Unplug the line toward the front of the motorcycle from the fuel pump, and connect some spare fuel hose to it running to a can next to the bike (don't want to get gas everywhere!). With everything else still connected, crank the bike for a short period to see if any fuel comes out (shouldn't take long). If not, then move backward and ensure fuel will flow from the vacuum-petcock when the bike is cranked. If that does work, your fuel pump needs some work. I was able to take mine apart and unstick it.

I have replaced the battery and ignition unit on my 1985 suzuki 700 es, the bike really sounds like it wants to run but wont start. Starter turns but engine won't kick over. Any Ideas?


Is it getting gas properly? Has it been sitting around for a while? The carburators on motorcycles need to cleaned after sitting around. The jet could be full of varnish. Are you getting spark for sure? Pull out a spark plug and put it in the wire, crank it over and see if the spark plug sparks. When you pulled the plug was it wet at all with gas? Then it probably isn't getting gas right. Just some of the things you could try.

Turn on ignition on my sv650s and nothing, wait 20 seconds and then it starts. The bike starter motor does not activate for the first 20 seconds and then it seems okay. This is happening on all occasions.


This sounds as if it is suppose to happen, a safety device of some sort. The closest freebie manual that I can source is a 2003 one, but it may have the info you need, else contact your local Suzuki outlet, they will know:

Problem starting sv650s


remove spark plugs from block, place tread on block, turn over engine, best if blue, white ok, orange spark is bad, if you are getting orange, your ignition system is weak, usually the coil, and needs to be replaced. also make sure to take out the plugs after attempting to start, andmake sure they are wet and getting fuel.

Bike wont start turn over till batery dies. where


It will have a fuel filter in the fuel line (should be easy to find) but does not have a fuel pump. Firstly i would check you have spark on all cylinders as this is the most likely thing to be going wrong. Once you are sure you have spark you can start trouble shooting fuel and air delivery problems.
To check for spark remove a sparkplug, insert it back into its HT lead. Place the threads of the sparkplug on the engine block and crank the engine. A strong blue spark should be visible.

Bike wont start


I posted this for a similar problem, maybe it can help. Are you sure it's getting gas to the carbs? Some people don't realize the 99-02 SV650 has a vacuum-actuated fuel pump, and sometimes it can get stuck. Mine has had this problem, and it took me a while to determine it was the problem. I would guess it only happens after the bike has been sitting a while (ours unfortunately sat for a year or so without being run).

Best way to check it is to lift the tank (it's bolted to the frame on the right side of the engine just under the tank). Unplug the line toward the front of the motorcycle from the fuel pump, and connect some spare fuel hose to it running to a can next to the bike (don't want to get gas everywhere!). With everything else still connected, crank the bike for a short period to see if any fuel comes out (shouldn't take long).

Back fire on suzuki sv650s


you have to tune your engine using the following ways.
1. tune your fuel air screw for optimal settings.(in most cases inappropriate tuning is the reason for backfires)
2. check and clean your spark plug and the wire connecting your spark plug.
3. check the voltage levels of the battery. if they are low then recharge them.

Bike wont start


I would check for compression on the cylinders. a engine has to have fuel,fire and compression or it wont run. Check the specs to get the operable compression levels.
